1970 Folkestone UK. As a visiting US GI, I loved the many opportunities to enjoy genuine British fish and chips sold on the streets of small villages, served on that day's edition of the Dailey Mail, London newspaper. No such thing as "tarter sauce", just dark vinegar and sometimes mayonnaise. Good eating!
Yeah dark vinegar and salt on fat chunky chip with maybe lemon! In 2005 on Doctor Who Rose said something like I want some chips, not referring to those skinny chip called fried (US) which by the way contain more fat than British chips.
For FTL travel you need fission chips...
TY. I needed that!🤣
Perhaps you could shrink the distance between Point A and Point B with the application of small-ted vinegar on those fission chips.
What about the mushy peas?
For those Americans who don't realize it, chips in the UK is the same as french fries in the USA. Chips in the USA are the same as crisps in the UK. Biscuits in the UK are cookies in America, but they do call the large, softer ones cookies in the UK. Biscuits in the USA are called scones in the UK. Jam in the UK is Jelly, jam, & preserves in the USA. Jelly in the UK is Jello in America. Fish & chips in the UK, is the same thing as a fish fry with french fries in America, but the french fries are usually a bit thicker than those thin McDonald's fries.
A NASA propulsion systems engineer was interviewed a while back. He had done some calculations to get a 1kg (2.2 pound) space craft up to 1% of the speed of light. He said it could be done - just. However it would cost so much that it would bankrupt the whole world. At atmospheric pressure it costs about $10USD in bulk (about $0.40USD/G. He said for a start you would need about 10000 tonnes. That alone would be £4 billion just for the Xenon. You then have to store it at high pressure. Also you have to get it into orbit. At $10,000USD a kilo that's another $100 Billion not including the weight from the cylinders. You then have to get it to the moon or L2 ideally for the actual launch. The total came to over 10 quadrillion USD. IE 10,000 Trillion. Dunno about anyone else but I think that's a lot of lose change.
I’d rather spend the money on fish and chips with mushy peas (and cider)
Luckily we still have cod over on the east side of the pond, always on the menu in fish and chip shops over here. Did not realise you had over fished so much over your side.
Bet them pesky Frenchie's raided their waters like they have ours!.
I used to hang out with friends and chew these things over. Lots of fun. We’d make jokes about paradoxes that could exist if we could do FTL travel if we didn’t pay the cost of the flow of time etc.
A Salt & Battery are still in business. Funnily enough - where I grew up in Scotland, people don't choose Cod & Chips, Haddock is preferred - better flavour. :)
Beat me to it. Haddock was always my preference, unless I was feeling rich and got plaice.
Splendidly clear description of SpaceTime.
I loooove these type of videos from you. I'm amazed no one listened to your podcast.
My mouth is watering after your cod and chips story!! I'm English living in Scotland?!? You can't get cod up here they only sell haddock, in England you can still get cod in some places but the price is through the roof. You pays your money and takes your choice. Keep up the good work!
I live in Monifieth, Scotland. I can get genuine fish and chips by walking for 5 minutes. Best I have had though is either in Arbroath or Anstruther. If you ever make Scotland head to either of these places. I mean I’d take you but you’d hate the company. 😂👍
Fish-and-chips became popular in the States because GI's who had been stationed in England during World War II had developed a taste for it. Flounder-like fish (sole, and plaice) were reportedly in short supply during the war, and the majority of cod were off in deep water that wasn't really accessible due to destroyers and submarines patrolling the North Atlantic, and so the wartime demand for fish-and-chips was purportedly met was met with dogfish, which are a shark species from coastal waters.
Cod is a bit bland for my taste; it's the fish of choice for people who really don't like fish all that much, and was of course once THE choice of fish for religious people to feed their families on meatless Fridays. Fran mentioned "rockfish" which is the colloquial name for striped bass along the mid Atlantic coast, aka "stripers" in New England, which i personally prefer over cod, as it's a little more flavorful. For me, the best tasting fish in New England coastal waters is the Tautog or "blackfish", which eats mostly clams, mussels, oysters, crabs and snails, shell and all (got teeth like chisels!) and has a rich taste from its shellfish diet. A fish sandwich made from Tautog is to die for, but they're not common in fish markets because they can only be caught by rod and reel, since they live around rocks and reefs and shipwrecks where netting them is impossible.
People who are into natural history and food should read the book Cod by Mark Kurlansky , as well as his companion book Salt. These 2 food items literally changed the world in myriad ways. I also recommend The Secret Life of Lobsters; and The Book of Eels (sorry but I cannot remember the authors names). Lobster behavior is far more interesting and complex than you would ever imagine just from looking at them; and eels have a life cycle so complex that we still haven't exactly figured it out, but unfortunately, eels could be headed for extinction also.
Rockfish, in the UK, is not striped bass, it is dog fish, one of the smallest members of the shark family, also known as rock salmon (no idea why, it is nothing like salmon).
Although cod use to be 'the' fish to have in the traditional fish and chip meal, haddock is a much better alternative and has much more flavour,.
Cod and chips with mushy peas-every time for me! Oh, and a few pints of cider to wash it down.
It must be a contractual obligation for fish and chip shop owners to have punnish names. My favourite in the UK was called _The Codfather of Sole,_ though _The Batter Plaice to Be_ came close (can't remember where it was, but the cooking was excellent).
Cod Amongst Men .. up the road from me is a chicken place.. Fryaway Home.
@@PaulaXism Nice. My local favourite managed to resist the temptation: they are on Market Place and didn't go for it! It has been run by Greek Cypriots for the last 40+ years and cooks everything superbly, so we can forgive their prosaic name :~D
Growing up on the shores of Long Island Sound, in addition to ordinary Summer Flounder (aka Fluke) and Winter flounder, we would sometimes catch another member of the flounder or sole family, the Sand Dab, the colloquial name for which was an "Irishman". These fish were so thin that if you held them up to sunlight they were translucent and you could see a little light pass through them. There wasn't enough meat on them to be worth fileting, so we usually threw them back (although sometimes they ended up as lobster-trap bait). My guess is that the slang term for them might have come from the starving Irish immigrants who came here during the potato famine, who were little more than skin and bone.
Those chip shop names do rate pretty high on the punny scale!
My local chippy which is pretty decent to be fair is called New Cod On The Block
Haddock sometimes. Malt vinegar. Mayo for chips
And fried in lard, none of that vegetable oil stuff.
Here in the UK I have haddock and chips, ironically, cooked by a really nice Chinese couple who have done it for years and years. Then when we went to the Isle of Wight we went to a fish and chip shop in Shanklin run by an English couple. It was shit. The fish just tasted really bland with no flavour, the Chinese couple near home are much much much better.
Well, that's Shanklin for you.
IoW isn't the best place for fish & chips, unless you like rock salmon (dogfish).
Hi Fran, if you ever make it over to the UK let me know and I will stand you Fish & Chips to whatever style you want.
So strange to hear Fran discuss Fish 'n Chips! It's a staple takeaway food here in New Zealand since forever. Every suburb in every (and I mean EVERY) city and every town has multiple Fish 'n Chip shops. Blue cod is still available here too. Most kiwis grew up on having Fish 'n Chips at least once a week (maybe a Thurs or Fri) and still do to this day... it's very much a part of the New Zealand cultural identity. It's also kinda sad that, as how unhealthy it can be, it's still one of the cheapest ways to feed a family compared to the cost of meat and veg from the supermarket or compared to other takeaway options (all the various US chains that yes we have here like everywhere else!). Fish 'n chip shops are SO common and ubiquitous I cannot think of any that need to brand themselves with silly names...
Fush n Chups 😉
As an Aussie I concur with what you say Heath. I guess it's our connection with the Brit colonial past. Yep, cod is certainly the best fish but any decent white fish is good too.
Here is Sth Oz, the most common fish used is butterfish (Mulloway) but sadly in these times, butterfish is now what ever is cheap and plentiful - commonly imported Basa.
We've got some good local shops that still peel and cut potato's each day. As always, you get what you pay for. Nothing better than fresh fish and chips, some salt, vinegar and tomatoe sauce for the chips...yum
Here in the UK, Fish & Chips is still the big take out meal. We even still have cod as a primary option.
Now I'm hungry again.
I had some really excellent Fish+Chips at Balmoral Beach in Sydney recently, the place there down on the seafront is terrific
Kia ora, Have you heard some Kiwi say fish and chips? On Skype, my sister and I turned on captions, and I pronounced fish and chips like certain Kiwi's and Skype caption returned it as _fashion shops_
I'm going to Scotland in April to visit family and will definitely be frequenting my favorite Fish and Chips shop in Gourdon, a fishing village about 30 miles south of Aberdeen. The villages fishing boats are literally yards from the kitchen.
Another way to look at the FTL thing is mass accumulation. As an object approaches the speed of light, more and more of the thrust being pushed out the rear is not being turned into forward speed, but into increased mass instead. Eventually, essentially all the engine's power is being turned into mass. Mass is inertia, so more mass requires more thrust which produces more mass, etc. That feedback loop stops further acceleration no matter how much thrust you apply. So, it seems to me the way to go any faster is to shed mass faster than it is being produced by the thrust. Thereby breaking the feedback loop. Since current theory indicates that the the Higgs field give particles their mass, it would appear that lessening the Higgs field ahead of the craft may be a way to "shed" that excess mass allowing us to slip past the light barrier. If not that, some physical or energy shielding that would push through the Higgs field, slicing a path like the bow of a ship in water. Maybe a teflon-like coating that doesn't allow the Higgs field to stick. Anyway I'm thinking something that can negate the Higgs field or cut through it may be the key fo FTL travel.
Damn I was hoping to go to to plad guess we will have to be content breaking the speed of sound 😕 great content Fran definitely put a great spin on my morning
Fried fish in batter originates in Portugal being popular with the Sephardic Jewish refugees. Many Jewish people moved to the UK in the early 1800s and added chips. Dickens mentions chips in A Tale of Two Cities, but they were popular before that. The first fish and chip shops opened in the North of England and the Midlands. At one time there were tens of thousands of such shops, in the small village I lived in in the fifties there were two serving maybe a population of 1,500.
I used to get fish & chips regularly from a local place, but I can no longer walk there and back. Taking the bus can be a pain while carrying hot food, so I don't do it as often. They always had their oil at the right temperature, so the batter was nice and crisp, and the fish just right. They also maid the chips on the day, while most shops used pre-prepared frozen chips which ahve been cut and par-boiled. Makes life easier, but not as nice. A lot of shops don't keep good control of the temp of the oil. If it is not hot enough you get soggy chips and very un-crisp batter!
Loved your take on the speed of light limit. The only way round it involves completely new physics. There isn't anything on the horizon so far. Worm holes and the so-called "Warp drive buble" involve such enormous energies that they would destroy you and your ship.
My recollection is that matter becomes infinite at the speed of light.
The question I recall back in physics was "can information travel faster than the speed of light".
And the answer was no.
The topic making its way through the Ether a few months ago was that the electricity doesn't travel in the wires. My take on that, was that people were wrongly assuming information can travel faster than the speed of light and did not understand the speed of the e-fields and h-fields and transmission line theory completely.
The thing about superluminal travel is that it is a literary device for science fiction. For stories to resonate with humans there must be interaction and conflict between people. If some of those people are from other star systems, then FTL travel is needed for stories to play out on a human time scale. It's literary license that's practically necessary, and used so often that it's familiar, and has become accepted. And some expect it will eventually happen. Some things in SF have come true, but many won't, or can't. Newton's laws of motion still hold. Perpetual motion machines are impossible because the laws of thermodynamics still hold. Relativity, both general and special, are rock solid, and I'm sure the limitations they impose (or, more accurately, describe) on the universe, will continue to hold. No FTL for people, ships, or information, even though the concept is familiar to us.
Isn't the Warp Drive theoretically possible because it creates a shortcut through space, the vessel never actually goes faster then light tho? The problem ofc being that in order to warp space that way, you would need a very unrealistic amount of energy.
Fish and chips. As a Brit, normally have this on a Friday wrapped in paper (now white, but used to be old newspapers) from the local F&C shop with plenty of vinegar. Mmmmmm ... real cod.
You need to try a Buffalo, NY area fish fry dinner with beer battered haddock. Usually only on Friday's.
Time dilation gives rise to one of the great cosmic ironies: the faster you go, the later you'll arrive.
Yeah, the great fish and chips place near my parents old place closed down years ago. Haven't had anything that good since. They do battered fish and chips at the cafe in the building at my work, but it's pretty bad.
When it comes to faster than light travel, you're a real Party Pooper Fran. And the sad thing about what you say about it is, you're absolutely correct. !
Okay, an object that is motion across space at less than the speed of light, is therefore also in motion across the dimension of time, to some degree. Thus the object is in motion in a 4 dimensional sense. It is in motion within the 4 dimensional environment know as Space-Time. The interesting part is that if you add the motion across time, to the motion across space, the total magnitude of motion is identical to the magnitude of motion of which photons of light have, as they move across space. In fact, everything present within Space-Time, moves at that specific magnitude of motion, and does so constantly. All that can be changed, is the direction of which the object is in motion within the 4D Space-Time environment. This provides the simplest explanation as to why nothing can travel faster than the speed of light. Also, if you create a simple geometric representation of this ongoing motion taking place within the 4D space-time, you can use it to derive the Special Relativity mathematical equations, and derive the Lorentz transformation equations, and complete this task in mere minutes.
If you ever come to the UK I'll personally buy you cod and chips. 👍
Miguel Alcubierre proposed (and supplied the math to show ) that a space "bubble" within a "space ship" could remain stationary thus not violating Eisenstein restrictions. In front of the bubble a gravity well could be created and behind a gravity hill thus caryying the bubble forward effectively at ftl "speeds" , sort of a gravity wave that the bubble would surf on. This would give the end result of such a ship effectively moving from one point in space to another without in a much shorter time than a photon would take to traverse it as within it's own frame of reference the ship would been stationary. So effective ftl is possible. The fly in the anointment as with the worm-hole concept is that being able to create this effect requires one of two options [1] incredible amounts of energy to warp the space-time fabric or [2] a technology that causes the same effect without the need for such energy requirements. So for the time being no we can't do it, but someday it may be possible. Anyway keep up the great work you do, being one of those "old" engineers now unemployable I appreciate your takes on things old and new.
Fran you are bringing me back to early 2000s New York. But FYI , the good news is A Salt & Battery and Tea & Sympathy are still there! The menu says that they still use cod. I don’t think the owner of those establishments (and you know how feisty she is) would lie about the products she uses. I love Tea & Sympathy, it’s one of my happy places.
You can still buy cod, but it'll cost you big time. Likely being fished by rod and reel now because the schools are so small and scattered it's not really practical to try to net them.
I havent had Fish And Chips for years either, over here the fish was Flake aka some kind of Shark or part of it. I used to like the Potato Cakes as well, and sometime we would have a real Hamburger with the lot, it had beetroot in it and the buns were toasted. This was in the other place that has Fish and chips aka Australia. Dim Sim's were nice as well, there are quite a few in my small city.
RE: FTL travel. If you can warp space, then FTL is possible in theory. But the energy involved to do this is immense (but not infinite) so FTL is is in theory possible.
The closer you get to travelling at the speed of light, the heavier you become until you’re almost infinitely massive!
My guess is if we can do anything, we would need to use short cuts like wormholes or find ways to do quantum-entanglement communications over very long distances which are faster than light.
@@autohmae Worms holes or black holes and entaglement. Apparently it’s only possible to go back in time to the point where the first time machine was used….I remember reading that somewhere!
Does this mean that I can lose weight by slowing down a bit? *grin*
@@alyssonrowan6835 Well, if you slow down completely, it wouldn’t take long until you weighed nothing at all!
I am curious to know your thoughts on how/why the measured speed of light in historical texts has changed. It is my understanding that is has varied so frequently that that they just fixed it to be a constant but it does in fact have variation over time for unknown reasons. Maybe the density of dark matter around changes which affects the speed of light?
Gravity slows down the speed of light, so does the medium it's passes through. It's slower in the atmosphere than the vacuum of space. It's even slower in water & glass. Except in intense gravity, the amount it slows down is almost imperceptible though.
Maybe if the portal was opened for a jiffy, the energy requirement would be bitty?
`We already know that most of the most distant objects in the observable universe are indeed moving away from us faster than the speed of light & accelerating. We don't know how or why, but we do know there are lots of galaxies moving away from us much faster than the speed of light out there. So faster than light travel is possible & common.
You are mistaking event horizons for motion.
If you happen to be in Whitby (Northeast England) you can get good fish and chips...
Great Video Fran, With your appreciation of Fish and Chips you are giving proof that Pennsylvania is a proper Commonwealth plaice.
Cod still plentiful in England, thank god 🤣 my favourite is battered skate, fish and chips.
Even when going for the wormhole alternative with imaginary clarke-tech to make it feasable. You'd run the risk of essentially breaking causality as you could probably jump to another point in spacetime that may be before you started going there. And things get really messy as we can't really talk about causality without having a timeline based on the speed of light in the first place.
by that I mean, as soon as we get wormholes, we also get time-travel paradoxes. And that in itself is its own kettle of... uhm... worms...
FTL travel is absolutely theoretically possible, even within the confines of established physics. For instance, during the inflationary period shortly after the Big Bang, some objects in the universe were receding from others faster than c. Neither the "nothing can travel faster than the speed of light" nor any of the weird effects from Special Relativity, like time dilation, apply to the fabric of spacetime itself, and it's quite possible to have a scenario in which spacetime is what propels you, which is the basis of most theoretical warp drive models. If there are stable macroscopic wormholes - again, totally possible in theory - this is another means of effectively traveling faster than light. In none of these schemes are there any issues with causality (the so-called "grandfather paradox"), because at no time is anything traveling *through* spacetime at superluminal velocities, and in the case of warp drives in particular, there isn't even any acceleration experienced by the object in motion. Mind you, theoretically possible doesn't mean it will ever happen, but physics certainly doesn't prohibit it despite what Fran said.
Just to clarify, Fran's argument rests solely on the tenets of Special Relativity, which *only* applies to flat (or asymptotically flat) spacetime, whereas General Relativity tells us that spacetime is curved - and that curvature is what permits FTL travel. It may come as a shock, but the effective speed of light in vacuo in curved spacetime isn't even constant. For instance, there's a gravitational phenomenon that causes the effective velocity of a beam of light to slow down near massive objects, not unlike light traveling through a refractive medium. Locally - i.e., over small enough distances where spacetime can be treated as flat - the speed of light is still c; but globally, where curvature becomes significant, it can either be less than or greater than c. In the latter case, however - and this is the real engineering problem - you need negative energy density to create the necessary spacetime curvature for FTL.
Later in life, Einstein stated that he believed light had, at times, travelled at different speeds and regretted not reflecting this in his equation.
This is reflected in some of the cutting edge physics, but the cause (other than gravity) seems to be tied up in some of the supposed 'other dimensons' (i.e. not x, y, z or t) that are sometimes posited.
Frankly, the maths is just too scary for a mere Evil Megagenius™ to contemplate, even with chocolate.
@@alyssonrowan6835 Fooee to contemplation, just go with the chocolate I'd say, who knows for this may lead to a sudden hit, not of energy, but of inspiration...lol
1:33 What I've heard is that if you're travelling at the Speed of Light, time becomes irrelevant
You heard wrong. Time is that which the clocks show and the clock travelling with you will never behave any differently. That's because "you" don't have a velocity. Velocity is always defined between you and a second physical system. As a consequence "your clock" doesn't know that some other part of the universe is traveling fast relatively to you. It simply doesn't care.
Fran ur super smart an unknowingly confirm something I said as a fact
Whoa, whoa, whoooa! Monkfish is leaps and bounds over cod... the best meal of my life was actually Monkfish. They also look cooler. Don't get me wrong, cod was awesome! ...maybe they are non-overlapping fishies, each doing it's own thing best? I used to scubadive and spearfish the monks... cuz the salmons there (Norway) where crazy large, I feared they could drag me into trouble pretty quick because of the deep drop-off's underwater. Good times. A buddy got bitten in his thigh by a monkfish 😂 he had about 15 holes to patch in two semi-circle patterns in his diving suit! That was a laugh because he got safely back to the boat before his whole diving suit was full of seawater so not too dramatic 😂👍
yeah I agree, Cod is amazing but Monkfish is a step above. I especially relish the monk fish liver.
in the UK you actually could your Fish supper wrapped up in proper newspaper! however EU stopped that it has to be wrapped up in unprinted paper it's because of the toner and the Cancer issue!
I thought newspaper ink was made of a nontoxic soy-based ink.
@@goodun2974 I think modern ink is non-toxic, but it comes off easily so the food would get discoloured quickly. Grey chips would not look good!
Salt and Battery is still here in The Village.
I love the dancing around FTL. I suspect we'll find a way by shifting dimensions accidentally.
Yeah, vast amounts of SciFi is about evading Einstein's laws. There's alternate dimensions, warp drives and space folding. Warp drives work by enveloping the ship in bubbles that drag the space along with them. As Fran says, without something to go around Einstein, you can't do light speed+ in normal space.
I see Cod and Chips in the Fish and Chip Shops all the time. It can vary in quality and size a lot, and chips vary wildly. You might find it interesting to just do a search on say 'best fish and chips in Hastings Sussex'. Reading the review comments is they way to go.
There used to be a chippy on Hastings sea front back in the 80's that (in my humble opinion) served the best cod and chips I've ever eaten. The spuds were peeled by hand sitting in a big tub ready to go into the fryer. When ordering cod, or whatever fish you wanted fried, the owner would inform you to take a seat while he fried the fish. He would then dip it in batter then drop it in the fryer...woosh! The oil was always at the right temperature (very hot) When cooked, the batter was lovely and crispy and the cod inside was lovely and fluffy. It would crumble into small chunks when
Oops! Got cut off! Anyway, the cod would flake into chunks. Nice big thick cut chips and a large piece of cod with plenty of salt and vinegar....mmm..m
It's funny how we understand the problem that you can't push something to C, but meanwhile, whatever actual "light" is just effortlessly does it all the time.
I now feel bad. As a Brit, I live about 100 yards from a traditional fish 'n' chips shop here in England, but I don't really care for it (too stodgy). I think I eat it about once a year unless I go to my dad's home town, which was fish-n-chip city (Kingston upon Hull).
But, truth be told, Australians do fish and chips much better (and I expect that New Zealanders do it even better than Australians, but I've never been to NZ).
I think your physics might be twenty years old. I am not clear on the details, but on the quantum level, subatomic particles come into existence and go out of existence all the time. There is also the weirdness of Hawking Radiation that might challenge the old idea of conservation of matter. See also the Casimir Effect, and Quantum Vaccuum.
Fish and Chips :
Reykjavík, Island Drekinn Grill Söluturn is my favourite one.
Really like your channel, but ... as you kinda almost rhetorically ask, ... What is it you do? How would you "define" your channel? -- Anyway. That aside. Thanks for taking me back to my student days in UK. Finish lectures. Quick bit of supper and study. Pub. And then FISH 'N' CHIPS! (In old newspaper back then) YAY!
Incredible videos Fran. Keep on.
I was greedy at the chippy last night, sausage in batter and steak & kidney pie, with a mountain of chips.
I'm going heat up some leftover chips and make myself a huge chip butty.
Indigestion time!
Although I'm American I know basically what a chip butty is, so for those of you who don't, it's a bunch of chips (or "french" fries) wrapped up in a big slice of bread with hot melted butter ladled onto it. A heart attack on a bun!
@@goodun2974 and do not forget to put a ton of salt and malt vinegar on the chips.
If you think that you've put too much salt and vinegar on, you haven't, so splash and sprinkle on some more.
Arguably tastier with white bread.
"Nothing" CAN move faster than light
Eg expansion of the universe
Exactly. Physics is like law... fine print and individual choice of words matters. ;-)
Fran, love ur vids. F Y I, just like the vacuum of space is an absolute ZERO, temperature also has an absolute ZERO. I think(and maybe i'm wrong), that the speed of light is the absolute MAXIMUM a molecule can go. Theoretically, if us squishy meat servo humans are able to make machine to get close to the speed of light, we will be crushed be the enormous force. U need a 10 million mile run just to get us humans up to half speed, and then u have to brake again because reached ur destination. Much LV
Blimey Fran!! No decent fish and chips since 2007!
What’s the word coming too?
Wormhole disengaged, ha. I love your talk on physics, but history teaches me something more: that as time passes and science develops, paradigms shift, limitations are overcome, and what seemed impossible becomes in fact the new paradigm. It was the case with Newtonian mechanics, and at some point it may be with relativity. We just haven't reached the point where we could even test if there was something beyond what Einstein said.
Hopefully the chip shortages won't apply to fish&chips :)
The fundamental laws of the universe do not change because of innovation, and Newtonian physics guides our interplanetary spacecraft today.
@@FranLab in the light of modern science, these laws are fundamental, but I can't rule out the possibility that they're yet another horizon, and the humankind's view doesn't grasp the entire complexity, some constructions may be wrong after all. It's just that our current science doesn't have the means to get even close, let alone test its limitations. When Jules Verne wrote his works, there were no submarines or moon travel either. A few more decades and BAM! Here we go. So, I'm kinda agnostic about it, respecting the current scientific consensus on one hand, but accepting the possibility of expanding it in the future :)
@@FranLab But... our understanding of "fundamental laws of the Universe" DOES change.

The best chips in my home city are often cooked by Greek people.
The salient point is relative speed. Speed is scalar. The whole thing about relativity is exactly that. It''s relative,. There is no zenith, no reference,
👍
Artificial avatars could be sent star to star, in a few centuries if we don't destroy ourselves. Would not matter how long these would take. Once there they could report back information by some wavelength of light. I remain optimistic as I grow older that the gaps between stars will somehow be crossed eventually. Even without interstellar drives, a solar system remains to be explored and inhabited.
Fish n chips is awesome if it's fresh Hawaiian ono!
Why is there a famous equation using the value ( speed of light × speed of light ) .??
And also, what is the definition of "Light" ?
Observable to human eyes?
Observable with human built tools?
Mesurable with human made devices, yet non visible?
The recently late UK comedian Barry Cryer once pondered the question 'If you could go faster than the speed of light, would your headlights go out?'
No, but they wouldn't light your path.
Remember the Cod Wars?
2:36 "there's not enough energy in the universe to get a physical particle to travel at the speed of light" never say never Francesca..if there's one thing we know, it's that we don't know what we don't know
Well, that would require infinite energy and the universe doesn't have infinite energy (nor would we be able to harness even a minuscule fraction of the energy it does have, that would be like taking the heat out of every star in existence for starters). And that only illustrates the energy side of it it you theoretically tried to accelerate a particle to light speed.
The best way to explain it is that it's more like a universal constant where time and distance doesn't even exist for the particle rather than what you might think of conventionally as simply some kind of speed record that hasn't been broken yet.
@@Roger__Wilco roger that, same thing we've been taught since the 1905 theory by a man who could not remember his own ph# & married his 1st cousin. Not that I'm doubting in any away AE's genius, I'm just amazed how so many people totally give up based on relativity. What's to say we can't possibly travel at say .9 the SOL?
@@CARLiCON No, there's been a lot happening since he was around. Simply recognizing massive limitations of one thing (trying to transport matter across vast interstellar distances by accelerating it to light speed or even near light speed) and acknowledging that an alternative might have to be discovered is not giving up, it's more like the opposite and Fran put it pretty well on other things that could be considered.
I recently heard that the cosmos is traveling outward faster than the speed of light!
"Traveling outward" into what, exactly?
@@gotherecom Empty space.
Isn't quantum tunneling faster than the speed of light/superluminal? From what I've read, the exact speed of quantum tunneling has not been measured (too fast for our capabilities), but has been measured to be faster than the speed of light.
Isn't that only about it might be faster then the speed of light of the materlial the quantum tunneling takes place in, but not faster then the speed of light in vacuum?
Speed of causality
There wsd a fish and chips place in Florida around 1980 that supposedly sold " true" fish and chips . They served them in a paper cone. I forgot the name of the place...at the time, Florida was just brimming over with seafood places.
I read an article about a " warp bubble" being possible. The math allowed for it, but how well this translates into reality hasn't been established.
Still lots of great, fresh fish to be had in the Keys. I try to visit a couple of times a year, and eat nothing but while I'm there.
BTW, you can get fresh cod at markets in NYC -- but it costs more than steak. No Fish & Chips joint is likely to be using it.
Propper Fish n' Chips should be battered and deep fried, the chips on yesterdays newspaper, and lots of salt & vinigar eaten with a wooken fork.
wooden fork?.. luxury!.. fingers lad.. fingers..
@@PaulaXism The chipies were too hot for my young little fingers. Was a long time ago.
@@PaulaXism , yup, gotta be fingers!
Of course quantum mechanics don't necessarily apply to traditional views of matter as we know it so until we unite the two, who knows. There may even be mechanics beyond "quantum" that have yet to be discovered. Even if the universe is not infinite, it might as well be from our standpoint which means "infinite" possibilities.
From that, we need to familiarise ourselves with the current diffinitions of the terms of reference that helps to explain physics...what you are explaining is outside the scope of most citizens understanding.
It is not a pure exchange of matter into energy or e to m, there is loss all the way through...due to our imperfect world.
In a vacuum with no gravity, a object should be able to reach near light speeds, with little energy spent.
A electromagnetic impulse travels at the speed of light and carries energy with it, although not to cause harm (radio waves), but some do like EMP weapons.
It's all in the mind y'know.
Accelerate to a high enough velocity and the crew will experience time slower
Thus making it possible to traverse the Milky way in a single lifetime.
(Everyone on Earth will die but the crew will still be young)
not at this time is it possible , maybe in the future, I know how just cant explain it
fran, are you a physicist?
Mult vinegar, ketchup, or mayo(really)?
Mayo, with soy sauce.

Can literally drive down my street and buy cod fish 'n' chips. Welcome to the North East of England.
How long is your street that you have drive to the chippy? I walk to mine.
There's exactly one way to travel the speed of light... You just have to convert the matter to energy, which means that the matter no longer exists...
A brain is information organized as matter. If that information can be transferred to EM waves, brains could travel at the speed of light. At the target location, the information could be transferred back to matter.
@@NuntiusLegis unfortunately, just like in Star Trek, you die in the process.
@@AndrewKroll Most matter in our bodies is exchanged over time. If you look at your hand, perhaps it does not contain any of the atoms of your hand from a decade ago anymore. Does that mean your hand has died?
@@NuntiusLegis no, those cells died, they also didn't get converted directly to energy.
@@AndrewKroll But the matter of your hand got transformed into different matter. You still call this your hand. Why should some travel in the form of energy in between make a difference, as long as the information that defines your hand - or brain - stays intact.
So how come they can travel at warp speed on the enterprise!?
Folding space locally.
Sorry to contradict 2:33 but "99.9999... to infinity" is mathematically 100.
It is mathematically not 100.
People worry about black holes sucking up everything in the universe eventually.. the funny thing is.. nothing can actually ever cross the event horizon.. not in the lifetime of this universe anyway... to an outside observer of course..
The word "impossible" is only found in the dictionary of fools.

@@goodun2974 plasma has too much noise. All static.
Ahh, sad: the days of fish and chips in newspaper - salt and vinegar on the side - are gone :-(
and they took the arsenic poisoning with them.. printers ink for newspapers was nasty stuff.
If you could slow to a stop could you see the end of the universe
Fran my warp bubble can travel faster than light and stay within the confinds of physics....
"And we can fly, high as a kite if you want to /faster than light if you want to /speeding through the universe/ thinking is the best way to travel...." The Moody Blues
@@goodun2974 We ride the waves
Distance is gone, will we find out?
How life began, will we find out?
Speeding through the universe
Thinking is the best way to travel.. Cracking song..
Genuine question. If nothing can travel at the speed of light, how can light, which is made up of photons travel at the speed of light?
Photons have no mass, and at the speed of light are a wave, not a particle.
@@FranLab Thank you for that. I owe you some proper fish 'N' chips (and mushy peas) X
1. In my lifetime, it was KNOWN that aircraft couldn't travel faster than sound, because aircraft couldn't fly faster than sound. It was a "fundamental law of the Universe".
2. Please give an example of energy ever being turned into matter.
3. If you are ever out in San Diego, I will buy you a wild-caught salmon and chips meal.
✌
1. The objections to hypersonic travel were engineering objections, not "fundamental law of the Universe" objections.
2. Virtual particle pairs are spontaneously coming into existence all the time.
In the big bang, there was just energy. So any matter that exists once was energy that was turned into matter.
@@nasabear 1. On 14 October 1947 I was only 4 mo. old. Before that it was widely known as The Sound BARRIER.
2. VIRTUAL particle pairs, half of which are anti-matter. (+1) + (-1) =0
Everything in the Universe is STILL only energy, giving us the ILLUSION of matter.
@@NuntiusLegis Everything in the Universe is STILL only energy, giving us the ILLUSION of matter.
Yes Fran you right nothing can travel faster than light but you need to look up the new Worp drive thery that has been out for a few years now! It's not quite how Star Trek does it but it could work in thery!
Poor fish. We shouldn't make fools of ourselves by thinking about interstellar travel as long as we still munch on our fellow sentient beings.
yum, whoops
Sounds like Fran needs a field trip to the UK and eat fresh fish and chips by the sea in old Blighty ! I can recommend Weymouth and West Bay in Dorset for great sea food and the Fish and Chips. Or come to Somerset and try the Chips in Yeovil.
