Arthur C. Clarke: “Two possibilities exist: Either we are alone in the Universe or we are not. Both are equally terrifying.”
Hey! I too, am a texas math teacher! Ntmu lol 😆
@@corpsycrystal5045 awesome.
Great quote. I honestly don't know what's worse. We are it. Or we are not.
It's also possible there is no outer space at all. What if we're all brains in vats hooked up to a computer, and this is all a simulation?
Either we’ll know it in our lifetime or we won’t which is both terrifying.
I love Millie but she lost me for a second when she was talking about Mars. Yes Mars is round like the Earth. You won't fall off of it. She is the best ❤❤❤
Right, I was so lost 😂, we love u Millie!!!
Who knew she was a flat earther?
That's just an enduring myth. Mars is actually shaped like a banana.
Millie is President of the Flat Mars Society 😂
I think she meant like if you were on the bottom of mars, if it had less gravity wouldn’t you just keep going if you jumped and you would fall away from mars, it doesn’t really make sense bc there is no up or down in space but I don’t think she was saying mars was flat or anything
Millie was genuinely astonished at the whole idea of how big the universe is. You could see the wheels turning.
i'm a bit concerned i exist on this planet with other adults who don't know this.
@@mikemath9508 to be fair there is no way to really know this stuff until you're taught about it
@@ville666sora you are right, ville vallo from my favorite band
I've watched this a few dozen times. Still boggles the mind how small we actually are
Speak for yourself.
I don't see it that way - we are normal (for us), so it's just that space is ginormous.
@@fordp69 That's the thing though. You're using the human scale because it's hard to quantify the universe's size. Try to look for a human standing in a field while you're on a plane at 30,000 feet. Normal parameters within our own atmosphere and that would be almost impossible to do. We're just grain of sand on a huge beach
@@T_WILL77 But why do I care? I mean, I care about science, and I know there are good people looking at everything, I am an expert in computers, and I've worked with a few scientists. I care about humanity, and have often given to support that. But why do I care that the universe is ginormous? I enjoy reading and learning about what we discover, but how does that effect my life? If they discover something that effects here, then I am interested, but I can't do much about it.
Highly suggest visiting an area that has very little light pollution and just looking at the sky and seeing our Milky Way overhead. I traveled through the middle of Australia and we just camped out in the outback and it was one of the most beautiful things I've ever seen.
The most amazing thing about the “tiny little dot” in space was not the earth, it was voyager taking the picture and sending it home.
I wonder how long the image took to be sent back
@@swishersweet1322 since it’s light speed,
I wanna say maybe 2 days? Idk how far it was and I can’t calculate but it’s just a guess 💀
@@infamous_richard8732 Everybody at NASA waiting on a ding just like a microwave
@@swishersweet1322 It took days to complete the transfer, IIRC.
sure it did... V-ger has been out of the solar system for years but it's solar panels with 1970s tech and the nearest star is still Sol and that is so bright out there past Pluto... anyway they are still powering the battery on board to modem (more 70s tech) data back to Earth. Seriously the transmitter on Voyager should be linked to every cell tower on Earth so I can get more than 3 bars in downtown Mobile.
Am I the only one laughing hysterically listening to James compare everything to text speed, because we lived when there was no text, no cell phones, and no computers, just dial phones and snail mail, my how points of perspective have changed.
It still runs at the same speed. (through space)😁
Yes, you are the only one laughing historically. The rest of us were laughing hysterically.
@@itsahellofaname awww, killed by auto spell once again. Thanks for correcting this
"The Martian" is an excellent movie which gives a realistic picture of the time and effort it takes to do a trip to Mars.
Only 2 inaccuracies in the Martian. Storms don't get that violent, and the soil is toxic. We didn't know about the soil when it was written.
@@cpob2013 Imagine Martian storms in the movies though, that's not dramatic at all. /s I beg to differ on the composition of the soil though. Especially since it needed phosphorus from the human waste. Martian regolith can be determined by spectrometry.
Haven't seen the movie (yet), but I'm currently reading the novel, and it's a blast! Definitely recommend reading the book.
@@XaeeD The novel is great! 100% recommend. I wouldn't go into the movie thinking it's accurate to the written form but it's still lots of fun.
“Space is big. You just won't believe how vastly, hugely, mind-bogglingly big it is. I mean, you may think it's a long way down the road to the chemist's, but that's just peanuts to space.”

All you need to know is, the number 42.
Here is a frood who knows where his towel is.
Great book, terrible movie.
@@crowttubebot3075 Yes, and thank you. ;-)
If existence is this large, there are definitely worlds with intelligent life somewhere out there
or we just have luck to exist
You only have half the equation there. Say you roll 12 dice. Odds are high that at least one will come up as 6, right? Well you don't know how many sides the dice have. Could be 100 sided dice for all you know. Are the odds still good? We don't know how likely life is to form.
IM FEEL HELPLESS YOU WATCH WHOLE ENTIRE UNIVERSE ITS SCARIER THAN HORROR MOVIE BECAUSE THERE ARE JUST TOO MANY PLANETS EXIST
I watched this video 2yrs ago and it changed my life. The fact that other stars host planets which could have life is mind blowing. It's my hope that humanity will detect other life out there atleast in my lifetime.
You won't fall off the edge of Mars. But if an object is small enough, you could escape it's gravity and fall off. Well, technically, you can't fall off anything in space. There's no up or down. You'd just float away into the vacuum of space 😳
Yeah, it's more like you de-attach
woooo dude
The Expanse, don’t want to get spaced now do we? 😎
I'm trying really hard to not make a "your mom" joke right now.
It’s not about how small the object is. It’s about how fast it’s traveling. For a planet or moon with less gravity you don’t have to go as fast to reach “escape velocity” which is the speed and therefore momentum necessary that you won’t eventually get dragged back in by the gravity of the planet.
With Millie at the helm all of a sudden the universe has order and now makes sense
I think the terrifying thing about space and time is, that there might be places we can see now, and never be able to reach. And also, the opposite applies.
The crazy thing about being on a planet with different gravity is that it’s not like you just lost weight and are lighter. You still have the same mass and so have the same inertial momentum when you are moving. So it’s still takes just as much force to get your body moving, there’s just not as much force pulling you down, so it can actually be difficult to walk as you have less frictional grip on the ground, but still need just as much force to move you forward.
when they think they can see the size of the universe at 13-14 billion years away. it just means that it took 13- 14 billion years for the light to reach us. but with the great expansion those galaxies are probably now like 30 to 45 billion light years away. and speaking of expansion, its not that the universe is spreading out. its spreading out in between everything. hope i said that right.
This cosmic understanding has helped me through out my life to keep things in perspective concerning just what's important. We're just a speck.
I feel after watching this it makes us feel like a miracle nd special and we should live everyday as wot it is a gift while we have it. Have a good day everyone ❤🎉
He gave you the seat. He already knew you'd be married lol
The REAL definition of gravity: a conspiracy amoung brassiere manufacturers.
I think the last words in this video are the most important "discover TOGETHER". Imagine what humanity would achieve if we all finally learned to work together and not against each other.
In a nutshell, we can do all the mathematical calculations, run all the computer simulations, use countless illustrations of various types, but the human mind still cannot truly appreciate, fathom nor comprehend the astounding distances, sizes and masses (of objects) that make up the universe. Everything we know, after thousands of years, was learned from observations right here on Earth or from the most infinitesimal distances (comparatively speaking) away from Earth. Even a size comparative illustration of the Earth next to the Sun does little to convey the true enormity of the Sun or its mass, and then consider that the Sun is a "Dwarf Star" that is equally as small as the Earth when compared to many other stars.
Take for example, the north star "Polaris". Comparing the size of our sun (Sol) next to "Polaris-A" would be similar to placing a marble (or possibly a golf ball) next to a basketball. Then consider that Polaris is approximately 323 light years away. That means when we see the north star in the sky at night, we're seeing what it looked like on this day 323 years ago! In essence, we're looking back in time! Also, imagine if we could travel at the speed of light (roughly 186,282 miles per second - an impossibility according to physics); it would take us 323 years to reach Polaris! Even if we could travel 10x that fast (Warp factor 10), it would still take over 32 years to reach it! The distances and sizes in "Space" are just incomprehensible! Amazing stuff, no?! 😮 And just for good measure I'll toss this in. Everything in our universe is made up of atoms. Atoms are made up predominantly of empty space. Therefore everything we see and touch is made up mostly of empty space. Because protons, electrons and neutrons revolve infinitely fast around the nuclei of atoms, they merely give us the illusion of mass (or solid objects e.g., a floor, a vase, a mountain, etc.). Let that sink in a while! 😂Peace.
Peace be upon u too.
Just a queries Sun= dwarf star?? Was Undr T Imprsn that it was a medium sized star. .? You sir need to Open the Quran and check out some Scientific Facts in there that will probably baffle u as to how the information got there....
Just a coincidence; there is a Chapter called the Bee in there as well.
...
...
Also a Chapter called Ant...
....
....
And also one called Iron.
....
Reason I pointed the particular Chapters is because they are amongst many that contain those Scientific proven Facts in there....
I am talking established Fats now and not "Theories", that are by default subject to change.
"The Expanse" is a tv science fiction series in which some aspects of space travel and life in space are treated realistically, in particular gravity, and the time it takes for radio signals to travel across the gravity. It's a great story too.
the books are very good as well
Underrated and one of the most realistic space travel shows.
Talking about universes, Seeing you guys swap places is unsettling, like everything is almost normal, but im in an alternate universe lol
Millie has always been in charge...LOL. Good for you on taking charge in your proper chair
Loved the brutal, insignificant comment at the end, it's why I just subscribed. 🤣
Glad to see you guys are back! Love your videos :)
Being from the US, I love your accents!! Greetings from NY :)
Love to see the BOSS in the big chair.
Love you guys, great couple, love your reactions ❤ 👍
Oddly enough when you solo reacted to this video years ago that was the first video on your channel I watched and got me subscribed to you.
6:26 Also know that that timeline works for a "Mayday" call as well. When you're that far out, there is no help. Maybe one day there will be support stations and such that don't exist now.
They get the asteroid belt wrong also in movies. The asteroids are over two miles apart. Neil the space guy said you could walk or drive thru it, blindfolded, and never hit an asteroid.
That dude must be dumb. You can't walk or drive through space.
FINALLY!!! Millie is in charge! Praise the Lord!
Communications in space will be just like letters from hundreds of years ago…You would write a letter asking how things are and give your side of the story and send, then maybe in a few weeks or months you would get a letter back. Rinse and repeat. We’ve been communicating like that for several thousand years, it’s only in the last 80 or so years that we’ve gotten used to instant communication.
Love this video! Thanks for reacting to it!
A sad bit of trivia: The first radio signal with the strength to actually broadcast beyond Earth was unfortunately made by Adolf Hitler. Which means it’s possible that the first message aliens would get from-about earth & earthlings was potentially from a total dick.
"mai Kya Karu, fir job chod dun"?
Is the universal answer of these types of videos 😆
Welcome to the Universe. Please stay with your tour group. You REALLY don't want to get lost...
oh boy I've been waiting for this one since you did the history of the world Thanks so much.
really enjoyed it. I think I've watched it a dozen times myself I hope you watch it again You really pick up new stuff every time just like with that history of the world I think I've seen that more than a dozen times too
Switchin' it up.! You crazy kids!
Lmao her genuine confusion about the shape of mars
I always loved that video--completely mind blown. Saturn is definitely my favorite. If we pronounced Uranus the right way (oor-ah-noos) it wouldn't be so funny. Great job in the driver's chair, Millie!
Really like the sharing the hosting!
Watching now but so reminds me of when I was about 16 I looked at my dad and went "Dad, how can the universe be infinite but if it's not then what so basically it still goes on forever but hows that possible" His answer as usual spot on " forget you ever thought about that if you ever want to sleep again at night" He was right, the ridiculous amount of times I sit up at night just going " wait...."
The scale of the universe is absolutely incomprehensible to the human mind. We just didn't evolve in an environment that gives us any perspective on such huge distances.
For as long as humans have existed people were asking themselves "Where did we come from", "How was this world created", "What is in the heavens?" And we live in the first few generations in history that can factually answer that we now know at least some of the true answers to those questions.
Like the person above said. Our minds literally aernt capable of comprehending the scale of the universe. Like the video said. It is gonna take 30,000 years just for our probe to get out of our own solar system.
Mars rovers have internal navigational systems so they don't fall off the edge of cliffs, which we might not have time to see and correct for given the delay if we were driving them completely manually. They made a huge deal about it at the time and is probably what you're confusing with falling of the edge of the planet
Great picture of you two on the wall!
I think it's both comforting and terrifying to know that our lives don't really mean much in the grand scheme of things. That the struggles and issues in our lives may seem big but really aren't, compared to everything out there.
I find it almost terrifying that someone involved in this life can pretend that it is small or meaningless based on something as simple as size. I mean an oxygen molecule isn't very large but without them you die. H2O molecules are not large but without water you die. Pretending that overall something as simple as size determines value is really weak
@@yrntthelibswipedofftheeart16 I'm not saying that life doesn't have value, it absolutely does, both to the person involved and to the people around them. I'm not a nihilist. What I'm saying is it's a reminder that our problems are fairly insignificant in the grand design.
We are in the upside down! Love the channel!
I was 11 when we landed on the Moon in 1969. It's really hard to believe that the computers on the command and lunar only held aprox 25 mgb of memory. They had to load each stage of the mission. The blast off, the trip towards the moon, landing and returning. It boggles the mind how non advanced we were and we thought it was state of the art back then.
I worked at NASA for 7 years from the late 70's to the mid-80's and have been in computers ever since, I know all about it ;-)
@@fordp69 Crazy, my uncle was in to computers whatever was pre-WWW in the 80s.
I heard smartphones alone have more computing power than the power it took for the module to land humans on the Moon. So every teen in Highschool has more computing power than the moon landing. Imagine that...
I was 7 and now I’m lost.
@@S1D3W1ND3R015 The computers on the ground came up with coordinates, the computer on board could only fly from one coordinate to the next, or do other procedures.
Science facts, yay. Happy New Year
Millies thinking of the bends and that happens because of pressure under the water you can’t rise too quickly otherwise you get
“The Bends”
Well I'm glad I'm here on this teeny tiny dot that has such a diverse population. I just wish we ALL took better care of her. She's all we got! And you thought the USA was big...Lol!
To answer your question on gravity its pulls to the center of the planet, all planets have it and if i remember right the bigger the planet the stronger the pull so you will feel heavier on a bigger planet and lighter on a smaller one.
Also in space there is no right side up or upside down.
Didn't even watch yet and i liked your vid lmao you guys never fail to entertain! Love from 🇺🇸!
You're correct. Going to the space station has a time length for your service. Three months, a year, or whatever. I don't know how long. Going to the moon is a single shot. Go, do work, and come back, the end.
7:50 To better understand "orbiting" around a planet vs gravity and sticking to it....Imagine if you were on a cliff and jumped. You'll eventually hit the ground due to gravity. Now imagine you make a taller cliff and could jump really far off of it. You almost hit the ground but because you were so high up and jumped off really far ---> this way direction that as you approach the ground you're missing it because the world in a sphere. What you're doing is essentially falling forever. Going around and around the planet. The gravity is pulling you down but you're also so high up that you're falling in parellel to the earth's curved surface. That's "orbiting" If you were to jump any lower and had no sideways velocity then you would get sucked straight back down to earth.
Falling fast enough that you fall past the edge of earth...forever
Imagine looking at the moon knowing that a couple dead people were there. Luckily that didn't happen.
That's wild and crazy to think about
Yeah when I see this sort of thing I think that it is almost a certainty that there are aliens out there but given how far away everything is, it's likely that we'll never meet them - we'd have to invent some sort of warp drive like in star trek to even have a chance
Ngl this was A LOT to take in!! Like low key scary in a way. It’s crazy bc like I knew in the back of my mind that the Universe is HUGE but when it’s put into a visual it made me feel microscopic sized.
Hard to beleave that man has even got that far out with the satalites taking pictures and sending them back to earth
Millie in the hot seat - Love it !
I have a degree in astrophysics, so I think about this sort of thing a lot. Even so, thinking about the enormity of the universe always boggles my mind!
Is that a prerequisite for mindboggling?
Bro I just graduated high-school and want to get a degree in astronomy is it worth it?
I don't have a degree in astrophysics, but it's one of my most beloved subjects and it sure doesn't help with existential anxiety (or whatever you call it). Imagining I'll stop existing one day is terrifying enough, but the fact that the universe will cease to exist at one point is beyond terrifying.
@@Inferiis it’s not really scary to me it’s beautiful that we even exist
Our sun will die before we could reach another galaxy. That's why I love Star Trek. Possible warp speed and folding time. Using man made black holes to travel. We live only 80 years on average. So make the best of your life and believe there is an afterlife. Good video.
Astronomy major here, the scale of the universe is humbling
There's a bit of woo near the end of that video. The term "speed of light" is used for the absolute speed limit of the universe. There's more to it, but nothing can be outside the observable universe, because nothing can move faster than the light we see coming from it.
No, *there is* matter outside of our observable universe, we just can't see it because light hasn't reached it yet.
I am a little surprised as a teacher she just asked if there is gravity on the moon. YIKES!
Damn.
That puts shyt into perspective.
"Bloody hell! We're small!" Ahh accent
Usually things of this scope is not taught in school. Atmost one would learn about our own galaxy and the age of universe. But further knowledge is only taught in undergrad and grad school.
A still: we are in size several magnitudes closer to the size of the observable universe than we are to the smallest possible distance: a plank length. Meaning we are bigger compared to the smallest (possible) thing, than the biggest (observed) thing is to us.
There's a great book by an LDS author that shows that there's perfect harmony between the prophetic statements concerning the garden of Eden being in Missouri and the Old Testament account concerning the garden of Eden. It's called Canaan, Babylon, and Egypt A Comparative Theological Analysis on Creation sold by Eborn Books.
You would absolutely love Fun to Imagine with Richard Feynman
2:44 I can't imagine how alone you must feel looking at Earth from the moon
Yes, we are all around the Earth. People on the other side of the world are upside down. Gravity always pulls you inward. In space there is no up or down
So about the gravity question. There is a video explaining how a humans physiology might develop differently if they were born on other planets in our solar system. For example, Mars has a lower gravity (3.721 m/s²) than Earth (9.807 m/s²), so a human would more than likey have a "stretched" bone structure compared to what we know on Earth.
This is the video I was talking about: th-cam.com/video/GwM4Jg9ChvM/w-d-xo.html
Ohh favorite planet is 55 Cancri e. Although OGLE-TR-56b would be an awesome planet to take a vacation on. I hear the rain there is something else.
The fact still remains that we are finite in intelligence, logic, reason and imagination.
at 25 seconds in .. I had to say .. "YESSSSS!!" .... the pretty one is up front today
Favourite planet? Currently WASP-121b where it rains rubies. Ok, technically it is an exoplanet but it still counts.
Oh and Millie there is no “UP”in space UP is in every direction so that is something else to think of too !!!
Hello from Florida USA!! Absolutely love your channel! What a pleasant surprise to see Millie up front. Fabulous! May I suggest watching the movie The Martian staring Matt Damon. Very interesting to think about being stranded on another planet. Love all of your videos, especially the cooking pecan pie!!! Love from across our little planet!!
Dear Ms. Millie, to your questions ....it took the Apollo crews 3 days to get to the Moon, even atop that large Saturn V rocket. ...The Moon's gravity is 1/6 your present weight. .....Mars, lets see .. Have you seen the pictures of Goldstone Tracking Array? If you have heard of the law of diminishing return, a sound, radio wave, as it travels over a measured distance, becomes half power, with each further same distance away. 10 watts, 5 watts, 2 1.2 watts, and so on, so all those antennae get trained, directed, where to look for any signal of a determined power from the sending origin. ... your weight is approximately 1/4 you are now. ... as all the Mars landers arrived, descended and landed on the planet's surface, even with video, here at the control center, they already had everything calculated and a copy of the lander's programming, as to what second this or that should happen, so when it did, they were relieved but for the next event of the schedule. And to think, as far as Mars is from the Sun, the landers have used solar panels to recharge their batteries. In contrast, the Voyager and Pioneer probes are using a very small nuclear power source, so when they say the instruments might not be working after a while, it is because they have lived their usefulness, not because of a power problem.
I hope that this has helped.
Crazy to think that it would take us around around 37 200 years just to travel one light year. We can’t even travel to the nearest star, except for the sun, as it lies about 4 light years from earth.
Millie, good to see you're more comfortable with us to sit in the hot seat. Lol
The space between the earth and the moon is big enough that you can fit every planet in our solar system, in that space and still have some room left over.
It took the Apollo spacecraft approximately 3 days to travel from yhe Earth to the moon, each way. The first landing, Apollo 11, was on the surface for about 22 hours. The last landing, Apollo 17, was on the surface for about 3 days.
Gravity on the surface of the moon is about 1/6 the strength of the Earth's surface gravity.
2:30 It takes roughly 2-3 days to go to the moon and 2-3 days to come back. Idk how long astronauts ever stayed on the moon, but it's probably something like a day max 🤔. So basically a week to go and come back 🤷♂️.
What is 'mental' is that you could talk to someone on Mars. 200 years ago you couldn't talk to someone 1 mile away.
Liked and subbed, because you made me 15:00
Just kidding, you guys are nice to watch. I enjoy you exploring your curiosity and discussing / learning as you go.
Keep up the good work
So we put the Smarter person in front? She is the one who knew you do not put the full koolaid packet in a small water bottle and no sugar. Good move!
Definitely mind blowing…. They are worrying about other galaxies etc. but we can’t even control what happens on Earth….yup I’m thinking us Earthlings need to get over ourselves
If the universe is a Googel plex meter across it is mathematical guaranteed you have a doppelganger somewhere in the universe.
Love the idea that they think there is gravity on the moon.
The majority of what about the Universe, has been learned in the last 50 years and it's amazing how much we don't know.
7:40 - gravity is a force that attracts proportionally between all objects of mass. You have your own personal gravity, it's just your proportional mass is so small that your gravitational effect is inconsequential. Gravity only has one directional exertion, which is towards. There is no up or down, left or right, relative to gravitational force. A person at the south pole of the earth is feeling the same gravitational 'pull' as a person at the north pole, or the equator, or anywhere on the earth's surface. Gravity on mars, or any planet, or any object of mass pulls with equal force, relative to it's mass from any direction. People can't walk to a point and fall off the edge of Mars, because no matter where they walk, Mar's gravitational pull is always pulling them towards it's centre.
James messed up what can be done in an hour between Earth and Mars. It's not 3 messages between each other, it's 3 one-way messages. It's actually a radio signal. The actual time is a little over 4 minutes per way when the planets are close, and the previously mentioned 20 minutes per way, when furthest apart.
millie, every object or astronomical body In space has gravity to some extent, this can be expressed in how many meters per second an object accelerates towards it every second, or to make it easier to comprehend it can be stated in "g"s or "g-force" where 1 g is earth's gravity or 9.8 meters/second². the moon is about 1/6 g and Mars is about 1/3 g. a good way to think of it is if an object weighs 3 lbs on earth it would weigh 1 lbs on Mars (we will use lbs because it's a measure of force instead of density like the kg, 1kg is about 2.2lbs on earth) or if you hear of a fighter jet making a 9g maneuver that same 3lbs object would exhibit 27lbs of force. (sorry if that makes things confusing but that's the best way I know how to explain that.) (fun fact: most wounds/injuries take longer to heal/heal improperly in 0g if they heal at all.)
7:55 Planets aren't flat disks, they're spheres (ish). They're just wayyyyyyy too big for anyone to notice the curve from the ground. The curve is obvious if you look at like a tennis ball because its diameter is like 4-5 inches. The Earth's diameter is 12 742km and the moon's is over 3 800km. Mars is in between, but I forgot what it is. Point is, you won't see the curve from the ground, but you still can't fall off because there is no "edge".
Gravity pulls everything to the center of the planet they're standing on. "Down" is wherever you're being pulled towards (see "which way is down" by Vsauce for a clearer explanation 😅. The reason you don't fall to the center of Earth is because the ground is in the way. Gravity also extends to infinity, but the farther you are from an object (planet, asteroid, moon, etc), the weaker gravity is and by the square of the distance. So if you move 1km away, the gravity will be roughly a million times weaker there.
Now that I say it, it sounds weird, but the maths don't lie... Here's the equation:
F = G(m1*m2)/r^2
where F is the force, G the gravitatonal constant (6.67428x10^-11 m^3 kg^-1 s^-2), m1 is your mass, m2 the mass of the planet, and r the distance between the center of each body.
When space travel first started, they kept the astronauts in quarantine for 7 days to see if they had any affects from the travel. Perhaps that's what you were thinking of. This is a good example of our perceptions and how they color our ideas of life. The entire Universe is 10 Billion times larger than our largest idea of what it could be... not what we THINK it is.
Being small to me gives me a comfort
