He certainly inspires me. When I was diagnosed with ALS I too was given 2 years to live.
That was 11 years ago. I won't survive 55 years (I'm 64) but I hope to be around for a while yet
Well done, hope you continue to live a full and happy life x
That's awesome to hear
impossible- i m possible . if someone hasnt told you this. focus on what you can do instead of what you cant do.
You can keep living as long as you are still living. Science shows us that almost anything is possible...
Abbie Thoms I admire people with als what they go through and yet they still plod on regardless there blave strong and great will power to survive may be hard but they never give up I wish I could have gave steven hawkings a hug he has great willpower,
If anyone tries to argue against designing a world to include all people, especially those with disabilities, Steven Hawking is a great example of what our universe stands to lose.
Great words Calcputer - couldn't agree more
Even thou I believe in the right to choose abortion or not I sometimes think similarly that what great minds and contributors to society that we may be loosing. Another MLK, an Einstein, Hawking and even a Marilyn Monroe and on the darker side, a Manson or Dahmer.

Joe you may not be a scientist but you surely are a great and smart science communicator!!! Once again a nice video :D
Anyone who uses the scientific method can be a scientist ! Science is a way of thinking, it's not a degree ;) .
I appreciate that. :)
Hilary Action.
indeed Joe, you are a scientist, so are your viewers, we're all learning from your lectures/videos. don't sell yourself short
Albe Van Hanoy don’t be so absurd
A true scientist should be happy about being proven wrong. It's the whole point of science. Hawking was a true scientist.
You are absolutely right
Also great username
You only learn one way to make something work if you get it right. If you get something wrong, then the future has less work to do. Being wrong can teach you more than being right.
Not too long ago I got called several different kinds of stupid for suggesting that a scientist should be happy about being wrong, and in fact should be thinking about ways to disprove what he thinks is right. A scientist who absolutely must be right (or he'll lose his funding for example) will be in danger of being right at any cost. I just don't see what's so hard to understand about this.
BTW, Einstein was also wrong many times just as basically every genius scientist, it is fine.
@@flare9757 The golfer, Bobby Jones, claimed he never learned anything on a good day.
Okay sure I'm very late, but Joe! You forgot the most important thing about Stephen Hawking by far!
He is the only person to have played as himself on an episode of Star Trek!
I was actually just thinking of that
He played a hologram A.I. of himself not exactly the same thing.
@@dewayneweaver2744 I'm very unfamiliar with Star Trek, but if the A.I. mimicked him exactly, then, especially considering that he couldn't move his physical body anyway, it _could_ be considered to be him actually playing himslef.
And on The Simpsons and The Big Bang Theory.
@@upperleftcoastchelseafan7718 That would be a resounding 'No'. Adam West also played himself on the Big Bang Theory, and probably on the Simpsons as well.
Hawking occasionally took those bets when he knew he was probably wrong. He just wanted to see it settled properly and not just presumed.
I finally discovered this channel, and let me tell you, during this crisis it's been a lifesaver for me, emotionally. This was an *amazing* tribute to an otherworldly intellect known as Stephen Hawking. Well done.
Of course Hawking's biggest contribution was not to science but to people. His story inspired all of us. He was (still is) the most well known scientist of today. He lived a full happy life in spite of his illness.
I respect Steven Hawking but his stand that God does not exist when his own space time thereoms prove there exists a transcendent causal agent shows him to be a fool leading others to follow him to hell.
@@tedbates1236 what😂
i wouldnt say most well known, most likely albert einstein.
@@tedbates1236 Isn't it funny how one of his books was called "The Grand Design"?
Sort of implies a designer now doesn't it. The funny thing... People thing he was smart LOL.
It’s one thing for you people to have different beliefs than him, it’s a complete other thing to say he’s leading people to hell, or isn’t smart.
Hawkins changed the world from a wheelchair and paralyzed, yet everyday we see people complaining about trivial things. Really puts our lives in perspective. Great video Joe!
lol how did he change anything?
@@rachelmatthew6771 you don't have to move mountains to change the world, but you can reveal where those mountains originally came from!
@@ronschlorff7089 lol sure! But it is almost impossible to tell where the mountain came from. We all can spew some BS but that doesn't mean it is the truth. Space is very huge and we still havent been able to move past mars. I agree we can come up with theories/hypothesis but those will be unproven until we have fixed proof.
@@rachelmatthew6771 Not getting past Mars? So all the USA's deep space probes to the outer planets including Pluto didn't exist? And the 2 Voyagers which left the solar system are a joke to you. Based on your comments, yeah, something sure is a Joke!
You're forgetting he was also absolutely fucking loaded and had a maid and the excuse... the never ending excuse... He was also groomed since birth to be brilliant and he was obedient to it. He also didn't exactly fathom truths, he fathomed hard to argue guesses with knowledge the poor and able bodied can't afford to memorize and toy with guesses on. Do you know what a trickshot is? Ball and a cup? It was literally that with words. He created nothing. He found no laws. He did not change the world. He wasn't an inventor. He was just a famous person. Miley Cyrus is famous too. He did nothing to help humanity. Change the world my ass.
Stephen's greatest contribution is a testament to the human spirit
Stephen Hawking abused children on the child abuse islands of Jeffrey Epstein. It came out in unsealed documents with pretrial judgments of the on-going Ghislaine Maxwell prosecution.
His sense of humor, it opened his brilliance to the masses
People say good comedy is about timing but Hawking was that funny even with little control over the timing of his dialogue he could still crack great jokes and respond quickly with witty remarks :)
His brilliance would have been noted with or without a sence of humor man.
Though it didnt hurt, that's for sure.

Michio Kaku. Brilliant and the best scientist/science communicator I've ever heard. Also, they should quote you "Even if he lost science won. And that's all that mattered." R.I.P. Stephen Hawking
volatile0701 Michio Kaku is pretty smart and did work on string theory, but I would say he’s not much different from NDGT: a much better science communicator than a scientist.
Jason Martin that's a very valid point. I have to admit that I have a weak spot for MK and for some reason NDGT has always rubbed me wrong. So they are both better communicators but I believe in the scientist department I give the nod to Kaku. But I'm also a supporter of ST so there ya go haha.
To be honest, for a long time I ned Kaku only as "that smart sounding guy from all the documentaries", didn't even realize he was such a well-regarded scientist.
Says a lot about his skills at communicating knowledge while staying extremely relateable.
volatile0701 I'm astonished if people can find other people like kaku or Tyson rubbed them wrong... It doesn't make sense, how, why, what?
a couple of months prior to Mr.Hawking's announcement of "why he fears AI" , Kaku had announced a facebook q&a.
i was looking forward to it, and when it started i asked what he thinks would happen if we dropped some robots on a planet with only one command; to reproduce and better themselves when possible.
never got a response.
that rubbed me wrong!
Good show, old chap, and may you rest in peace, with the knowledge that you helped make the world a better informed place, the most noble life that can be led.
Also, Joe have you ever done a video about Carl Sagan? I often feel like Carl Sagan awareness is tragically fading these days. Everyone knows about Cosmos and the Voyager plaque, but he did a lot of other great things too, and in my opinion he was also one of the best science communicators of modern history, alongside people like Stephen Hawking.
It seems unfair to me that Carl died so young. I think the world would have been markedly improved if he had been here to help us understand, and to spark curiosity and wonder in young minds. His legacy lives through cosmos, but imagine if he had a TH-cam channel. That's why I love channels like this one, because it's nice to see that the spirit of people like Carl and Stephen lives on, as long as there are those with ears to hear, and minds to wonder.
Austin Bellar qerrqrteieeteeeqeeieiieiieeeieiiqieeiieiiieieeieeeeeeiiieqiieieiiieqiieieieier
yeah get tell us about carl!
Also Richard Feynman for the same reasons. His lectures are fantastic even if you don't know anything or care about physics.
Yaasssss! Carl Sagan was absolutely brilliant. Now, I'm not saying that he was even better at explaining science than Stephen Hawking, but he was.
Whole generations are growing up without "billions and billions." :(
His greatest accomplishment was not letting something like ALS every slow him down or dampen his genius. A true intellectual hero.
Truth well said.
"If you can't explain it simply, you don't understand it well enough." - Albert Einstein
I don't really believe in miracles. But Stephen was definitely one.

His biggest contribution to mankind was that he never gave up and was a perfect role model for people who got hit hard in live. Not matter what,he did what he loved and mastered it
Thanks for making this video Joe. This subject hits home for me as my Mother has ALS and she is in her 6th year. When I found out Hawking passed away, I hurt and cried. He was one of the examples to look up to for not only surviving as long as he did but also for proving that when you're told your life is over you can truly continue to do great things. It matters that you do everything to the best of your abilities even in the face of death otherwise you're not living.
Wow! What a fabulous tribute to an amazing individual. A great man with a super sense of humour. Never took himself to seriously. The right way to be imho. As someone said Joe, you may not be a scientist but you make the subject fun, enjoyable but most of all understandable. Thank you sir. Definitely a good show old chap.....you know we Brits don’t say that.....right? Keep up the fabulous work
Hehe, I know I don’t use that term correctly but it just became a thing.

Hope Joe's clone makes a comeback👀
Man, Stephen Hawking was incredible, he beat the odds, was smart and funny, he had it all😍 I always wished to meet him but just knowing both of us lived in the same time frame is awesome.
He had it all... except a working body.
Joe Scott ba dum tss😅
He was apparently a huge, while keeping it clean... a huge jerk lol
This video was touching. Thanks man.
Lovely video! Indeed, good show ol'chap :) I think more people like him will emerge in the next decades. He has definitely inspired many generations of scientists and communicators
I couldn't have put it better myself. :))
I agree that the time travelling party does not prove anything. But it was a humorous show. What a great memorial video, Joe! He was a force! Of that I think all can agree.
It proved that time travelers either didn't know about the party, didn't want to come to the party, or couldn't come to the party (because of reasons, including that time travel doesn't work at all).
Helge Moulding
I tend to believe that a hypothesis that "proves" every possible outcome proves nothing. ;-) It proves that time travel is possible or it's not. You could even conceive that the invitations got lost during the time that it took to figure out time travel and then to build a workable model. Were those to whom he invited even still alive? Had their heirs and assignees simply tossed the invitations? Who knows. I still think it was humorous, though.
It was more a thought experiment in practice, not meant as evidence.
There would be strict laws on time travel, what would probably be allowed is only watching the past with something like google earth. Interacting and walking around in the past would be too risky.
Or maybe they could reach for the party at the exact time coordinates, but the Earth wasn't at the expected place.
as one of your avid followers, when you said "say it with me" i automatically respond to say "good show, old chap" without thinking, wow. keep making vids.
If I didn't, people would have made a stink about it. :)
Brilliant video. Thanks. See you yesterday Steve. Still called Motor Nurone Disease here in England.
But how confident can we be in such a diagnosis? May SH didn't have ALS. Is there any absolute test?
Some people wonder why he never won a Nobel prize. In truth, Hawking has made predictions that have yet to be observed and some predictions take a long time to observe (ask Peter Higgs). Unfortunately his death means he never will get a Nobel prize :(
Anoiny posthumous nobel prizes aren’t ever given- or else Rosalind Franklin would have received one for her contribution to the model of DNA
Aside from that, the nature of Hawking's life, it's style and constraints, made him a theorizer rather than an experimenter - recall that Einstein did not win a Nobel Prize for any of his four relativity papers, because he did not conduct any of the experiments that validated his theoretical work.
When I was younger and in another universe, many mysteries were answered from watching Johnny Sokko and his flying robot.
Thank You Stephen..peace from Texas
Thank you Joe for perhaps the best resume of Stephen Hawking that I’ve ever seen or heard. I’m a new follower of your channel and have been impressed with the simple way you deliver an enormous amount of information. Sometimes I have to go back two or three times to catch every word you said because there was too much packed into that particular phrase. The episode on survivability on Mars was particularly poignant. We tend to think the hardest part is getting there when in fact it’s staying there. Thanks!
Professor Hawking was my mentor. I got my perspective from him. Now, my field is Biochemistry but I couldn't bring myself to respect someone as much as Stephen Hawking in the field of science.
We need to get hold of his chair. I think it knows more than we think.
it all started with a big bang
*BANG*
Happy birthbay
Thanks😉
I had the great honor to meet Dr. Hawking in a private gathering before his public speech at De Anza College (Cupertino, California) Jan 21, 2000. In fact I have a prized photo taken of us together. Dr. Hawking was witty when in the introduction they mentioned that Dr. Hawking and Sir Issac Newton held the same chair at Cambridge, Dr. Hawking said (via his speech synthesizer) "At least his chair wasn't electric." I was sad to hear his passing and will forever have that memory. Thanks for posting this video, a great salute to a great man.
Regarding Dr. Hawking's time-travel party: Instead of throwing a party, I have always thought that Dr. Hawking and other physicists should build and maintain a computer solely for the purpose of receiving data from the future.
Rules: Any message received should include an atomic timestamp encoded within the message, name(s) of the senders, location of origin along with a simple message that will not create any sort of butterfly effect that would prevent the message from being sent in the first place. Moreover, the individuals maintaining that computer should agree to not contact that sender until at least one day AFTER the message is actually sent.
I suspect that the easiest way to prove "time-travel" with be to send something with near-zero mass -- like data. The computer can always be modified with various components publicized so that interested scientists could know how to "contact" the computer at a past moment in time.
After "first contact," the rules for information would be altered to include a reverse "Prime Directive" -- meaning that any such data can be used for the betterment of the recipients place in time going forward. In other words, advances in science could be sent back and would be used regardless of how the future might change. Moreover, if someone sent back information pertaining to a dark event in (future) history, steps would be taken to prevent the event.
I think that a symbolic prize should be offered (i.e., the Time Travel Pioneer Prize) that would name such individuals as the first known time-travelers.
~~~
As for science communicators: I'll miss Dr. Hawking like others before my time missed people like Dr. Carl Sagan or, of course, Dr. Einstein. I'm not too keen on Neil de Grasse Tyson. He is certainly a bright man; however, his fame is staked on little more than his degree (there are many, many PhDs in Physics who are more accomplished). Tyson just isn't accomplished enough to lend weight to his lessons (no matter how good they might be) and appears to be more enamored with his own status as a celebrity than actual scientific prowess. In fact, I'd argue that Joe Scott is a better science communicator than Dr. Tyson or guys Bill Nye.
I can't think of a scientist off hand who could succeed . I suppose that the fact that this question exists is evidence that there are no viable candidates. There aren't many scientists widely known by society on the basis of their scientific achievement. Einstein wasn't publicly famous until he was so accomplished in physics. The same was true of Sagan and Hawking.
Dr. Kip Thorne (mentioned in the video) is an amazing physicist -- a friend of both Hawking and Sagan. In fact, he is one of the most accomplished physicists who is generally respected by nearly all leading physicists today. However, his lectures and talks are generally a bit cerebral for the general public. He is also older than Stephen Hawking and isn't too far from outliving the current life expectancy for males. He was a co-recipient of the 2017 Nobel Prize in Physics for work with the detection of gravitational waves.
I can't really think of any other accomplished physicists at this point in time (which is sad). However, like this video states, a science communicator doesn't necessarily have to be a highly accomplished scientist. Individuals who weren't nearly as accomplished obviously inspired people like Einstein, Hawking and Sagan. Perhaps the "next Stephen Hawking" is a young subscriber to Answers with Joe. Maybe they'll be the first to send a message to the past and let us know.
Leonard Susskind
In the future, guest receives invite. "Oh shucks! It's over with! I missed it!". Tossed invite! 😋
We were lucky to have him for the time that we did.
finally someone that understands, i have been explaining to coworkers that he had a amazingly long life and that he was ok with death.
When visiting my home town of London, I sometimes visit Westminster Abbey to pay my respects to many of the people interred there. It’s humbling to be able to stand just a few feet away from some of the greatest people in history. Sir Isaac Newton in particular was one I never missed dropping by. However, this last visit to Newton was a shocker. As I turned away to leave Newton, I glanced down and saw Stephen Hawking’s grave, I had completely forgotten that he was interred there and I immediately started weeping uncontrollably like a young child. Although I understood little of his science he clearly meant more to me than I had realized.
As a SpEd teacher, and as a software engineer, i looked into the talking devices that HE created for himself and gave to the world. The technical and AI quality of the devices would NEVER reach usability without his stubborn willpower to be able to talk no matter what. That legacy is life changing, and i feel privileged to have seen and used and witnessed the miracle.
Just discovered your channel. Love it...
Thanks!
Welcome to the club, Mark! Joe's content is always on point :)
Great video Mr Scott! Hawking was an amazing individual, may he RIP floating in the vastness.

Hi Joe. Great video!
As you said, Stephen Hawking was born on the 300th anniversary of the death of Galileo and died on March 14th, which was Einstein's birthday.
I’m not sure if it was mentioned in any of the comments but March 14th is also known as “Pi Day” 3/14 ~ 3.14 (the math symbol holiday).
A great math concept is simple, beautiful and complex all at the same time. Pi is one of those concepts and I would describe Hawking and Einstein the same way.
I never knew about that little story at the beginning of your video. That's pure awesomeness
Maybe they showed up but all agree to keep it a secret
Hello Joe, please make some more videos on the work of Mr Hawking.
thanks joe you saved my time and efforts so heres a subscribe for u
This is heartbreaking an incredible man has left the earth to live in the stars. Wish there were more people like him
Hope he has found all of the unanswered answers now. Rest in Peace Stephen
To me, what would be better than 'heaven' would be the ability to explore the universe and find out that the questions are infinite!
stephen was possibly the best physicist ever
I regret I never really paid a lot of attention to him.
rest in peace Stephen, rest in peace
I have a few of his books around the house and now I can. Not. Find them. Driving me crazy.
not , , , quite .he was embarrased by this hype when among his peers.for the less than 20 yrs he was productive he was one of the dozen or so physicists at the cutting edge,and was just an average member of that group. that said,,,,,,,,,,,,,,,being ranked 8 or 9 in the world for 15 years in theoretical physics is,,,,,,,,,,an incredibly impressive feat!!!!! , then you consider he did it while in absolute medical misery.
It boggles my mind to ponder what he may have accomplished had he not been afflicted with such a horrible disease.
Stephen himself said that his condition gave him lots of time to study and gain knowledge. Its possible he would have accomplished less without ALS.
Robert Woko dang sounds very intriguing do you have the list of the others? we need to learn from them before thEy die (morbid yes)
Can't believe it's taken me so long to watch this one. Great vid Joe.
Joe I've just watched this 18 months after you posted it, enough time for emotion and talk to settle down after Hawkings death - yet I still find your video moving, eloquent and very well pitched. Nicely done, sir!
I know this is heresy, but I've always thought that for each black hole there is another universe inflating on the over side. In this way, energy, mass, time, and information are conserved.
An interesting hypothesis! How would that reconcile with Hawking radiation though, wasn't that his answer to that problem?
6:16 Woah! Mind blown! If you go back close enough to the Big Bang time gets taken over by space. So if there is no time, the universe had no beginning. It's like asking what is north of the North Pole--the question doesn't make sense. When did the universe begin? There was no time, so the question doesn't make sense. Woah.
His legacy is the people he inspired to become Scientist .......a priceless contribution......he increased our knowledge of the Universe with his own research whilst increasing our pool of Scientists through inspiration & at the same time making the knowledge accessible to the general public & showing them the importance of Science.
I had the honor of meeting him he was such a great man he was inspiration to me and I will always remember him for being a great man. RIP Steven Hawking.
Wow
Good show old chap, rip Stephen Hawking
I really would like to honour you for paying such a tribute to one of greatest scientist of era ......Late Stephen Hawking .......This video was really very informative ......
Stephen Hawking was loved by his students and had a tremendous sense of humour. I read his book" A short History of Time" during a flight from Sydney Australia to Vancouver in about 1995 and was unable to put the book down until I had finished it. I have always regarded him as a giant of science.
Matt O'Dowd host of PBS Spacetime is great =D
"Good Show ol' Chap"
It's been a year already. Time flies, then gets compressed, then become even more confusing to me. Nice work my friend.
Thanks for your perspective on Dr. Hawking. I'm a biochemist, not a physicist, but I think one of his greatest contributions was the way he inspired people at a personal level to help him live and communicate and the way he inspired scientists and non-scientists to be awed by the universe we live in. In a world full of imaginary super heroes, it is nice to recognize and appreciate the real ones.
Good show ol' chap.
For a long time I thought that just as Einstein was the smartest physicist alive in his day, Stephen Hawking was the smartest in ours. I then heard some world-class physicists saying that SH was smart, top-10 smart, but by no means the _smartest_ . Edward Witten (the guy who unified string theory into M-theory) was generally regarded as the most brilliant physicist around. Witten is perfectly healthy, has an odd affect, speaks with bit of a lisp, is not good in an interview, and (as far as I know) hasn't written any books--so few people outside of the physics world know who he is.
I read _A Brief History of Time_ and, honestly, was disappointed. Don't get me wrong, it was a fine book, but I've read better explanations of these subjects by other authors: Carl Sagan, Brian Greene, and Martin Rees come to mind. _ABHoT_ won all kinds of awards and had so much buzz that I had expected something spectacular and was disappointed.
I'm convinced that Hawking was so famous because of his disease, that he was wheelchair-bound, and had to talk with a computer voice. He deserves all the credit in the world for his accomplishments despite his disease, but I think the contention that he was the *best physicist in the world* and the *best science explainer in the world* is overblown just because he was a celebrity.
ChrisBrengel Both Einstein and Hawking are frauds. Look into it.
We are fortunate to have lived during the time of this great man's contributions to science. We are also very fortunate to live during a time when medical science has advanced enough to allow this man to continue long enough to provide us with all these insights into science.
I love it when you mention patrons with funny names!
"Infinite smallness" should probably have been "Zero volume" Smallness isn't really a concept you can quantify.
The second that came out of my mouth I knew it wasn't right. :)
Try "Infinitesimal" or "Infinitesimally small".
i didnt even know he passed away, #1 thing comes to mind is why wasn't it all over the front newspapers?
I don't know... It was all over the internet.
Omar Aziz same
Further proof newspapers are dead
They're too busy pushing russian conspiracies to print newsworthy stories.
they are no longer "news" papers.... they are partisan rags that don't deserve the name journals or those that work for them, journalists... there are more people who are on the internet that deserve those titles, like Joe... Thanks Joe for all the great news you broadcast to the World... Good show young lad !! yeah, at 200,000 years old, I can say that :D
"Universe in a Nutshell" was huge for me. I found it in the library in my hometown, and it completely blew my mind. I never thought I'd understand cosmology like that until I read that book. On the flip side, it made me completely underestimate how difficult some of these subjects are, since he was so good at communicating them. I bought a string theory book not long after, thinking I could just plow through it like Hawking's book, and holy shit was I wrong. I really think his ability to explain these topics to the layperson cannot be understated.
Steven hawking’s was an amazing man! How fortunate we were to have his genius inspire us!
R.I.P. Stephen Hawking 1942-2018
33rd yesssssss
Excellent job as always Joe. I cannot wait to read his most recent paper published. The man never stopped working. Amazing
RIP Mr. Hawking. Sean Caroll is the man. And "Good show, old chap." is one of your catch phrases that I like. Keep the good vidz coming
If you had a time machine, why would you bother visiting an ancient professor from the past when you can be anywhere?
Realistically, he hadn't even figured out time travel yet, so what could he possibly teach you?
Lovely man though, he had a way to explain the complex that few people could even come close to. I think that's what I liked about him the most.
Answer: the same as to many flawed hypotheses around the Fermi Paradox - it is likely one specific time traveller might not want to go back to Hawking's party, but it is highly unlikely to say that about all of them. Unless time travel backwards (or at least before the point of the invention of the time machine) is impossible.
If you had a time machine, you could go everywhere you wanted for as long as you wanted.
Saurav Raj: Where do you take that from? It's a fictional device. If there will ever be a real counterpart, it very, very likely will have limitations.
Because if you look away from all the paradoxes rendering backward timetravel next to impossible, you would be able to exist in multiple time periods. Techically 300 versions of yourself could enter his party at the same time, if you was just to go back and fourth to the same date 300 times. This create a paradox tho as then you would never appear alone and never appear with 300 copies similtaniously, rendering it both possible and impossible at the same time. Even tho you travelled back to the age of the dinosaur, you could still always travel back to that party whenever you wanted. Afterall, you have all the time in the world.
What I'd take from it is this:
1) Time travel isn't possible,
2) Stephen Hawking's invitation will be forgotten before it's invented,
3) Humanity will die out before it's invented,
4) If any form of time travel is possible, it might only be possible to observe the past and not interact with it,
5) Time travel is possible but it somehow spawns a new reality, and the time traveller would be present only in this new reality.
6) There might be strict rules set that will prevent time travellers from interacting with the past, especially for mundane reasons such as a professor's joke.
7) Time travellers have no reason to do that.
Michio Kaku, geneus and great communicator

Thanks Joe for doing this tribute to Prof. S Hawking, he was a true scientific heavyweight of our time and even more amazing considering the huge handicap that he battled, in the form of motor neuron disease. Not only was he ground breaking in his scientific work, but as you rightly pointed out, was a firm believer in making that knowledge available in a form we could all understand and marvel at.
It's a very rare skill for sure.
Stephen Hawking was a gift to humanity. Our understanding of the Universe would not be as advanced as it is now were it not for his contributions to science. R.I.P
He missed it with his "theory of everything"...
Perhaps his greatest accomplishment will be his method for detecting parallel universes which was almost ready to publish. A sad and happy ending in the same time, depending on which universe you live in.
Well, I'm looking forward to further info on that in the coming years.
You should have more subs :( ....
My name is Many Others and im thrilled that I got a mention in this video, thanks Joe
As busy as you are, Joe, just wanted to say I appreciate you taking the time to make a Hawking video after all. Yay!
Felt like the right thing to do.
Sean Carroll is a good science communicator, but nowhere near the mental ability of Hawking. Susskind himself is pretty good at both, but I guess he's kinda old now. Witten is probably the smartest physicist alive today, but he's not a good science communicator.
It's already been essentially proven that if time travel is possible, it is only possible to travel back to the point when the tine machine was invented and not before. It is highly unlikely that any other form of time travel to the past is possible. It is also unlikely that this form of time travel is possible, but there is less evidence to prove that it is impossible.
It is highly unlikely that any pro scientist will ever prove anything time-travel-related rigorously; 'cuz you know, CTC = time-travel and we're done, r8?
I agree with you there.
Correct me if I'm wrong, but I thought that traverseable closed timelike curves are not excluded by General Relativity, but they aren't guaranteed either. There are solutions that form Einstein-Rosen bridges and other CTCs, but that doesn't mean that anything like that can actually be created and traversed without violating some other law of nature. Most things that are possible in general relativity, even things like black holes that Einstein himself didn't think were real early on, were eventually found. But not everything. Tachyons are a notable example of something that most physicists think is not real even though it could theoretically exist within Einstein's theory.
"not excluded [...] but they aren't guaranteed either" Oh yes, they exist - and even if we knew of only one example, it could still be a huge problem; in doing research for a time-travel video, I compiled a shitload of solutions which have them, and those are just 'textbook cases', it's a really general behavior
"without violating some other law of nature" I would call 'energy conservation' a 'law of nature', but an 'energy condition defined only to make proving theorems easier' - not so much
"Tachyons [...] exist within Einstein's theory" Actually tachyons (and for that matter particles with continuous spin) are not a prediction of Einstein's, but Wigner's - and in the context of SR; can't dream what 'tachyons' would look like in GR, specially considering we are nowhere close to a half-decent theory of Hawking/Unruh rads
Iago Silva Interesting. I'm afraid you've gone a couple steps past my level of understanding. Hopefully on of the great science communicators I watch on youtube, like PBS Spacetime or Looking Glass Universe will cover some of those topics. (More likely the former, as his expertise is in relativity. The latter is less well known, but she does high level quantum stuff better than anybody and I highly recommend her channel. She doesn't post often because she's busy with her Ph.D, but she says she will start posting more soon.)
This is by far the best tribute I've seen so far. Good show, old chap.
I'm a little late..just wanted to show my respect to Dr.Hawking and Joe.
Great job indeed.
Greetings from Croatia!
Mate...I collapsed when I first knew about his departure. I dreamed of meeting him since age 8. And now it can never be fulfilled. He inspired me into working to become the scientist I aspire to be and I really love this.
Joe, as always you make science, and science history, understandable for dummies like myself.
One of my favorites, and life changing, quotes was from him.
“One of the basic rules of the universe is that nothing is perfect. Perfection simply doesn't exist..... Without imperfection, neither you nor I would exist.”
Hawking is my hero. He had a lot going against him but he didn't let that stop him. He accomplished so much and he wanted the people to understand science, knowing they could not be able to comprehend the launguage of mathematics used to understand our world.. he found an easily digestible way to convey what he knew to anyone willing to learn. I remember reading his books as a young boy being filled with wonder and excitement. He, like many scientist, gave me a thirst for truth and understanding. But it is he who I think of when I hear myself setting limitations, or when something goes wrong, or something prevents me from doing what I love. I think of him and I realize that I can do anything if I want it enough.
Where I came from, every kid who loves physics idolises Albert Einstein, Richard Feynman and Stephen Hawking.
Possibly the most amazing thing about Stephen Hawking was the fact he lived to the age of 76.
I got goosebumps near the end.
Since i was an annoying kid (well im still one lol) i was interested into the universe and everything in it. I remember sitting in front on my tv, watching the same documentations over and over again. For hours.
I wanted to to sth with the universe when i grow up. But as i grew up, i saw that im an absolute 0 in maths and physics. So that dream of mine went down the drain.
Im studying law now, hopefully i'll become a good lawyer...but after watching this video i think i might study cosmology afterwards. The topic just interests me and i could talk about it for hours. Im glad i watched this video.
Thank you, buddy
Max Tegmark I think is one of the more brilliant Science Communicators out there too. It's always a treat to hear him talk about the universe and reality.
I have now binge watched numerous videos of yours and I am very impressed! Great content and superb delivery of the subject! Keep up the good work!!
Thank you for this tribute, and for delaying your planed video. It was so heartfelt and brilliant and just like you always do. I really truly enjoyed watching this. What a wonderful mind, and such an amazing contribution to us all. And what a silly guy. Love it all!! I was hoping to hear from your channel, on his passing.
II consider you, David Tong, Ed Witten, and Sean Carroll the most interesting and informative people on the Internet. My brain is a better place for you guys' work! Thanks!
I don't think I apprecated Hawking until this video, thanks!
I love the fact that you live and present content in and about reality.
