Stephen hawking Definition and 97 Threads

Hi users, by the past few months I've gotten really interested in space / quantum mechanics things. I had even read book written by Stephen Hawking 'History of time' which was really interesting but hard to understand as well. So the point it - I want to understand the Rules of Quantum...

I currently just finished reading the updated and illustrated version of "A Brief History of Time" and am almost finished reading "The Universe In A Nutshell" by Stephen Hawking. I really enjoyed both of these books and would like recommendations on other books to read. The only books that...

Seeking clarification on singularity at "genesis" In Stephen Hawking's book, I read that there was no singularity in the beginning of the universe. However, practically every other source I come across seems to be under the impression that there was indeed a singularity before the big bang. I...

Hello folks My name is Mike. I am into Cosmology ever since I was a kid. Throughout the years I strayed away from Cosmology unfortunately but I am very very fond of Cosmology...and thus...call me an amateur Cosmologist :D Anyway... These days couple of questions puzzle me in the...

Good evening everyone, I have a great interest in physics, am sixteen years old, and totally stuck in what I should choose to study when I'm done with school. I live in the netherlands, we have a very different school system then other countries, but basically, I will have to choose a...

In a recent lecture by Stephen Hawking he mentions that our universe started as a singularity. Can this singularity be caused by energy from a Black hole in another space and time? This in turn would mean that an infinite number of universes can be and are created.

So yet we have the Standard Model which tries to explain and unify the 4 fundamental forces or atleast 3 for now since the gravity is not quite well understood in particle physics.So people search for a theory of everything which unifies all forces and yet we didn't found any good theory as...

Hi, I'm at high school at the moment and i have gotten really interested in black holes and the way they work as i have been reading books from Stephen Hawking. So we know that black holes absorb matter and photons by the pull of gravity. And we also know that it emmits radiation. But because...

Ok so, I'm no astrophysicist (I'm only a High School senior, but I have a decent knowledge of Physics and I plan on studying Physics at Purdue University starting in the fall), but let me start... The Big Bang theory says that the universe began as a singularity (or close enough to one if it...

I watched this documentary about an argument involving information loss in a black hole, Stephen Hawking managed to wind everybody up by claiming information was lost and therefore broke existing laws of physics. Its an old recording so it may not be relevant anymore but one part of this...

Hello all . I can not explain good but hope you will understand my purpose . I read in University Oregon's website that universe came from a pure energy in vacuum If we want to say exactly , we can say universe came from Potential energy in vacuum . We know in physics there are some...

Hi, first post on the forum :smile: I am watching this video of a conversation with Stephen Hawking, Carl Sagan and Arthur C. Clarke and about 9 minutes into the film Carl Sagan says: "The galaxys are running away from each other. The further away they are from each other, the faster they are...

I was recently watching "Into the Universe with Stephen Hawkings" (a general video about the universe on Science Channel) when I heard the statement "Just 10 minutes after the Big Bang, the Universe was 1,000s of light years across." How is this possible if nothing can travel faster than light...

hi guys, have you ever read any science book which have stories involving electronics or semiconductor? i mean not a textbook, maybe similar to Brief History of time by Stephen Hawking or Elegant Universe by Brian Greene which is fun to read without advance knowledge in Physics do you...

Im having trouble understanding the gravitational dilation of time concept. I know its states that time go slower on higher gravitational potentials and i know it has to do with light loosing energy (decrease in frequency) as stated in Stephen Hawking's Book "A brief History of Time". How does...

Ok, so everyone in the public knows about Albert einstein, stephen hawking, etc. Yet no one knows any chemists or mathematicians. Are they just bad at marketing themselves, or is it just that physics is more interesting to the public at large since it deals with the grandiose of the universe?

Several articles I've read describing one theory of how everything could have started from nothing. State that all the energy of nothing equals zero as gravity is negative energy. One of those articles was written by Stephen Hawkings. He also stated that quantum fluctations will always exist...

Can Stephen Hawking really claim that there was no time at all before the Big Bang when a black hole can have an outside observer on normal time? And what about other Universes in relation to our Universe? Don't they have a normal time at the time of our Big Bang?

I just finished watching a few Stephen Hawking specials. I watched "Did God create the universe" and the one about black holes. I am by far not even close to knowing anything about Astrophysics, so please forgive my ignorance. I just found the shows interesting and have a few questions...

Hi all, I was studying Stephen Hawking's new book (very good, by the way). He was explainning Feymann's theory, that says a particle travels by all the ways possible to reach a given point. So single particles CAN have interference by themselves. Then he explain why, in the double slit...

I can't wait for this. I suspect it to be only a short appearance, you know how it is. I wonder if he argues with Sheldon http://www.bbc.co.uk/news/entertainment-arts-17337778 I know some of you may hate TBBT as it stereotypes, I guess. But take it as it is.

Do you agree with Stephen Hawking when say "Philosophy is dead" ? *I would have posted it in the philosophy sub-forum , but I thought the material might not meet the guidelines . The content of this thread would fit a general and informal discussion more , I thought. Please move it to any...

After watching Discovery's documentary "Curiosity: Did God Create the Universe?", I can't stop but wondering,... Dr. Hawking claims that there is no time in a black hole. Time stops due to the Gravitational time dilation. The very beginning of the universe is also a black hole. There is no time...

Stephen Hawking on Discovery's "curiosity" I recently watched Stephen Hawking on Discovery's "Curiosity" and found his assertion that a grand designer could not exist based on the logic that there was no time before the big bang troubling.(Due to the fact that the universe before the big bang...

I was watching Stephen Hawking Into the universe and he was talking about time travel. So I got to thinking if time travel into the future is possible then that would mean time isn't a paradox mankind made up and it is physical. Not sure if the formula is even any where right but this is what...

Stephen Hawking gives his take on the "afterlife" Stephen Hawking recently gave his view on death and apparently people are shocked by the answer. http://news.yahoo.com/s/yblog_thelookout/20110516/us_yblog_thelookout/stephen-hawking-says-afterlife-is-a-fairy-story Since so many people...

Awesome! http://www.youtube.com/watch?v=zn7-fVtT16k&feature=channel_video_title See the rest of the series for more awesome!

I have heard a lot of mixed opinions regarding Stephen Hawking and some of his publications. He is widely considered to be a genius and one of the greatest scientists of modern times but most of these opinions come from outside the scientific community. I have also heard that he is rather up...

Article : Hawking contra Philosophy Do you think Stephen Hawking's comments on philosophy ought to be embarrassing to the great physicist?

Here is a question I put in Yahoo Answers: As I said earlier in another thread in this board, I am not a mathematician, here. Just the same I can think and I believe that I can see foolery when I see it and think about it. What do you mathematicians here say about my question...

I've been wanting to read the book lately but before I do, I wish that some can give me a preview of what's ahead. What will be the major/interesting points of the books for someone like me who is just very interested with astrophysics and cosmology but doesn't have a lot of physics...

When i surf internet, i have meet a photo about Stephen Hawking and i have surprised when saw the Stephan Hawking standing. http://bit.ly/9VXk0Y

Recently on my high school graduation an engineer uncle of mine gave me two books by hawking 1)God created the integers 2)On the shoulders of giants I have gone through the books but could not understand how will they be helpful in engineering please guide me how to use them to my benefit

Alternative to "God Created the Integers" ~ Stephen Hawking Hi! I was thinking about buying a decent book covering the history of mathematics (from a fairly technical point of view), and "God Created the Integers" by Stephen Hawking seemed to be the perfect book. However, after having read some...

Hi All, Is Stephen Hawking still able to communicate with the outside world or has he become totally incommunicado? If he is able to communicate, is he still contributing to the field? Thank you, Bob

Why does Stephen Hawking omit all mention Loop Gravity? I have read his popular books from Brief history of time to Universe in a nuthsell to "Stephen Hawking and the Theory of Everything" Stephen Hawking's Universe A Briefer History of Time From what I recall, he absolutely spends...

I'm going to a talk he's giving tonight, and I don't want to offend him somehow. I also don't know if he actually can, practically speaking...

Backreaction blog picked up on the subtitle of Susskind's new book http://th.physik.uni-frankfurt.de/~scherer/Blogging/BookFair/DSCF5540.JPG THE BLACK HOLE WAR: My battle with Stephen Hawking to make the world safe for quantum mechanics. Peter Woit pointed this out. I like having Susskind be...

http://www.sciencedaily.com/releases/2007/02/070227105134.htm Was Hawking wrong? This is only part of the article.

Quoting Stephen Hawking: "... In "Universe in a Nutshell", if in english sounds like that, Hawking said: "universe cannot be infinite because...bla bla...if it would be, every view line will approach to a star, and the sky would appear to us brighter than the sun; obviusly this does not...

Hi, In Hawking's A Brief History of the Universe, he describes a scenario in which it is possible to travel "back" in time. He says, if faster-than-light time travel is possible, it would then be possible to see a race in one location in space, travel to another part of space to relate the...

Stephen Hawking states three possabilities of a Grand Unified Theory: 1.There really is a complete unified theory, which we will someday discover if we are smart enough. 2. There is no ultimate theory of the universe, just an infinite sequence of theories that describe the universe more...

Alan Guth and Stephen Hawking on "Eternal Inflation" It is an interesting topic and Alan Guth had two papers discussing it in 2003, also Hawking had one I found in 2003. might be interesting to check out their recent words on the subject Hawking defined it as follows and then proceded to...

http://abcnews.go.com/wire/US/reuters20040119_134.html For some reason it doesn't seem to add up. The man can talk, if someone were just randomly beating him I don't get why he wouldn't say something. And how could someone be left stranded in the middle of their own garden in an electric...

"The Universe In a Nutshell" by Stephen Hawking I'm reading the book "The Universe In a Nutshell" and I've become confused with a couple of parts... "What do rotating Einstein universes have to do with time travel and time loops? The answer is that they are mathematically equivalent to other...
