From news reports.
The world-famous physicist, who died last Wednesday aged 76, was a co-author to a mathematical paper in which he sought to prove the so-called “multiverse” theory, according to a report by U.K. newspaper The Sunday Times. This theory imagines the existence of many separate universes other than our own.
The research, submitted two weeks ago, sets out the maths needed for a space probe to find experimental evidence for the existence of a “multiverse”. This is the idea that our cosmos is only one of many universes. If such evidence had been found while he was alive, it might have put Hawking in line for the Nobel prize he had desired for so long.
Hawking’s final work — titled “A Smooth Exit From Eternal Inflation” — is being reviewed by a leading scientific journal. In it, he predicted how our universe would eventually fade to darkness as the stars run out of energy.
Hawking, had previously warned that Earth would turn into a giant ball of fire by 2600. Therefore, humans would eventually need to colonize another planet or face extinction, he said.
Hawking claimed at the 2017 Tencent WE Summit in Beijing that “humans will turn the planet into a giant ball of fire by the year 2600”
Overcrowding and energy consumption will render Earth uninhabitable in just a few centuries, Hawking said via video:
Shades of John Ehrlich. Perhaps the proverbial “grain of salt” is in order on Hawking’s Earth prediction.
I greatly admire Steven Hawking’s brilliant mind, vast body of work and constant fight to overcome his physical condition. What he accomplished is truly amazing, almost beyond belief for one so debilitated. BUT: he recently claimed that “time” does not exist! Yet, like all of us, he was born, lived, aged and died! This happened over a 76 year period, not in an instant of time. We claim our Universe is ~13.7 billion years old and the rate of expansion is increasing. Steven was brilliant but obviously didn’t know EVERYTHING! Maybe now that he is with our maker, he does know everything. Thanks for all you have contributed to our understanding of our universe.
Time as a separate dimension may not exist. There may only be matter and momentum, and “time” is a logical construct fitting our perception.
Momentum is: “the quantity of motion of a moving body, measured as a product of its mass and velocity.”
“The velocity of an object is the rate of change of its position with respect to a frame of reference, and is a function of time.”
Thus without time there can be no measure of velocity and thus measure of momentum. The concepts cannot be separated from one another.
As I read this, I get amazed that so many scientific-minded people can laugh at Christianity while stating exactly what the Bible says.
The first sentence of the Good Book, I would think, is known to all educated people. “In the beginning (time), God created the heavens (space) and the earth (matter).” He made them at the same time. He is outside of time, space, and matter.
How could matter come first, with no place to put it?
All that is required to say that the idea of God is possible/reasonable/entertainable is to accept the possibility that there could be something outside of the universe of time/space/matter.
LOL! Probably his best known book is titled ‘A Brief History of Time’.
Time is a human fabricated metric but then again ALL metrics are human concepts. ALL math is a human fabrication and it is the language of science. To deny the existence of time is to deny the existence of science.
No, the point is that time may not be a separate dimension, which implies that it is neither measured nor traveled. Our physics and math are models and tools to facilitate their understanding and exploitation. For example, clocks measure motion, not time, unless you equate momentum with time. Does time exist where there is zero momentum, in stasis? How would you know without an external reference? Another implication is that time travel, forward and reverse, is possible only through rearrangement of all or sufficient (i.e. resolvable) matter and energy within a closed frame of reference.
“A Smooth Exit From Eternal Inflation” Sounds like it could have been written in response to Friedrich Hayek’s warning regarding the end of monetary expansions.
Whilst Hawking was an incredible example of how not to let a disability limit one’s dreams, and a brilliant mathematician, he was also a great example of how being right about one thing doesn’t necessarily make you right about everything. He was a flat out lunatic regarding some of his pronouncements on climate change.
As proof that anyone either critical of or not near worshipful, of Hawkings is not politically correct, I was given a one week, suspension from the World of Warcraft forum, for simply joking, “Can I have his stuff?”
Hawking’s most important contributions to physics occurred before 1975. His theories regarding Black Holes, specifically his 1970 paper, The Second Law of Black Hole Dynamics, garnered Hawking world wide attention. He followed this up in 1973 with his Large Scale Structure of Space-Time. As one scientist noted, the growing interest in Black Holes by the public coincided with Hawking’s theories. By 1979, he was almost at celebrity status. He entered celebrity status after his layman’s book, A Brief History in Time in was published in 1984-85. His close friendship with American scientist, Kip Thorne, also helped in making him a household name in the US.
Hawking continued to dabble to varying degrees in theoretical physics. But, by 1990 his illness coupled with demands on his time, prevented him from doing anymore important work. Like Einstein, he did his most important work at a young age.
“Shades of John Ehrlich.”
Is he related to Paul?
Theory? Isn’t this yet another of a bazillion examples where “hypothesis” should be written?
physical time travel is NOT possible, the entire universe would have to be altered on a physical level……..
neither the past nor future EXIST now,only the present exists.
