“There was nothing around before the Big, Big Bang,” Hawking said.

His theory is based on the assumption that the universe has no boundaries

. … The Big Bang theory holds that the universe in retrospective can shrink to the size of an extremely small “subatomic ball” known as the .

What was before the Big Bang?

It's possible that before the Big Bang, the universe was

an infinite stretch of an ultrahot, dense material

, persisting in a steady state until, for some reason, the Big Bang occured. This extra-dense universe may have been governed by quantum mechanics, the physics of the extremely small scale, Carroll said.

What existed before the singularity?

The universal origin story known as the Big Bang postulates that, 13.7 billion years ago, our universe emerged from a singularity — a point of infinite density and gravity — and that before this event,

space and time did not exist

(which means the Big Bang took place at no place and no time).

What is Stephen Hawking's theory of time?

Our subjective sense of time seems to flow in one direction, which is why we remember the past and not the future. Hawking claims that

our brain measures time in a way where disorder increases in the direction of time

– we never observe it working in the opposite direction.

When did time begin?

According to the standard big bang model of cosmology, time began together with the universe in a singularity

approximately 14 billion years ago

.

Who discovered black hole?

Albert Einstein first predicted the existence of black holes in 1916, with his general theory of relativity. The term “black hole” was coined many years later in 1967 by

American astronomer John Wheeler

.

What is Stephen Hawking IQ level?

Name (First/Last) Description IQ (SB) Shakira Singer 140 Sharon Stone Actress 154 Sofia Kovalevskaya Mathematician & writer 170 Stephen W. Hawking Physicist

160

Can u go back in time?

The Short Answer: Although

humans can't hop into a time machine and go back in time

, we do know that clocks on airplanes and satellites travel at a different speed than those on Earth. We all travel in time!

Is there an end to time?



Time is unlikely to end in our lifetime

, but there is a 50% chance that time will end within the next 3.7 billion years,” they say. That's not so long! It means that the end of the time is likely to happen within the lifetime of the Earth and the Sun. … At least, not for another 3.7 billion years.

Does time really exist?

Time is a prime conflict between relativity and quantum mechanics, measured and malleable in relativity while assumed as background (and not an observable) in quantum mechanics. To many physicists, while we experience time as psychologically real,

time is not fundamentally real

.

Does time exist in a black hole?

The only thing is that according to Einstein's General Relativity theory, time slowens when we are under a very strong gravitational field!

A black hole's gravitational field is so strong that time completely stops inside a black hole

!

What is a white black hole?

A black hole is one prediction of Einstein's theory of general relativity. Another is known as a white hole, which is like

a black hole in reverse

: Whereas nothing can escape from a black hole's event horizon, nothing can enter a white hole's event horizon.

Can a wormhole exist?

In the early days of research on black holes, before they even had that name, physicists did not yet know if these bizarre objects existed in the real world. The original idea of a wormhole came from physicists Albert Einstein and Nathan Rosen. …

What was Einstein's IQ?

According to estimates by means of biographical data, Albert Einstein's IQ has been estimated to sit anywhere

between 160 and 180

. That would firmly place the physicist in the genius territory.

What was Albert Einstein's last words?

Albert Einstein's last words

will never be known

. He spoke them in German, but the attending nurse didn't speak German and so couldn't recall what was said. He died in his sleep at a hospital in Princeton, New Jersey on April 18, 1955, leaving the Generalized Theory of Gravitation unsolved.

Who was the cleverest person in the world?

To those who knew of his son,

William James Sidis

was quite possibly the smartest man who ever lived. Born in Boston in 1898, William James Sidis made the headlines in the early 20th century as a child prodigy with an amazing intellect. His IQ was estimated to be 50 to 100 points higher than Albert Einstein's.

How did Hawking speak?

How did Stephen Hawking talk? Hawking previously used his finger to control a computer and voice synthesizer. But once he lost use of his hands, he started depending on

twitching a cheek muscle to communicate

. … Whenever the cursor reached a word or phrase he wished to use, Hawking twitched his cheek muscle to select it.

Why can't we go back to the past?


The Novikov self-consistency principle

, named after Igor Dmitrievich Novikov, states that any actions taken by a time traveler or by an object that travels back in time were part of history all along, and therefore it is impossible for the time traveler to “change” history in any way.

Is Lucy Hawking adopted?

Lucy Hawking Children 1 Parent(s) Stephen Hawking Jane Hawking

When was Stephen Hawking funeral?

Hundreds of people celebrated the life and legacy of Stephen Hawking at the famed cosmologist's funeral Saturday

(March 31)

. Hawking's family invited about 500 people to the ceremony, which took place at Cambridge University's Great St. Mary's Church, according to NPR.

Is it possible to travel to the future?

While

it's not possible (yet)

to travel to the future fast than the rate at which we're doing it now, it is possible to speed up the passage of time. But, it only happens in small increments of time. … According to Einstein's theory of special relativity, the passage of time is relative to an object's speed.

Will we ever be able to travel at the speed of light?

So will it ever be possible for us to travel at light speed? Based on our current understanding of physics and the limits of the natural world, the answer, sadly,

is no

. … So, light-speed travel and faster-than-light travel are physical impossibilities, especially for anything with mass, such as spacecraft and humans.

Will the universe be reborn?

The universe could bounce through its own demise and emerge unscathed. The reigning theory holds that the universe ballooned in size in the first sliver of a second after the big bang in a period called inflation. …

Is time an illusion?

According to theoretical physicist Carlo Rovelli, time is

an illusion

: our naive perception of its flow doesn't correspond to physical reality. … He posits that reality is just a complex network of events onto which we project sequences of past, present and future.

What is the age of Earth?

The age of

4.54 billion years

found for the Solar System and Earth is consistent with current calculations of 11 to 13 billion years for the age of the Milky Way Galaxy (based on the stage of evolution of globular cluster stars) and the age of 10 to 15 billion years for the age of the Universe (based on the recession …

Can time be stopped?

The simple answer is, “

Yes, it is possible to stop time

. All you need to do is travel at light speed.” … Special Relativity pertains specifically to light. The fundamental tenet is that light speed is constant in all inertial reference frames, hence the denotation of “c” in reference to light.

What's in a black hole?

A black hole is an astronomical object with a gravitational pull so strong that nothing, not even light, can escape it. … A stellar-mass black hole forms when a star with

more than 20 solar masses exhausts the nuclear fuel in its core

and collapses under its own weight.

What did Einstein say about wormholes?

Einstein and Rosen found that, theoretically, every black hole is paired with a white hole.

Because the two holes would exist in separate places in space, a tunnel — a wormhole — would bridge the two ends.

Are black holes hot inside?

Black holes are freezing cold on the inside,

but incredibly hot just outside

. The internal temperature of a black hole with the mass of our Sun is around one-millionth of a degree above absolute zero. … When astronomers study black holes, this is the material that they see.

How many dimensions are there?

The world as we know it has

three dimensions of space

—length, width and depth—and one dimension of time. But there's the mind-bending possibility that many more dimensions exist out there. According to string theory, one of the leading physics model of the last half century, the universe operates with 10 dimensions.

Is time the 4th dimension?

According to Einstein , you need to describe where you are not only in three-dimensional space* — length, width and height — but also in time .

Time is the fourth dimension

. So to know where you are, you have to know what time it is.

Can you survive a black hole?

Regardless of the explanation, we do know that

it is highly unlikely that anyone entering a black hole would survive

. Nothing escapes a black hole. Any trip into a black hole would be one way. The gravity is too strong and you could not go back in space and time to return home.

Is wormhole travel possible?

The entrances of general relativity wormholes are hidden behind event horizons, which are one-way barriers in space. That means if you were to enter the wormhole, you

could never leave

, which would defeat the purpose. The other problem is that they are ridiculously unstable.
