Question: Can The Universe Come From Nothing?

How did the universe come from nothing?

Quantum mechanics tells us that “nothing” is inherently unstable, so the initial leap from nothing to something may have been inevitable.

Then the resulting tiny bubble of space-time could have burgeoned into a massive, busy universe, thanks to inflation..

Can the Universe Create Itself?

“Because there is a law such as gravity, the universe can and will create itself from nothing. Spontaneous creation is the reason there is something rather than nothing, why the universe exists, why we exist,” Hawking writes. “It is not necessary to invoke God to light the blue touch paper and set the universe going.”

Does the universe have an end?

The end result is unknown; a simple estimation would have all the matter and space-time in the universe collapse into a dimensionless singularity back into how the universe started with the Big Bang, but at these scales unknown quantum effects need to be considered (see Quantum gravity).

Is nothingness possible?

There is no such thing as nothingness, and zero does not exist.

How is nothing created?

Vilenkin’s calculations show that a universe created from nothing is likely to be tiny, indeed — far, far smaller than, say, a proton. … Although a universe, in Vilenkin’s scheme, can come from nothing in the sense of there being no space, time or matter, something is in place beforehand — namely the laws of physics.

Does the universe have zero energy?

In the case of a universe that is approximately uniform in space, one can show that this negative gravitational energy exactly cancels the positive energy represented by the matter. So the total energy of the universe is zero.”

What was before the universe?

The initial singularity is a gravitational singularity predicted by general relativity to have existed before the Big Bang and thought to have contained all the energy and spacetime of the Universe.

Do things exist when not observed?

The idealist philosopher George Berkeley argued that physical objects do not exist independently of the mind that perceives them. An item truly exists only as long as it is observed; otherwise, it is not only meaningless but simply nonexistent. The observer and the observed are one.

How long will the universe live?

The stars themselves, however, will continue to burn for a long time. The Universe is already 14 billion years old, but the longest-lived stars today — the low-mass red dwarfs — will continue burning through their fuel extremely slowly: for perhaps more than 100 trillion years.

Do we live in false vacuums?

The possibility that we are living in a false vacuum has never been a cheering one to contemplate. Vacuum decay is the ultimate ecological catastrophe; in a new vacuum there are new constants of nature; after vacuum decay, not only is life as we know it impossible, so is chemistry as we know it.

How much positive energy is in the universe?

The zero-energy universe hypothesis proposes that the total amount of energy in the universe is exactly zero: its amount of positive energy in the form of matter is exactly canceled out by its negative energy in the form of gravity.

What did God not create?

God no longer has any place in theories on the creation of the Universe due to a series of developments in physics, British scientist Stephen Hawking, seen here, has said in extracts published from a new book.
