Are There Other Universes?

Is the space infinite?

The observable universe is still huge, but it has limits.

That’s because we know the universe isn’t infinitely old — we know the Big Bang occurred some 13.8 billion years ago.

That means that light has had “only” 13.8 billion years to travel..

Do things exist when not observed?

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 old is the earth?

4.543 billion yearsEarth/Age

What makes the universe exist?

Composition. The universe is composed almost completely of dark energy, dark matter, and ordinary matter. Other contents are electromagnetic radiation (estimated to constitute from 0.005% to close to 0.01% of the total mass-energy of the universe) and antimatter.

What universe do we live in?

We live on a planet called Earth that is part of our solar system. But where is our solar system? It’s a small part of the Milky Way Galaxy. A galaxy is a huge collection of gas, dust, and billions of stars and their solar systems.

Who creates God?

Defenders of religion have countered that the question is improper: We ask, “If all things have a creator, then who created God?” Actually, only created things have a creator, so it’s improper to lump God with his creation. God has revealed himself to us in the Bible as having always existed.

Is the earth a part of universe?

Earth orbits one of the hundreds of billions of stars in our galaxy, which in turn is one of hundreds of billions in the observable universe. This apparent insignificance fits with the Copernican principle that our planet is not the center of the cosmos but simply a mediocre member of a mediocre solar system.

Do we live in a multiverse?

This theory states that the universe we live in may not be the only one out there. It proposes the idea that there are, in fact, an infinite number of universes, known as the multiverse.

What is outside the universe?

In our own backyard, the Universe is full of stars. But go more than about 100,000 light years away, and you’ve left the Milky Way behind. Beyond that, there’s a sea of galaxies: perhaps two trillion in total contained in our observable Universe.

What is beyond the multiverse?

Thus it is obvious that even in multiverse scenarios there typically exists “physics beyond the multiverse”, meaning global properties that are realized in any of the parallel universes—at least in the context of the Many Worlds Interpretation.

How many dimensions are there on Earth?

three dimensionsThe 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 Travelling possible?

Time travel to the past is theoretically possible in certain general relativity spacetime geometries that permit traveling faster than the speed of light, such as cosmic strings, transversable wormholes, and Alcubierre drives.

What is the 7th dimension?

In the seventh dimension, you have access to the possible worlds that start with different initial conditions. Whereas in the fifth and sixth, the initial conditions were the same and subsequent actions were different, here, everything is different from the very beginning of time.

Could parallel universes exist?

Parallel universes may or may not exist; the case is unproved. We are going to have to live with that uncertainty. Nothing is wrong with scientifically based philosophical speculation, which is what multiverse proposals are.

Does Marvel have multiple universes?

A multiverse is the collection of alternate universes, with a similar nature and a universal hierarchy. The Marvel Multiverse contains the universe that holds Earth-616, most of the What If? universes, as well as the vast number of the alternate Marvel Universe Earths.

How many universes are there in the multiverse?

And the leading version of string theory predicts a multiverse made of up to 10 to the 500 universes.

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).

Who created the universe?

In his 1988 book, A Brief History of Time, Hawking had seemed to accept the role of God in the creation of the universe. But in the new text, co-written with American physicist Leonard Mlodinow, he said new theories showed a creator is “not necessary”.

What are the 26 dimensions?

The 26 dimensions of Closed Unoriented Bosonic String Theory are interpreted as the 26 dimensions of the traceless Jordan algebra J3(O)o of 3×3 Octonionic matrices, with each of the 3 Octonionic dimenisons of J3(O)o having the following physical interpretation: 4-dimensional physical spacetime plus 4-dimensional …

How many dimensions can humans see?

two dimensionsWe are 3D creatures, living in a 3D world but our eyes can show us only two dimensions. The depth that we all think we can see is merely a trick that our brains have learned; a byproduct of evolution putting our eyes on the front of our faces. To prove this, close one eye and try to play tennis.

How long will universe last?

Assuming that dark energy continues to make the universe expand at an accelerating rate, in about 150 billion years all galaxies outside the Local Supercluster will pass behind the cosmological horizon.
