Is universe finite or infinite?

The observable universe is finite in that it hasn’t existed forever. It extends 46 billion light years in every direction from us. (While our universe is 13.8 billion years old, the observable universe reaches further since the universe is expanding).

How is the universe finite?

The expanding Universe theory says that the Universe could expand forever [that corresponds to a ‘flat’ Universe]. But it could also be finite, because it could be that the Universe has a very large volume now, but finite, and that that volume will increase, so only in the infinite future will it actually be infinite.

Is the mass of the universe finite?

The geometry may be flat or open, and therefore infinite in possible size (it continues to grow forever), but the amount of mass and time in our Universe is finite.

How is an infinite universe possible?

If the universe is infinite, it has always been infinite. At the Big Bang, it was infinitely dense. Since then it has just been getting less dense as space has expanded. Imagine a large flat rubber sheet with sand placed as closely together as possible on the sheet.

Can universe have infinite mass?

We can consider the universe to be infinite from our point of reference . But we also know that the universe is mainly empty space. However, we do not know (and may never know) the true shape and extent of the universe so we cannot claim that it is truly infinite. Therefore, the mass of the universe is finite.

Does infinite infinite mean possibilities?

If there is a finite probability of something happening (ie. a planet forming around a star, or a galaxy forming), then in an infinite universe there will be an infinite number of that thing. So there would be an infinite number of galaxies and planets in an infinite universe.

How universe is created?

Our universe began with an explosion of space itself – the Big Bang. Starting from extremely high density and temperature, space expanded, the universe cooled, and the simplest elements formed. Gravity gradually drew matter together to form the first stars and the first galaxies.

Who is the father of the universe?

Since the second century, Christian creeds included affirmation of belief in “God the Father (Almighty)”, primarily as his capacity as “Father and creator of the universe”.

Is the universe finite or infinite?

First, it’s still possible the universe is finite. All we know for sure (mostly for sure) is that it’s bigger than we can observe, essentially because the farthest edges of the universe we can see don’t look like edges. The observable universe is still huge, but it has limits.

Is the age of the universe finite?

$\\begingroup$The age of the universe (or multiverse) is not necessarily finite, although logical considerations require that any asymptotically-exponential expansion of space (known as inflation) be balanced between opposite directions, to allow it to be eternal to the past as well as to the future, thereby giving it an infinite age.

Can We expand the universe without the Big Bang model?

We cannot until the Universe is homogeneous, as the Big Bang model also assumes. In particular, the infinite space universe with only finite matter / energy would also violate the Big Bang model, namely it’s Friedman solution – which pose rather strict constrain for Universe size and matter.

Did the Big Bang singularity happen everywhere in the universe?

The Big Bang singularity happened everywhere, in the sense that far back enough in time, the density diverges to infinity at every place. But this is just a particular model–it assumes that the universe if spatially flat and is globally homogeneous and isotropic.
