Is space infinite or finite?

Is space infinite or finite?

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).

Who proposed the idea of the infinite universe?

Such a universe does not have so-called spatial curvature; that is to say that it is ‘flat’ or Euclidean. A static infinite universe was first proposed by English astronomer Thomas Digges (1546–1595).

Why do we think the universe is infinite?

If the universe is perfectly geometrically flat, then it can be infinite. If it’s curved, like Earth’s surface, then it has finite volume. Current observations and measurements of the curvature of the universe indicate that it is almost perfectly flat. You might think this means the universe is infinite.

Is it possible that space is infinite?

Tanya Hill, Astronomer – yes 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).

What is infinite universe?

To be clear, a truly infinite universe means that anything that is not impossible (no matter how obscure) will happen, must happen and must happen, weirdly, an infinite number of times.

What is infinity in space?

Infinity is just as the term indicates, boundless, borderless. Infinite space is boundless, borderless and eternal. The “Macro-cosmos” is boundless, borderless and eternal a combination of space and energy in its multiple forms. Cite.

Is the universe finite or infinite?

Two possiblities exist: either the Universe is finite and has a size, or it’s infinite and goes on forever. Both possibilities have mind-bending implications. In another episode of Guide to Space, we talked: “how big is our Universe”. Then I said it all depends on whether the Universe is finite or infinite.

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.

Is the universe flat or curved?

Measurements taken by satellites have pointed to the universe having a flat geometry. In a flat universe, two light beams shot side by side through space will stay parallel forever, and will never cross or drift apart. In this sense, we can still think of a cylinder or torus (donut) shaped universe as being “flat”.

How would you measure the size of the universe?

And if the Universe is finite, well, it’s finite. You could measure its size with a really long ruler. You could also follow up statements like that with all kinds of crass shenanigans. Sure, it might wrap back on itself in a mindbending shape, like a of monster donut or nerdecahedron, but if our Universe is infinite, all bets are off.
