An Infinite Universe How Big Is Space Blue Mountains News Fresh Space didn't exist until the big bang. the big bang says nothing about whether space existed before. it may well have done. at that time all of space was compressed to be almost infinity small "almost infinitely" isn't really a meaningful pair of words. space wasn't huge back then. we don't know that either. The short answer is we don’t know. we know the observable universe — the part we can visibly see and measure — began around 13.8 billion years ago with the big bang. so we know the age of the universe is finite at least from the time of the big bang. but the universe is getting bigger.
An Infinite Universe How Big Is Space Blue Mountains News Fresh We know that space, the universe, had a beginning some 13.8 billion years ago. we know from observation that it's expanding and we have detected the cosmic microwave background, which is thought to be leftover radiation from the big bang. space as we see it today is a slowly expanding web of galaxies. The universe has a finite age — 13.8 billion years to be exact. so if it had a beginning, why is it so difficult to say for sure whether it will have an end? is space infinite? we asked 5. "we live in an infinite universe, with infinite stars and planets. into deep space. as powerful as nasa's jwst is, it has its limits. earth's size and proximity to the sun enable it to support. Worse, an infinite universe means that these basics may be unknowable. elmegreen might be content with her 200 billion galaxies. and sure, this playground is vast.

The universe’s geometry determines whether the cosmos is spatially finite or infinite. the geometry could be flat, open (meaning negatively curved), or closed (meaning positively curved). The best current estimate is that the universe’s diameter is at least 93 billion light years. and if cosmic inflation is correct (a long story, but a likelihood), then the visible universe that.
