The observable universe is vast, extending about 93 billion light-years across, containing galaxies, stars, planets, and all ...

But “infinity” means that, beyond the observable universe, you won't just find more planets and stars and other forms of material…you will eventually find every possible thing. Every. Possible.

So, what is beyond the observable universe? The obvious answer to this is a big "we don't know". In fact, we will never truly know as it is, by definition, unobservable.

A controversial theory suggests the observable universe is the result of matter rebounding after the collapse of a black hole ...

What lies beyond the edges of the observable universe? Is it possible that our universe is just one of many in a much larger multiverse? Movies can’t get enough of exploring these questions.

We may never know what lies beyond the boundaries of the observable universe, but the fabric of the cosmos can tell us whether the universe is infinite or not By Leah Crane 25 June 2024 ...

Our universe is about 13.8 billion years old, and the observable bubble of that cosmos has a diameter of about 93 billion light-years across. And we all know the famous maxim from Albert Einstein’s ...

However, the observable universe extends farther than 13.8 billion light-years in every direction because, for all the time space has existed, it’s also been expanding.

A flat universe agrees with both observation and theory, so the idea now sits at the heart of modern cosmology. The problem is that, unlike a spherical universe, a flat one can be infinite — or not.
