Earth and our entire Milky Way galaxy may sit inside a mysterious giant hole which makes the cosmos expand faster here than in neighboring regions of the universe, astronomers say.

One of the easiest ways to do this is with the cosmic microwave background, or CMB. This is light that was emitted when our universe was only 380,000 years old and when it expanded and cooled from ...

For decades, scientists assumed that the expansion of the universe was powered by a new entity, known as the inflaton, but new research suggests that it may have been possible without it.

A Recycled Universe Could Explain Why Everything Is So Flat, Physicists Suggest According to the team, we could be able to detect the remnants of a previous, pre-Big Bang era.

There are theories about the structure of the universe, such as 'an open universe that continues to expand,' 'a closed universe that continues to contract,' and 'a flat universe that neither ...

It suggests that the CMB actually supports relatively simple euclidean (a.k.a. flat) topologies, suggesting that even more complex structures are possible.

The Universe is big, as Douglas Adams would say. The most distant light we can see is the cosmic microwave background (CMB), which has taken more than 13 billion years to reach us.

Essentially, scientists have observed that the CMB is very nearly the exact same temperature in all directions. This was considered strange because the parts of the universe at opposite edges of our ...

A flat universe is a key piece of the standard cosmological model, also known as the Lambda cold dark matter (ΛCDM) model. (Λ is the Greek letter for lambda, denoting dark energy.) ...
