Think of a mystery musical instrument. If a physicist is told the loudness of the sound it makes at every possible frequency, ...

Considerations of the geometry of the universe can be split into two parts; the local geometry relates to the observable universe, while the global geometry relates to the universe as a whole ...

But it’s also possible that beyond the boundaries of our observable bubble, the universe is curved. That would mean it only appears flat to us because we only get to see a small portion of it.

Understanding the shape of the universe is notoriously difficult. When it comes to local geometry, scientists are relatively certain that the observable universe is flat—or, at least nearly flat ...

The universe may be vast, but researchers have multiple points of evidence that reveal its shape. When you purchase through links on our site, we may earn an affiliate commission. Here’s how it ...

The shape of space-time could tell us 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 ...

Scientists say the Universe has no edge, but that doesn't mean it's infinite. A Manchester astrophysicist explains what we ...

The observable universe is 92 billion light-years across and contains about 2 trillion galaxies. Telescopes can only show us the observable universe; we can't see beyond that. The universe's shape ...

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.

How did everything begin? It's a question that humans have pondered for thousands of years. Over the last century or so, ...
