The Universe is expanding, and goes on for farther than even our most powerful telescopes can see. The part of it that we can see, scientists have long concluded, is indistinguishable from being ...
Most explanations rely on "dark energy" to explain the Universe's accelerating expansion rate, but a new study takes a different path.

Our universe may have been born inside a black hole, study finds
The Big Bang theory has dominated our understanding of the universe’s origin for almost 100 years. It describes a moment when ...
How can the behavior of elementary particles and the structure of the entire universe be described using the same mathematical concepts? This question is at the heart of recent work by the ...
Most people think of space as a flat sheet: You travel in one direction, and you end up far from your starting point. But a new paper suggests that the universe may in fact be spherical: If you travel ...
No matter how elegant your theory is, experimental data will have the last word. Observations of the retrograde motion of the planets were fundamental to the Copernican revolution, in which the sun ...
When you look at your surrounding environment, it might seem like you’re living on a flat plane. After all, this is why you can navigate a new city using a map: a flat piece of paper that represents ...
If you were inside a spaceship traveling in a straight line out of our solar system, where would you end up? Would you keep getting farther from home, or would you slowly loop around and end up where ...
For measuring curvature of 3D (hyper) surface we need solid angles instead of plane angles. General relativity (GR), which explains events on the greatest cosmological scale, and quantum mechanics (QM ...
