Are we living in “The Matrix” in real life? In the 1999 science-fiction film, Neo discovers that the universe is a simulation — but one scientist believes that the idea isn’t all fiction ...

Mathematical evidence indicates that our universe is flat, but it could be infinitely big, as well. You can figure out if an object is flat with a simple pencil-and-paper geometry exercise. To ...

“In physics, there are laws that govern everything that happens in the universe, for example how objects move, how energy flows, and so on. Everything is based on the laws of physics,” Vopson ...

The largest sample of galaxy groups ever detected has been presented by a team of international astronomers using data from the James Webb Space telescope (JWST) in an area of the sky called ...

In such a universe, exiting the top of the cube would bring you back to the bottom, but rotated by, for example, 180 degrees. The new study considered a total of 17 possible nontrivial topologies ...

While no evidence of a parallel universe has been found, that doesn't mean the idea is off the table. Several scientific theories, such as cosmic inflation, suggest the possibility of a multiverse ...

A Universe Born in Reverse. The most straightforward explanation, according to Gorham, is that the Big Bang created not just ...

The claim: NASA recently discovered a parallel universe where the laws of physics are “reversed,” and time flows backward. The internet was briefly captivated by the idea of parallel universes ...

The universe is still expanding at an accelerating rate, ... For example, the cosmological constant could be replaced by some kind of field linked to some as-yet-unknown particle.
