What if the hardest part of warp drive was never bending spacetime, but finding matter that physics could actually tolerate?

Spacetime itself would also need to be “quantized,” or broken down into constituent parts. This is what the notorious string theory attempts to do, as does loop quantum gravity, currently considered a ...

The far future of the cosmos may be less endless than it once appeared. New calculations place the decay of the universe’s ...

For over a century, scientists have been intrigued to decode the perplexing scenery behind contemporary physics. It's been up for many years, and yet the experts still have no idea how to bridge the ...

When speaking of our universe, it's often said that "matter tells spacetime how to curve, and curved spacetime tells matter how to move." This is the essence of Albert Einstein's famous general theory ...

Time feels like the most basic feature of reality. Seconds tick, days pass and everything from planetary motion to human memory seems to unfold along a single, irreversible direction. We are born and ...
