Ten events that would unfold if gravity suddenly vanished, beginning with the effects on our bodies and ending with the ...

What if gravity isn’t weirdly quantum at all, but rather … just a bit messy? The holy grail of theoretical physics is to find the long-sought theory of quantum gravity. But what if this theory is as ...

Firing a gun in space plays out very differently from that on Earth due to some bizarre physics. Here's everything that ...

Our universe would look so different, Kyle. You might not recognize it even if you could be here to see it. Unfortunately, there probably wouldn’t be a whole lot to see. I learned about this from ...

Bad things happen to a human body in zero gravity. Just look at what happens to astronauts who spend time in orbit: Bones disintegrate. Muscles weaken. So does immunity. “When you go up into space,” ...

Blue Origin will launch its first suborbital rocket launch of 2025 today — and attempt a wild spin trick to mimic the moon's gravity during the flight — but if you want to see it live, you'll need to ...

The holy grail of theoretical physics is to come up with a quantum theory of gravity. But after a century of trying we really have no idea how close we are, or it it's even possible. But we shouldn't ...
