A kid asked physicist John Cramer if anyone actually recorded the Big Bang. He said no, but then set out to make his own recreation.

NASA has announced new findings that indicate that the Universe is 100 million years older than previously estimated.

The universe is a big place. Strictly speaking, it's the biggest place there is. And since so many bits of it are so far away from us, it's hard to get a sense of the overall structure. The Sloan Digital Sky Survey has been working hard to detect and measure everything out there it possibly can, and the latest release is a breathtaking 3D map.

Eventually, the universe is going to die. It's not going to be soon, but it's going to happen, and when it does, our top priority should definitely be to have a computer that can survive it. Theoretical physicists have speculated that we can do this with something called a time crystal, and they may have just figured out how to actually make one.

This is a picture of a small patch of sky, taken by the European Southern Observatory's Visible and Infrared Survey Telescope for Astronomy (VISTA). With the exception of a few stars, every single pixel of light in this image represents an entire galaxy, and you're looking at more than 200,000 of them.

It's not easy to figure out how far away other galaxies are. Astronomers have to be exceptionally clever to calculate distances to objects that are billions and billions of light years away, and they might now have a brand new measuring tool that involves supermassive black holes and radiating gas clouds. Sexy.

With a few exceptions, space seems very static to us humans with our short lifetimes. By stitching together some 14 years of Hubble images of young stars emitting huge jets of gas, astronomers have created videos that show how dynamic our universe actually is.

You probably didn't know that the universe runs on gas. You also probably didn't know that the universe is rapidly running out of gas, and galaxies have been slowly dimming like spent flashlights. Should you panic? Yeah, I'd say so.

We live inside a universe, that much is (more or less) certain. What's less certain is what exists outside our universe, but scientists now think that they might have spotted evidence of other universes, four of which seem to have smashed into us.

Have you ever had a sneaking suspicion that the entire world is just one giant hologram? For better or worse, this now seems less likely to be the case, according to the latest results from a gravitational wave detector. Yes, we have those.
