What does it take to land on a comet?

From Curious Droid. In days of old comets were seen as bringers of doom and bad luck but now we know better. However, landing on one is probably the most difficult operation undertaken by any space agency and almost a guarantee of some sort of bad luck as ESA’s Rosetta / Philae mission found out.…

The Holographic Universe Explained

From PBS Space Time. We live in a universe with 3 dimensions of space and one of time. Up, down, left, right, forward, back, past, future. 3+1 dimensions. Or so our primitive Pleistocene-evolved brains find it useful to believe. And we cling to this intuition, even as physics shows us that this view of reality…

The Edge of an Infinite Universe

Could the Universe End by Tearing Apart Every Atom?

From PBS Space Time. Of all the unlikely ends of the universe, the Big Rip has to be the most spectacular. Galaxies ripped to shreds, dogs and cat first living together, then tragically separated by the infinitely accelerating expansion of space on subatomic scales. Good thing it’s not going to happen. Or is it? Check…
