Should you find yourself inside a black hole, you will die. Should you find yourself near a black hole, you will also die. Aside from the fact that these massive, light-trapping monsters are impossible to reach on human timescales, there are simply not many ways measure the plasma surrounding them without dying or destroying the experiment. Scientists have to make do by recreating some of the features in the lab.

Predicting the future is near impossible -- but that doesn‘t stop us all from having a red hot go. Human beings have been predicting the future since the beginning of history and the results range from the hilarious to the downright uncanny.

One thing all future predictions have in common: they‘re rooted in our current understanding of how the world works. It‘s difficult to escape that mindset. We have no idea how technology will evolve, so our ideas are connected to the technology of today.

If you were to rank the wildest things in the universe, there are a few obvious contenders: Gamma rays, fast radio bursts and quasars, for example. But no list would be complete without black holes and the black hole's less-dense cousins, the neutron star. These hyper-compressed things can do some mind-boggling warping to the shape of space itself. So, what happens if one were to eat the other?

You are very lucky that you ended up about the size that you are today, somewhere between 30cm and 3m tall and weighing somewhere between 0.5 and 500kg. This is a very good size. Not to body shame, but if you were, say, a quadrillion times shorter and weighed a nonillion times less (that's one followed by 30 zeros), that would be very inconvenient for you. Everything would be very inconvenient for you.
