Fast radio bursts are split-second intergalactic blips of radio waves we've detected over the last decade. You'd think that if we pointed our telescopes and other space cameras in the direction these bursts came from, we'd spot something else, too. But to date, we have nothing -- just radio waves.

Two months ago, astronomers picked up and then pinpointed the location of a weird burst of radio waves from space, prompting heated debate about the possible source of the signals. Now, new data has finally revealed that source -- and it's not such a big mystery after all. Move along, nothing to see here: Just a star-gobbling supermassive black hole burping out some excess radio waves.

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.
