There's a mysterious account called "Master" playing online Go, and it's so far unbeaten, playing over 50 games against the world's best professionals.
Right now, there's a player lurking in the depths of the online Go scene that is laying waste to some of the best players in the world. It's called...

Not very high statistical power yet, but hints of a deviation at black hole event horizons from the predictions of general relativity.
Gravitational-wave data show tentative signs of firewalls or other exotic physics.

Tang Weixing, one of the best players in the world, reviews his game with AlphaGo (in Chinese with English subtitles). At the end they discuss just how effortlessly AlphaGo seems to win:

“M: Okay. Review over. Maybe talk about your feelings a bit more? You knew it was really strong before the game. Your thoughts after?

T: Before I thought, at least I understand its moves. Now I don't know what to think... How did I lose? I understand the purpose behind its moves. When you analyze, the purpose is always clear. But when you're playing, you sometimes just don't understand. When you figure it out, it seems like the game is already out of your control.

M: After it plays the deciding move, you really don't have any resistance.

T: Actually its moves looked super simple, aside from that attachment. Maybe if you analyzed it more, you could find the attachment too. Where did it play particularly brilliantly? Seems nowhere? Attach, attach, keima, then the tsuke tesuji. Crawled when it had to.

M: The level of understanding is different. Not really playing in a bunch of different places that we wouldn't think about.

T: But the way everything comes together... everything is just better. Better than us.

M: We don't stand a chance.

T: Whether or not it plays strongly or slack... after a few moves, it always seems like you don't have enough. Even if you try to pick a fight... it'll disarm you quite easily. Then it'll take control of the game. You can't force it into a decisive battle, it seems. No fighting, it'll just make some plain moves... and you'll be behind.

M: We'll learn from it some more, in the future. How big of a difference do you think it is?

T: If it's fast, I have no chance. If it's slow... after looking at its games... If I get sente (Black, no komi), I can't win. Maybe reverse komi [effectively a free extra move at the beginning]… Maybe I still have some confidence left? But really, I wouldn't bet money on that either.”

“Master” (AlphaGo) still unbeaten, now with 60 wins against the world's top professionals. Ke Jie, probably the world's #1 player: “After humanity spent thousands of years improving our tactics, computers tell us that humans are completely wrong.”
A mysterious character named “Master” who has defeated many of the world’s top players in the ancient strategy game of Go has been unmasked.
