But from our perspective, the outside observers, why do black holes gain mass? It would take an infinite amount of time from our perspective for any mass to even touch the event horizon.
That's the thing that never made sense to me about the black holes. The closer you are to the event horizon, the faster the time passes for the universe around you. So reaching the event horizon should take infinite amount of the "outside time", so right before you reach the horizon, you should see the whole future of the universe, including its end, if there's any.
I feel like they will get sued for that extremely quickly, considering their dominating position (Chrome) and being in the ad-serving business at the same time.
It's still extremely useful, even with those false positive rates. You will scare a few people, but they will just retest and maybe will improve their lifestyle.
Maybe even more, if they invested ALL the dollars into bitcoin since their inception. That would be smart of them in hindsight. If that's the case, they could be sitting on $5B+ worth of BTC (or maybe a basket of cryptocurrencies).
There's a huge difference between what evolved organisms can adapt to, and the conditions necessary to start life.
Look, humans already adapted to being in space for prolonged periods of time. We adapted to every climate. But drop a naked human in a random spot on our planet, and he will die with high degree of probability. And that's after billions of years of evolution.
But corporation collections as paperclip maximizers is a bad analogy. Corporations generally produce something large numbers of people want (be it solar panels or cars in his example), whereas a paperclip maximizer AI produces paperclips that only it wants, destroying everything in its path.
That's not true. They see the universe around them moving much faster.
Time dilation has nothing to do with "returning home".
