Yeah, it's like an explosive process because the smaller the black hole is, the shorter is the evaporation time.
So if you start this process going within the age of the universe, it will accelerate over time and you will end up in an explosion.
So Hawking's paper was called Black Hole Explosions.
um so we don't know if that happens um in in nature because there still are some uh theoretical problems with the information paradox um and maybe the the way quantum gravity should be formulated somehow avoids hawking radiation we don't know science fiction writers like using singularities as a power source
Well, I advise to some colleagues that work on string theory to test their theories by entering the nearest black hole, taking a journey there.
And one of them said, when I suggested that, that I have an ulterior motive for sending them there.
Yes, you do.
What would it look like
someone entering the event horizon, what would that look like to the observer watching that?
You would see everything from the universe outside the horizon because it enters through.
But you wouldn't be able to transmit, to send a DM, a direct message to your friends.
By the way, I asked once students at Harvard in my class, I said, if a spacecraft landed at Harvard Square and you were invited in for a one-way trip, would you take it?
My answer is definitely yes.
I'm so frustrated with what we're doing here on Earth that any trip beyond Earth would be worthwhile.
I don't know if your wife would agree, but... Oh, a decade ago, she said, just make sure that you leave the car keys with me.
And also that they don't ruin the loan when they lift off and take you out there.
But recently, just several months ago, I asked her again, and she said, I will join you.
so first this is testimony that our marriage is okay so far uh that now she wants to join me but the truth is that she's so frustrated by reading the daily news uh with what we are doing here on earth that then she she gets my point and so i definitely would go on such a trip but the students told me something that i've never expected they said
We will only go on board this spacecraft if we can use Instagram to share with our friends on Earth.
And I asked them, wait a minute, why would you care about your friends, the ones that you leave on Earth, because you would never see them again?
