Maybe you can repack it in bigger bottles so the air has more space to expand

- Comment on Black Holes 1 week ago:
In General Relativity, the way to get gravity so strong that not even light can escape is with a singularity: a point of infinite density. So, either this infinity physically exists, and maybe we’ll understand how better, or General Relativity may be incomplete: a model that works well most of the time, but doesn’t represent reality correctly at the extremes of heavy mass and small space.
Or at least that’s how I understand it. This has more info: …stackexchange.com/…/why-singularity-in-a-black-h…
This is similar to the ultraviolet catastrophe. Physicists predicted black body radiation using their current physical models, with high accuracy at low wavelengths of light, but at high wavelengths, the predictions diverged towards infinity, which disagreed with measurements.
Breakthroughs in quantum physics later reconciled theory with measurements.
One big difference with black holes is we cannot yet measure the actual density in the interior of the black hole. We just have the prediction that there is a point of infinite density.

This whole comment was a struggle to type on my phone at the time because the screen was wet, so at the end that one slipped though.

- Comment on Black Holes 1 week ago:
And an infinitely dense point in spacetime doesn’t necessarily exist: it’s just what general relativity predicts is at the center of a black hole.
The last time our physical model of the universe predicted an infinite value, we ended up discovering new physics eventually (the ultrasound catastrophe).

That makes sense.

I don’t think adultary means “sex outside of marriage” I think it means “sex outside of marriage”. Big difference.
Maybe I’m dumb but I don’t see the difference here?
- Comment on Why can't a liquid move faster than the speed of sound in that medium? 4 weeks ago:
Does this mean that a drop of water can’t move through air faster than the speed of sound in air?
Or that a drop of water can’t move faster than the speed of sound in water anywhere?

- Comment on What are the privacy risks of exposing IP adresses? 5 weeks ago:
No I mean if the police can get a warrant to look up your billing info with the ISP, then the employees at the Isp must have some kind of access too. Can theoretically someone could hack in and steal the info.
- Comment on What are the privacy risks of exposing IP adresses? 5 weeks ago:
If the Police can come right to your door, I assume that your ISP has your home address linked to your IP. Could anyone else access it?
