Anyway, I wouldn't be surprised if you could actually do hard computations with semiclassical Einstein equation, because they have strong self consistency - the expectation value of the stress energy tensor curves the metric, which in turn excites the quantum vacuum and causes expectation value of the stress energy tensor. But this isn't what they use in the paper. Nobody knows if this self consistency can be achieved in all configurations, and physicists working with semiclassical gravity usually do only one iteration of the self consistency.

If someone wanted to make semiclassical gravity into quantum gravity, he'll probably assume that gravity causes measurements, which would prevent these kinds of abuses where you have superposition you're probing via gravity while keeping it intact.

North Korea didn't fund terrorism. North Korea isn't an aggressor. You cannot compare them at all.

Israel and the US were monitoring Iran nuclear development and Iran knew that. They wouldn't allow Iran to rush to nuclear without striking them first, like it had happened.

If you're a dictator and you want to learn the lesson from Iran, it isn't to get nuclear weapons. It's too not call for the destruction of Israel and the US and to not fund terrorism.

The only thing gaza didn't have under Israeli occupation was democratic election. And guess what, they didn't have that after the occupation stopped either. They don't have it in most Arabic countries either.

How is that allowed while what I said isn't? My parent comment literally says the same thing. Your moderation is one sided. I didn't say anything that wasn't claimed by the other side.

I see far worse slurs about Israel and Jews here which remain unmoderated. And you won't even let me attack them back.

Even according to Hamas only 200 died out of starvation, and that number is disputed as well.

This is all Hamas propaganda that everyone believes.

If Israel wanted to kill two million, they could've done it already.

It seemingly doesn't matter how accurate Israel tried to be, they call genocide either way.

We're not here to win the victimhood competition. This isn't 9/11 where the U.S living peacefully wasn't threatened. If we don't eradicate this threat our cities will be assaulted again.

We're here to live in peace, and if that means eradicating hamas while there are heavy Palestinian casualties, so be it. That's the only option for us to live in peace. This is an existential war for Israel. There are relatively few casualties compared with what would've happened if Israel actually decided to genocide the Palestinians. We could've killed them all if we wanted, but we only fight Hamas as we must do. Eradicating Hamas is a daunting task. We're actually fighting selectively at the cost of our soldiers lives. If the intention was genocide the Palestinians would've been dead by now. The intention is to destroy Hamas at minimum causalities.

If you want to take into account the evaporation of the black hole, then you should look at something like the vaidya metric. The mass function is a function of the ingoing Eddington coordinate v, which takes on a specific value when you cross the event horizon, and so you observe the black hole at a specific mass as you cross the event horizon. Contradicting your layman understanding of time dilation for the observer relative to the black hole.

Once you cross the horizon, the r coordinate becomes timelike, and so you are forced to move to decreasing r value just like a regular observer is forced to move to increasing t value. Your entire future, all your future light cone is within the black hole and it all terminates at the singularity. Minewhile, the t coordinate is space like which is what gives you space like separation from the mess that had happened in the original gravitational collapse. You wouldn't be blasted by a frozen supernova like you have said.

You can kind of say the universe splits at the event horizon, the time like coordinate changes from t to r and the future of the black hole branch of the universe is permanently cut off from the rest of the universe.

In rotating and charged black holes it is different, and you observe the evaporation of the black hole once you cross the Cauchy horizon. If the black hole is eternal (because someone kept feeding radiation to the black hole, maybe by reflecting the hawking radiation inwards), then you would in fact see timelike infinity as you reach the Cauchy horizon, so this time like infinity is quite physical. You would need to avoid being vaporized by blue shifted incoming radiation.

Did Google's experiment encounter problems when trying to run RCS on the full 105 qubits device?

Before saying that the computation invoked parallel universes, first I'd like to see that the computation couldn't be explained by the state being encoded classically by the state of the particles in the system.

Remember macroscopic objects have 10^23=2^76 particles, so until 76 qubits are reached and exceeded, I remain skeptical that the quantum system actually exploits an exponential Hilbert space, instead of the state being classically encoded by the particles somehow. I bet Google is struggling just at this threshold and they don't announce it.

The "you won't notice crossing the event horizon" troupe is true only in a very local sense. If you move around and observe the geometry around you, you can definitely tell you're inside a black hole.

Inside of black holes looks nothing like ordinary spacetime. Inside black hole, everything in your future is with decreasing radial coordinate, which means space is shrinking until you hit the singularity where radial coordinate is zero and you have no future.

1k out of 8 million is 1 out of 8000.

Every person in Israel knows someone who knows a victim personally. Think how deep this trauma is to Israel.

Gravity is extremely non linear, when you look at the expression for Ricci tensor, it is much more complicated than other forces.
