Mar 7, 2025
The hole in the ozone layer has been shrinking in recent decades due to regulations banning the chemicals causing it.

As for the black hole one, I'm not sure. Maybe Hawking radiation?

Arp2600
+11
Level 89
Mar 8, 2025
Yeah, probably "Nothing can ever escape from it" -> Hawking radiation is something that should be emitted by the black hole (but I don't think it has ever been observed).
Sifhraven
+5
Level 76
Mar 29, 2025
My logic was that I considered a black hole a phenomenon not an object.

I had not heard of the Hawking radiation, so I looked it up, it turns out that this theoretical radiation is not something coming from inside a black hole, but would (theoretically) be created just outside it. So it is not technically escaping it, however you could say it being able to stay outside of the black hole is "escaping" it.

But imo it is a lot of hypothethical, theoretical, specaluting etc. So not really material for a quiz (here comes the science debate...)

sumguy

When a rocket orbiting the Moon heads back to Earth, it must escape the Moon's gravity. Hawking radiation escapes a black hole's gravity, regardless of whether it forms inside or outside of the black hole.
RondoNo2

Level 52
Apr 1, 2026
Quantum fluctuations allow a photon to become a particle-antiparticle pair. If this happens at the event hoizon, one member of the pair can be produced outside the black hole, the other inside. Owing to the extreme spacetime curvature, the one inside will be pulled rapidly inwards; by conservation of momentum, the other will move outwards. It is the latter which constitutes the Hawking radiation.

At least, that's what Hawking reckoned. If it does exist, it'll be a very long time before we are capable of detecting it.

LivinAWestLife

Maybe to be more precise, you could escape a black hole if you are outside of the event horizon? Because if you're in the event horizon then there's no getting outta there.

I think the black hole one is because of its MASS, not its density.
Striker
+2
Level 61
Apr 1, 2025
No it's actually the density that causes a black hole. But generally for stars, the mass has to reach a certain point for gravity to be big enough to create such a high density. But it was for example feared that the large hadron collider (or similar accelerators) would cause black holes. This is a possibility, but the black hole would be so short lived, we don't have to worry about being sucked in.

Space Needle is not Seattle's tallest building.

Columbia Center is, nearly 100M taller

The Crusaders DID capture Jerusalem and held it for about 200 years.

The Aztec empire, meanwhile, didn't last a full century before Cortez showed uo.

Ozone hole is healing, though it does get bigger in the southern summer IIRC.

Dragon was not invented in the middle ages, the concept has been around much longer.

Vomitorium were the entrances and exits of large strucutres like the coloseium. People spewed out, not food.

Black hole one... kinda iffy... cause the mass and density go hand in hand in that case...

The hole in the ozone layer over Antarctica is largest during the southern winter, between mid-September and mid-October. Ozone breaks down more easily when it's cold, which is why there's a hole over the coldest part of the world.

I am 100% sure the guillotine was named after Guillotin. So I guess he didn't invent it but just popularized it or something like that?

The cancer question is tough because breast cancer is in fact the most common cancer in women, but not the deadliest - that's lung cancer. Breast cancer can often be cured nowadays if treated early enough.

But what's wrong about the black hole question? If it's about Hawking radiation, I would argue that strictly speaking, it does not escape from a black hole because it is its direct product, just like we would not say that sunlight "escapes" the suns gravity; as far as I know, if any physical object passes the event horizon of a black hole, it can never escape. Its converted energy might be released by Hawking radiation but all of its other properties are irreversibly lost for all we know. But maybe a physicist can correct me on that.

evilcheeser

Guillotin indeed did not invent his namesake, he just recommended its use as a "more humane" execution method. Note that it actually was *more* humane, but that's a pretty low bar...

I don't think that's how Hawking radiation works, but I'm not a physicist.
