Reply to comment by TheRoadsMustRoll in Alien hunters get a boost as AI helps identify promising signals from space by UniOfManchester
Your comment made me realize that there's a deeper assumption at the core: that any aliens emitting radio messages want to be heard.

Disclaimer: I am too lazy to read the article. This is all just prior knowledge.
The only assumption SETI makes is that aliens wouldn't disguise their radio emissions as natural sources. You don't need to understand the signal to realize that it wasn't produced by any known natural phenomenon, and wasn't random.
An ai could quickly filter through the signals, eliminating any that have an obvious natural cause, passing the potentially interesting ones on to people.

Reply to comment by Auphor_Phaksache in TIL black holes also regurgitate matter such as stars that they suck in by Desolecontra
Particles are constantly appearing and annihilating, even in front of your face right now. It's called vacuum energy.
https://en.m.wikipedia.org/wiki/Vacuum_energy
>Vacuum energy can also be thought of in terms of virtual particles (also known as vacuum fluctuations) which are created and destroyed out of the vacuum. These particles are always created out of the vacuum in particle–antiparticle pairs, which in most cases shortly annihilate each other and disappear. However, these particles and antiparticles may interact with others before disappearing, a process which can be mapped using Feynman diagrams.
The process involving black holes is called hawking radiation.

Gros Michel aren't extinct, so you're wrong either way.

Lol, your source is an opinion piece meant for kids.

>Earth’s atmosphere certainly slows and prevents typical asteroidal fragments up to a few tens of metres across from reaching the surface and forming a true hypervelocity impact crater, but kilometre-scale objects of the kind that created the smallest telescopically visible craters on the Moon are not significantly slowed by Earth’s atmosphere...
The atmosphere shielding the surface is not the reason for that lack of craters on earth.

Mars is a cold desert, like Antarctica. Also mars' atmosphere is too thin to allow water to exist in liquid form on the surface, except in special circumstances.

No, it's because of erosion and the fact that earth is tectonically active. Any meteor large enough to leave a decent crater isn't going to be stopped by an atmosphere.

IIRC(applies to entire comment) mars rovers haven't actually been 'driven' since before MER. The rovers have rudimentary AI that takes instructions like "do science on that rock from this picture" and figures out how to do it, only needing humans for complex precise movements or troubleshooting.

Kamaʻehuakanaloa is far to close to the big island to be the next island in the chain, it will join with the island soon after breaching the surface, if Kilauea doesn't fill in the gap before then. In fact, if the increased magma output doesn't slow down, I would expect individual islands to stop being a thing except at the tail end of the landmass, roughly where Kauai currently is.

Put a ring on it to shade the surface. A polar ring at about the right altitude might also give it a more earthlike day/night cycle.

Venus wouldn't be quite that simple. Water vapor is a greenhouse gas. Any attempt to add water to Venus would cause it's temperature to go up, not down. You'd have to cool Venus down first, then add water.

Uv rays don't give a shit about the magnetosphere, they are blocked by oxygen molecules in the atmosphere. That's where the ozone layer comes from.

Reply to comment by SocialMediaDystopian in Trees could reduce mortality from urban heat waves by a third by YoanB
Did you even read the paper? What the paper authors did was take a real heatwave (August '15 I think), model what the cities temps would have been with 30% more trees(something that requires a decent understanding of the effect you claim is just being 'discovered' here), calculate new death tolls from that, then compare the new death tolls with the real death tolls.
Your annoyance is misplaced, scientists know that trees make cities better in many ways, which is why they are performing studies like this one, to convince policymakers and developers to consider the benefits.
