Wow this is the most depressing comment section I’ve ever seen.

Yeah, even for Lemmy this is bad. I hope most of them are semi-facetious?

it’s just standard “haha self harm funi”, it’s so easy to post and reliably gets a few upvotes, so it’s just a kneejerk response to posts like these.

Which direction do I need to fart to up those numbers?

No stacking software just contrast correction

Well no. By definition it had Venus-like life.

Not ruling out some stange bacterial life that’s generating phosphene however. Come on space agencies, Venus atmosphere sample mission when?

What?! Nobody told me that we got a new moon.

We literally did, you just weren’t paying attention. That should teach you!

Is is the theory that little, invisible gremlins are just constantly pulling things down? 🤔

Looking at the moon is always fun.

Gork, rok temu w Dark Matter Black Holes Could Fly through the Solar System Once a Decade

What would happen if one of these tiny black holes hit Earth? The article doesn’t really talk about it.

Donjuanme, rok temu

Absolutely nothing.

Also not sure why they wouldn’t evaporate nearly instantaneously. Sounds to me like more dark matter bunk.

Passing near the earth, we’d get some strange tides. Passing through the earth, it would eat earth.

Rhaedas, rok temu

Nonsense. The event horizon on such things is incredibly small, as is the mass vs. that of Earth.

deegeese, rok temu

You don’t need the event horizon, you just need local gravity around 1G. For the masses described in the article, that radius is from hundreds of meters to 10s of kilometers.

Rhaedas, rok temu

Which still wouldn't do what you suggest. The mass is the same, so it has the same effect from a distance. Unless by "eat earth" you meant it would take in dirt until it suck to the core, still about the same mass.

I did some analysis and then tested everything myself. I’ve now arrived at the only possible conclusion: it’s aliens.

Damn, it’s happening. Finally, my anti-alien insurance will pay off.

Who’ll pay it off, though?
