Where do I donate to help the asteroid?

[–] [email protected] 64 points 1 week ago (21 children)

Is there any way we can speed it up?

Let's point all our magnets towards the sky!

A large enough impulse could knock it onto an impact trajectory in 2028. "Large enough" would be absolutely gigantic though, and we have to catch up with it, making it quite impractical. It would be cheaper to just build some more multi-megaton nukes for the same effect.

Having seen Scott Manley's video on the topic, it seems well within the realm of possible.

[–] [email protected] 6 points 1 week ago

That's for changing the trajectory of the 2032 encounter by a few thousand km, not changing the 2028 encounter by 8 million km. And if we're changing the 2032 encounter we can smack it as it goes by in 2028 instead of playing catch-up before then.

This has been a good test of our planetary defense procedures, and will be an even better test on the off chance the probability resolves to 100%. I'm rooting for an impact trajectory, since we'd either get to see humanity's first real asteroid deflection or witness the largest asteroid impact in over a century. (Hopefully in the ocean or a sparsely populated area!)

[–] [email protected] 22 points 1 week ago (2 children)

Unfortunately, I half expect that if we get a 100% chance, governments are going to see where it's going to land (sea/Africa) and decide it's not worth the spend/let's see what happens if we let it hit.

Really hope I'm wrong, but I don't have a lot of faith in humanity anymore.

Why would we mitigate the asteroid if its cheaper to clean up after a non-consequential impact?

[–] [email protected] 19 points 1 week ago (1 children)

To test our ability to stop it. If one was going to hit a major city, that's not the best situation to be trying something out for the first time.

And hopefully it can be highly rich in rare minerals, so that when the ashes of WW3 finally settle down, at least the future generations of humans or not-human sapient entities will at least get something good out of the whole ridiculous mess we're currently in lol

[–] [email protected] 7 points 1 week ago

Unfortunately, at the speed they travel, an asteroid will be vaporised in the impact. Whatever rare earths there are will be scatter as a fine powder over a large area.

It's only a city-killer, but last I saw there were a few cities in the estimated impact area. Fortunately we'll get a better idea of whether it's going to hit in 2028. Plenty of time to launch a redirection mission or evacuate the danger zone.

3.1% odds are nothing to sneeze at. Ever played D&D?

XCom vets know what's about to happen

[–] [email protected] 6 points 1 week ago (1 children)

It'll climb to 95% and then phase through the earth to somehow miss entirely?

From the article

In a new update, the space agency has increased the chances of asteroid 2024 YR4 colliding with Earth, with the probability of impact rising to 3.1 per cent or one-in-32 odds of impact β€” the highest probability of a collision yet.

IE - 3%.

3% events happen all of the time!

The article stresses that this probability has been going up over the past year or so, which is likely neither here nor there, but I can totally understand how it’s alarming in a post-COVID world.

[–] [email protected] 12 points 1 week ago

Slightly more likely than rolling two sixes.

A direct hit would be about the size of a fission nuclear bomb. Devastating for a city, but no regional or country-wide impacts, let alone globally

[–] [email protected] 11 points 1 week ago (1 children)

Not even a little global cooling?

As a treat?

Good.

first hit moscow and take an insane bounce and hit washington DC please. that's all I'm asking.

[–] [email protected] 9 points 1 week ago (2 children)

It will be in 2032, so near the end of Trump's third term.

Bruh the DC metro area is statistically one of the most anti Trump places in the US. Let's root for it to hit Maralago instead.

is this the aliens going "welp they elected Trump again time to press the reset button"

[–] [email protected] 9 points 1 week ago (2 children)

This is the expected path the probability is going to take. Scott Manley made a great video on that.

Basically the area in which the asteroid is going to be includes the earth. When you shrink this area earth is going to take up more space, unless it left the cone. I.e. measurements increase the likelihood until they don't.

Would asking for it to both hit the Earth and for me to be right below the impact zone be asking too much?

[–] [email protected] 15 points 1 week ago

Unless you are a terrible person, yes.

If it falls on a joint meeting of Trump and Putin who once again decided to have a meeting to discuss Ukraine without Ukraine that should be fantastic, and not at all asking too much. Hopeful musk is hanging out with bezos and Netanyahu and Xi are talking too. Really not asking enough if you think about it

As if fascists and climate change wheren't enough. Here, have an asteroid!

[–] [email protected] 6 points 1 week ago

What if it lands an the fascists and dust in the atmosphere cancels climate change for a couple of decades. Could that work?

How many people need to die before someone hits the Earth with a rock ?
