Neptune - Alarmingly Bad
(lemmy.world)
This is so fucking dumb and I love it so much.
If it didn't just disappear I bet it would be blamed on a rouge micro black hole flinging out of orbit
My favourite option would be if it lost all momentum, just completely stopped while we kept moving
If it just lost momentum, it would fall onto the sun, but it would take about 29 years to fall, meaning it most likely fell into another planet possibly derailing it, too, and so on. And this doesn't consider that its gravitation would likely start affecting orbits long before it actually hits anything
Your forget that the sun isnt stationary. Our whole solar system would slowly move away from anything truly stationary while we continue our orbit of the milky way. It would take a good while but after a few years neptune would be pretty far from the sun. If it got stopped while in the path of the sun tho, it might just get run over by the sun and we would all die.
You forget there is no absolute inertial system and what you describe is completely arbitrary and makes no sense.
The whole concept of a celestial body just stopping somewhere without exploding into dust is also arbitrary and makes no sense.
Of course it makes sense - a genie did it. Pay attention!
True true, my bad.
I guess you could be stationary relative to the CMB?
You could, but that frame of reference is not special in any way.
That's why I define all movement based on a reference frame centered on me.
I wasn't speeding, officer. The road was.
- "Do you know why I stopped you?"
- "You didn't. I was at rest the whole time."
Ooi. As you seem to have a hold on the physics.
My first thought was. If a planet the size and location of neptune just vanished.
What effects would that have on the rest of the solar system. Given Pluto was found due to its effect on neptune I think. And this is a relatively small mass on a larger one.
I'd be very interested to hear opinions on what the sudden disappearance of a planet would do.
Just to put everyone's mind at rest. I am not an evil scientist working on quantum teleportation.
That said. Feel free to consider other planets. ... such as jupiter. ;)
Not sure if that would be as simple as estimating the falling time. Most likely, it will change the revolution period of other planets, but my guess is that nothing dramatic is going to happen. Would love to see a simulation of that, of course ❤️
Check out Universe Sandbox on steam. Open the Sol system and delete a planet, change all the settings add black holes
Well, I tried to remove Neptune in Universe Sandbox, it did nothing (as expected, tbf). I tried to remove all the planets except the Earth, and it spilled moons all over the solar system, but none even hit the Earth in a hundred years of simulation. Earth seemed to go slightly faster on the orbit (very slightly, though)
The sandbox looks pretty meditative, but also seems like it could do as a good education supplement, thanks for the hint
Yeah, I normally used it to play with the gravity of the sun or the planets. It is a free sim but with what I was doing it was fun to watch the planets fly out of the system.
No I mean if it stopped in place relative to the galqxy and everything
You'd need to specify a reference frame, as there is no universal "zero point". Probably the most sensible choice would be the CMB rest frame though.
That sounds overly complicated I just want to not move, we have an estimate on how fast everything is moving so why not just remove that plus the expansion of the universe to have it hold still
Don't know, with the context of the solar system and the planets sun's reference frame looked more sensible. Stopping in the CMB frame may have been more spectacular, true
Do it!
I'm laughing so hard. I'm so high.
Second wish: Brand new, active volcano in the middle of the Sahara Desert.
"I wish for you to yeet Neptune out of the Solar System"
- Pluto
"Who can't clear their orbit now, asshole"
Basically the plot of the three body problem, where scientists go mad because fundamental physical phenomena no longer follow the usual rules
Why does the New Roman Times use correct font only for name, but not headlines?
I genuinely laughed - a rare occurrence with webcomics!
This is so absurd lol. I like it.
This would have some amount of effect on the earth, though I'm not knowledgeable enough to say what the effect would be. I could imagine the result being anywhere from "it's measurable with scientific instruments" and up to "all life on earth will die within hours".
~~Off the top of my head iirc Neptune prevents a huge amount of large meteors from hitting the earth, so i think for that reason alone it would lead to earth being frequently hit with meteors that each cause nuclear weapon level of destruction.~~
EDIT
Actually Jupiter is the planet that protects us from asteroids, so that specific effect probably wouldn't be in play
Unlike your priest, this guy didn't try to touch uranus first.
