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

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

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

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.

[–] unexposedhazard@discuss.tchncs.de 1 points 2 months ago (1 children)

The whole concept of a celestial body just stopping somewhere without exploding into dust is also arbitrary and makes no sense.

[–] Klear@sh.itjust.works 1 points 2 months ago (1 children)

Of course it makes sense - a genie did it. Pay attention!

True true, my bad.

[–] CheeseNoodle@lemmy.world 0 points 2 months ago (1 children)

I guess you could be stationary relative to the CMB?

[–] Klear@sh.itjust.works 1 points 2 months ago

You could, but that frame of reference is not special in any way.
