Only if they are super earths.  Needs to have enough gravity to make surface to orbit travel impossible.  I recall some science podcast saying that at 2 or 2.5 earth masses, the rocket equation values for the amount of fuel needed for a human to orbit is exceedingly high.

We need to lock the maga in a gravity well.

That's gotta be a violation of some galactic law regarding dumping of toxic substances

Nah, much easier to just crash them into the sun. Our sun, to be precise in this particular instance.

You mean like Trumpshiatting in a completely unrelated thread?

Very presumptuous of you to assume that Trump voters believe in science.

Well, Fark has officially jumped the shark.

Well, it's in the "habitable" zone for a red dwarf star, which isn't very habitable. It means that theoretically it should be far enough from the star for liquid water too exist, but for a red dwarf star that's really close and means it's almost certainly tidally locked. So it's either blazing hot on one side and super cold on the other, or its atmosphere hasn't been stripped away yet and is covered in monstrously violent storms on a scale we'd have trouble grasping here.

But that close to the star means it's also going to get wailed on by red dwarfs' frequent eruptions, so it probably doesn't have an atmosphere, and has been thoroughly - and regularly - sterilized by solar radiation.

So what I'm trying to say is...

Funny thing about science, you don't have to believe.

It's also probably too small to hold on to its own liquid water or any meaningful atmosphere.

Whale, believe it or not.

Surprised me, too.

It already is exceedingly high. Damn Δv

I think the limit for a rocky planet was 1.6x the radius which is about 5x the mass. That would make the rocket stack required to gain orbit too heavy for chemical engines.

Doesn't really matter. If you add another G people aren't going to be able to live because our hearts can't get the blood to our brains.

Well that won't do then.  There are people on here that say "genocide" is bad, and we can't kill an entire population, no matter what.  So that is what the super earth is good for.  They can terraform it, live on it, and do whatever maga they want.  They just can't leave it, if the rocket equation won't allow it.  A prison world.

They can ooch around on the ground for a couple of generations.

It's a one way trip no matter what, for like, a whole bunch of reasons. Not the least of which........ the trip takes tens of thousands of years. Like 20 on the low end and 70+ on the high end, depending on how fast you're going.

Then, when you get there.... well, you're probably landing on a place something like the planet Mercury, but regularly bathed within more deadly solar eruptions. I think red dwarves are supposed to be a lot more active than a bigger, quiet, yellow star like ours. It's real estate that's probably just slightly more hospitable than the Hellraiser dimension.
