Hey um, I think you made a problem in the video lol. When it says radius and mass, you didn’t put what they were in. So it’s just “radius: 0.78” and “mass: 0.3”.

[@Ojisan642]

Love it. Suggestion for next time - put the temp in relative units Kelvin. So Earth is +0K, Trappist I-d is +3K, another planet would be -29K etc. That would make it consistent with the radius and mass measurements being relative to Earth. Edit: you know what else might be cool, the relative gravity at the surface of each planet.

Kepler-296f is able to make a sponge instantly flatten. That’s a lot of gravity

[@CasabaHowitzer]

It's probably too much for humans, but life can exist on very heavy.

[@mr.constipation2041]

If there would be life existing there, they would probably be stronger and can take on the gravitational force of its planet given that they are in or close to the habitable zone. Or perhaps there may be creatures that can withstand to live on planets far from habitable zones.

[@ccv1929]

@@mr.constipation2041 Yeah, but the kind of life on there would be in comparison to earth life, extremely little. This is because if a life form has less mass, the gravity on them is not going to make larger problems.

Harry make a video of about what would happen if the smallest black hole hits the biggest star in the universe

[@m.s.9158]

Some of the planets might have heavily overestimated mass, which would make gravity 5 times stronger on the surface than on Earth. Regardless, amazing video.

[@methanoid]

Yeah I would have liked to have seen surface gravity on the specs of these exoplanets. 5 times mass doesnt make 5 times gravity if the radius is larger ;-)

[@DeMooniC]

True, A lot of them were neptune sized or smaller and for some reason its mas was 30 earths

[@darthvader0219]

Kepler-298d has a mass of 6.8 times that of earth, not 30. I’m not sure where he got the masses from.

[@lamalien2276]

There is reason to speculate 'superearth' type exo-planets are common actually, look at the research. And I think the OP used a calculator to arrive at the surface gravity, which I did too and found many to be with a gravity of 3-5 that of Earth. Unless the mass estimates are significantly off this seems to be the case.

[@user-xl8hk2nm9g]

I cross checked the masses of some of these planets, and they are indeed often overestimated by a factor of 2 or more in some cases. In one case the mass was correct but the radius was 30% smaller, resulting again in overestimated density by a factor of perhaps 3. Otherwise a very good video.

Wrong, our legs would not explode at all, although there would be some strain on the muscles. Jupiter’s gravity is 2.5x earth and pilots can survive levels up to 9x.

[@cheungjame637]

IDK seriously

[@jp2650]

You seriously think that life could proceed on such a planet??? Wow

[@camacakegd3714]

The planet Kepler-298d wouldnt have 30G, because its mass is spread out over a greater volume. If its 30 times the mass of the Earth, then its gravity would be about 4.8g. But even this is unlikely, and its mass is probably more around 7 times Earth's which would make its gravity just 1.12g. That's not much higher than what you're experiencing right now.

Can you add your time comparison video back?

[@dmonkeyluffy62]

I can't see how most of these exoplanets could be possibly habitable without the use of some sort of exoskeleton. Most of them have a gravitational acceleration of more than 3g, as calculated from their masses and their radii squared shown in this video. I don't think most of us can withstand being pulled by more than 3 times our terrestrial weight down to the ground and still perform everyday tasks.

[@AlexEvett55]

I'd say 1.5G would be the practical limit. I've been under 3G and 5G for extended periods and any more than 3G you can't even raise your arms or head. Maybe I'm just weak though

[@dmonkeyluffy62]

@@AlexEvett55 Nah, I don't think you are weak, but not very strong either, as most of us are not. At least not enough for this sort of environment (over 3g). Think about it for a second, do you know many 80kg men who can constantly carry around another 160kg strapped on them?
