If you want another video to make you think this way, I'd recommend CGP Grey's video 'Metric Paper' about paper dimensions with relation to the universe.

I'm skeptical about that. A few days ago, a news article was posted on this sub, where a hot gasgiant with a silica atmosphere was found orbiting a binary star pair at 9x the distance between sun and pluto. We're presently using many instruments and technologies to observe exoplanets and transit method is just one of them.

Never say never, but the evidence in our own solar system indicates that Jupiter was also on its way inwards until stopped by Saturn. So it may be that gas giants make their way inwards by default unless circumstances dictate otherwise.

My takeaway from this and other such articles regarding exoplanets is that it seems much more common for gaan giants to be orbiting near their star, and it seems Jupiter is an outlier in that sense. It seems Jupiter would've also been this way if not for the formation of Saturn whose gravitational pull stopped it advancing inwards and caused it to retreat back to where it presently is.

If you're curious not just about Venus, but for most of the planets and how they evolved, then I'd recommend watching the Mini Series 'The Planets (2019)' hosted by Brian Cox. It's only 5 episodes and they're pretty informative.

Reply to comment by AnotherDreamer1024 in Would building a Dyson sphere be worth it? We ran the numbers. by cad908
Honestly, didn't read the article, it was a bit too long, but to further your argument, a Dyson sphere doesn't have to be a solid sphere encapsulating the star. One can theoretically put a swarm/lattice of 'dyson satellites' in orbit around the sun to achieve the same effect. What holds back the concept of a Dyson sphere as a valid energy source is not our satellite building tech or mining abilities, but that we don't yet know how to transmit this energy that's generated in Space onto Earth without frying it.

Plus, Venus is technically in the Sun's Goldilocks Zone. If it weren't for the runaway greenhouse effect, it might as well have been habitable. There are some models that do hint that Venus had water oceans like Earth for a few million years before its atmosphere took a turn.

Pretty much this. I think there are gifs and videos of this being simulated too.
What I would like to add is that the merger and gravitational interaction of the matter within both galaxies will also result in a new burst of active star formation as the gases and nebulas within both galaxies are acted upon by various forces during the merger.
As for our Sun, it would be in its late stages, either nearing it or having already become a red giant and swallowing up the inner planets. So unless we have become a space faring species and spread out to other stars, we'd more likely be extinct.

Reply to If earth was a smooth sphere, which direction would water flow when placed on the surface? by Axial-Precession
If I remember it right, the motion of water on earth, at least the oceans, is dictated by the tidal forces of the moon and the spinning of the earth, and sometimes also due to sub-ocean earthquakes. Regardless of the earth's shape, these forces would still be active.

Maybe. But this one is 9 times more distant than the distance between Sun & Pluto, is what caught my eye.

How is the planet hot enough to have such an atmosphere when it's so so distant from its host stars? Many times farther than Pluto is from the Sun.

Two factors, reputation and price.
For example, Indian Space agency, ISRO, has a much better track record at launching satellites, and has developed means to send multiple ones in the same payload. Recently, it launched 36 (or 32?) satellites for a UK based StarLink competitor as part of the same payload. It also holds record for launching 102 satellites at the same time. It has launched satellites for countries around the world, including the USA and Israel. And it's costs are competitive.
