It's strange to me

That Venus is similar to Earth (I believe it has been called "A Failed Earth") but Mars is more hospitable despite its radioactivity.

I always heard in school (many decades ago) that we would colonize Venus, never Mars.

Venus is too close to the sun for one thing, its average surface temperature is about 867 F (its dense CO2 atmosphere also causes a far worse greenhouse effect than on Earth)

@ThirstenHowl That was one of the reasons it isn't habitable. The gravity it too strong and the ground is hot enough to melt lead. Probes only last days on the planet, as oppposed to years on Mars.

Things i learned today.
@FoxyGoddess it seems the only possibility for life on Venus is microbial life up in the clouds where the temperatures are slightly lower. It seems like even thermophilic life from deep in Earth's oceans near volcanic vents would perish on Venus.

We need another Earth-like planet closer to our own orbit to avoid both any asteroid or gamma ray burst that might hit Earth, at least until the sun burns out (after it has grown into a red giant and engulfed Venus). Then we'd need a suitable exoplanet, but then we'd we'd also need massive ships capable of traveling in multiples of the speed of light to get there, so it doesn't seem realistic that humans will ever be able to truly find another home, at least not in the next few centuries, if we're not already extinct by then.

@ThirstenHowl Have you heard the recent theory that we are in a black hole?
@FoxyGoddess no I haven't heard that ... if we are, how are we not being crushed down to subatomic particles by incredible gravity?

@FoxyGoddess interesting, it does seem at least mathematically plausible ... but I still don't understand how we would be alive or intact, my understanding has always been that no matter can remain intact inside a black hole because it's all ripped apart

moreover, we still don't seem to know yet what happens to anything sucked into a black hole after being ripped apart, i.e., what's on the other end / side of a black hole, does everything get ejected out the other side? I thought quasars were the the other "end" but that apparently isn't accurate

@ThirstenHowl The way I see it, black holes are an unknown variable. We really don't know what happens in one because we've never actually witnessed it since it takes so long. So all we have is mathematics and quantum physics to make sense of it. But even quantum physicists have said some things don't work the way they should mathematically, l8ke particle vibrations. So who truly knows until it happens.
