@dr.starkid: Every time you hear the word “habitable planet” you can almost just ignore it in my opinion lol bc it carries so little weight #Astronomy #TikTokLearningCampaign
why does Elon think we can inhabit Mars if it only has 1% of earth’s atmosphere ?

Why do we assume liquid water is necessary for life ??, could life not evolve without liquid water ?

We’re also assuming life as it exists on Earth

Basically you can travel 300 million light years away and end up on Venus or mars

I didn’t have any albedo, but the doc gave me a blue pill and it fixed it 👍🏼

Can we estimate that 1 out of every 5 rocky planets has an earth like atmosphere? Then there World be still something close to billions of potential planets…

Mars should have a surface temperature of minus what?

uuh.. we DO know atmospheres through specral light view.

That is very surprising to me. I just assumed with all the math and spectroscopy scientists had a way more educated guess than .3 for everything🤣 thanks for the video!

But we can measure the content of atmospheres of planets millions of light years away using spectroscopy

Thanks for explaining this so clearly

why wouldn't you use the average albedo of all of the planets in our solar system. surely that would be closer to what to expect, right? I know it will still be very off, but not as off as expecting the same albedo as terra

How does one measure the albedo?

The more I learn the more I come to believe habitable planets, and by extension life, is far more rare than we probably think, or at least want to think.

Do you think our technology could advance to discover more about atmospheres of distant planets?

They don’t have an equation to calculate the atmospheric with relation to this equation?

S I L O :
so, the equation presupposes an atmospheric pressure of 0 and an albedo of 0.3???🤔🤔🤔 interesting

We don’t know how to detect their atmospheres? I thought they could when it passes in front of the hosts star light and can detect what wavelengths are boosted and absorbed so we can tell what’s in the atmosphere
