    How does the atmosphere affect human weight on Earth?

    So humans are slightly buoyant? If I weighed 150 pounds would it be relieving less than a pound? Also how thick would our atmosphere have to be to have it exert pressure on us? For instance like how at certain depths water pressure starts to overcome buoyant forces on an object.

    How does the atmosphere affect human weight on Earth?

    Does Earth's thick layer of atmosphere push down on us, increasing our weights drastically?

    Graduate How do massive stars like VY Canis not turn into black holes

    Apparently VY Canis Majoris is 30–40 solar masses, also there's R136a1 which is 265 solar masses. How do they remain stars with all that mass?

    Undergrad Earth Reaches Sun's Chromosphere: Timing Estimate

    I guess the acceleration time would be drastic. Also, looking at Earth's orbit, I never realized the present velocity was that fast, but that makes a lot of sense for how far it travels in a year.

    Undergrad Earth Reaches Sun's Chromosphere: Timing Estimate

    Wow that's fast! So with 66 days of motion, using the AU as the distance, Earth's moving at about 1.4 million miles per day.

    Graduate What would happen if two Earth size planets very slowly collided?

    Hypothetically this pseudo-Earth suddenly appears and follows the same orbit as Earth, but moves slightly faster. If it eventually collides with Earth at snail pace what would the gravitational effects be like? (maybe ignore the moons)

    Undergrad Earth Reaches Sun's Chromosphere: Timing Estimate

    Roughly how long would it take, ending the time when Earth touches the Sun's Chromosphere layer. (Ignoring interfering with other planets' gravities as it moves toward the Sun, if that situation exists.)

    Undergrad Hypothetical number of ancestors in 399 BC

    Good point. http://www.aisee.com/graph_of_the_month/inbred.gif I guess it gets confusing when cousin or uncle/nephew relationships happen.

    Undergrad Hypothetical number of ancestors in 399 BC

    I was trying to get some idea of how many ancestors I had around the time of Socrates (399 BC is his death), so I tried coming up with a way to find it. So I'll start at my birthday which is 1991. I'll pretend that my parents were both 30 when they had me; I'll also pretend every pair in...

    Wow thanks, I haven't heard of the parasitic wasps before. Amazing

    I just realized I need to watch all of BBC's Weird Nature. But if you know any that haven't been on the show yet...

    I can't believe I never knew these animals existed. I was hoping people on this forum could help me discover more. Leopard slug mating Rolling salamanders & caterpillars Velvet Worm Archer fish Lyrebird

    Best location for stars with naked eye

    These places seem great. Do places like these actually appear this way with the naked eye?
