    3:58: id like to add for anyone watching in 2022 or later that now there is evidence in support of much of the heavier elements (like gold, uranium, etc) being formed from neutron star mergers, not just supernovae, which is pretty incredible

      +Trace Dominguez If weight is relative, we can weigh anything in the universe relative to our own definition of a kilogram.. On another planet 1 kilogram would be relatively different based on that planets gravity, but we'd still be able to easily convert between them.. So why is it wrong to call it "weighing a star"?

      +Trace Dominguez You should have mentioned the nemesis theory, the sun "may" have a binary twin star...

      +Christian Bendtsen Kilogram isn't a unit of weight, it's a unit of mass. Newton is the unit for weight (i.e. the force excerted by gravity)

    You could weigh a star by calculating how much it's matter would weigh relative to Earth's gravity. It's a useless measure but it would be a cool way to show just how massive a star is.

    cant we just use the redshift + brightness?
    redshift tells us velocity, and thus distance
    apparent magnitude is how bright the star appears on earth
    by knowing the distance we can make corrections to find the true brightness of the star
    by knowing the brightness, we know the rate of nuclear fusion
    by knowing the rate of nuclear fusion, we know the mass.

    question. what is you educated guess on the outcome of 2 nearly dead / dead stellar core impacting each other? lets say they strike at between 30 and 45 degrees of each others angular momentum at what ever speed would be reasonable for one or both moving. would they merge, fracture, shatter or bounce off each other... odd question i know :) but inquiring minds (mine any way) what to know! :))
