    Scientists are discovering and solving technical problems like this that most of us aren't knowledgeable enough to even know exist.

    "Warm-hot" is such a hilariously modest term to refer to millions of Kelvin. Like, "warm-hot" is how I would refer to the temperature of my coffee when it's been in my mug for a couple of minutes and isn't quite "hot" anymore. Physics and astronomy operate on such a fundamentally different scale you can't even wrap your mind around it!

    I find it interesting that in science that “recently” or “until now” can mean up to 20 gears ago. Lol

    I was learning about the start of the universe - when hydrogen and helium formed - and redshifting in my physics class. This video nicely links them together and helps strengthen my understanding. So, thanks for this video… I truly appreciate it 😊

    No matter how hard we look for it, mom will find it after we’ve said that we couldn’t.
