    Here Mr."Scientist", it looks like you could use a refresher on lesson one.

    All this talk about gravity is really bringing me down.

    I had to re watch the video because I was reading the stupid unit of measurement argument in the comments?

    I think what he meant really was that scientists in very specific fields would use something more like natural units, where you redefine some constants (to equal 1, for example) to make calculations easier and you thus move away from SI units. Also, lots of scientists are indeed still stuck with some system of units because they are more convenient.

    "I just asked for one....about a week ago..and still haven't heard anything. " I literally sent you 3 different papers using non SI units and I sent it twice.

    Why are you lying?

    I'm still waiting for that one scientist who has claimed publicly that he does not use SI units. He would have had to make that statement publicly for you to be aware of it. Not thousands. I just asked for one....about a week ago..and still haven't heard anything. Again, if you want to make baseless claims, that's fine. This is Youtube. If you want to be taken seriously at all by logically thinking people, you're gonna have to do a hell of a lot better than 'the vast majority' with no support.
