I’ve looked at most of the Planck units. Planck length which is really tiny, Planck time which is really short and Planck temperature which is really hot, but there is one I’ve been sort of putting off, and that is Planck mass, which is kind of strange, let’s find out more. Unlike my other Planck unit videos we don’t need to try to use our imaginations to visualise how big or small this is because we can easily imagine how heavy this is. This is about 10 times heavier than a human egg cell or about the same mass as a human eyelash. So how does this compare to the mass of other things. Specifically how does this compare to the masses of particles and the like.
