Planck units

  Need an explanation? The smallest possible black hole is called a Planck particle. It should have a mass of a Planck mass, a size of an Planck length, should evaporate in a Planck time, releasing a Planck energy.

    Ooookay. I feel like I’ve heard Planck length/time used in other (perhaps wrong) contexts. So the mass and energy seemed wildly large by comparison.

  I’m having a Planck IQ moment trying to decypher the four lines of distilled aneurysm with which you just presented me

  Plank length: usually 10ft for 2x4s. Though, you can get them cut to length.

    You can what? You mean I can put down this bread knife and just have my house built for me? I think I’ll keep my sense of pride and accomplishment, sucker…

  I for one like to keep things simple and just express everything directly in units of the number of periods of the radiation emitted by the ground state hyperfine levels of Cesium-133.

  is the energy equivalent to what’s stored in the gasoline? or does the car factor in too?

    10^9 Joules is roughly the chemical energy of a full tank of gasoline. The mass-energy of the car (or even just gas itself) would be many, many orders of magnitude higher.
