Welcome to c/science_memes @ Mander.xyz!

A place for majestic STEMLORD peacocking, as well as memes about the realities of working in a lab.



Rules

  1. Don't throw mud. Behave like an intellectual and remember the human.
  2. Keep it rooted (on topic).
  3. No spam.
  4. Infographics welcome, get schooled.

This is a science community. We use the Dawkins definition of meme.

Aneurysm posting is my middle name :3

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...

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.

By the way, the evaporation of a Planck particule should generate a power of P = Planck energy / Planck time = 3,629 × 10^52 W --> 36.29 million million million million million million million Gigawatts. More than enough to power a time machine.

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

[–] very_well_lost@lemmy.world 0 points 1 day ago

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.

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

Yeah it's missing the text, "...then the Planck X would be..." for the first two.

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.

Truely awful writing.

In my heart, these are the definitions of Planck units.

Quick, someone make a heavier Honda Accord and destroy the universe!

I love how length and time are unfathomably small to even conceptualize, then energy is just like car
