The smallest time interval ever defined. Named after theoretical physicist Max Planck (1858-1947), Planck time is 10-43 seconds; however, the only measurement ever actually made was more than twice as ...

Fermilab scientists have been conducting experiments to look for quantum fluctuations of space and time at the smallest scale imaginable according to known physics. At this limit, the Planck length, ...

1.616*10^-35 metres. That's so small. If atoms (~ 10^-15 metres) were planck length diameter, packed in next to each other in an array at planck length distances, and there wasn't any pesky forces and ...

I’d like to invite you to an even higher level of nerdom! Every good nerd knows that E=mc^2. Every great nerd knows that, really, E^2=m^2c^4+p^2c^2 Want to know what that even means? Sure, I’ll tell ...
