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, ...

(Phys.org)—Although quantum theory can explain three of the four forces in nature, scientists currently rely on general relativity to explain the fourth force, gravity. However, no one is quite sure ...

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 ...

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 ...
