The definition of the Planck length. Source: Wikipedia. Quite often at FQTQ, we like to talk about immense cosmic structures, such as nebulae and galaxies. And as I’m sure you know, there is a realm ...

Quarks and leptons, the building blocks of matter, are staggeringly small. Even the largest quarks are only about an attometer (a billionth of a billionth of a meter) in diameter. But zoom in closer—a ...

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 ...

Planck's Length is the length below which the concept of length loses its meaning. Huh? Planck's Length is the length below which the concept of length loses its meaning. What exactly does that mean ...

At this limit, the Planck length, our classical notions of space and time break down. Imagine the ratio of the size of the universe compared to a speck of dust. That's about how big the speck of dust ...

(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 ...

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 ...

Quantum gravity theory is untested experimentally. Could it be tested with tabletop experiments? While the common feeling is pessimistic, a detailed inquiry shows it possible to sidestep the onerous ...
