how can something be profoundly smaller?

Question

how can something be profoundly smaller than the nucleus of the atom, this is what string thoery says? ..Hey listen; I get Einsteins fabric concept of space, but string theory,just spaces me. How small can you go?

pretty crap link, you guy.

I t didn't work on my puter.

Answer 1

IAW string theory, there is a physical limit to how small something can be...the Plank length ~ 1.6 X 10^-35 meter. [See source.] To put this in perspective, if your fingernail were expanded to the size of the observable universe, a Plank length would be about the size of your real fingernail.

Perhaps more incredulous is that strings are supposed to be infinitely small...whatever that means. I find it somewhat inconsistent that string theory was in part concocted because relativity broke down at the subatomic level and yielded what we call infinity. Physicists, according to Greene, cannot accept infinity as an answer; yet they turn right around and posit a particle that is "infinitely thin." [See source 2.]

Answer 2

Actually, an atomic nucleus is made from smaller particles (protons and neutrons) which in turn are made from smaller particles called quarks. The smallest meaningful distance is referred to as the Planck length (named after the the physicist Max Planck, who was probably the founder of quantum theory). There is also a Planck time and Planck mass, which in quantum theory are the smallest "amounts" of these variables that can have a physical meaning.

Answer 3

to infinity smaller theoretaically

anyway

watch bbc video

for some understanding

Answer 4

I that no matter how small you get,there is smaller still
