Sep 9, 2015 · What is the Planck Length? Planck units are defined based on physical constants rather than human-scale phenomena. So while the second is originally one-86400th of a day, the Planck time is based on the speed of light, Newton’s gravitational constant, and Planck’s (reduced) constant, which is twice the angular momentum of an electron.

hbar tells you the Energy/momentum time/position uncertainty, so that the radius at which a black hole's compton wavelength is comparable to its size is the Planck length. This is the smallest distance you can probe, since a particle of Planck energy is required to probe the Planck length, and it will produce a black hole of size the Planck length.

In the same way, when you say Planck length is the smallest possible distance ever, does that mean every particle( or it's constituents) jumps from one point to another where distance between the points is Planck's length, kinda like strip lighting, where bulbs lit in a sequence give the illusion that the glowing section is moving along the strip?

May 23, 2017 · Planck time - the amount of time it would take a photon (or other particle travelling at the speed of light) to cross a planck length - the fastest known speed travelling over the shortest known distance. Time, as distance divided by speed, doesn't get much smaller than that. It is about 5.39 x 10-44 seconds

Planck Time: The Planck time is the fundamental unit of time in the Planck units system and is the smallest measurement of time that has any meaning. The Planck time is the "quantum of time" and is equal to {eq}10^{-43} s {/eq}. Answer and Explanation:

Jan 14, 2008 · The Planck time is the time it takes for a particle traveling at c to cross the Planck length. Also, dimensional analysis shows that the Planck length is the only length that can be obtained from some mix of the 3 important physical constants G, h, c (up to a scale factor), so this shows that it might (must?) have some physical importance.

Dec 3, 2014 · "Transplankian surface" would just be the place where, as you work your way back in time, using the expanding universe model that they use, the ENERGY DENSITY gets above some critical value, like the Planck unit of energy density. Or half the Planck energy density. Something like that. That energy density is amazingly high.

Mar 21, 2004 · The Planck length can then be found with a little dimensional analysis: [tex]GM^2[/tex] has units of length x energy (M is Planck mass, G is gravitational constant) [tex]Mc^2[/tex] is units of energy (M is again the Planck mass)

Sep 14, 2008 · This quantity, t p, is called the Planck time and is thought to be the earliest time, after the creation of the Universe, at which the currently known laws of physics can be applied. Extra info(I don't know is it going to be helpful for solving this question): The smallest meaning ful measure of length is called the Plank length and is defined ...

Aug 27, 2011 · What is Planck time? Planck time is the shortest possible unit of time in the universe, named after physicist Max Planck. It is equal to approximately 5.39 × 10^-44 seconds. Why is Planck time important? Planck time is important because it is the smallest unit of time that can be measured and it helps us understand the fundamental nature of ...
