3/22/2023 0 Comments Planck length and infinitesimals![]() And let’s do that right now!Įxactly how long is a planck length, and how can we visualize it? And exactly why is it the smallest length in the universe? The link to their website is in the description below. ![]() Let’s explore the scale of the universe using some genius animations created by Cary and Michael Huang, who have generously given us permission to use them. In fact a planck volume which is planck length cubed or about 4X10^-105 cubic meters is so small that there are more planck volumes inside a cubic meter than there are cubic meters in the known universe. This is so small that if an atom was the size of earth, a Planck length would be much much smaller than even the head of a pin. For example, the smallest length theorized to be possible, the plank length is about 1.6 X 10^-35 meters. You may not have heard that the universe is even smaller than it is large. That’s thousands of times more than all the grains of sand on all the beaches of the earth. Most of us cannot grasp the scale of the universe because it is utterly unrelatable….to anything that we experience in our daily earthly lives.įor example, there are at least 10 sextillion stars – that’s 10 followed by 22 zeros. Think of the smallest thing you can imagine, a bacteria maybe? An atom? Keep going…because the universe is many orders of magnitude smaller than that.Īnd that’s the problem. It’s much bigger than you can probably imagine.Īnd the crazy thing is that it is also smaller than you can ever imagine. But the scale of the universe is many many orders of magnitude bigger than that. ![]() A blue whale maybe? The great pyramids of Giza? The Burj Khalifa in Dubai? Mount Everest? That may be about as large as you can imagine. Think of the biggest thing you can think of. The scale of the universe is incredibly difficult to imagine. Visualizing Planck length – why is it the smallest in the universe? Visualizing the smallest size in the universe – Planck Length & why you can’t go smaller
