It's not just how big but also how small.
It was said on a program about the universe/physics I saw at some point that the Planck length, a very very small size and I believe the smallest understandable size, is so small a good way to comprehend how small is thus...
Using a pencil put a very small dot on a piece of paper, a dot that you can just see. If that dot was then expanded to the size of the observable universe the Planck length would be the size of the original dot you drew compared to the expanded dot at its original size and the new dot scaled backwards as well.
I'm sure it was explained far more eloquently than I just paraphrased it.
To quote Eric Idle "And pray that there's intelligent life somewhere up in space, 'Cause there's bugger all down here on Earth."
wow, and stolen for another forum
thanks
Just time for a quick cuppa, then![]()

that still makes my brain explode... don't understand it at all!

The size of the Planck length can be visualized as follows: if a particle or dot about 0.1mm in size (which is at or near the smallest the unaided human eye can see) were magnified in size to be as large as the observable universe, then inside that universe-sized "dot", the Planck length would be roughly the size of an actual 0.1mm dot. In other words, the universe is to a visible dot as a visible dot is to Planck length: The diameter of the observable universe is to within less than an order of magnitude, larger than a 0.1 millimeter object, roughly at or near the limits of the unaided human eye, by about the same factor (1031) as that 0.1mm object or dot is larger than the Planck length. More simply – on a logarithmic scale, a dot is halfway between the Planck length and the size of the observable universe.

After the 3rd post about stolen-gate I figured "sure, it's Tuesday, people might still have the Monday blues, they will understand their mistake and edit their posts".
But no, no they didn't. It only went on further! And we expect to leave this planet one day to make home elsewhere![]()

What a great post.
stolen from nasa surely
You cant even write 6 letter sentence properly, plus no one cares..
Amazing image... Thanks for stealing it for another forum... Derrrrppp.
Soundood's post clearly states he stole it for somewhere else, not from. The number of people misreading it is disturbing.

Yeah the amount of people who didn't read and are slating the guy is quite funny/sad![]()
