This is a tutorial on how to calculate the number of things in the universe.
Michael from Vsauce calculated approximately how many things there are in our universe… the Observable universe (6.2 billion lightyears). Crazy, isn’t it? Here’s how this was achieved.
In Vsauce’s “Things video” he goes very in depth with facts and ways we could use to solve the equation. Since the video is quite hectic with facts, I’ll state where he’s getting at here. This is as simple as I could possibly do.
Michael (Vsauce)’s idea to solve this was very computic. He stated that in 1 Google years(100^10), our universe will run out of gases and will die down. Now you can notice some doors opening up. Here’s where you may have gotten lost. If you put all of space’s mass into human brains that just think, think, think unlimited thoughts from the start of life until life itself runs out in 1 Google years, how many thoughts would you get?
Thoughts are everything, Thinking about what you just read above is a thought and wanting to watch his video is also a thought. I searched that it takes about 4 seconds for the full thought to register in your brain, we could use this fact too. So with the human brains thinking until 1 Google years, it takes 4 seconds to process 1 thought. If the calculations are correct, the following will occur:
1.458 X 10^227
Yes, that is a scientific notation. Now if you solve this, you’d get the number of thoughts possible, which is a rather large number. Now you’re probably wondering, what about Dogs? Cats? Chairs? Well, to settle that we are safe to say we know how many elements there are, 10^183, which is:
1,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000, 000,000,000,000,000,000,000,000,000,000,000,000, 000,000,000,000,000,000,000,000,000,000,000,000,000, 000,000,000,000,000,000,000,000,000,000,000,000,000
You’re still probably wondering, “how does that equation count other living and nonliving things?” All things like chairs, tables, ect. are made of elements. The combination of the elements is a thought, that would be pursued and made.
Now, when you are to combine both equations of 10^183 and 1.458 x 10^227 you would get 1.458 x 10^227 + 10^80
That equation seems quite complex, but it’s very easy if you are to know at least a little bit of scientific notations. Since Vsauce didn’t solve this equation, I went ahead and did, and here’s your total.
145,800,000,000,000,000,000,000,000, 000,000,000,000,000,001,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000, 000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000, 000,000,000,000,000,000,000,000,000,000,000, 000,000,000,000,000,000,000,000,000
