In my last post, I went over the conditions Dr.'s Tyson and Goldsmith showed were present at the beginning of the universe including the size, time, and temperature. To understand even a bit more of what happened, Tyson and Goldsmith refer us to one of the most famous equations known around the world. E=mc^2. "E = mc^2-- energy equals mass times the square of the speed of light-- gives us a supremely powerful computational tool..." (Tyson and Goldsmith 36)

What's in the top-right corner isn't part of the work |
This equation was declared in 1923 in Albert Einsteins'
The Principle of Relativity (which is cited in this book, I would like to point out) This equation allows us to calculate things impossible to see with the naked eye, such as radiation and photons(particles of visible light, you decide if you want to qualify it as visible or invisible). Luckily, there isn't a lot of energy in these particles of light, and we aren't compatible with the equation, Tyson and Goldsmith give a very... imaginative description of what were to happen if we were, "Start hanging around gamma-ray photons that have some real energy---at least 200,000 times more than visible photons. You'll get sick and die of cancer...As you watch, you'll also see matter-antimatter pairs of electrons collide, annihilating each other and creating gamma-ray photons...Increase by a factor of 2,000, and now you have enough energy to turn susceptible people into the Hulk."(Tyson and Goldsmith 37)

If I'm gonna give him credit, might as well include a picture of the genius himself right? |
As with high school physics, the knowledge of the formula is the easy part, I commend all the physicists out there who take time out of their day to apply these formulas to our world. The idea to work deciphering the theory and equations like it sounds appealing to me. Have you ever heard of the theory of relativity before this and if so, what did you think of it?

Very informational. This post really encompasses the overall gist of science and shows how this information can also be used in computer science. The theory of relativity is very intriguing and is a concept I spend a lot of my time pondering about.
