Albert Einstein created the General Theory of Relativity to explain and mathematically model gravity. As he was finishing it, he had an oh-shit moment and realized it wouldn’t balance out properly unless he shoved in an arbitrary number that he called the Cosmological Constant. Without this number, his theory would show that the universe was expanding instead of being static. Years later, physical evidence was obtained that the universe was, indeed, expanding. This evidence was the “red shift” – the color shift towards the red of the returning radiation from distant stars in comparison to closer stars. This shift is due to the Doppler Effect. This is the same effect that causes an ambulance’s siren to sound differently to us when it is coming at us than when it is traveling away from us. Eventually, Einstein acknowledged his mistake and removed the constant. The funny thing about this is that he was originally right, but then a simple assumption of the way the world worked did him in. Continue reading
Nature is a whore. It likes to spread itself all around until it’s been everywhere. Most everything in nature seeks a balance, a point where it is evenly distributed. The greater the disequilibrium, the more it tries to even the score.
The water on the Earth is constantly seeking a common level. This causes the formation of rivers and streams to channel the water from high to low. The more water there is upstream, the more the rivers will flow. Electrons seek a common level as well. Whenever there is a pool of electrons, you can be sure that they are trying to disperse themselves and when they do, you get an electric current. The more electrons you have in one spot, the greater the electric current will be when they disperse. Heat is the same way, constantly trying to even itself out. The greater the source of heat, the quicker the heat will transfer itself to somewhere colder. Continue reading
I’m sure most of you are aware that we live in a world with three standard dimensions – length, width, and height (or X, Y, and Z if you are a mathlete.) Less of you are probably aware that there is also a fourth dimension. No, it isn’t a wormhole in your clothes dryer in which socks escape from our reality. It’s much simpler than that. The fourth dimension is time. Time is a funny one because it relentlessly progresses in one direction. Lots of scientists say you can slow it down by traveling really fast – much faster than even I drive on the highway – close to the speed of light fast. But none of them has figured out a way to make it go backwards, though. Thank Bob for that one! I’d probably end up spending most of my days going back in time and slapping myself silly for something dumb I was about to do, and that would get tiresome for all of me. Continue reading
