Cramer’s Special (Education) Theory of Gravity

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
