Today there’s a new announcement about new data recorded at a telescope in the south pole. A study of the radiation over the course of 9 years, 9 freakn’ years has resulted in a pattern emerging in the background radiation of our universe. This pattern infers gravity waves, a direct result of the math Einstein used to explain gravity.
Not related to E=mc^2, relativity is used every day to figure out where your cell phone is. GPS requires a very precise clock to compare signals traveling at the speed of light from a satellite to a matching pattern in your phone. Depending on where the patterns match up determines where you are on the planet. As civilians we’re not allowed to use devices as accurate as those used by the military. Otherwise, you’d be able to locate your cellphone hidden under a ball cap in the corner of your living room next to a marble.
From the wiki page the satellites need to transmit on an ever so slightly slower frequency; 10.22999999543mhz compared to the receiver on land at 10.23mhz. That small difference in frequency is to compensate for relativity. If that adjustment wasn’t made, GPS simply wouldn’t work. That same calculation can be applied to many more things other than GPS, like gravity waves being propagated by the big bang. The number didn’t come about by guessing. That number was determined by a physicist before the satellite went up.
The significance of the evidence by the telescope is huge. The math predicted that there should be something observable in the form of gravity waves in the microwave background noise of space. If this background noise didn’t exhibit this property then the big bang theory would need to be tossed out and a new theory would have to replace it. However, the prediction found supporting evidence.
This is cool, the math behind it is cool. The prediction is amazing, and the evidence found to support the prediction took a long time to record. I almost feel bad that the evidence was found to match so well. This means the other theories are losing to the big bang leaving fewer options with supporting evidence.
