- The Big Bang Theory contains some really wild assumptions. To start with the theory maintains that we all started from “nothing”. For this assumption to be true there must have been equal amounts of matter and anti-matter created. Even energy and anti-energy must have started in the beginning. So, if you add up the whole Universe again you get zero, “Nothing”. Now that is a big assumption.
- We have a lot of evidence that the Universe is made of matter. It is everything, nearly everything. In the laboratory and in hospitals we have evidence that anti-matter can be created. We have evidence that when matter and anti-matter come back together they create a burst of Gamma Rays. Radiation. Mass back to energy. But, there is no anti-energy that we are away off being created at the same time.
- Anti-matter was first discovered mathematically. It was needed to balance physicists equation of atomic behavior. We finally created some evidence in the laboratory in 1935 when we discovered the anti-electron. Anti-electrons ( also called positrons) are exactly the same as electrons except the charge is reversed, it is positive rather than negative. Again, the Big Bang assumption is that creation had to have equal amounts of positive and negative charges in order to come from nothing.
- All the particles since discovered appear to have an equal and opposite twin. Protons have anti-protons. Quarks have anti-quarks. Even the element hydrogen as a twin anti-hydrogen that is produced in the laboratory. Except for the opposite charges we can not tell the twins apart. A galaxy made of entirely anti-matter would look to us to be exactly the same as a galaxy made entirely of matter. Unless, somehow you get the two together. If you landed one of our spaceships on the anti-planet in this galaxy you would go pwooooof! A burst of Gamma Rays is the evidence you get that that galaxy was made entirely of anti-matter.
- Weird as it is anti-matter is being used in our daily lives. Anti-electrons, or positrons, are the “P” that is in PET Scans. Positron Emission Tomography, PET, they did not want to call it anti-matter for fear it would scare people. Would you lower your body into an anti-matter machine. I don’t think so.
- The biggest mystery in physics is why do we live in a matter world and what happened to all that anti-matter that surely was created in the beginning? We know that the center of our Milky Way Galaxy is still producing anti-matter. We know because when an electron and an anti-electron come together they produce a unique signal of Gamma Ray energy. The signal is exactly as calculated using E = mc^2.
- An electron and an anti-electron have the same mass. 1.822*10^-24 kilograms is the combined mass of the two of them. c^2 = 9*10^16 meters^2/second^2 . m*c^2 = 1,020,000 electron volts. The two Gamma Ray bursts jetting away from the electron / anti-electron annihilation in the opposite directions is exactly 510,00 electron volts. An that is what we measure when we point our detectors at the center of our Galaxy.
