Salute to Spock with Antimatter
I was walking home the other day and started thinking about the origin of the universe and the Big Bang Theory. Scientists tell us that the universe and all the planets, stars, moons, comets, asteroids, and other star stuff was created in one massive explosion approximately 14.5 billion years ago. Our solar system appears to be a little newer at 4.5 billion years old. According to science, the universe PRIOR to the Big Bang became denser (particles moving closer together) and hotter. As these high energy particles were forced closer and closer a nuclear explosion occurred and the universe immediately went into reverse and started expanding. Many scientists, including Stephen Hawking, say that the Big Bang represents the beginning of time.
The most fascinating part of the theory is to consider that if space and time are inextricable and that the Big Bang required space, there must of course had been time before the explosion. Some scientists have theorized that the universe before the Big Bang contained antimatter. Antimatter can be thought of as an exact opposite to our current matter. Imagine protons instead of positive charges having a negative one and imagine electrons instead of a negative charge, having a positive one. An atom of hydrogen would have the same weight but instead of one negative electron and one positive proton, it would be the opposite.
Some have even suggested that you and I existed in the pre-Big Bang universe as an exact copy of ourselves yet opposite! Mind bending stuff. What is known is when antimatter and matter meet, they annihilate each other and release a significant amount of energy. While I am far from being a Trekkie, I do know that the Enterprise was powered on antimatter.
It gets you thinking when you consider that perhaps time always existed and perhaps our doppelganger existed in the universe before this one over 14.5 billion years ago.
What really boggles my mind is to consider the theory that the universe has always and will always cycle between Big Bangs and Big Crunches (universe contracting). If the Law of Conservation of Mass holds up in any state of the universe then we are all made up of the same amount of star stuff (atoms) at any given time and in any given space. Assuming the four fundamental forces remain in an antimatter universe then maybe our opposite doppelganger did exist and will always exist! Whoa! Maybe deja vu is more real than we give it credit.
