What does «Big Bang» mean in Spanish?
- The Big Bang is an important aspect of the theoretical model of the universe. The Big Bang means that essentially the universe began at Planck time, 10^-43 seconds, from a single point some 13.7 billion years ago, expanding at great speed to its present state. Prior to Planck's Time, the Four Forces, strong, electromagnetic, weak and gravity, were united into a single force. At 10^-35 seconds, the temperature of the Universe reached 102^7 to 10^28K and the initial inflation of the Universe ended at 10^-33 seconds. The Universe continued to expand and its temperature dropped to approximately T=10^13 K until 0.0001 seconds after the Big Bang. The antiprotons and protons each annihilated. For some reason, apparently most of the antimatter was annihilated but there were surviving protons and neutrons. There were also a large number of photons per proton and neutron.
