Evidence for the Big Bang

• We can see the light just arriving now from it. That is what the cosmic background microwave radiation is.
• We can measure the expansion of the universe. Work backwards. Originally the universe must have been very small. Scientists say smaller than an atom.
• We can simulate events less than a second after the big bang in particle accelerators.
• We have math that explains it that is consistent with observations.
