How do we know what happened during the first few seconds of the Big Bang?
In: Planetary Science
We don’t know, we don’t even know if there was in fact a Big Bang. But with what we know about Newtonian physics, relativity, and quantum physics, we can model what happened after the first few tiny fractions of a second and get to what we see in the universe now via computer simulations. However those first few Planck seconds there was too much heat and energy to accurately model that.
