But there is only so much this light can reveal because there is an inherent barrier. The oldest light that we can detect comes 380,000 years after the Big Bang - Cosmic Microwave background, or CMB. We don’t have access to information about the universe any earlier than 380,000 years after the big bang. But light is not the only thing that can carry information. According to the latest cosmology models, there should be a gravitational wave background. This background would have occurred within the first second of the big bang so it would give us information that is almost as old as the big bang. It could reveal the secrets of creation. If you were in a house near the beach and the sea was calm, you could conclude that the wind must be gentle. If you saw the waves becoming bigger, you could conclude that somewhere the wind must have picked up, because a storm far away can form strong waves which can travel very far. So, the reason for the high waves could be a storm far away, or there could be some strong wind nearby. This is analogous to how it is with gravitational waves. We cannot feel the reason for the gravitational waves, but kn
