Near the Big Bang, densities and energies were extreme, warping spacetime. Relativity predicts time passed differently under these conditions. This affects how we interpret signals like the CMB or distant supernovae. Understanding time dilation helps model early-universe events accurately. It connects general relativity with cosmology. Without considering it, age estimates and expansion rates would be off.
Time dilation is crucial for interpreting early-universe observations.
It also links Einstein’s theories to practical cosmological measurements.
Time flowed differently near the Big Bang due to extreme densities.
