There cannot be a physical value given to infinity, and it is not possible for something to be physically infinite. It is scientifically believed that the the universe has gone through an infinite cycle in the past and for the future, despite there being no chance for something to physically be infinite (aka like temporal past). Science is flawed in assuming the universe is infinite, and that the universe was able to come from nothing. Those are two individual flaws, one of which violates the first law of thermodynamics.
