At the very high energy densities after the big bang, these forces were unified. The first unification, the electroweak, occurs at lower energy densities, corresponding to a late time period after the big bang. At earlier times, the strong force is believed to unify with the electroweak force, and at still earlier times, all four forces, including gravity, were believed unified. So was gravity absent? Yes and no. All four forces were unified into one.

Yes. Since that is a place / time we can no longer visit, nor is it visible, pondering it is just for fun. > If one analyzed the words, "Space-Time" > closely, one might say that they can be > summarized, or paraphrased, as > "Existence," a "Substance of Existence," > or a "Substance." No. There is no indication that spacetime = either "substance" or existence". It is at best a "plastic" relationship between bits of matter and energy. > If the "Big Bang" happened, it happened > in some kind of existence. Sure.

Not at its current size. And no clear indication that it had existence prior to the Big Bang. So "always" has a denigrated meaning. Sanny pointed to a problem with a pre-existing spacetime...

What do you say? ----------------- curved motion is a net property of mass !! space has no properties except hosting mass !! just as simple as that ATB Y.Porat --------------------
