Is time universal or does it exist only in the presence of matter?

Just food for thought. As human beings, we naturally assume that time is separate from matter and goes on forever in both directions. We base this assumption on the observation that matter has moved and changed since the big bang, and for it to have moved there would need to be time. But what about before the big bang? Did time exist then? Most people assume that time has always existed before the big bang and it was only a random factor that the big bang happened when it did. But not necessarily. According to Einstein's Theory of Relativity, we know that time and space are relative of each other. And while they can be measured separately, we should never loose sight of the relationship between the two. What does this have to with time before the big bang? Well the theory also states that time will speed up near areas with lots gravity, and time will slow down in emptier places with little gravity. What does that mean for us? That means that if we're in a place with absolutely no gravity, then likewise, there should be no time either (i.e. before the big bang). And it makes sense too. This way of approaching the Universe allows us to understand why it started when it did and not trillions of years before or a single second after. Time exists only relative of matter, and matter only relative of time. There's no universal time line for events to sit on. Things only happen in relative time to one other. The big bang happened when it did because time didn't exist until after it happened. To go back to the main question, "Is time universal or does it exist only in the presence of matter?" We can now say that we know why it only exists relative of matter. We don't need to rely on supernatural answers for a very a natural question.

  • TL;DR I'll just say this. Time and space exist within the universe rather than the universe existing within time and space.

  • Spacetime may not even be fundamental.

        Time and space are intertwined, as are matter and energy. Two faces of the same thing. Just like the duality of particles and waves, they are both. All 4 (spacetime and matter/enegery) are required for there to be a what, a where, a when, and an event. If you have space, matter and energy, but no time. Nothing can happen. If you have time, matter and energy, but no space. There is no place for anything to happen. If you have space and time, only matter but no energy. Then there is nothing to cause the matter to do anything. If you have space and time, only energy but no matter. There is nothing for the energy to effect and at light speed, time has no relevance.

      • Time exists wherever there is existence. Hence [i]spacetime[/i].

        • If what we consider as time is relative to matter and gravity; if there is no matter then I'd assume there would be no gravity too, so therefore no time. So it can't be universal, unless matter and by extension gravity are universal as well. But I have no idea what I'm talking about.
