You cannot say the universe just suggested time for itself.
I'm not saying that. I'm saying that it is in the nature of the universe to change. However, this change may have a starting point.
From the beginning of the universe there was time.
I would say that from the beginning of time there was time.
The movement of celestial bodies provides the experience of time.
Change in everything relative to each other does. It's not just about celestial bodies. I don't know why you are talking about celestial bodies.
We can only calculate 'time' by the movement of celestial bodies.
I'd like to introduce you to a recent invention called a "clock".
You can't say that from the beginning of the universe there was no passage of time because if we can measure time by the movement of celestial bodies now, then before time--time could still be measured the same way.
I'm not saying that. First, I don't believe in a "beginning of the universe" -- there is only the beginning of the universe's change.
Second, I don't know why you are talking about "no passage of time" from the beginning of the universe. I'm not saying that there was no passage of time after the Big Bang, if that is what you mean.
There is nothing that suggests that at one time nothing moved because if nothing moved then it would be physically impossible for it to start moving.
Of course there was no
time when nothing moved, because time would not have existed at that point. Time started in motion/change, not in changelessness.
There has always been movement in the universe; and since there has always been movement in the universe then time has always been.
I totally agree. Time has always been, since in all times there has been time! However, nothing in what you just wrote means that time didn't have a beginning.
If there is no outside of the universe then how could it expand.
Expansion refers to the increase of distances between entities. It's not expansion in the mundane sense.
You know very well by physics, does something expand and contract. If the universe has nothing to expand into then the expansion would be contained.
You should read the physics. It's not what you might expect.
Like I said in previous posts nothing cannot exist
You are absolutely right. Nothing, by definition, is not something, and therefore does not exist. However, it may be the case that no unicorns exist. This doesn't mean that the "nonexistence of unicorns" exists, but that there simply are no unicorns that do exist.
In other words, how can a universe expand if it has nothing to expand into.
Once you change your paradigm to a relativistic one, you'll see.
You can deny this truth but it is the Truth.
I can deny this falsehood very easily.
