Hi Jim, of course this time cannot be taken like a matter or a force or others, but in telling that it does not exist it is the same that we don t exist , this time is a thing wich is necessary for the universe , without time, we have no matter, no evolution, no motion, no interaction, it is a parameter different than the others but it exists, we have a past, a present and we shall have a future and it is due to time and its duration. The sciences community nver has told that this time was a force or others, we all perceive this time in our lifes, we are bornt, we live a time and we die like all biological creations, einstein has interpreted this time with observations and with the special relativity we know that it is a tool like we see our past more we observe far in space, like we see our sun 8 min in late, it is a tool this relativity permitting to observe and see an evolution in analysing our past , you see well that this time is a necessary piece for the universe and its motions, never we have told it was a force, but it exists , you exist and you have a time life like all , in our equations this time is taken seriously into account.
