Do physicists think time exists?

It’s a trivial question to ask what time it is, but far less trivial to ask what time IS. You might even be surprised to learn that not all physicists believe time even exists. Brian Greene briefly explains more.

time orders your decisions into a string, which could look like one distance between one root and one leaf of a tree. every leaf on that tree represents you, making a different decision at a different time or a different location, always drifting away slightly from all your other selfs. you are only able to see your past as a linear time line, but in reality all possible paths you could ever walk happend, creating that whole tree. humanity as a race is defined as multiple beings that walked one evolutionary path and created even more "leafs" of itself we all have the same roots. We are connected like space and time are connected with velocity and temperature and those are connected with etc. and ect. (we may not know yet). every cause is also an effect. A theorie of everthing does not need one formular, with a clean consciousness you are able to "see" feel that net and develop a good intuition for what is called karma. why is it so hard to make people belief in things like collective thinking? why be so egoistic? there is no such thing as a originator there is just a person that acts as a medium to let everyone understand what before only a small part of the whole collective knew. the only reason i could think of is that everybody should have the possibility to get that understanding of life by themselfs. sry for the spoilers but you'd flame and hate me anyway as long as you haven't had the same conclusions i have :D

Time is synchronized numbers for all dimensions in which Pythagoras theorem holds true.

Would it be fair to say that physicists don't really understand what time is in the way that Newton didn't really understand what gravity is back in his day? I understand that the fundamental laws of physics are symmetric with respect to time and I get that this says more about the laws of physics (implies conservation of energy, for instance) than it does about time itself, but aren't there some clues there? If time is not an illusion (and I'm not convinced that it isn't), then there must be something about the laws of physics that gives clues about what time really is.
