The existance of time as anything other than a mere "concept"

Hello everyone,

I would like to start a discussion with the forum members related to
the concept of time, and it's existance as anything other than a mere
concept.

I believe that time is merely a "concept" that we use as a tool, to
compare the occurrence of events. For example, the earth orbits the
sun, and we call this one year, the earth makes one revolution on it's
axis and we call this a day. A machine called a clock causes an arm to
rotate 360 degrees at a certain constant rate, and we call this a
minute or an hour.

With time, it seems all we are doing is taking the passage of one
event, (i.e., Earth orbit, clock-arm rotation, the rate at which a
Cesium atom cycles or absorbs and releases energy, etc.) and then
comparing it to another event, (i.e., the length of a workday, the
speed of your car, how long it takes to cook your dinner etc.. We are
just using the "concept" of time as a tool. We use the passage of one
event as a reference point, and compare other events to it.

In my mind, when people talk about "time travel" there is really
nothing to travel back into, or to travel forward into, since time is
only a concept. Likewise, when people talk about an object like a
planet warping "space-time", again, I don't see how time, i.e.,
something that exists only as a concept, can be "warped" or manipulated
in a physical way.

In physics, is time considered a physical entity that is moving, and/or
something that can be moved through ? Is time travel considered
possible, and is time considered to be a dimension and/or physical
entity ?

Has anyone ever proven that time is anything other than a concept? Has
it been proven that time is indeed a "dimension" or even something that
has some form of energy?

I do not think it is even possible to "prove" that time exists as
anything other than a concept within our minds.

Time appears to be nothing more than that which separates events, based
on our own time reference measures.

I would appreciate other viewpoints and feedback on this topic.

Thanks
John
