Minkowski's four dimentional universe?
Is it real.Can we prove that the 4th dimention is the time.Is it a variable?
According to the special theory of relativity it is but this theoy isn't
prooved.Suggest how to prove this.

What do you mean by "isn't prooved [sic]"? The Special Theory agrees with
observations (that do not invoke gravity).

I didn't include gravitation but curved space-time which is a part of the
special theory of relativitty

So, what part of Special Relativety is not supported ("proven") by
observations?

According to Michio Kaku's book Hyperspace, the exact number of
dimensions is ten.

time is a 4th dimension of universe, Einstein proved this, Stephen Hawking
didn't .

Time as a dimension goes way back before Einstein.

Isn't whether time is considered a "dimension" or not simply a question
of definitions?

A "dimension" is a quantity in which something (anything) is measured -
at least to physicists. What it comes down to, though, is that when someone
says that the universe is "four dimensional", THEY should say what they mean,
so yes, it is very much involved with definitions.
