Time as the fourth dimension?




In the book, 'Been there Before', Randhir Singh explains how time is the fourth dimension of space, and how his studies on wormholes can actually help explain this. Dr Sudeep, a renowned neurologist, had read about the 'Time is the Fourth Dimension' concept when he studied the Subconscious Brain in the past. But he wondered how all this could actually be possible at all!

The location of anything we see can be explained easily by knowing three dimensions....its position relative to the x, y and z axes.... that is length, breadth and depth.... why should there be a concept of the fourth dimension at all?

The photo above is of a galaxy and gases surrounding a black hole 10 billion light years away....

Therein lies the answer.... We know in which direction the galaxy is..... it can be easily seen is it not?

Wrong! We don't know in which direction it is, but we know which direction it was 10 billion years back..... Light has taken much time to reach here.... We don't know where the galaxy is now... we can only say it was in this position along the x, y and z axes at a particular time 't'.

Although many scientists now believe otherwise, we now realize what a genius Einstein must had been to think out of the box... his concept of space-time as such a simple logic, founded the base of astrophysics.... it also stresses how less we know about our surroundings...

It also makes us realise that he small we all actually are.
