Time travel

Is apparently possible via Einsteins equations.  The general theory is that since both matter and energy can create a gravitational field. This means that the energy of a light beam can produce a gravitational field. 

Basically that means that you could in theory create a moment in time, and from that moment you could always come back to that time.  Never any further back.  Of course this would mean that if there happened to exist another civilization that had also made their own time travel machine, you could ask them to borrow theirs, go back to as far back as they made it.

Granted time travel is a subject that I don't think about often.  More so because the future is full of wonder.  It's such a fun gift of wonder that I often ponder it.  It's noticeable how you start to change as you age but certain childlike desires still burn bright.  Mine happens to be science.  I don't particularity have a subject that I must enjoy since they are all so intertwined.

Although other than programming, I haven't touched much of it in a while, not to say I wont in the future though.  I generally tend to gravitate twords it, its mass of intrigue is so large, the pull is irresistible.

There is a sort of pleasure that comes from solving a problem.  I still can recall back in differential equations reaching a point in the book where my professor proudly states that he was the one that came up with that equation.  I don't remember the specifics but it had to do with the vibrations of a tension cable on a bridge.  Either way it was fascinating seeing his work in theory and in practice.  Still pondering what it must be like to invent a method to solve a problem that helps advance the most exact science, mathematics.
