Time Travel and Light Speed
Been a busy time of life for me; going to use a past post about science for this week.
Going to post something a little different from talking about remote careers; today like to talk about space.
I am not a physicist–and the mathematics of physics gets me lost–I do not understand the math.
I enjoy physics from an amateur (or lay-person) viewpoint. I enjoy learning about physics ideas that are believed to be true–but do not seem to make sense from my common sense perspective.
Time Travel is possible for the Future
One idea is dealing with time; from my personal experience, time travels into the future is impossible. Time goes at a steady pace in the future; the clocks go at the same speed. You may read about time travel in the world of fiction, but in the world of reality – time is consistently going at the same rate in the future. No matter what you are doing – the time clock moves simultaneously into the future.
So, when I hear science mention that time can travel at different rates in the future, this does not fit my common-sense observation of what I see–and it is one feature of physics that I enjoy.
Time can travel at different rates in the future when traveling at light speed (or come close to it).
Strange things can happen when a person can travel at light speed.
As I understand it, time can travel at different rates of speed going into the future. You cannot go back in time, but can travel into the future at varying rates of speed. If I understand it and the physics is correct, you can build a time machine going into the future but not the past.
(Not sure of the specifics dealing with the math; give an example to express an idea)
If you are traveling in a ship at light speed, you may believe that you were traveling for one day, while people on planet Earth would think that you were traveling for several years. Time travels at a slower speed inside the spacecraft than outside the spacecraft.
Time can travel at different rates into the future when going at light speed (or close to it).
One place on the Internet that explains this is from a science show called Cosmos by Carl Sagan. (It was a science program done in the 1980s).
YouTube has a video about this; you can find it at:

Sometimes fact is stranger than fiction. I hope people enjoy it.
