That CAN'T be true! / Re: How can time be a dimension?
« on: 18/10/2016 02:28:31 »
I am a layman in the topic, but have considered and read up on it over the several years.
My informed opinion is that time is the rate of change, movement, of energy and/or forms of energy relative to space. A unit of time being some form and amount of energy moving from here to somewhere else: Some amount of sand falling in a tapered glass container is "one hour."; The sun showing up at the same spot in the sky each day is "one day."
Time is not a fundamental aspect of the universe, but instead is an outcome of the interaction of energy with space.
The idea that time is a dimension has always struck me as suspect. If I go fast enough my length dimension will change according to an outside observer, as will my time--One year passes for me, while 100 passes for him. However, when I return home and stop, my length, according to the same outside observer, will be restored, while my time will not. That is, according to the observer our clocks will again tick at the same rate, but the alteration in my time, because of my trip, will not be restored--I will still be about 100 years younger than him.
Then it follows, for me at least, that the idea of "space-time" is highly suspect, as time is only apparent from the interaction of energy with space. If two people agree to meet at the local mall tomorrow, and then one goes on a very high speed spaceship ride. The result will be that the non-traveler will be at the mall in their tomorrow, while the traveler will show in his tomorrow; They will miss each other. Their space dimensions will be correct, but their time "dimension" will be incorrect.
