solar time calculation
Is it logical to say that there is no such thing as time?
We humans over years have produced time based on Solar calculations. How do we know that there is a Space/Time continuum exactly. I always think this because history is only marked by man and nature, not preserved by the universe.
Einstein showed that time must, in some way, be a physical thing, because you can affect how fast you travel through it!
According to his theory, the closer you get to the speed of light, the slower your relative clock goes.
So in a spaceship traveling at 9/10 the speed of light, doing that for 20 years, you would age 20 years – but the people who were stationary, would age 46 years.
This has been observed in particle accelerators – they decay at a known rate, but when accelerated extremely fast, they last longer – of course they don’t actually last longer – relative to itself its still the same – but to us as stationary observers, we see it being a little longer, since its ‘clock’ is slow.
Also gravity affects time – so you’d age slower on earth than out in a low gravity field. This too is observed in the Global positioning that satnavs etc use – it needs to be recalculated and adjusted because the satellites’ clocks go a bit faster, and so when measuring our speed, they will be out on our position after a given period.
