LIGHT SPEED/LIGHT TIME light moves at 300 000 kilometres a second
light speed is a constant of universal time, and possibly straight line action time, and when used with planck's constant, newton's gravity, axiom 1, axiom 2 and axiom 3, light speed can be used with confidence to explain and understand most of our experience of reality
example 1 the planet mars is 227939100 kilometres from earth travelling at light speed it would take 12 minutes to go from the earth to mars example 2 the gathering place is 50 light years away travelling at one third of light speed it would take 150 years to get there
