Lorentz-Four-Contractions, Session 7, Part 2

The equation that I ended with in Course 3, Session 7, Part 1 would give you a fraction of the terrestrial time for speeds that are equal to or under light speed. So, if t=.2, this means that two arbitrary seconds would happen in your ship while 10 seconds wold happen down on earth. This is why if a ship were to travel at virtually light speed for only a brief while, let's arbitrarily say for half an hour, it could come back down to earth and a million years could have elapsed for those down on earth.


The length of an object is based on its relative motion too. This is because length is a parameter of an object's size, and size appertains to the stuff that an object is and everything physical is energy and thence motion. As stated, all motion is relative to light. Thus, every physical parameter exists with a relative length whose size or amplitude varies as the given physical phenomenon changes in motion relative to the action of light. Motion always happens with a velocity -- a speed in a direction. Relative motion always involves relative velocity. So, when an object changes in velocity, its relativity to light varies, and thus, the size or amplitude of at least one parameter of the moving object must change. The change in the length of the parameter that is in the mainstay of motion is based on the same idea as to how time is altered. This is: L=(1-(v^2/c^2))^.5. This is in terms of an observer standing still. This is always less than one for speeds equal or less than light speed. So, if an object is traveling close to the speed of light, it will appear to have very little thickness to a terrestrial observer. Time for anything happening always exists for at least one framework of observation, and length for any object always exists for at least one framework of observation, yet the ways in which those parameters appear to those watching may indicate that those parameters disappeared, even though those always exist for one reference frame or another. Certain parameters always exist according to more than one reference frame -- whether or not they exist to an individual may depend on their reference frame, which includes their field oscillation and their relative velocity.
