The idea that you cannot exceed the speed of light is a religious issue in modern science. Special relativity (SR) accounts for clock discrepancies by assuming relativistic mass increases as relativistic distance decreases. This leads many book and professors teaching that these are real effects and Newtons laws do not work for space travel. The fact is they they are relative effects and traveler need not account for any mass increase of distance decrease, the two effects cancel out completely if you ignore both. NASA, if fact, does most of it's calculations using good old NewtonsLaws. Consider this a thought experiment.

In the year 3000 the Newtonian Church, Einsteinian Church and The United Church of All Scientists pooled their resources for a two year round trip to Ary 100 light years away. Each group calculated the fuel requirements and they agreed so they went ahead with the trip. Each had a separate compartment as the newts and the einies didn't want to talk to each other and nobody wanted to talk to the unies because they could not spell.

The einies say they cover almost 99% of the distance to Ary early in the trip, but the last light year seems insurmountable as they get heavier and heavier.

The newts don't believe they are really 99% of the way just because it appears so big and bright. They expect that is appears that way just because they at intercepting more light by traveling toward it so rapidly.


The einies used the blue shift of light from Ary to determine their speed ignoring the fact that the distance to Ary was very rapidly decreasing to about one light year away as determined by luminosity (red shift adjusted). Their progress toward getting there was hampered though but they reasoned the ship must have gotten very heavy as the rate of acceleration calculated by decreasing distance to Ary was also decreasing very rapidly. The acceleration they feel, however, doesn't change because they must be heavier themselves. They calculate their average speed to be very close to the speed of light and the total distance traveled just over a light year.

The newts kept track of the progress using distance = 1/2 acceleration squared times the time and check it by fuel consumed just to be sure. They calculate their average speed to be 100c per year and travel 100 light years in one year.

When they get home it is the year there 3202 and the unies reception committee is just arriving to greet them, about half of the expected einie committee is hanging around as they all had different round off error in their calculators as to exactly when the travelers would be back. The newt committee had waited and waited 200 years earlier and gave up and went home.

The eineis laughed at the newts, "You guys are always late====" ====

The newts laughed back, "Yeah but at least we have no silly speed limit and our calculations are much simpler and make much more common sense. If others think we are late that is their problem."

They both asked the unies how they knew exactly when the travelers would be back. The unies replied, "Newtonians taught us about absolute movement, Einsteinians taught us how time and space are related, we put those together with the Scarvarian quantum event time space model to make our TOE. We didn't need any fancy calculationd, we know you would travel two years in absolute event time orderings and about 200 years through relative event time orderings (space) and get back here in almost exactly 202 years relative to us."

The eineis and the newts laughed hysterically, "What do they know, they can't even spell. They only need a simple theory like that because they are so lousy at doing calculations."


How fast you think you are going depends on what measures you use. The ruler you use for speed is arbitrary and proper speed can easily be mapped to relativistic speed without violating any theory.


The exact time lapse for speeds not so close to c must be adjusted a factor involving gamma. It is interesting that gamma maps the infinate to the finate, confirming again, FiniteNature.


The relationship between classical acceleration, a0 and relativistic acceleration is given by: a=a0*(1-v^2/c^2)^(3/2) Relativistic acceleration goes to 0 as you approach the speed of light while classical accelleration remains constant.

Sometimes they call classical acceleration "intrinsic acceleration" as in http://kestrel.nmt.edu/~raymond/classes/ph13xbook/node59.html

Sometimes they call classical velocity "rapidity" as in http://math.ucr.edu/home/baez/physics/Relativity/SR/acceleration.html

http://www.umsl.edu/~fraundor/a1toc.html appears to be a good resource showing the validity of classical laws of motion with respect to the traveller.

Force and energy are the same for both the classical and SR traveller. Acceleromenters measure force. A constant force of acceleration or constant "intrinsic acceleration" is NOT the same as acceleration in SR. In SR EVERYTHING is relative. Classical mechanics are consistant with absolute phenomonon.


By Gamma? So everything has to be shifted by gamma? what exactly is the formula? I'm blanking on gamma and the formula at the moment. Could someone whose brain is awake put this down for those of use getting 'server busy' at the moment? ;)

gamma = 1/sqrt(1-v^2/c^2)

Or, gamma equals one over the square root of the quantity one minus the relative velocity squared over the speed of light squared.

Ah, thanks. So at light speed, Gamma is infinite or unstated/unknowable ( 1/0 ) and at absolute 0 (no movement whatsoever), the gamma is 1 ( 1 / 1 )? So Gamma is the absolute clock? ;-) Just teasing, but it does seem the formula pick absolute 0 as the reference point, and of course, any absolute zero would have the fastest factor of time, as it isn't moving. If I'm thinking right at the moment. I'm sure the Carver will correct me eventually though. ;-) ---StarPilot
