Why is this rubbish rubbish ? :-)= .. Simplistic: This doesn't deal with the great Godel's treatment, but shows the basic 'contract to zero or expand to infinity at light-speed" expression. The basic term which appears in mass time or space variation with change in velocity is k =3D (1-V^2/C^2) V=3D velocity. C =3D speed of light. This appears in the denominator for mass variation (asymptotes to infinity at V=3DC) and in the numerator for distance and time (asymptotes to zero at V=3DC) At V=3D 0.1C k is only (1-0.1^2/1) =3D 0.99 and 1/k =3D 1.0101... ir At 0.1 x light speed mass increases by ~=3D 1% and time and distance contract to about 99% of original. It starts "to get out of hand" as V rises. As can be seen in the table below - you have to get VERY near light speed before the photons start to huddle at anything like a point source :-). eg travelling from Alpha Centauri at 0.999999 of light speed the distance contracts from about 4 light years to about 4/500,000 ly ~~=3D 4 light minutes (and/or the object would see a trip time of 4 minutes). Making the extra ":small" increase of 0.000001 of light speed so as to travel AT light speed increases the energy required to "infinite" for all except particle with zero rest mass, AND for zero rest mass particles (which MUST ALWAYS travel AT light speed) brings distance and time to zero - until the end of all things. (At least). (Probably).
