I always have an question about the light speed.
From any observor who runs slower than light
speed, the light speed has a maximum number
(300,000km/s).

But based on the relativity theory, anything runs
in light speed, time dilation will become
infinitive large.

No. The Lorentz transforms cannot apply to anything that moves
at c. We cannot assume what time dilation is for a photon.

Which means if the observer is
light itself, it feel can reach any place without
time.

No. We cannot assume that. The photon responds to the medium
through which it passes, so it must be "aware" of change.

so size of the whole material universe for light
observor is zero!!

Again, no. The Lorentz transforms do not apply to anything that
moves at c.

and
the whole universe material is like tiny-little
bullet, pass light-observor in light speed.

No. Perhaps like penetrating a *** of paper...

Is't it like what we see light? If symantric works.....

Any idea? Thanks

Light simply doesn't care. It is its own anti-particle, so it
just as well could be observing us all getting younger... we just
perceive it backwards...
