The theory of relativity makes sense but still doesnt explain why lightspeed is the limit. Thoughts please...thank you..
The answer is really quite simple.
In all known cases, information cannot travel through space faster than the speed of light. Exactly what establishes the speed of light is one hell
of a good question - but likely contained within the answer to what, exactly, gravity is.
Take the time to consider gravity, for a moment. It is a very mysterious phenomena, and highly unique among all fundamental forces. Gravity has no
polarity, continues to a theoretical infinitum, and is orders of magnitude weaker than the other forces - but exhibited by everything known to have
mass. Many even question whether we can consider it a force in the classical sense, but rather it is some sort of underlying entropic principle of
In either case - the implications of Relativity are absolutely phenomenal. For starters - the name is a misnomer. Nothing CAN be relative according
to relativity - space, itself, is a constant frame of reference as established by the following:
No information can be shared between two points faster than the speed of light allows, at least via any known mechanisms. Since changes in the
location and status of a body amount to information - it stands to reason that the effects of gravity are also limited to the same speed that light
travels (it may, in fact, be that 'gravity' -whatever it is- sets the speed for light). Let's take a trip back to gradeschool science, and
consider why objects will sound higher-pitched when coming towards you, and lower-pitched when going away. This is called the Doppler Effect. Since
the speed of gravity is limited, it would stand to reason that an object in motion would begin to 'ride' the 'G-wave' of its own mass.
This is why mass appears to increase from other frames of reference when an object is accelerating. Once more - it explains the time dilation of
near-C velocities and sets up the speed limit known as the speed of light. What it also does is make all velocities non-relative.
Consider - one object moving at 0.8C in one direction, and another object moving at 0.6C in the opposite direction. The two collide at a relative
velocity of 1.4C - which doesn't break the universe and spawn another big-bang - because the two objects have an absolute velocity established by
space, itself. While one could make arguments about space moving - it is really immaterial to known physics whether or not space, itself, is moving -
the physics remain the same even if this universe is hurtling through some other space at "impossible" velocities.
Of course - I think we look too much at the physical universe and overlook the more simple way of analyzing the universe - which is just to consider
the universe and the physics involved to be data and data processing. We get a little too consumed with particles and waves and simply overlook the
idea that everything is a functional means to some other end. Missing the forest for the trees, as one could say.
