What would happen if you moved at the speed of light?

Omits

Well, the question seems to be a non starter!

Classical Motion

Even if you had the where with all and 1 year to achieve c, I don't think one could survive it without very heavy and firm shielding. Even though there are only a few particles in a cubic of space, at that speed those particles become a flux. It would shred your body structure.....and craft structure.

Imagine the flux if going 100 or 1000 c. These would be c collisions. Producing a huge flux of disintegrating, ionizing charge fragments.

Like standing in front of a CERN stream.

What is explained is closed systematic! Open systemic, you at '0'kps never approach the speed of light 'c' ((+)300,000kps |0| (-)300,000kps) closer than (+/-)300,000kps. It is a "go with" constant.

Also, according to the Heisenberg uncertainty principle if you know your velocity in the universe (in this case to exactitude) you can never know your position (in this case you'd be all over the map (in the dead center of Stephen Hawking's "Grand Central Station" of the universe, aka where Einstein landed in his mind's eye trip to the speed of light))!

This is a question where we get a reverse Dunning Kruger effect - it is beyond the region of physics that science really knows or understands and everything said ends up being essentially speculation.

What everyone does know is that mass dilation increases the effective mass of objects near the speed of light until at light an object's mass becomes infinite. (making that impossible) Similarly time dilation may slow the speed of time at the speed of light to zero. From the objects perspective as it accelerates it becomes infinitely fast.

A fairly obvious point is that the speed of light is an intersection point between the STL and FTL realms of speed. Another obvious point is that light itself does have mass though zero rest mass.

If the mass of a massed object could somehow be balanced to zero then it could move at the speed of light. In fact it would immediately accelerate to the speed of light - for 'free'. There are two basic hypothetical approaches to balancing mass to zero - either adding something with negative mass or creating some kind of 'shield' that hides the mass. Curiously if we could create one a real Schrodinger box would be a possible way of achieving the second.

So maybe not completely absolutely impossible after all.

Some (not me except in picturing) have already been there, done that, in the math. The total mass matter and energy of the universe equals zero. Truly bothered those who came up with reduction to zero (0-point) until Stephen Hawking told them not to let it bother them. He told them the universe is always there (at the 0-point of infinity (the zeroing point of the infinities -- the infinities remaining though not locally, relatively, finitely)).

Worked that out myself once. Realized that with neg mass we could have a universe with a zero net mass. Never had or found a way to prove it or test it though.

Dark matter could be neg mass maybe - would be fascinating..

Questioner

At the speed of light one's mass becomes infinite,
but is that mass symmetric or only in the direction of travel?
Otherwise one would turn into an actual black hole at the speed of light.
All light would be photon sized black holes.

What would happen if you moved at the speed of light? Well, you can't.
