## Main Question or Discussion Point

Suppose for the sake of argument someone said the outward speed of light is infinite and the return speed is c/2, creating a two-way speed of c.

Wouldn't this violate the conservation of momentum?

p = E/c. That means on the way out, the momentum of light would be zero, but on the way back it would be very much non-zero. Shouldn't the momentum be the same both ways if we're to have conservation of momentum?

Any insight at any level is welcomed. Thanks.
