So I want to know if these are true or false, if false why are they
A geodesic is a path between two points in spacetime that maximizes the invariant
distance ds2.
A massive particle's rest mass increases with velocity.
If I re a laser beam in the general direction of a black hole, there is no way I
will get hit by any of the light from my laser.
A 4-vector can be both perpendicular and parallel to itself.
For a massive particle with angular momentum L orbiting a point mass, the
corrections dues to general relativity always make the radius of a stable circular
orbit (assuming it exists) smaller than it would be in Newtonian gravity.
