it slows down
That, is what would be time traveling.
The speed changes. (and sometimes the angle.)
It is called the Doppler Effect. When the source of waves approaches you (can be any type of waves - mechanical, electromagnetic like light etc.), the wavelength gets smaller and frequency higher. So when a car approaches you, you hear higher tone than when it departs.
The speed of a mechanical wave depends on the mechanical properties of the medium. When the mechanical properties of the medium change, the speed of the mechanical wave changes as a result. The speed of an electromagnetic wave depends on the electrical properties of the medium. When the electrical properties of the medium change, the speed of the electromagnetic wave changes as a result.
The speed increases.

A solid mass won't travel at the speed of light.A solid mass of any speed can block rays of light from the Sun, if it happens to pass in front of the Sun.A solid mass won't travel at the speed of light.A solid mass of any speed can block rays of light from the Sun, if it happens to pass in front of the Sun.A solid mass won't travel at the speed of light.A solid mass of any speed can block rays of light from the Sun, if it happens to pass in front of the Sun.A solid mass won't travel at the speed of light.A solid mass of any speed can block rays of light from the Sun, if it happens to pass in front of the Sun.
It moves at a slower speed!
speed
It stays the same.
they speed up
It decreases.
it slows down
The average speed of the particles decreases.
When any object with mass moves, no matter at what speed, its mass increases. The faster it moves, the faster its mass increases. And the closer to the speed of light it moves, the closer to infinity its mass grows.
They speed up and moves faster and faster.
