Someone is shooting faster than light particles at you and you accelerate toward the shooter. Do the tachyons speed up, slow down or remain the same speed?

I wonder, if i stand in the centre of a small meteor crater with a powerful d..k on a spinning turntable can I easily get my pee spot on the crater wall to travel supersonically?Originally posted by Marts Liena
If i stand in the centre of a wide meteor crater with a powerful laser on a spinning turntable I can easily get my laser spot on the crater wall to travel superluminally. Does this mean the spot is a virtual tachyon?

What do you mean most correct? What more are you looking for?
I guess I'm presuming by the statement of the problem that you observe the tachyons as moving from the shooter towards yourself; if you perceive the tachyons going the other way, then as you accelerate towards the shooter you will perceive their speed shoot off towards infinity and then they will slow back down, now going the "right" way.

Janus' answer is the most correct one so far.
jcsd is correct insofar as the speed decreases, but the derivation and values are incorrect. The first one has a clerical error, but that aside the derivation for STL speeds is
V=v1+v2/1+v2×v2
and for FTL speeds is
V=1+v2×v2/v1+v2
but the one for combining both types of speeds involves separating the space and time parts and putting them together another way. Unfortunately I haven't worked out all the details yet, but I do know that in a sense the FTL and STL regimes are inverses of each other.

Erm, where did you get that equation for FTL travel, it's incorrect as it cannot produce values above c, meaning when you add 2 and 0 you get 1/2 which is nonensical (as essientally says that you can change the observed value for the speed of an object without changing reference frames).

Tachyons are hypothetical particles that travel faster than the speed of light. They are important because their existence could potentially challenge our current understanding of physics and the laws of the universe.
The concept of tachyons is currently only theoretical and has not been proven by any scientific experiments. Some theories suggest that tachyons may be able to exceed the speed of light, while others argue that it is impossible due to the laws of physics.
Tachyons, by definition, are thought to travel faster than the speed of light. This means that they would be able to cover a greater distance in a shorter amount of time compared to photons, which are particles of light.
If tachyons do exist and are able to travel faster than the speed of light, it could potentially lead to violations of causality, which is the principle that cause must always precede effect. This could have significant implications on the concept of time and the laws of cause and effect.
Currently, there are no known practical applications of tachyons. However, further research and understanding of these particles could potentially lead to new technologies and advancements in the field of physics.
