Apparently, radio emissions from a pulsar are going faster than light due to anomalous dispersion. Thoughts?

Well, according to Einstein, anything traveling faster than light goes back in time... so he was obviously wrong . However, it is not inconceivable for this to happen - it is entirely possible for anything to go faster than light. The reason scientists have believed nothing can go faster than light is because in their particle accelerators where they attempted it, when a particle approached light speed, they couldn't make it go faster. They accelerate using magnets. Consider this: if magnetic "fields" were actually a type of particle that did not go faster than light, then the field could not force a particle to go faster than light because the particles of the field itself don't. The effect would be as observed: the particle approaching light speed, slightly slowing down, slightly speeding up and so on. Therefore, the only way is probably with a combustion engine, but the required amount of fuel would be phenomenal. Therefore, it must still remain a dream to us

No, its not possible to go to faster than light speeds with a combustion engine, because as your speed approaches the speed of light, your mass starts increasing rather than your energy.

Whos to say those waves being detected aren't from the future? What would the difference be from our end from detecting a radiowave from the present and detecting one from the future?

This is exactly what I though!

The only reason something can't go faster than light is because propelling something faster than light requires energy that is faster than light. Think of these propulsion methods:

Magnets - The magnetic waves don't go faster than light, so magnetic propulsion won't go the speed of light.
Ions - Ions can't go faster than light because they are being accelerated by electricity (which doesn't go faster than light), so when an ion pushes something, it can't go faster than light.
Chemicals - Chemical explosions use heat to expand some sort of gas and push something forward. Since heat is a byproduct of light, the air can't expand faster than light. Therefore, it can't go faster than light.

Now I was just thinking off the top of my head on those. I may not know how they work exactly (too lazy to look it up), but I think you get the idea.

If radio waves are infinetely compressed, do they not form matter?

radio waves are a wavelength of light, ergo they have no mass. THe problem is, how do you get light to go noticeably faster than c without using a Cassimi vacuum?

Well, electromagnetic waves DO have mass... So I guess so... technically

Mass increases when you approach the speed of light, that is known, but when you reach the speed of light, based off of the math, you're mass reaches infinity and the energy needed to keep that going needs to be infinite also, and sense we have never found an infinite energy source, I don't think we will have spacecraft going past the speed of light.

EDIT: Oh, and sense with infinite mass you will be like a super ultra black hole and watch the surrounding galaxies fly towards you, but because of time dilation, it will be like slow motion lol

But they are effected by gravity, right?

Isn't everything effected by gravity have mass?

I had this discussion with Thomas (I think) before. Gravity is not affected by mass, objects with gravity bend spacetime, and objects follow these bends. So even massless particles will follow these curves.

The question is radiowaves are just a form of energy and
E= mc^2. How then does antimatter form in a collider? The anti particles that form antimatter were not present previous to the collision between the two protons which is an extreme force of energy being compacted. As a result the protons lose momentum due to a loss of velocity because they just collided with each other.

If you had an infinite force compacting radio waves would they too compact into matter, however that process wouldn't work if objects that travel at the speed of light reach infinite mass. How then does this form of energy go FTL if that were the case?
The answer might be that since photons have no mass, then (infinity)(no mass) = no mass. This would imply however that mass reaching infinity is NOT dur to an outside force but a component of the mass itself.

well we really dont know much about the subject seeing as we cant go that fast so i say it is a possibility but not a likely one

I think Relativity is an incomplete theory. We still have far more to understand. However, I think matter is just lots of energy, so now, thinking about what you said again, I suppose that is what would happen. From what I know (or think I know :lol it would seem that is what would happen anyway.
