Now you've lost me a bit. Is a tachyon the same as a neutrino?

You have been speculating the recent news that a nuetrino could violate causality. That would mean the neutron would be a tachyon.

I apologize, would mean the neutrino would be a tachyon! See am getting mixed up now!

If a tachyon is sent to a receiver 1Ly away it might only take 6 months to get there but it will still arrive 6 months after it was sent... cause still precedes effect.

The only problem arrises in the frame of the tachyon itself. It's only in its frame that effect precedes cause, that it arrives before it is sent.

You will have to expand on this a bit.

But why exactly going faster than light upsets cause and effect? Nobody has spelt it out yet.

I have said it in plain English.

Well assuming they move faster than light, and that relativity holds.
Sending something faster than light in one frame is the same as sending a message back in time in another.
Once you can send a message back in time you run into all sorts of things like the grandfather paradox.

If this isn't enough I can try and explain exactly how it entails sending a message back in time,

Wait, if the speed of c is the speed of c to any frame of reference, how could we know that's true? Is there some graph that's like a quadratic that shows some kind of reverse of time dilation after x km/s^2 or something?

Curious, I don't think I said anything about imaginary time dilation. I said it was able to oscillate in the time dimension.

That is to say, it freely able to move into the past and the future, obviously many causality problems arise.

Imaginary time is real space. Real time is imaginary space. Travelling at different speeds lets to travel through these descriptions of time.
