Some of the readers of this newsgroup might be interested in a FAQ
just posted to the rec.arts.startrek.tech newsgroup. The FAQ is
called "Relativity and FTL Travel".

Basically, it is a straight forward look (written for a non-technical
person to follow) at Special Relativity, General Relativity, and the
problems and "solutions" one finds when considering faster than light
travel.

For more information, read the "Introduction to the FAQ" portion which
you should find in the r.a.s.tech newsgroup. You can also take a look
at the other versions of the FAQ (e.g. HTML and LaTeX) from this URL:

http://www.physicsguy.com/ftl/

Followups to this note will be sent to the sci.physics.relativity
newsgroup, and for more information about Relativity, you can also
check out the Usenet Relativity FAQ:

Enjoy, and feel free let me know what you think.

Errrrrrrrrrrr - Jay what gives? You have been posting the same message
claming this FAQ has been recent posted since at least 2003
http://groups-beta.google.com/group/...5?dmode=source

Or am I missing something?

Thanks

It has been recently posted every single time. It's normal to regularly post
FAQs to relevant newsgroups, whether or not they've changed. In the case of
s.p.r he's opted for something in between: posting a pointer rather than the
full text. Nothing wrong with that. I just wish the FAQ itself were more
accurate.

I have read this and I would like to link up tachyons with some of the
basic principles of Particle Physics. I don't think this FAQ has done
this completely. If we take for example a Proton. It consists of 3
quarks and a mass of interactions. The three quarks by the way are all
of them more massive than the Proton! Interactions between elementary
particles are governed by the Feynmann diagram which is basically a
list of all the interactions that can occur.

Tachyons, if they exist, are governed by Feynmann diagrams. A Feynmann
diagram guarantees the CONSISTENCY PRINCIPLE. Feynmann diagram will
never allow you to kill your grandmother. Because of FDs tachyons can
never exist in any sort of free state any more than quarks can. Each
quark as I have said is more massive than a Proton and so a free quark
will immediately create other particles.

A Tachyon will have an infinite world line and will create a timeline.
As with most of physics the tachyon will go into its lowest energy
state. This means, in effect, that a timeline is established in which
communication between past and future is difficult.

What does this mean. Is Randi's $million safe? Yes it is. If there are
no tachyons then no one can detect the future. If there are it will be
detected very sporadically when chaos threatens to move us from an
established timeline. Remember tachyons will be in some kind of
thermodynamic equilibrium. People will have insights from time to time
but no one can have $1e6 consistency. It rather looks as if the Police
should look to their own officers and not employ psychics.

Thanks for clarifying it. I found it a bit confusing.

It is interesting to note that SR does allow the existence of tacyons, some
theories like M theory predict them, and they may even be detectable.
However if you could use them to send information FTL then you have violated
cause and effect (if SR is correct) A rather interesting existence indeed.

Thanks

But as I said Feynmann diagrams inpose consistency. A tachyon will
quickly go to infinity, so like the quark cannot exist free. There will
however be some residual effects but NOT free tachyons.
