I read that tachyons move faster than the speed of light and travel "backwards" in time.

damn, I always thought tachyon fields were used to find cloaked romulons in the neutral zone...lol...
thanks for the link Lulu...

I see my friend Duncan has revealed his skepticism is not real. His twisting of the facts reminds me of government controlled mainstream media propaganda .He obviously is aware, hell he KNOWS whats going on and he is here to lead you from the truth.The data and the progression of events is undeniable, and I fear that the way the lid is being kept on this, I'll never get to tell you all I told you so. The Suns overall energy output is fluxuating wildly ,as is the magnetic field in the solar system. My prediction is that these are the end times as described by Ezekial the prophet and that there will be no year of "our lord" 2002.................. |

Dear Ms. Lulu
Let me quote from the web-page you cited.
If such particles did exist, however, Special Relativity implies that they could never be slowed down to velocities below the speed of light. The existence of such particles, called tachyons, has not been totally ruled out, but several experiments have tried, without luck to detect them. If they did exist, and they interacted with ordinary matter, it would give us the means to communicate with the past. Tachyons could literally be sent outwards, bounce off a tachyonic mirror, and return before they were sent. This in turn would give rise to a great many logical problems. For example, if you sent a message back in time that caused your grandfather to be killed before your father was conceived, then you would not be around to send the message that prevented your birth, so that you would be around to send the message, so that you wouldn't be around....etc.
"If such particles did exist, however, Special Relativity implies ... The existence of such particles, called tachyons, has not been totally ruled out, but several experiments have tried, without luck to detect them...
Translation: Either there isn't any such things as tachyons, or, if there is, no one has ever seen or even detected one yet.
That doesn't mean that "tachyons" are fraudulent physics -- by any means. What the physics theorists are saying is something like: "if there were such a thing as a particle whose space-time travel plans were a mirror image of the rest of the matter in the universe, boy, it sure would validate these hypotheses!"
And that's how theoretical physics works sometimes. If you have a hypothesis that requires a hitherto-unseen structure to make it work, then try to find that structure. Sometimes you will find it and it gives a boost to the hypothesis.
"Tachyons" make a lot of sense; if there were such a thing, our physics would be easier to comprehend. But, we simply don't have any evidence for them -- not yet.
"Tachyons could literally be sent outwards ... bounce off a tachyonic mirror..."
Again, maybe they could, maybe they couldn't. If you're postulating a particle for which you have no evidence, it's kind of silly to talk about a way to "send" them or to "bounce" them off a "mirror" since neither a "sending" methodology or a "tachyonic mirror" even exist -- at least, not yet.

Dear Mr. Seeker:
I have taken three physics courses (assuming you don't count statics and dynamics as physics), and one of those was in high school in 1963. I am certainly not knowledgeable in any of the more esoteric physics studies.
But if you postulate a gamma ray burst from a source outside the solar system, the closest source that I know of, Proxima Centauri, is 4.3 LY, or 2.54539 X 10 ^13 miles, away.
Given that gamma ray bursts, like every other EM-spectrum event I know of, has to follow the inverse-square rule for propagation intensity; I can't imagine any extra-solar system event other than a nearby sun's supernova that would cause a noticeable gamma ray burst in our neighborhood. And Proxima Centauri hasn't gone supernova yet.
Again, it's been many years since I took any physics courses; perhaps if we had a scientist (as opposed to an engineer-turned aerospace bureaucrat) here, we could get better information. But based on what I remember, gamma ray incidents originating outside our Solar System simply don't seem like a likely source of much problem. |

Mr. Kunz, you stated: Translation: Either there isn't any such things as tachyons, or, if there is, no one has ever seen or even detected one yet.
Two pieces of matter in opposite time direction may not be observed by each other. The speed of light = zero time. At the zero point, the object appears to actually become light, and beyond that there is no observation. Therefore another way of detection besides visual observation must be used to to prove the existence of "tachyons".
don't have any evidence for them -- not yet...exactly, not yet...but it is only a matter of time.

The speed of light = zero time.
I'm not understanding this, Lulu. Could you please explain it further for me? |

quote:
Anything travelling at the speed of light is frozen in time. The general reaction to this statement is "Huh?" but with a bit of explanation it can be made clear. It all goes back to Einstein's theory of relativity: time is relative to the observer. Once again skimming over the details (which, it seems, only Einstein would understand), we discover that as an object accelerates, time slows down relative to that object. It seems that time and speed come together at - you guessed it - the speed of light. This is to say that a person riding a beam of light would be frozen in time - relative to everyone else, he could travel for several million years without aging a single second. To himself (since, relative to himself, he will always be stationary) time appears normal - it's just that the rest of the universe seems to be aging infinitely quickly!

The excessive momentum carried by an Faster than light particle constitues a unique tachyon signature. The production of a tachyon in a bubble- or spark-chamber can be inferred if energy-momentum accounting leads to a big deficit in the energy column. In at least 12 or so accelerators around the world, thousands of pictures of high energy collisions are taken every day, each one a potential portrait of a tachyon! Blessings, Joanne ^j^ |

Duncan,
Thanks for the reply, and you can dispense with the formal references, me anyway, seeker will do just fine, just don't call me shirley 
But if you postulate a gamma ray burst from a source outside the solar system, the closest source that I know of, Proxima Centauri, is 4.3 LY, or 2.54539 X 10 ^13 miles, away.
actually that was not my inference but the authors....I'm just wondering what known event would cause the drop in the solar wind...
black hole passing near our system maybe ?
might be a good time to mail Holger Pedersen

I want you all to think of our current understanding of physics as it relates to our knowledge of physics 100 years ago.The point is, we now have a totally different perspective on it, and in another 100 years many of the "facts" we now "know" will seem ludicrist.Trust me, we are not even close to understanding the universe and how it was formed. |

Schoolmarm here. You can see that this is real science because of all the hedging:
1. They changed the title to something less provocative.
2. They use "may"--"the speed of light - may have been ever so slightly smaller"
3. They use "if"--"'It's just a very nice piece of information, if it stands up.'"
4. They use "cautious"--"'I'm quite cautious about whether to believe this result,' Bahcall said."
5. They ask for more grant money--"The scientists hope to confirm their results using a different telescope, perhaps the Very Large Telescope at the European Southern Observatory in Chile." |

According to Einstiens theory of relativity, even if two obserbvers are moving away or toward each other at very high velocity the speed of light originating from one source and being recieved by the other is always 1.86 x (10)5 miles per second. This part of the theory has been proven to be true |
