no one has answerew this yet... Well I will then. 1. Go to wikipedia 2. Go to the library. (if you are going to discuss something with a college professor get a book. Trust me there are tons of them.) 3. Listen to me (but dont expect everything I say to be right) 4. Ask a teacher. Dark matter is supposed to be the force that holds galaxies together. It is an invisible matrix that provides the excess mass needed to account for all the galaxies today. Supposedly the universe does not have enough mass to produce all the galaxies it has also galaxies have a stronger gravitation than there suppose to. This is where dark matter gets involved. Currently we are searching for a candidate for dark matter, but the evidence is all there. The best candidate is something called an axion. This is a mysterious particle that fixes many problems in quantumchromodynamics. (I dont know what that is so dont ask me) Goodluck, and get a book!

I thought they were interesting...

Thankyou Fredrik, I like the way you think & appreciate the help. Now I would like to post a hypothesis I have do you know a place where I can do this? Well better not be lazy... I suppose I could look.

Nice answer ms. penguin Now lets ask ourselves did that really help any. Did you learn what you have just to keep it to yourself. I doubt your as smart as you think. I still dont know QFT means. You see that is what we call jargen and not only jargen but abbreviated jargen. And the truth is that I might actually understand what your talking about if you would stop being a smart. And spen the extra FIVE seconds of your God given times to spell out the words QFT for me. Please prove your intelligence to the world....

What do you mean.... I have thoroughly explained that tachyons have imaginary rest mass and hence negative mass in reality in this thread. http://uplink.space.com/showflat.php?Cat=&Board=phenomena&Number=658235&page=0&view=collapsed&sb=5&o=31&fpart=11 And for Cherenvok radiation..... Yes you did say that, but you never said they were charged why

Thankyou by the way I went t the library and did some research of my own. It urns out tachyons have imaginary rest mass because mass squared is less than zero this means tachyons have negative mass? I think. Also the effect you describe can happen only when tachyons are charged.

True, Many theorists believe the universe is expanding FTL. Does this not mean it is in the nature of the fabric of space-time to react Superluminaly to things?

Tachyons have imaginary rests mass and they do have real mass now does anyone know if they have positive or negative mass? Definitely. Thanks why06

Here you do not fully understand the question. Tachyons have imaginary rest mass. There for they would seem to have real mass to a STL observer. Now I am wondering weather that mass would be positive or negative. Currently we are leading to the side that tachyons may have negative mass, but we have not got a flat out answer yet. If we can not reciev one. I will infer the answer to the best of my abilities. Keep posted about the conversation on other sites. If someone trained in physics could give us a definitive answer that would be great. Thankyou why06 out

Hello Im new here, I suppose he is talking about an antiproton powered spacecract since all the others would not make sense, but who knows maybe he wants his craft to instantly annihilate

Hello Scienceforums.net, I am why06 from SDC (space.com) This may sound a little weird but I am seeking help from many different scientific communities to answer a question that is baffling us at SDC. About three weeks ago I started a thread in SDC in the Space Science & Astronomy section. It was about a possible substitute for dark energy and matter dealing with tachyons. I am not here to discuss this though. No this hypothesis can be saved for another time. My question is one dealing with the physics of tachyons themselves. All of the minds put together at SDC could not figure this question out but perhaps YOU can.... Question: The question is not as easy as it seems. But we would really appreciate it if someone of enough knowledge pertaining to this ssubject can answer this question. A warning to those who try to solve the problem with a quick link...... WE at SDC have been discussing this isue for 11 PAGES of 20 post pages. There are approx. 200 Posts on this subject!! We have simply found that their are to many discrepencies in internet sources to find a true answer. The original thread at SDC: Dark Energy and Tachyons The same question asked at BAUT: Imaginary Mass = Negative mass? Thankyou and Goodluck with this baffling question. If you would like me to post my hypothesis or need to ask me a question on the subject Post it or PM me at any of the three sites. why06 out:cool:
