Likewise, Vish. Well, to answer your question, or try to,...the wavelength is the 'natural' unit, as is the period, ...different wavelengths have different periods, but wavelength/period is always a constant. There is a wavelength of 299 792 458 m that has a period of 1 s and frequency of...

Just because I choose to argue with you doesn't mean you're wrong. And you're not the only one to have said that, just the most recent. I suppose another way to put it is that wavelength divided by period (I think that's the correct term) is also a constant (the speed of light) I was...

A lot of articles on this subject, including the article I linked to at the beginning of this thread, refer to the 'fact' that anti-matter travels backwards in time. Would this imply that at the moment of the big bang, matter not in contact with anti-matter started traveling forwards in time...

Anti-hydrogen atoms have been trapped/stored for the first time at CERN. http://newscenter.lbl.gov/news-releases/2010/11/17/antimatter-atoms/

JD, I agree, The radiuses I was quoting were the 'accepted' ones. There is a problem with my maths as well, the 50,000 I quoted is radius, not volume. I think I need to multiply by 4/3 pi r^3, or something. While the two electrons you mention do occupy the same space, they do not occupy...

You are actually 'seeing' photons, not the actual event. Photons are radiated or reflected from an object and take time to travel to the eye of the observer, where they are converted into electrical impulses and passed to the brain. You don't actually 'observe' the event, just the photons...

Zapper, I was actually dividing E by c^2 (within the context of E=Mc^2, which we all know is flawed) In this case, E is a very small number and c^2 is a very large number, so the answer is ~0. On the subject of dividing 0 by 0, however, zero divided by anything is zero, and anything...

Zapper, Einstein said his theories were only approximations. I seem to remember this is why he gave us general relativity and special relativity. a very small number (~0),divided by a very large number (~infinity) equals approximately zero. I think you'll find that a lot of Einstein's...

No, Zapper, you've misunderstood. I've just re-pr=hrased the question, not provided an answer. There are other ways to re-phrase the question as well, as you have pointed out. (by the way, photons are energy, they have no mass, but they do travel at the speed of light.If you want me to...

Zapper, I chose a reasonably simple equation without any dimensionless constants for a very good reason. I'm aware that there are other equations with c in them, but E=Mc^2 was the simplest one I could think of. I assumed it would be easier for most readers of this thread to relate to, rather...

Dave, once again I'm forced to concede that you are correct.

Dave, by saying 'might' you are, by default, arguing that 'it is POSSIBLE that a time machine WILL be invented', yet you don't give any example of accepted scientific theory to back this claim up. All the evidence we have indicates that the OP was correct in stating 'a time machine will never...

Dave, if we look in the bag and can't see any marbles we can conclude that there are no marbles in the bag. Similarly, if we look for evidence that people have traveled back from the future, but can't find any, we can conclude that a time machine will never be invented.

Jared, if I argue that there is no evidence that a time machine will be invented in the future because no-one has traveled back from the future and that if a time machine were to be invented in the future then there would be evidence of it because people would have traveled back from the future...
