blike Posted May 8, 2003 Posted May 8, 2003 BTW I picked up this book a few days ago. I'll let you know how it is
JoeDaWolf Posted May 8, 2003 Posted May 8, 2003 Originally posted by fafalone Where's the evidence for it? I've seen evidence that the speed of light has not been constant over large timescales. It's also a well known fact that light travels slower through mediums (like air or water), but I haven't read this book... so perhaps you can summarize what evidence the author presented. The distance that light travels / time it takes the travel the ditsance < c, but it doesnt mean that the photons are travelling less than the speed of light. The photons have to enter the medium, get absorbed and emmited by all of the particles that stand it the path of the photon, correct? I know that it takes photons around 30,000 years to escape the center of the sun, going through a "random walk." ~Wolf
cHIs- Posted May 14, 2003 Posted May 14, 2003 If we did figure out traveling faster than light speed, would it make Einstein wrong? i dont know alot about science so im asking, did Einstein say for a fact that it is impossible to travel faster than light? if he didnt say it as a fact then we cant say he was wrong.
Guest SirTony76 Posted September 5, 2004 Posted September 5, 2004 Unlike most who posted here, I actually read the book. I would actually like to see his essay on it though, the book did not go into enough detail. Does anybody know where these physics archives are on the web that he described in the book? He brought up many interesting perspectives, I've talked with a few guys over at Fermilab, and most of them are at each others necks about this theory. Anybody who says this guy is wrong without a doubt is unscientific. To actually do science, you need to challenge ideas, think of new stuff, and be very creative. Joao thought outside of the box on this one. There are a lot of things in Physics that do not work out right. With the way he described his theory everything works out, except that whole constant speed of light thing. This book is worth the read. Tony

Well I think at this point he couldn't have been completely wrong. His theories have been endlessly tested, but have really held up, with important practical implications. Einstien will probably be "wrong" in the same way Newton was wrong. His theories were very accurate in every way measurable at the time, but there are exceptions where the theories were not accurate, which is why relativity was developed. Relativity will probably turn out to be not totally correct at some point in the future, but that doesn't make Einstien or Newton "wrong".
budullewraagh Posted September 5, 2004 Posted September 5, 2004 well, somebody slowed light down to 25km/h and i can almost run that fast :\
Flak Posted September 6, 2004 Posted September 6, 2004 Interesting post. I dont think Einstein is wrong, but I think that speed can go faster than lightspeed, and that photons may have some kind of mass.
ydoaPs Posted September 6, 2004 Posted September 6, 2004 you haven't presented ANY evidence to support you. until you do (or even put forth a logical explanation), shut up about it.
Thales Posted September 6, 2004 Posted September 6, 2004 He is entitled to his opinion, no matter how wrong and baseless it may be. That said arguing for the sake of arguing shouldn't be condoned either. Photons have no mass and nothing (with mass) can travel faster than the speed of light. If you don't understand why find any site on the web that explains the basis of special relativity. Either that or, as above, please provide evidence, if not, at least some basis for such claims.
swansont Posted September 6, 2004 Posted September 6, 2004 He is entitled to his opinion' date=' no matter how wrong and baseless it may be.[/quote'] Yes he is, but he's not entitled to his own facts. In the end, in science, opinion means squat.
Thales Posted September 6, 2004 Posted September 6, 2004 True but pointing that out is more productive than telling people to shut up.

Because on ecuation this will give you an infinite amount since light speed is the speed limit used. However if speed limit is higher wont be a problem for a mass object went into the lightspeed and even go over it.

The problem with a solution that has imaginary energy is that it violates conservation of energy (as the real term goes away) and nobody knows what imaginary energy physically represents. c isn't the speed limit used, as such. It's the limit that naturally falls out of the theory.
philbo1965uk Posted October 9, 2004 Posted October 9, 2004 well said sayonara and jakiri.also god does not play dice is the most profound statement a man of Einsteins massive contribution to physics could say.I wish more people understood its meaning,sadly they only see the words and drift off into the quantom cesspool
[Tycho?] Posted October 9, 2004 Posted October 9, 2004 It isn't a massive contribution. It isn't a contribution at all, it was his opinion at the time. His massive contribution was relativity and other work. This dice comment was not backed up by any physics, in fact it was contradicted by physics. Its meaning is pretty clear, since Einstiens opinions on quantum mechanics were well known.
Sayonara Posted October 9, 2004 Posted October 9, 2004 Of course, there is the view that he was considering the viability of god and not dice.
[Tycho?] Posted October 10, 2004 Posted October 10, 2004 I've never heard that before. If he was talking about the validity of god, then he was being rather abstract about it.

Tony[/quote'] http://arxiv.org/abs/astro-ph/0305457 I've met him - he's a bit of a loudmouth, making claims which he doesn't really live up to. The idea is OK, but a little bit unbelievable, and frankly rather uninteresting except for the fringes of the observable universe. The papers make a lot less outrageous claims than the book, which is frankly just an exercise in sensationalism (sad that it works...).
Kedas Posted October 11, 2004 Posted October 11, 2004 Of course, there is the view that he was considering the viability of god and not dice. The way I always understood it is that there is an explanation behind things. as far as I know he was convinced everything was based on some 'simple rules'.
