Whih university did you do your PhD and postdocs at? Also, lease list some of all of these PhD holders that said this. I have two friends who hold PhD's in organic chemistry that I regularly have coffee with at my University (University of Saskatchewan) and I'd like to see if they've heard of any of these guys' work (or I can just do a literature search from my office computer at the university).
Your post sounds like a lot of trolling.
I'd agree with this. F = ma is a suitable first order approximation for objects moving at velocities less than about 10% of the speed of light. Newton's laws were shown to be an approximate form of a more complex dependence.
This comment couldn't have been written in the seventies for several reasons. First of all, the ability to construct a superconducting field coil of the size required for ITER has only been realized in the past few years. If you look in literature, all literature referring to a possible commercial reactor have pointed towards an ITER type machine for at least the past 20 years. It was often referred to as an Engineering Test Reactor (ETR). ITER still requires a suitable energy extraction/tritium breeding system but so far as having a fusion power output greater than the auxiliary heating power, I can't see how ITER won't achieve this. Current design for operation in what is referred to as ELMy H-mode (a mode of improved confinement) has ITER producing 500 MW of fusion power with 50 MW of auxiliary heating power.
Well, I work on a tokamak and I read the major Plasma/Fusion journals on a daily basis (Physics of Plasmas, Plasma Physics and Controlled Fusion, Nuclear Fusion, Physical Review Letters, etc.). I've never come across a single peer reviewed journal article on this machine or by this author. Also, the article makes no reference to any published work. I'm going to have to doubt it until I see some published results.
Good post. I recall a lecture I had from a PhD from Los Alamos when I was doing my undergraduate degree about the group velocity exceeding c, but they could still not transmit information at that velocity. The information velocity isn't the phase velocity, but it isn't necessarily the group velocity either.
I believe I answered that. It is the CP violation. That is why we live in a matter dominated universe. This would have occured in the very early universe when the energy density was still high enough that there were enough 931.5 MeV photons around to produce proton-antiproton pairs. If you have an extensive background in Physics I can describe how it's arrived at in the theory, however it still probably won't be too helpful as the result falls out from a lot of fairly complicated math (Graduate to Post Graduate level).

There is an "overabundance" due to what is called Charge-parity violation. It is an very small (1 part in a billion) asymmetry in the production of particle-antiparticle pairs. For every 1 billion particle-antiparticle pairs produced, there is one excess particle produced. This results in the matter dominated universe we see. This has been shown experimentally as well as theoretically.
Well, at this point it is unreasonable for them to get their hands on it. It is very hard to contain and it doesn't exist in sufficient quantities. I suppose in the future they could get some, after the proliferation of antimatter producing devices as well as suitable storage methods for large amounts of it (large relatively speaking, maybe a gram or so).
As pointed out, antimatter is very real. It is created all the time. Anti-electrons (positrons) are created in nuclear decay happening all the time. They exist in nuclear reactors. Anti-protons are created in particle accelerators such as CERN and the one at Fermilab.
As for space, there is something in the standard model of particle physics called Charge-Parity (CP) violation, which is an asymmetry in the creation of matter. Basically, in the early universe for every 1 billion proton-antiproton pairs created, there is one excess proton created. After all the other pairs annihilate, we're left with the observable normal matter universe that we see today. This CP violation has also been experimentally concerned. In fact, all particles have an antiparticle. Some are in fact their own antiparticle, such as a photon and the Zo boson, in that their properties are such that there is no opposite.
And in fact, a matter-antimatter annihilation would convert all of their mass into energy. This is commonly seen in particle accelerators, as the energy release is a pair of gamma ray photons of very specific enerygies.
How do I know? Well, I'm a physicist.

I imagine that you've stumbled upon the flaw overlooked by teams of experts on General Relativity.
