1. If the speed of light is a universal constant, then Black Holes must have a weight limit.
Where do you get this from?
As to light speeding up in a material, theory states lights speed can NEVER be exceeded. Ever. Anywhere.
No, it dosn't. It states the maximum speed of light in a vaccum can never be exceeded.
Yet if it is possible within a meterial, it is likely to be possible elsewhere, is it not?
Though it is a simple matter of stating that of course elsewhere light will not be sped up; it's not going to enter the proper materials under the right circumstances. It's like a ball on a flat ledge over a hill; the potential for speed is there but it won't move until a force is enacted upon it.
Force cannot act upon light as it has no mass. Increasing a lights energy changes it's frequency, not it's speed.
2. Then explain a lovely little Quasar called 3C 273. Observed at a distance of about 660 Mpc's, the two "blobs" that compose it moved apart about 0.002" in 3 years. Calculating this distance shows that they moved about 10 times the speed of light over that time.
Can you cite a source for this?
3. Not entirely. It just means that FTL is possible simply by not moving faster than light, so even FTL-as-the-limit theorists can agree on such things.
If your not moving faster then light then it is not FTL.
4. Not so much lack of evidence. There is evidence but it's majorly ignored by the scientific community and remains uninvestigated. As to the conspiracy theory, Conspiracies are usually pointed out by an intent to cover up evidence more than evidence itself. I agree, there is little proof to its existance, (Except the existance of government documents that support their existance, repeated denials of the Freedom of Information Act concerning the existance of Aliens, government officials and military officers who request, but are denied, freedom from their Confidentiality agreements to talk on the subject, etc.) but still....
Well then, can you point me to some of this evidence? If there is as much of it as you say, surly you can provide a link to some.
