If you take a good look at the web-site I provided you will see that what they are saying is not based on speculation but good science. Speculation to a degree is part and parcel of all good science. However, when you start pointing a finger at an idea like this and call it crazy you are stepping out on a fragile limb philosophically. After all the big bang is pretty crazy if you really think about what they are saying about it.
You were talking about the speed of light changing so much so that the stars wouldn't have to be billions of years old. This is craziness, unless you made up a theory that was so different from our current theories but still had as much evidence in favor. I don't think you will do this.
Speculation has little point to good science, which you have evidence in favor of other theories. If you are lacking evidence, then speculation allows you to create theories, which then need to be testable. Speculation doesn't enable you to ignore data though.
We have crazies come and talk at our physics conferences all the time. The fact that very occasionally one isn't crazy, doesn't change the fact that most of them are and that we are right in calling them crazies.
Cosmology and string theory are at the edge (I feel string theory is beyond) science. They aren't good examples of what physics is. There is a lot more speculation in these fields then most of the rest of the fields in physics.
The laws of physics are not necessarily everywhere constant either.
That is actually one of the current key assumptions of physics. It was the key to relativitiy, and a lot of other physics. While some still want to let go of this assumption, the broad majority of the community hasn't yet seen to do so.
Yes, as far as most physicists are concerned, the laws of physics are the same everywhere.
In sub-atomic particles we see some divergence and also within the theorectical confines of a black hole the laws of physics breaks down.
Not among sub-atomic particles, I don't know what you are refering to here (I think you might be refering to quantum mechanics, but you would be wrong).
It is true that in a blackhole (a theoretical object, which we have seen observational evidence for, but for which we have none to do experiments on), our current theories of physics break down. This doesn't mean that physcis breaks down, rather that our current theories are incomplete. (for the longest time there was a bet about whether blackholes exist at all, now most agree that they do exist, but the distant nature of them makes experimentation with them impossible)
So to say this is crazy is not taking a serious look at the things we can observe in science and also what the implications may be. BTW, if you look at the first few theorectical nano seconds of the big bang you will find what they are saying happened is well outside the laws of physcis as well.
Yeah, cosmology and string theory go way outside of the range of physics that we can do experimentation on. Therefore, there is a lot more speculation in those fields, and I expect that it is much more likely that the physics is different then what is in their theories.
BTW, how is friction effected by the speed of light?
Friction depends on the electromagnetic interaction between material. The permitivity of free space is a constant of this interaction, and is inversely proportional to the square of the speed of light. If the speed of light wasn't constant, it wouldn't be constant, and if there was any great change, most everything would be screwy. Including friction.
