I think if you fully understood the implications of my dream comment this one still does not apply.

PossA: We could all be the extended consciousness' of a hypothetical organism
PosssB: Dreaming only proves that you can think, you cannot multiply thought or the ability to think. Thought/think+thought/think does not equaly 2thought/think.

It can be demonstrated that all empirical 'knowledge' (science) can be seen as a product of chance, not in fact true knowledge:
(heres a little scenario).
Laguna drives his car on a country road, near to a village that has recently had a competition to build the most convincing barn facade (ie boards that from the road look exactly like real barns).
As he drives, he comes across them. There are 4 barn facades on his left, and 3 barn facades on the right with a real one too. Iti s impossible for Laguna (even though he has excellent eyesight) to tell the difference between the fake and real.
However, by chance, Laguna points at the real barn and says "ooh, i can see a barn." Yet he was just as likely to do that do a barn facade, and say the same thing.
This is not knowledge, whilst it is justified - Laguna has good eyesight normally and can see the 'barns.' He believes it is a barn (for something to be knowledge you must believe in it to be possible and true) and thirdly it is in fact true that there is a barn there which he has pointed to. However, as he was just as likely to say the same about the fake barns, and came to the truth through observative chance, it is not knowledge.
You can appply this to physics- they may have observed themselves creating an 'anti hydrogen particle' in a lab - as the result may have been them observing it balance a hydrogen particle. However, there could be an unlimited number of unobservable forces and mechanisms at work, and we are only observing that result throguh chance, and see the cause and effect to be that way when it fact it is only circumstantial.
To give a more easy to understand example of this, you can look at the problems of global warming and global dimming.
Whilst global warming is well known (and disputed, but that is not relavant to this argument) as a product of excess gases in the atmosphere trapping heat and causing a general rise in temperature, attempts have been made to clean up our factories and lives to emit less gases and less pollutive particles. A good idea you would think.
However, scientists recently realised that the amount of light reachign the Earth's surface has reduced, due to the amount of pollutive particles in teh air, thus slowing the process of global warming down (for evidence of this just google it). in attempting to reduce pollution output to improve health and the global warmign situation, in fact we are reducing this effect and making the Earth heat up faster (the less pollutants in the air, the less light from the sun is reflected and the Earth heats up.)
Before this phenomenon was discovered by a couple of scientists in Australia and Germany, it was 'knowledge' that reducing emissions and pollutants would slow global warming, where in fact there was an entirely unobserved factor working in the background.
