At what point does a best guess become fact? When the error is 1%? 0.1% 0.0000000000000000001%? Certain things are known, Wien's Law is a fundamental conversion between wavelength and temperature.
I see what you are saying, but at some point a best 'guess' is correct. My best guess for a stone being thrown out of a window is that it will go down so how many times does the experiment have to be performed for the best guess to become a rule? I don't see anyone disputing this case of (simple) gravity.
When people say theories change all the time, it is not really 'change' but more refinement. Take the recent faster-than-light neutrinos proposal (generally thought not correct), even if it was proven to be true and Einstein's theory was 'wrong', einstein's gravity would still get 99.99999% of situations correct, and a refinement would have to be made to take care of neutrinos or what-have-you.
What I'm saying is, even if the law that is Wien's Law happened to be wrong, it would still be correct in 99.99999999999999999999% of situations, just maby our understanding of the star's temperature would go from 10000k with an error of 100K to 10000k with an error of 200K.
Quantum physics and relativity being the two 'revolutionary' ideas of physics which changed everything 'dramatically', still doesn't matter to many physists who continue to use classical techniques to understand physical processes. Changes to theory =/= all previous physics carried out by the theory is incorrect.Last edited by Ricky116; 12-05-2011 at 09:54 PM.

I'm not to sure if any of you realise this, but 600 light years in the grand scheme of the universe is rather short... in fact it is extremely short, the furthest galaxy humans have discovered is 13.2 BILLION light years away : http://www.abc.net.au/news/2010-10-2...xy-yet/2306322
with the way technology is going, i wouldn't be surprised if we find a way to go faster than the speed of light ( which scientists have recently discovered is infact possible) or infact chryogenically freeze humans to travl to that planet, set up a teleportation device and have instant access to that planet.( kind of like the plot of 'lost in space')

I suspect it would be more likely we'd go to the Gliese system before this place as it's only 20 light years away. Temperature isn't really that high on the list of the priorities--it tends to get colder in space than on ANY planet and we can deal with space--and 22b still hasn't been confirmed to have a solid surface; it could just be a small gas planet with crushing air pressure, the wrong kind of atmosphere and weather that would destroy anything you expose to it.
