Some days ago I saw some people here saying that billions of dollars was wasted in LHC. I would like to know their opinion about new findings. The post in question http://news.ycombinator.com/item?id=2943950 .

This wasn't the LHC. It was a non-LHC experiment at CERN. (I agree with your sentiment, however.)

Agreeing still with the sentiment. However, if this is correct, the data from the LHC will confine the new theories, which will be very important.

am i the only one that has come to love the scientific method simply because it creates more questions than it answers. there is just so much that we do not and cannot understand. the more we learn, the less we know. fantastic. on the flipside, i would be certain that certainty is a particular kind of hell, if having such knowledge didn't condemn me to it. excuse me while i proceed to consume my tail http://en.wikipe…

The Scientific Method could be boiled down to: 10: Question Reality 20: Verify Results 30: GOTO 10

let's try without GOTO:

    while anyone_cares:
        improve_model()
    
        if theory_of_everything_appears or strong_ai_appears:
            raise Exception("rethink loop")

That can't be it because the error wouldn't straddle the speed of light. It would put the range at 1.000022 c to 1.000080 c, both of which exceed c, so they wouldn't have written it off as error.

But that doesn't indicate a hard error bound; this is a statistical matter, after all. Most likely it's just an expected standard deviation.

It indeed is the standard deviation.

There was an experiment where an impulse of light came out the other end of a material faster than light could have traveled through vacuum in the same space. The eventual explanation was as follows - imagine that your outgoing bunch of photons looks like this: :::... The first three photons are "invisible" because there is so few of them that they are below the equipment sensitivity. The second group of six particle…

The fun thing is some physicists manipulated group velocities to create time lenses

If this result is valid then it would mean that neutrinos are capable of traveling .0025% faster than light. There was a supernova that we observed in 1987 (SN 1987) that occurred 168,000 light years away from us. A neutrino burst was observed in 3 different labs about 3 hours before the light was observed. If neutrinos are capable of traveling .0025% faster than the speed of light then why would we observe these neu…

The faster-than-light neutrinos got slowed down on their way to us by other faster-than-light neutrinos they encountered on the way?

The models are secret... wait, seriously??

Short answer is no, long answer is sort of. The way in which data / code is released is a complex issue. However, if your willing to wait a reasonable amount of time AND pay for the costs involved you can get just about everything produced. Still, in the larger context validating someone's data is basically worthless activity. It's far more important to go out and collect new data, build a new model, run a new simula…

Well the model is the thing that tells us what effect a rise in temperature/CO2 would actually have, no? Seems common sense to me that this should be open so that people can judge it. You could program a model to say anything regardless of the data.
