A Camera For Looking Into The Future?

If faster than light information means time travel is possible, then there is something wrong with the physics.
It's ARGUED that relativity means that time travel could happen if c can be exceeded. In that case, there is something wrong with relativity theory, or the current interpretation of it.

Causality is sacred because it happened like that?

Nothing's impossible, but you've got to acknowledge the odds and discard what is squillions to one against.

... such as focussing neutrinos onto a detector that could capture enough of them to produce a meaningful image - perhaps if we could solve that problem, it might become more obvious exactly how fast these particles travel and how disdainfully they treat time. My breath; it is not held.

If neutrinos do this they are a indicator that something is very wrong with our perception and understanding of time and causality. It throws enough cards up in the air for anything to be considered at almost any odds against. Shouldn't put odds on this but it is very likely the far past is constantly in change just like the far future and the immediate past and the immediate future are accurately mappable. The idea of technology concerning 'guestimates' of future events like a forward looking camera is that it keeps the public imagination pointing in the right direction. Real 'time travel' might be a 1000years away, like fusion power it is better to say fifty...and keep the funds flowing.

So, Crumple, are you seriously suggesting that there could be a possible future where we're not all doomed?

Yes, there might be a narrow window. If the catastrophe we are approaching is survivable then a few could survive given how many people there are right now?

Awwwww... you're just a big, softy, optimist at heart!

As I understand it, ( and that's a very limited degree ) , tachyons cannot be created under normal circumstances, because it would take an infinite amount of energy. So you can't take ordinary matter, and produce tachyons, even at Cern.

So it's not just the contradictions of time travel and causality that are a problem with faster than light particles, it's relativity itself that's going to be threatened, if the neutrinos ARE going faster than light.
Because they certainly didn't use an infinite amount of energy generating them.

My camera already does this, and here's a picture of one of my cats to prove it.

Lawrence Krauss wrote an article on the Dawkins site.

The Hunting of the Higgs: what is it and why does it matter?

Well worth a read.

“First, the short answer:

If the Higgs is discovered, it will represent perhaps one of the greatest triumphs of the human intellect in recent memory, vindicating 50 years of the building of one of the greatest theoretical edifices in all of science, and requiring the building of the most complicated machine that has ever been built. That’s the good news. But if the Higgs is all that is found at the LHC, it will mean that the other crucial empirical guidance that physicists now need to try and understand truly fundamental questions about our existence—from understanding whether all four forces in nature are unified in some grand theory, to determining what may have caused the Big Bang—will still be absent. Answering these questions may be beyond our technical and financial capabilities in this generation.

Now for the long answer:”
