Hey, in the movie "2012" it was because of neutrinos that the world as we know it ended

$this->bbcode_second_pass_quote('Keith_McClary', 'B')ut if a body was always travelling faster than light it does not violate relativity. The problem arises if it interacts with ordinary matter.
If something is travelling faster than light in your reference frame, say from event A to event B with B later than A, then there are other frames in which B is earlier than A. If the body carries energy,this messes up causality and conservation laws.

Hopefully this is just a miscalibration of their instruments.

Humanity neither deserves nor is ready for the stars.

$this->bbcode_second_pass_quote('', 'I') do not claim that neutrinos are useless.
I claim that discovery of FTL neutrinos is useless from perspective of interstellar travel.
Completely useless in fact.

Thermodynamics is built upon time only having one direction exceeding c gives it two, there is a principle so deep in our science that it is the statement that all of our science starts with, "assume causality"; that would be broken or we would have discovered the entire activity of our universe is predetermined and cannot be changed (about the only way causality can be preserved in a ftl universe).

The Lorentz Einstein transformation for mass at speeds greater than c does not resolve to infinity, they resolve to a negative root. We have always assumed that negative root is an impossibility, but negative roots are a part and parcel of the quantum world, if it turns out they have some meaning that is attainable in the real world and that these neutrinos are a route to that......

1. Theory of relativity, which postulates (for dummies) that the speed of light is constant and cannot be exceeded, is what it is - a theory.

The situation with its introduction was similar to the OP's one - scientists observed phenomena that could not be explained by the classical Newton's mechanics, and to resolve this problem Einstein introduced the theory of relativity.

Now scientists observe a phenomenon that cannot be explained by the theory of relativity - they may well introduce another theory to deal with the new knowledge.

2. A particle traveling faster than light is obviously a very useful step forward. We may finally be able to communicate with remote destinations in outer space without much delay, be that human-made satellites or aliens or just physical objects like stars or planets. It may also somehow revolutionize our own terrestrial communications.

Perhaps a simpler explanation is that, given neutrinos are still considered to be somewhat mysterious particles, they somehow slip out of or phase out of ever our 3 dimensional brane. They wouldn't need to actually travel faster than light in a traditional sense but rather shortcut ever so slightly out of our universe. Perhaps this is also might have something to do with their seeming inability to interact with matter and to very easily pass through the entire earth without any interaction with atomic nuclei or what not.
