It is the talk on the street, hate it because it is something I never learned a lot about;

I mean, these are neutrinos; ie; nothing of value.

If true, it will help us develop new theories or more probably improve old theories. Then those theories could predict something we haven't observed yet, which would obviously be of great value.

AFAIK according to the theory of relativity, accelerating to the speed of light would require an infinite amount of energy. I think you don't really need to know more to understand why this is big (if true). Hoping to take the course in theory of relativity next spring so I can understand this better myself.

If true, then basically you can throw the entire Relativity Theory out of the window and start researching about Tachyons.

Actually black matter and black energy apologists have already said that light speed was not the true speed limitation for any particle, as black energy is predicted to be what stabilizes the central core of the milky way galaxy, and that can only be achieved if there's some type of force acting at faster speeds/energy output than the light-speed "suction" gravity well from the black holes.


I think I'll keep on saying this...

OMG WHAT.

Don't mind me, I'm just reading too much Science lately >___<.


That sounds like speculative cosmology mixed with fringe physics and new age philosophy to me.

I find it curious that you use those terms to characterize the current state of Hawking's theory on Black Holes and quantum leaks tied to anti-gravity effect from dark matter. 

I find it curious that I haven't heard Hawking opposing the very fundamental General Relativity but you claim the opposite.

Also, by ''Black'' you obviously mean 'Dark'.

I didn't say that he opposed the very fundamentals of general relativity now did I? I don't claim anything, so I will strongly reccomend you to read Science Magazine, July 2009 and March 2010, they're both very easy to find. Plus, Hawking's March 2009 conference in Dean Howard's USC College is the basis for the aformentioned articles I'm talking about.

Yes, I did mix up Dark energy in my initial post, though that's of no consequence, as it's a simple noun mix-up.

Reasonable on 23 September 2011

sorry to be pedantic, but unless I'm reading the press releases incorrectly the situation is simply that the light speed barrier "might" have been broken. This is science, and until the results can be re-produced multiple times and independently confirmed then nothing has been proven yet.

I mean, it's exciting news, but nothing has been proven yet.



Try to be reasonable... its easier than you think...

I personally am skeptical about the whole idea of achieving infinite energy.

I'm studying physics in the university. Does this mean my syllabus will finally change after so many decades?

isn't subatomic concerned with quantum physics

that way it was already known as black holes could absorb light

there wasn't any evidence thats all

If it is true, and I do not believe it is, it means that we can signal backwards in time.

In relativity, moving faster than light is directly equivalent to moving backwards in time because from certain reference frames events will be in the other order.


Errr. No.

I'm doing a physics degree. I think that's correct.

Edit: So much misinformation in this thread I can't begin to respond to it all.

Let me make it a little clearer:

 

''If it is true, and I do not believe it is, it means that we can signal backwards in time.''

Err no.

 

Because, if it is true then the conditions of Special Relativity are broken which means you can't use SR to begin with. Unless you only want to accept the theory partly, but then who are you to choose which parts are to be accepted and which not?
