Einstein Doesn't Know It All!!!

299,792,458 meters per second. According to Einstein, the speed of light is the fastest speed that can be possibly achieved according to his theory of relativity. In the 1940's, the whole science community and basic science revolved around this theory and for the past six decades, our "scientific truth" has arisen from Einstein's theory. This theory was thought to be true and so all continuing scientific discoveries following, assumed that what Einstein said was true.

Until September 2011, the speed of light was the fastest speed of travel according to science. In Switzerland, at a particle-physics lab in Geneva known as CERN, there was an experiment performed known as OPERA (Oscillation Project with Emulsion-tRacking Apparatus). The summary of this is pretty much that a beam of particles was shot 730 kilometers away to a lab, Gran Sasso National Laboratory, also collaborating in the project that was located in Sasso, Italy. Thinking that the beam was meant to be received at the the speed of light, surprisingly the beam was received sixty nanoseconds too early. There a speed faster than the speed of light! The experiment used a long-baseline neutrino experiment to measure oscillation. The scientists were able to create and design a machine to detect something faster than the speed of light, which is the speed of neutrinos!

There is now a significant change in the modern physics model and in the change of current/future scientific discoveries. Faster than light travel has now been proven  and in result particles can move at greater lengths in seconds, where at the speed of light it'd take thousands of years. Reaching farther galaxies is now up for grabs and neutrinos aren't affected by the way everything else is in the visible universe by time.


With this new discovery, scientists are now thinking that long ways in the future, time travel may be very real as well as an attainable possibility. Back to the future anyone?

Really interesting post! I never thought it would be possible to travel faster than the speed of light! I was a little bit confused about what a neutrino is, so I looked it up for anyone else who reads the post! Check it out! And who knows, maybe we will be able to time travel - how cool would that be?!

Just another reason why we must continue to fund science... we don't know everything, and everything that we do know is most likely wrong. Almost everything in the world is based on Einstein's many findings (And before that Newtons) Learning that there is something faster than light opens up many possibilities, but also reminds us that what we know is always changing and that we still don't know everything.

Here is an interesting article on the complexities related to a "normal" object trying to move at the speed of light What they essentially say is that as you approach the speed of light, the objects mass increases exponentially, as does the energy required to move it. Not being a physicist, I don't know how the particle fits into all of this, but still an interesting article when thinking about a spaceship attempting to reach that speed.

That is very cool! It just shows how little we really know about the universe. The problem with believing in science, is how often it is unproven. For example we only know where about 4% of the universes weight comes from. This could be the result of the hypothesized dark matter and dark energy, but it could also be because the laws of physics that we believe to exist are untrue, and we've still got a lot to discover.

Great post. Ofcorse like most people I zeroed in most on the topic of time-travel. It made me remember the article in my SATs which was about why Steven Hawking doesn't believe we'll ever achieve time-travel, if it is possible for that matter.

One of the more interesting reasons for his believe is the lack of time-tourists having visited us, infact he held a party inviting time-travellers and didn't send out the invitations until after the party, noone showed up.

While I was unable to find my SAT article online, I found one where Hawking discusses the issue during an interview and claims " I have experimental evidence that time travel is not possible." Definately worth a read.
