Back In Time or Time Travel (49)
I remember next week when I hung the washing out, thinking it was going to be a dry day, but it rained.
But, further to the Opera experiment you're on about. It seems that they may have made a monumental error. They're due to re-do the experiment later in the year.

I agree with C.I think they have made a tiny error on calculation.But also I believe that there are some places in the universe that Einstein's laws dont work and u can exed speed of light.
But even if u exed it i dont believe u can go back in time.May be God wouldnt let it happen

The proof of back in time is not possible is that,we dont have any traveller from future.
if it was posssible then people would achive it after thousands of years of evolution.then they would come back to our time bringing more technology to us which would make our world almost perfect.but we dont see that

I agree interacting is impossible but observing is very possible, we do it now by observing exploding suns millions of years ago.if it was posssible then people would achive it after thousands of years of evolution.then they would come back to our time bringing more technology to us which would make our world almost perfect.but we dont see that

16 neno seconds is still missing. the experiment itself has been repeated hundreds of times with the same result. If there is an error all good, but if there it is not, there will be great new possibilities emerging JMO------ This thread is Archived ------

yes u r right.thats the most intersting and puzzling one.would we see bing bang itself if the time,space and distance was right.paradoxal.i know.------ This thread is Archived ------
Can anything travel faster than the speed of light?
Not only possible but absolutely certain. If a car with its lights on is coming at you at 60 MPH the light from the headlights are coming at you at the speed of light + 60 MPH, by the same token if it is going away from you, the light from the tail lights is coming at you at the speed of light - 60 MPH.
The light from a distant star or galaxy can be going at +/- the speed of light depending on whether it is approaching or receding from you and this can be easily measured by the red or blue shift in the lights spectrum.
I don't worship god and I don't worship Albert Einstein either. I like to think he would be pleased by that.
There is no place in science for faith or belief or worship.
As for time travel, not possible. The reason being that time doesn't exist. It is a manmade concept.

Hi Ooby,
I would agree on your time travel theory, time isn't a tangible entity, we have created our own units of time based on the finite speed of light. ( IAU = light year )
I agree on the speed of light not being the cosmic speed limit also. Experiments have been performed on the spin of particles and their anti-particle partners. When the spin direction of one of them is changed, the other adjusts it's spin accordingly to keep in step and this happens almost instantaneously, 4 x faster than C or beyond the limit of current measurement capability. A link with string theory perhaps ?
A question about photons. Does anyone know if at the instant a photon it created it is travel at C or does it accelerate from zero up to C ?
And to get to C it must therefore have zero start mass, according to Einstein ( not mass/energy, which is a mass formed by the energy it's self ) it must develop a mass, otherwise gravity wouldn't affect it ??

You have a talent for asking questions that can't be answered easily.
Not being an astro physicist I only know what I read or figure out through logic but from what I remember there is a debate on exactly what light is ie photon particle or wave. there is evidence for both positions. The photon side says it must have mass or it would be unaffected by intense gravity. If it HAS mass, it can't go from 0 to C without passing through all speeds in between.The wave side says it must be a wave or else a laser wouldn't be possible (in a laser all the light "waves" are lined up "nestled" if you will which allows more waves to be packed together in a tight beam that doesn't spread).
Maybe it is a combo of both?
It would be nice if you could slow down light to zero, then you could put in on the kitchen table, or under a microscope, and study it.

i just cannot figure it out.Why the hell we think that if we travell faster than speed of light we can travel back in time.dont u guys think that this theory could be wrong?

Hi Rummy, from what I've read one theory goes like this. Consider space/time not to be a straight linear line but curved, curved so much that it forms a loop. Then in theory if you can travel faster than the speed of light/time you could advance around the loop and approach the images that you just left behind, from behind.
passing through their histories as you catch them up.or something like that ......

Hi EW, scientists have been shooting neutrinos at a target and detect them to be arriving just a fraction ahead of the speed of light. But the method and accuracy of the time measurement is under question.

Yeah!! But doesn´t the discovery of neutrinos and their behaviour (non electromagnetic) add to the possibility of travelling through space at great speed in the future?

My understanding is that light does not operate that way. You don't get 3 x 10^8 m/s + 60 mph. You get dopler shift and the light changes frequency (colour) due to wave compression. It will still approach you at the speed of light. Also, for you or me or a particle to travel at the speed of light, we would need to have infinite mass.

AgentAjax: In September 2011, an international group of scientists has made an astonishing claim they have detected particles that seemed to travel faster than the speed of light.
It was a claim that contradicted more than a hundred years of scientific orthodoxy. Suddenly there was talk of all kinds of bizarre concepts, from time travel to parallel universes.
So what is going on? Has Einstein’s famous theory of relativity finally met its match? Will we one day be able to travel into the past or even into another universe?
In this film, Professor Marcus du Sautoy explores one of the most dramatic scientific announcements for a generation. In clear, simple language he tells the story of the science we thought we knew, how it is being challenged, and why it matters.

Once upon a time, it was thought that Earth was flat...until Galileo proposed that it was round. It was later found to be true. Thousands of things once believed impossible, have been found to be possible.
As the video illustrates, it is mathematically possible for the speed of light to be surpassed by a neutrino. Just because we do not yet have the sophistication, or a well developed Theory of Anything, yet, does not mean there are not multiple dimensions beyond our established three.
The long and the short of it is that some Italians love OPERA, and universally like to string worms through a black hole.
