A Wrinkle in Time

[nissangirl74]

Do this scare anyone else? I think the ramifications could far outweigh any benefit.

The new research builds on recent demonstrations of "invisibility cloaks" that can make objects seem to disappear by bending waves of visible light.

The idea is that, if light moves around an object instead of striking it, that light doesn't get scattered and reflected back to an observer, making the object essentially invisible.

Now Cornell University scientists have used a similar concept to create a hole in time, albeit a very short one: The effect lasts around 40 trillionths of a second.

"Imagine that you could divert light in time—slow it down, speed it up—so that you create a gap in the light beam in time," said study co-author and Cornell physicist Alex Gaeta.

"In this case, any event that occurs at that instant of time won't lead to scattering of light. It appears as if the event never occurred."

Call me crazy but.

Making Time Stand Still

To conduct their time-stopping experiment, described this week in the journal Nature, Gaeta and colleagues aimed a laser beam at a probe and passed the beam through a device called a time lens.

While a conventional optical lens bends a beam of light in space, the time lens modifies the light's temporal—not spatial—distribution.

"It's a way of being able to really control the properties of a light beam in the time domain, and shape and distort and do funny things like this to light in the time domain," Gaeta said.

Study co-author Moti Fridman, also of Cornell University's School of Applied and Engineering Physics, devised a method in which he crossed the laser beam aimed at the probe with a strong "pulse" laser inside specialized fiber optic glass.

"This changed the frequency and wavelength of the beam so it moved at a different velocity, and this is why a [time] gap was created," he explained.

A second pulse laser on the other side of the time hole reversed the changes, restoring the beam to its original properties.

In the experiment, an event that happened inside the time hole wasn't detected by the probe.

It seems like they may accidently come across a way to hold the light and let it build up then modify the frequency which could possibly be refined to cut things with just plain light that has been modified and stored then suddenly relased.
I would love to learn more about the "time lense".

Do you agree??

Wow! Cool Stuff! I have to read more. One of my current books that I am working my through is the one by Brian Greene on Parallel Universes - totally fascinating going so far: http://www.amazon.com/Hidden-Reality-Pa ... 489&sr=1-1

I dont quite understand. Ive always had issues about time, Its hard for me to think of it as a fabric like I do space. I guess I need an image to better understand. How do you speed up a photon if its already traveling at light speed? Ill try and read this again when my head is clearer (car pissed me off royally earlier)

[carloslebaron]

Who said that "light" and "time" are the same?

Light is just what a body expells like the Sun or any chemical reaction, this is to say, a perceptible event, by naked eye or by special sensors.

Now, do those idiots...excuse me, do those scientists have percived physically the presence of time to creatre such an argument?

Without any factual evidence of such an existence of time, the only thing those scientists are observing is how light behaves in front of such new "environments" and how machines sometimes detect such behaviour and sometimes they missed.

In reality, time is no more than a measure, like weight or longitude, so, the whole thing in such link is just garbage...the measure called time cannot be warped by light or anything else, time is just tic tic tic given by your watch or by the atomnic clock (the atomic clock works with the same principle: the recptor senses 9,192,631,770 vibrations of the cesium atom and sach! makes a click...one second to go...after other 9,192,631,770 vibrations of the cesium atom and sach again! the clock makes another click...)

There are no sensors preceiving any passage of time because time is not a physical entity...period.

[alms24sebring]

I guess I was sci tracked with the time lens that was mentioned not that they are related, but no you are absolutely wrong in that time doesnt change. Time is measured but it can change and come close to stopping as you approach light or circle a very massive object. As you fall into a blackhole, time goes slower to the observer and possibly stops, but thats a whole nother theory. GPS satellites correct the billionth of a second in their time relative to the Earth from circling the planet. Otherwise GPS locations would be many miles off. Im pretty sure weight is physical too. And of course we cant see a longitude line but we can suremeasure it. Just because we cant touch it doesnt mean its not there, same goes for time.

[carloslebaron]

Wormholes, black holes, warped time, pure fantasies...

Did you really pay attention to the words of the dude of the link you have provided? He says that "HE BELIEVES" that time existed before the big bang and suych and such...

I think that you can watch the video hundreds of times and no evidence of its existence is given in the video.

Look, do yourself a favor, go a search online the discovery of the existence of time, and come back with the information about the date, the scientist name,and the instrument used to detect such a physical existent time.

Please, another favor, stop using links that are nothing but fantasies portrayed as if they were science, because the video you were watching starts with the big bang, an event that is solely a hipothesis, in other words, you have nothing solid to prove that time exists physically.

Best wishes.

[alms24sebring]

Ok great of course we can probly never prove whether time existed or not before the big bang. I never said they proved it. It just gives an idea of what time is whether it is truly real or not, and provides a possible experiment to prove it. Obviously you dont watch the show but its one of the greatest ones that brings incredible evidence of everything that we thought was not possible. In the passed 100 years dreams and fantasy HAVE become reality in physics, especially with black holes, which are positively 100% real. Are you serious about that?? Nothing is a dream anymore, scientists expect anything and are still surprised when anything remarkable or thought impossible comes up.

Heres a good mind f***.

"and provides a possible experiment to prove it"

A posible experiment to prove it?! Ha ha ha ha....

How long you guys will keep lying to the common guy of the street with your "though experiments", "possible experiments", "future generations will make it true" and etc, etc babblings?

Did you read the tittle of this section here? It says "Science!"

What you and the dude from the video are talking is fiction, imaginations, pure fantasies, nothing real, nothing proved as fact.

For rhis reason, the whole. complete, total Relativity is nothing but pure crap, because time has never ever been proved as something physically existent, and by consequence the observations of clocks slowing are nothing but malfunction of the clocks when are exposed to acceleration and or similar environments other than the one where they were originally calibrated.

Show me black holes pulling space...show me black holes pulling light,,,show me black holes evaporating (as Hawking claims -what an idiot!), you have showed nothing, no one has ever proved such characteristics with real observation but stupid suggestions that something is messing with some stars in such and suchfar away location in space...but in reality you have nothing to show but silly computer simulations,videos like the one you showed in your last reply, where no facts but the beliefs of a dude is the main subject, also pictures which can interpreted in anyway other than black holes...sorry but you are not talking sicience here, because the difference between science and beliefs is that science provides facts...and you lack of facts...otherwise...show me time as existing physically, and only then...never before...your words will mean science.

Cheers.

I wonder what YOU consider to be "science", then?

[alms24sebring]

Wow dude you really just went there. I let the last 2 posts in this and other threads slide but that post just pissed me off man. Forreal, how dare you disrespect Einstein and Hawking by continuously calling them and all scientists idiots. YOU DONT EVEN KNOW WTF YOUR TALKING ABOUT!!! How do you think we are so technologically advanced in this day and age? Here's a hint, it wasnt f***ing Unicorn magic and pipedreams from the hand of god. IT IS CALLED F***ING SCIENCE! Who says theories cant be real, predictions have been proven countless times.

Do you really think that experiments are meaningless?? Do you know how many concepts have been developed and sought after to understand the universe by experiments? Your posts mean nothing to me anymore. I dont even want to read them because it angers me so deeply. We are giving you proof and common knowledge of all things about time, except actually what time because it is still unsure if it does actually exist at all as a fabric as I have said. We are not there yet in the technology. Christ, do your own research if you think the scientific method is a farce. Show me evidence of ehat you have read. From what your telling me Im surprised you even know what a chemical reaction is. Next you'll claim that mathematics is a pointless game of checkers and that water turns to wine by looking away. Math tells us everything and these "idiots who dont know what they are talking about" have changed the world with their brilliant minds. Like I dont even know where to start by chewing your a$$ out right now Im so pissed.

Here, go here:

Create an account and I DARE you to post the s**t you have been saying to these guys and tell them that science isnt real. I am no actual scientists but these guys are. They will show you what the Universe you live in really is before they all destroy you and your feelings. I know many of them have huge online libraries of information. Get the d!ck out your vagina and be sure to pm me the thread you start so I can sit back and enjoy your humiliation. GTFO

[AppleBonker]

(as Hawking claims -what an idiot!)

[alms24sebring]

You know what Im sayin!! Like wtf is that.

[carloslebaron]

alms24sebring, what really is p*ss*ng you off is that there is not a single evidence that time flows or exists as something physical, and by consequence such a dilatation of time is nothing but pure crap.

I challenged you to provide the required evidence of such an existence of time as something other than just a measure like weight or longitude, and you have failed miserably.

If you were right, you should have filled up this thread with tens, perhaps hundreds, or maybe thousands of links supporting the detection, evaluation, perception, meassure, whatever of such a physical time, but you have nothing.

On the othyer hasnd, I can assure you with simple observation that clocks are devices calibrated to a regular functional work: tic tic tic...even atomic clocks are calibrated this way, to make tic tic tic as regular bases. There is not a single sensor inside the clocks to perceive any passage of time, but clocks are devices like the toy bunny of the battery's add hitting a drum :tum tum tum... See? that bunny IS A CLOCK...tum tum tum...tic tic tic...

You send the toy bunny to outer space and its regular functional work will suffer a variation...exactly as the atomic clock does.

As you can notice it, all that farse of Relativity and dilatation of time must be discarded for good, because such crapped idea of a flexible time subjected to the speed of objects or gravity of bodies is to mix the dumb fantasies of Einstein with the seriousness of science, and this farse must end. I encourage you to be part of the restoration of science as a branch of knowledge where reasoning with experience must rule over imaginations, conjetures, beliefs, etc.


Cheers.

[alms24sebring]

Dude wtf, I just dont think you even have an idea of what Relativity is. The reason why icant explain through your tiny head is because it is hard for me to put it in words. I dont fully understand it. Relativity is not physical but its a theory of how time dilates with speed. There is also such thing a length contraction. Lets say you are at a train station and a train passes you at light speed. The train is going to be longer and you can accurately find out how long by Einsteins equation. I wish my Physics teacher was here to explain to you, of course you would probly just laugh and call him an idiot too without even listening. I would take the time to go through my notebook and try and explain to you with the simple equations but I wont waste my time on it for someone who will just throw it back in my face.

Relativity is used in determining distances, speeds. GPS, and time dilation in fast moving particles, along with many other applications. Its fact, get over it. It has been proven that time slows down as you get close to light speeds. Nothing travels faster than light (that we know of). The 2 atomic clocks do vibrate at 9 billion whatever times per second, but not relative to one another. God why do I even try anymore

Edit: heres some quick stuff. All you have to do is type "theory of relativity" in google.

For someone who professes to be smarter than everyone else, you sure don't communicate very clearly.

I suppose my next question is this: If you're so well-informed, why isn't someone paying you for your vast scientific insight?

Don't worry. I am guilty too - it is difficult to ignore such irrationality.
