Traveling faster than the speed of light -

Quote:
For generations, physicists believed there is nothing faster than light...

But in an experiment in Princeton, New Jersey, physicists sent a pulse of laser light through cesium vapor so quickly that it left the chamber before it had even finished entering.
.....

Ultimately, the work may contribute to the development of faster computers that carry information in light particles.

Dark is the absence of light. So dark moves in when light moves out. The speed at which light moves out is equal to the speed that dark moves in.

Speed of dark = Speed of light.

"Quatermass and the Pit" was the 3rd installment of the Quatermass British Triligy, named in the USA as "5 Million Years to Earth" 1958 is about a dying Martian Colony finding the earths atmosphere not for martians. I seen this movie as a child and was fasinated by it, I've owned the DVD OAR 1.66:1 wide screen anamorphic for many years now. Look it up on the Internet Movie Data base @ www.imdb.com under the title "5 Million Years to Earth", it was a good yarn for the british who made it in B & W, in the USA Quatermass 3, AKA the title above was made in color.

P.S. Mary Shelley Dr. Ronys assistant was also cast as "The Medusa", a woman who could turn men to stone after looking at her. Mary Shelley is/was an actress not the book writer of "Frankenstein" by author Mary B. Shelley, wife of the poet.

Intel want to get strange cpu designs out be 2012. That's when hp's transistor will go into production capacity too.

It'll take them a bit, but that's when the funky cpu's come out. Maybe longer to put them into notebooks.

But we'll never see pc's go to the speed of light. Man isn't perfect, so the production to do those cpu's/Programs(A.I) will never be possible by man.
Nothing is impossible. It's simply not within our grasp - yet.

there are some things that are CURRENTLY not possible... but given enough time and research can happen. Yes, computers will eventually work based on light. No really, I'm serious. They are already doing research on the quantum level where transistors switch light instead of electricity, believe me, you are not the first to think of this. Google it, i'm sure you'll find something on some research someone in some university in cali is doing. The technology wont come around for at least 20 years in a practical sense, but from what i've heard / been taught, silicon is on its way out the door when it comes to new processor fabrication, and in about 5-10 years new materials are going to be used / developed in order to keep Moore's law going. Silicon is reaching its physical thermal and electrical limits, and silicon based transistors can only get so small before they start breaking down and not working. So yea, in short, computers are gonna be freakin fast in a few decades

Extending Moore's Law

Here's the latest from Intel... computers running at the speed of light!

"Scientists from Intel have achieved a major advance using silicon manufacturing processes to create a novel "transistor-like" device that can encode data onto a light beam. The ability to build a fast photonic (fiber-optic) modulator from standard silicon could lead to very low-cost, high-bandwidth fiber-optic connections among PCs, servers and other electronic devices, and eventually inside computers as well."

"Intel has promised computing at the speed of light after using standard silicon manufacturing processes to create the world's first continuous wave silicon laser."

Im not sure I know what the difference is between terrestrial and celestial quantum mechanics. I think the same laws apply, ironically, universally. Matter and a vacume should not change the way the laws of physics are applied. It should only affect whether or not there is a relevatn body or dimension that can be affected, though some things are truly universal, in despite of the presence of matter or energy.

Light speed computing is an imposibility and something we see every day, as paradoxical as that is. On certain organisms, light is translated into visual data at near or exactly the speed at which it hits the retina or whatever optical element is relevant here. Ligth speed computing in a technological sense cant really be acheived, as far as processing goes, currently, since theres no way to code information in light and have it be translated into different functions in the same way electrical impulses are. Maybe someday...

There was one movie called K-Pax, when they Kevin Spacey(Prote) in a planetarium on Chapter 6 they asked for a demonstration of the speed of light, he said addios and aloha they said when are you going I already went and came back."Back were I come from that's called the fastest gun in the west routine but I am not from your area". They then asked him to map out his planetary system and he had their jaws litterly dropped, doing the whole thing from memory. When asked what he could tell them about the speed of light he said nothing, you would probably blow yourselves up, you don't what power is in a particle of light.

Yeah that actually WAS an entertaining movie.

DewrGleision: Speaking of the laws of physics, in outer space some laws do NOT apply. A straight line thru the universe will actually curve back upon itself, due to the nature of the universe - and the curvature of space. Einstein theorized that if you could travel to the end of the universe, you'd be looking at yourself, since you'd effectively have bent space AND time. That was his theory on time travel. Furthermore, astronauts in space are actually aging SLOWER than we do on earth - by only a few milliseconds, but still. The further you get away, the greater the fluctuation. Also, dark matter, while never seen, measured, or anything, is known to exist - yet all our physics tell us it's impossible.

In short order, there's a lot we DON'T know. Once we begin unlocking those secrets, of course computing will get faster.

The speed of most electrons in your computer now is nearly at the speed of light already.

According to my research. The cache that makes computers a possibility, the core of computers. Is the questionmark.

Cache is lines created from memory.

Physics doesn't know if quantum physics is a wave or a line. A plane or a line.

In other words. If the cache is a plane. It'll meet resistance that causes friction/heat. And there's problems. Not so for lines, it'll slide right through.

In my opinion. We're looking for the skinniest plane. How do you define lines, points and planes. It's impossible. So if we're looking for the skinniest plane. We're hunting for the impossible.

So what's impossible is the epitamy of the future technology.

Edit. If light speed is the future of technology. It's impossible.

All laws still apply. A "straight" line only curves back on itself if the universe has positive curvature. Current observation shows that it seems to be very flat. Astronauts in space age slower only due to their speed relative to us. Also, because they are further from earth's graviational well than we on earth are, their clocks will run a little faster, i.e. strong gravitational fields cause clocks to slow down. I'm not sure which effect is greater since I've only studied special relativity, but I'm guessing the speed effect is greater since they aren't that much further away. Our physics doesn't tell us dark matter is impossible... it simply doesn't explain what it is. There are several candidates within the current theoretical framework, some involving particles that haven't yet been seen in accelerators like supersymmetric particles, or other very small, non-luminous bodies.

Exactly, computers already work near the speed of light. Software, on the other hand, does not...

Let me answer those comments individually:

1. The universe is NOT flat. Research supports this. (Excerpts from Universe is Uniform on Large Scales): "General Relativity describes gravity as a warping or distortion of space and time near a massive object. In General Relativity, four-dimensional spacetime is curved. You may want to refresh your memory of these concepts by reading the Relativity chapter." (Excerpts from Cosmolgy): "The universe does not have to curve back on itself as shown in the illustrations above. This type of closed universe is usually easier to picture, but the curvature could be the opposite. In an open universe the universe curves away from itself. A two-dimensional analogy would look like a saddle. The angles in large triangles would add up to less than 180°. Like the closed universe, there would be no centre on the surface and no edge."

2. Time in space: (excerpts from Einstein, Relativity, and Time Travel): "Einstein laid the basis for most modern theory on time travel in 1905 when he developed his special theory of relativity. This theory predicts that time passes slower for moving objects than for stationary ones, a phenomenon termed time dilation." ... "For example, an astronaut who spends 53.4 days in orbit, upon returning to earth is younger by a millisecond than he would be if he had never ventured into space." ... "But if a traveler were to travel into space and back to earth a distance of 1000 light years, traveling at 99.995% the speed of light, they would have aged only 10 years while 1000 years had elapsed on earth."

3. Dark matter: (excerpts from Dark Matter Exposed): "Dark matter makes up about 23 percent of the universe's mass-energy budget. Normal matter, the stuff of stars, planets and people, contributes just 4 percent. (The rest of the universe is driven by an even more mysterious thing called dark energy.) A small portion of dark matter has already been identified and is no longer mysterious. Tiny particles called neutrinos, once thought to be massless, are now known to make up a sprinkling of the total dark matter column of the budget. Cold dead stars, recently found to be plentiful, also contribute modestly to this accounting." ... "Researchers no longer wrestle with whether it exists or how much there is but instead can focus on its properties, Perlmutter said."

So you are correct on that, but we just can't explain what it is or where it comes from.

1. The statement that the universe appears to be flat on large scales is different from spacetime being curved locally. The curvature of the universe at large depends on the energy density of the universe. Again, current observation shows that the density parameter of the universe is very close to 1, leading to 0 curvature. I'm an astronomy/physics major, I know what I'm talking about.
2. As I mentioned in my previous post, time dilation due to traveling at high speed is different from sitting in an intense gravitational well. Read up on general relativity.
