Default Spaceship Could Fly Faster Than Light

I thought of this idea 15 years ago. Someone is just seeing the light? My idea involved a shield of some sort that would keep space/time still inside. Slightly different, still the same concept.

Quote:
Travel by bubble might seem more appropriate for witches in Oz, but two physicists suggest that a future spaceship could fold a space-time bubble around itself to travel faster than the speed of light.


We're talking about the very distant future, of course.


The idea involves manipulating dark energy — the mysterious force behind the universe's ongoing expansion — to propel a spaceship forward without breaking the laws of physics.


"Think of it like a surfer riding a wave," said Gerald Cleaver, a physicist at Baylor University. "The ship would be pushed by the spatial bubble and the bubble would be traveling faster than the speed of light."


In theory, the universe grew faster than the speed of light for a very short time after the Big Bang, driven by the dark energy that represents about 74 percent of the total mass-energy budget in the universe. Dark matter constitutes 22 percent of the budget, and normal matter (stars, planets and everything you see) makes up the remaining 4 percent or so.


Strange as it sounds, current evidence supports the notion that the fabric of space-time can expand faster than the speed of light, because the reality in which light travels is itself expanding.


Cleaver and Richard Obousy, a Baylor graduate student, tapped the latest idea in string theory to devise how to manipulate dark energy and accelerate a spaceship. Their notion is based on the Alcubierre drive, which proposes expanding space-time behind the spaceship while also shrinking space-time in front.


String theorists had believed that a total of 10 dimensions exist, including height, width, length and time. The other six dimensions exist largely as unknowns, but everything is based on hypothetical one-dimensional strings. A newer theory, called M-theory, suggests that those strings all vibrate in yet another dimension.


Manipulating that additional dimension would alter dark energy in terms of height, width, and length, Cleaver and Obousy theorize. Such a capability would permit the altering of space-time for a spaceship, taking advantage of dark energy's effect on the universe.

"The dark energy is simultaneously decreased just in front of the ship to decrease (and bring to a stop) the expansion rate of the universe in front of the ship," Cleaver told SPACE.com. "If the dark energy can be made negative directly in front of the ship, then space in front of the ship would locally contract."


This loophole means that the spaceship would not conflict with Einstein's Theory of Relativity, which states that objects accelerating to the speed of light require an infinite amount of energy.


However, the Baylor physicists estimate that manipulating dark energy through the extra dimension requires energy equivalent to the converting the entire mass of Jupiter into pure energy — enough to move a ship measuring roughly 33 feet (10 meters) by 33 feet by 33 feet.


"That is an enormous amount of energy," Cleaver said. "We are still a very long ways off before we could create something to harness that type of energy."


The workaround solution may leave fans of Einstein pleased. But for now, faster-than-light travel remains, like Oz, a pleasant fantasy.

You should have written it down, now they stole it.

I think it is. I mentioned it at one time I think in this GT forum! I'm gonna look.

Similarly, some fecka pinched my idea for a stargate

Neal will love that, Subsim goes down in history, they will study our postings a thousand years from now.
I will be famous also.

Yeah yeah yeah! At least my idea was plausible!

By the way, I take pride in the idea that I was right! Thats all I care about.

Can't find it. I wonder how far back the records go? Probably 2005 time frame I would guess.

Doesn't matter. We won't need this type of travel anyway - not with Cern able to make Micro Black Holes in the near future. With this kind of power, you just fold space time and warp the otherside of the universe to you, and you simply take one step over - one step, one instant in time, you travelled billions of light years in a single moment.

I guess its probably a good idea to know precisely where you are going though.

A vehicle could do this.

One peice of the puzzle is the Z machine: http://www.sandia.gov/media/z290.htm

Ya know? I was thinkin about your said Stargate. Suppose there is a collider in there, and they create micro black holes, and use it to do something similar to the above of stepping across the Universe? Maybe the Stargate idea has merit! :p

Pfftt! Still not as fast as SUZUKI Hayabusa

Wanna bet? That Z-Machine is also faster! It can accelerate a plate from 0 to 76,000 MPH in 1 second! :p We haven't even begun to talk space time folding!

Beat that on your bike! Even with that ramjet looking thing hanging out the back!

Here are something for you to think about:

Faster than light Look at this image subman1 has in his first posting

That would be impossible

I say that you will not be able to see becasue light(what your eyes sees) goes faster than your eyes can take input from.

that's my theory

Here we go. This may be old even, so they may be in 6 digits by now!

Zero to 76,000 mph in a Second

By Leonard David, LiveScience Senior Writer
posted: 07 June 2005 11:13 am ET


Scientists at the Sandia National Labs in Albuquerque, New Mexico have accelerated a small plate from zero to 76,000 mph in less than a second.



The speed of the thrust was a new record for Sandia's "Z Machine" - not only the fastest gun in the West, but in the world too.



The Z Machine is now able to propel small plates at 34 kilometers a second, faster than the 30 kilometers per second that Earth travels through space in its orbit about the Sun. That's 50 times faster than a rifle bullet, and three times the velocity needed to escape Earth's gravitational field.


The ultra-tiny aluminum plates, just 850 microns thick, are accelerated at 1010 g. One g is the force of Earth's gravity. Doing so without vaporizing the plates was possible because of the finer control now achievable of the magnetic field pulse that drives the flight.


Z's hurled plates strike a target after traveling only five millimeters, or less than a quarter-inch. The impact generates a shock wave -- in some cases, reaching 15 million times atmospheric pressure -- that passes through the target material. The waves are so powerful that they turn solids into liquids, liquids into gases, and gases into plasmas in the same way that heat melts ice to water or boils water into steam.


One purpose of these very rapid flights is to help understand the extreme conditions found within the interiors of giant planets in our solar system. By creating states of matter extremely difficult to achieve on Earth, the flyer plates provide hard data to astrophysicists speculating on the structure and even the formation of planets like Jupiter and Saturn.



Didier Saumon, an astrophysicist at Los Alamos National Laboratory, noted that the internal structures of Jupiter and Saturn are composed mostly of hydrogen. So knowing its equation of state -- how hydrogen and its isotopes behave at pressures from one to 50 million atmospheres -- is highly relevant to how scientists infer the interior properties of these planets.



An upgrade of the Z Machine is planned for next year and is expected to achieve higher plate velocities.

How can you say what light would look like there? You must remember that your time and space is slowed down to normal inside the bubble. So maybe you see the traces just like that as it slows to enter your time and space? Think about it.
