Good find, Comiso and quite interesting. I think because the computers of today get more and more powerful, they can run calculations and formulas that were once impossible, or would take a very long time. Plus with the simulations and modeling that can be achieved because of the processing power, I think we are on the age of some big discoveries.

That would be nice.....here we are, sittin in the future, and I'm still waiting for my flying car!!!

According to Einstein's theories, as speed approaches the speed of light, relative mass increases toward infinity(simplistically). So to make it to the speed of light, infinite energy would be required. Therefore, the speed of light cannot be obtained, thus not exceeded. I think!

The General Relativity Theory would require an 'infinite universe' to attain the Velocity of light, as attaining the velocity of light requires a divisor approaching zero ------------> requiring an infinite quantity of energy which is not available in a finite universe with finite mass.

The more interesting question may no be "how fast may we travel in our space-time continuum" , but "will we be able to travel to distant locations in this space-time continuum far faster than light travels over a period of time?"

Monstrous Gravity Wells like Black holes raise the theoretical questions of 'worm hole' connectivity between such masses (like perhaps from one Black Hole in one galaxy to another - or others - in a different Galaxy/Star sytem)

There is no theoretical approach for a vehicle or surviving approaching the Event Horizon, but supposing an artificial 'black hole' could be theoretically constructed (and safely contained) as part of a stellar vehicle, could it be designed to create a constant singularity that a.) links with other singularities, and b.) maintains a 'relative time' throughout the transfer (i.e Not pass 2 millions years into future during this 'trip0)', and c.) be able to navigates back to desired Space-Time locus?
 
I remember seeing something about using electromagnetism for propulsion.

I do not believe if you go faster then the speed of light you go backwards in time but forward. IIRC ignoring the issue with mass if you had a spaceship that went the speed of light, what would seem like minutes or hours on the ship would be eons on earth (not sure of the exact time but something like that)

In the 'vehicle' approaching the velocity of light, perception of relative time lapse within the vehicle approaches zero while the observing frame of reference (i.e. your twin brother on Earth) perceives Newtonian time passage as normal.

The travelling twin brother, while travelling near light speeds perceives his trip at those speeds as a 'blink of the eye' while the brother on Earth dies of old age as well as all the kids, grandchildren, etc - depending on how far the light speed vehicle travels in Newtonian Space-Time. When the vehicle slows down the perception and experience of time within the decellerating vehicle more closely matches the external Newtonian frame of reference..
 
How about first flight with a 20kW fuel cell on 7 July. With twice the efficency of a piston engine from tank to propeller, a motorized glider has achieved 44% efficiency. A range of 466miles at 105mph, the motorglider's only emission is water vapor. This was accomplished by the Antares DLR-H2.

Like Joe Haldeman's time-travelling soldier William Mandella?

William Mandella - Wikipedia, the free encyclopedia

I haven't read these books, but they are essentially an investigation of the phenomena that Bill just explained. FTL travel throws up some huge questions - even if it is possible, what will it do to human beings and human societies? Even long-distance sub-light travel throws up a range of human and social issues that will have be dealt with alongside the scientific ones...
 
now this just when above my head..tried to read some of it and got stuck with the tie fighter.. math and physic was never my stronge side.. :?: so i just say.. go tie fighters :twisted:

That rings a bell - can't think of the title of the top of my head, but it was definitely Heinlein, and there have been similar stories coming out ever since. The Forever Wars were part of that movement
 
I am not a physicist but maybe one should circumvent the speed of light. If one can bend light, one should perhaps look at folding light/space and just step through to your destination. I am sure the "skunk works" have more than they let on.

Gravity driven vehicles. Getting rid of the tracks for maglift trains is probably just around the corner.
 
Hi,

Bahhh, the speed of light is just another barrier we'll have to break. We did it to sound, so we can do it to light.

For pete's sake... if we can't beat the speed of light then how are we going to effectively find other inhabitated planets and wage war on them. :)

There is no natural implication that simply because we broke the sound barrier, we will one day break the luminal barrier, or whatever it will be called. Relativity had no say in exceeding the sound barrier but it will have plenty of say in FTL travel (or information transfer). With the benefit of hindsight, exceeding sound was merely appropriate aerodynamics coupled with a powerful enough engine - that will not/can never be enough to exceed light.
 
Heh. 100 years from now, somebody's gonna be having a discussion on whatever they use for forums (telepathy, perhaps?) and say "with the benefit of hindsight, exceeding light was merely ____and____ coupled with _____. That can never be enough to exceed ____!" :lol: They also said man would never fly. Or walk on the moon. Tell someone (especially a group of scientists with funding) that they can't do something, and they'll do it just to prove you wrong. Humans are like that.

**slithers off to communicate with mothership**
 
If you believe that scientists are destined to find a loophole in GR theory that allows faster-than-light travel, I've got a design for a perpetual motion machine that I think you'll wanna invest in.

BTW, there is not, nor ever was, a sound 'barrier'...

The idea behind an ion engine is that high energy gases are stripped of there electrons and then shot out to create some sort of force, using Newton's 1st law of motion to get the ship to go somewhere. Of course this is nothing like a TIE Fighter that uses ion engines to manuveur like an earth bound fighter jet, rather its a version of propulsion like rockets.
If you are familiar with the movie and book 2001: A Space Odyssey the spaceship Discovery uses a nuclear powered ion drive. It is noted that Discovery is the fastest ship to be ever created by humans yet still takes about two years to reach its final destination.

To answer your question concerning the speed of light, it is impossible to break the speed of light. Einstein's theories are exact and revolve around the fact that light will always reach its target, making it possible to travel relatively faster than the light photon. However the speed of light 3.0x10^8 is attainable, but you are not actually outrunning light.
It is possible to cheat the speed of light to produce a similar effect. The newest and most accessible theory to this is made possible by a sub-atomic particle called tachyons. Although I don't understand the math behind them, tachyons have an imaginary mass (i-mass) allowing them to travel faster than the speed of light. If any ship were enveloped in a concentrated tachyonic field it would allow the ship to travel faster than light.
Other universe hoping theories include creating a gravitational singularity strong enough to bend space time. Imagine folding a paper in half, the distance from each side has no shrunk considerably. Theoretically this is also possible in space, by bending space with a gravitational field. We can also use worm holes apparently. However this is all speculation.

Nothing is impossible. It just take a group of determined people working together toward the same goal.8)

Aaron, read my post
nobody said it was impossible, I pointed out that exceeding the trans-sonic threshold does not imply that we will do the same to any trans-luminal threshold as a matter of course.

My main point in that post is that we WILL NOT do it with appropriate aerodynamics and a nice, big powerplant.
