Speed of light travel
    #5294786 -

http://www.physorg.com/news10789.html

On Tuesday, Feb. 14, noted physicist Dr. Franklin Felber will present his new exact solution of Einstein's 90-year-old gravitational field equation to the Space Technology and Applications International Forum (STAIF) in Albuquerque. The solution is the first that accounts for masses moving near the speed of light.

Felber's antigravity discovery solves the two greatest engineering challenges to space travel near the speed of light: identifying an energy source capable of producing the acceleration; and limiting stresses on humans and equipment during rapid acceleration.

"Dr. Felber's research will revolutionize space flight mechanics by offering an entirely new way to send spacecraft into flight," said Dr. Eric Davis, Institute for Advanced Studies at Austin and STAIF peer reviewer of Felber's work. "His rigorously tested and truly unique thinking has taken us a huge step forward in making near-speed-of-light space travel safe, possible, and much less costly."

The field equation of Einstein's General Theory of Relativity has never before been solved to calculate the gravitational field of a mass moving close to the speed of light. Felber's research shows that any mass moving faster than 57.7 percent of the speed of light will gravitationally repel other masses lying within a narrow 'antigravity beam' in front of it. The closer a mass gets to the speed of light, the stronger its 'antigravity beam' becomes.

Felber's calculations show how to use the repulsion of a body speeding through space to provide the enormous energy needed to accelerate massive payloads quickly with negligible stress. The new solution of Einstein's field equation shows that the payload would 'fall weightlessly' in an antigravity beam even as it was accelerated close to the speed of light.

Accelerating a 1-ton payload to 90 percent of the speed of light requires an energy of at least 30 billion tons of TNT. In the 'antigravity beam' of a speeding star, a payload would draw its energy from the antigravity force of the much more massive star. In effect, the payload would be hitching a ride on a star.

"Based on this research, I expect a mission to accelerate a massive payload to a 'good fraction of light speed' will be launched before the end of this century," said Dr. Felber. "These antigravity solutions of Einstein's theory can change our view of our ability to travel to the far reaches of our universe."

More immediately, Felber's new solution can be used to test Einstein's theory of gravity at low cost in a storage-ring laboratory facility by detecting antigravity in the unexplored regime of near-speed-of-light velocities.

During his 30-year career, Dr. Felber has led physics research and development programs for the Army, Navy, Air Force, and Marine Corps, the Defense Advanced Research Projects Agency, the Defense Threat Reduction Agency, the Department of Energy and Department of Transportation, the National Institute of Justice, National Institutes of Health, and national laboratories. Dr. Felber is Vice President and Co-founder of Starmark.

Same reason I didn't comment on the story... however, the word 'beam' sounds very odd in a non-optics related physics paper.

Not enough to understand that... at least in the paper they are called fields rather than beams...

The article is bunk, but the paper is not. The article actually makes the paper sound like pseudo-science, but it most certainly is not. The paper is a bit over my head, but from the parts that I understand, sounds very interesting.

I should ask one of the Physics prof's around here if they know anything about this, or if this guy is a total crackpot.

Maybe I'll do that later today after class.

Yea I can understand that paper. Its amazing our first order approximations can be that off. I await the other paper however, as that sounds a bit more enticing, at least from the propaghanda.

well, i studied a bit of partical phys. in a prior life. so:

using the word 'beam' really just concerns a directed field. doesn't even need to be directed energy in the case of a laser or microwave overn or whatever. but say gravity, which as a field an not an energy. there are few concepts to be noted. first, the article mentions it, but it takes exponentially more energy to increase you speed the faster you go. if you are already travelling at 270000 km/second (%90 lightspeed) it takes something like as much fuel/energy to get to %91 percent (%1 faster) as it did to get to %90 in the first place (roughly).

using the word 'beam' is a way of communicating to layman various fields on the subatomic level. we are all familiar with gravity, but there are other forces like 'strong force' and 'weak force' (physicists are not know for creative naming) that are like gravity but hold the little bits together in the universe. interstingly these forces actaully 'work' faster than lightspeed, or instantly. example, if a new planet were to just pop into existence in the solar system, 1 light year away from earth (for example) you would think, since _nothing_ is supposed to go faster than light, it would take one year for the gravitational pull to reach to earth and effect us. when actaully, that 'field' or 'beam' of gravitaional pull INSTANTLY starts pulling on its surroundings, be they 10 feet away or 10 light years away... these forces work around lightspeed and it gets a bit hairy as to how.

ANYWAY, his idea is really nothing new. it would require more energy than can be imagined to pull a 'star trek' and go from 0 to warp speed in 1 second. low and slow is the way to go. if you were to apply a constant force, an engine accelerating at nice and low rate, but constantly, you speed would gradually increase to lightspeed. with constant acceleration, it will take longer and longer to go a few km/h faster the faster you are already travelling. might take 5000 years to get up to speed, and another 5000 to slow down, but it is doable. you really never would 'cruise' at a speed, you'd speed up and up and up, then start breaking halfway to your destination. he is proposing using 'free' (not fuel required) energy from fields of celestial bodies to slowly and steadily get up to speed. still will take a human lifetime to get even a fraction of the way there. same idea is used on 'solar wind' conecpts. letting the force of photons (light) and such emmitting from the sun catch on a giant sail, and slowly get you moving. infintesimally small amount of force, but its free and in space there is no resistance so you dont need much to get going/break surface tensino. there is none. read: it would take FOREVER

NASA/JPL has an engine they have used for a few years that is very startrek. its called an ion engine, and it basically is a plate of copper that emits ions out the back (emits a cool blue light too). it only provides thrust pressure equivilant to the weight of a sheet of paper in ones hand, but it uses almost no fuel, and can run for years on a liter of xeon gas. acceleration is painfully slow, but the price/performance ratio is nice. it is used in some of those comet chasers as of late. takes months to get up to 100km/h, but in another month you are at 1000km/h, another month 10000km/h, 100000km/s

right, nice long, no one will read it anyway...

Balderdash! You studied particle physics, you don't find the nomenclature of subatomic particles creative?  Beauty, charm, color, strangeness...  Then there's the eight-fold way.  Gluons...

People just don't give physicists enough credit these days.  Ever since Feynmann kicked the bucket we're just a bunch of smelly geeks in wheelchairs.  :tongue:

hell no it's not just people wheel chairs...  sure, Mr. F was engaging, but so is Leon Lederman, a handful of authors that can deliver the concepts to you low and slow, but most importantly, with wit and charm.

physics is one of those last frontiers that really has no boundries.  i mean, we can learn everything there is to know about a resus monkey, even simulate its brain on a computer eventually, but there always seems to be a smaller, single 1 dimensional point in space kinda particle just over the next gigajoule.

its the closest thing to divine mystery if ever experienced...  oh christ it gets me excited...  i was young and wide eyed round the time neutrinos and higgs bosons were all the rage.  i think it was the end of highschool and the director of Argon Labs came to the physics class for a lecture...  ended up chewing his ear off and it was just so invigorating... years later i just have come to terms that i don't have the computation skills to deliver the goods... concepts, yes, skills in application, i dunno...

(since its 5:40am and i cant sleep) one of the other great mysteries in my opinion is bio chem/life science stuff.  everyone argues about how life got here...  no primordia ooz, none of that.  i just was reading some papers on how metabolizm came before orginized cellular structure.  apparently, all you needed is 11 atoms, maybe a lightning strike, and walla, you have various 11 atoms componds competing for resources, give it a lot of time, and you have more complicated competing structures, that eventually will over power the competition.

like multi-spore mycelium! :smile:

eventually these compounds organize, then RNa, then life...  peachy.

it's all about the big questions, nothing else holds my attention...
