I have no idea. I figure you can hit light speed once and then its lights out.

Light Speed

I think maneuvering would not be so difficult except you would have to think way, WAY ahead of the craft; might want to put it on auto-pilot.

I see Hubble telescope almost reached the edge of the visual universe. Matter at that distance is nearing the speed of light. I think science has located the center, or at least the general direction, of the "Big Bang." Red shift shows that matter acceleration diminished at a constant rate do to the gravitation grid, but then began to accelerate from some unknown force beyond the viewable limits. The cause has something to do with dark matter.?

So at the micro level (sub atomic) we have quantum jumps that might have access to an alternate universe (String Theory) and at the macro level huge chunks of matter are traveling at very close to light speed which might blink out once they reach that speed.

I think reaching near light speed is doable but I figured it would take at least six months at 6G's for a probe to get there (probably an error in calculation). Hubble also found a Jupiter size planet in another Galaxy (anything smaller is undetectable with current technology). Spectral readings can indicate if a planet has the right elements to support life.

Fuel is the draw back. How fast can we send a probe with current technology if we were to dedicate everything to abtaining speed? Cassini reached about 70,000 mph. EagleRJ mentioned ion propulsion.

I gotta get back to work.

186000 miles/second: it's not just a limit. It's the law.

No, actually, it's still just a theory.

Einstein would be rolling over in his grave right now at all this.

G force Gravity

Einstein would be rolling over in his grave right now at all this.

He might have missed on his light speed theory but The Unified Theory of Gravity and Relativity seems to be holding true. There are two distinct forces Boson [strong, weak, colour, electro-magnetic and gravity] and Fermi [kinetic mass].

The range of force in the Boson class do not affect each other but do have an effect on Fermi which has something to do with mass weight.​

​

Science is beginning to learn that the collection of Boson forces are really the same force and that energy/matter might be convertable. That is matter might be made of energy. All new research in SUPER STRING THEORY​

Ummm...I'm not sure that there's much compelling evidence out there that he 'missed' on his ideas regarding light. The only thing I can think of off the top of my head that he 'missed' was writing off the cosmological constant.

As for the rest, I'm not sure of the relevance. Other than giving people a small taste of a random topic in undergraduate physics, what are you trying to say?

 

[ThomasR]

Never mind.

What are you trying to say?

Were you just trying to stop the post or do you have something to add?

What nation will lead in booster rocket technology?

How will the International Space Agency distribute technology?

What will happen after the Hubble project ends?

What will be the hot job prospects facing your kids and grand kids as aeronautics transitions into astronautics?

How will NASA [government] interface with civilian space projects?

Who will be the leading figures in space sciences: medicine, psychology, engineering, mining and exploration, orbital platform technology, land base moon development, space tether project, etc.?

From the feedback on this forum we, as a group, are pretty ignorant of where aviations is headed even in light of the fact that the president issued a mandate for specific goals in space exploration. NASA has been a catalist in creating many jobs in almost all areas of human endeavors.

I think there should be a greater degree of interest; and when evidence suggesting that Einstein might have been wrong in one of his speculations and a new theory which allows anwers to other suggestions he made but could not prove deserves recognition [Super String Theory].

I have already admitted I know little about these things but there was some involvement by others I was attempting to explore.

So I ask again; what is your intention?

Wasn't trying to stop the postings at all. As I see it, there are two main threads here. One revolves around progress of technology and science, and the benefits of that progress. And the other involves moving faster than the speed of light. At this moment, the two are mutually exclusive. Our fastest space vehicles are currently tens of thousands of times slower than the speed of light.

I'm open to a debate about the speed of light, and will talk string theory all you want, but at this moment in time, neither are really relevant to science being put to practical use, such as new booster technology, etc...that's all I was saying.

But not mutually exclusive. If light speed were believed to be the limit then techology efforts woud develop in areas related to non light speeds. But since there is serious speculation that this is not the limit, techological research will delve into probabilities of attaining those speeds. It might be only by amping electronic impulses to create a signal or carrier wave but the efforts will be directed toward the belief that it is possible.

If you can cut through sub space with electrons reaching tens of thousands of light years in a single direction in a nano second that would be a huge break through in spase exploration. Humans have been emitting electro-magnetic waves for only 60 years. That puts our maximum range of influence in space to 60 light years. Not really very far.

If you can debate String Theory it will be one sided because I really don't understand it. If you can explain any of this suff I am all ears.

The last understanding I have regarding NASA is that they are abandoning building vehicles and consentrating on training peronnel to build the space platform. Testing phases for the space tether have begun by developing research on manufacturing nano carbon tube fibers.

Civilian firms might be a likely source for space vehicles. Russia has the market on building high payload boosters. The Chinese are interested in getting into the International Space community but it is unclear what area of research they are competing for. The European Space Agency is research Moon development [Cemetaries, Resort Hotels, Moon Base Landing Complex, Engineering Testing Labratories and Permanent Bio Labs plus housing plats for station employees].

Once these things open up there will be a huge surge in new career fields. You or I won't benefit from any of this but our children will be the explorers and settlers of new worlds. Am I the only one who is excited about this stuff?

[Flyingdutchman]

WOW!!!!

This isn't easy reading after a few beers.

But it does bring up another question.
How do you navigate at the speed of light?

And what if you have a few of those "ships" flying around at those speeds; how does your TCAS work?
Hmm, I remember myself asking similar questions when flying a C-152 looking at a Piper Arrow..

Hehe,

Cheers buddy!

Check your PM..

Ok, I'm a tard, but if you are talking about acceleration and the imposed G-forces, how do they apply in space. If Gravity comes from a mass, what would hold the body back from accelerating without a strong gravity field pulling on it?

Gravity and accelleration have the same effect. Once you stop thrust then you become weightless in open space. Speed is relative and separate from gravity or accelleration. Two objects traveling at 35,000 mph next to each other in space have 0 speed in relation to each other. The theory is, however, that one of the objects cannot move away from the other or toward the other faster than light speed (186,278 mps) without distorting time/space. Time space is the medium we all live and move in.

New research indicates that we might be able to traverse the time/space medium into an alternate dimention or parallell universe or out of this medium into some connected medium. String theories hold up this hypothesis plus provide answers to many more previously unexplainable events.

If you are interested in current research String Theories are the newest in physics. If any body can explain it I would be interested.

Objectives

The president set a series of objectives in space exploration. Here are some videos related to those objectives. I believe that if society is to live in peace it will not come as a result of government dictates or religious efforts but through the mutual interest and cooperation provided by science.

I hope this thread never dies. If it does it means the very people who launched our imaginations into space have lost interest in their own profession. We are aviators, space science is our creation.

Explaining any kind of string or superstring theory is pretty well impossible via a message board. I can write words until I'm blue in the face, but the real beauty is in the math, and math can't really be conveyed here. If you don't already have a good background in field theory, go get one! Field theory is awesome, awesome, awesome, and at the moment, far more rooted in reality than string theory is. Here are some reading suggestions:

If you want a good overview of some of the cool things going on in modern physics without getting mired in advanced math, check out Fearful Symmetry by Anthony Zee. Very very good book, and I highly recommend it to anyone with an interest in physics.

If you feel pretty strong in math and want to learn the nuts and bolts about field theory, check out Quantum Field Theory in a Nutshell, also by Zee. This book is the real deal, and is in my mind the best *single* book written on fields. It's also a great springboard into strings, as he discusses how the concepts in the book (such as Kaluza-Klein compactification) laid the foundation for string theory.

If you're dying to get as comprehensive a look at Field Theory as you possibly can, you can do no better than Weinberg's The Quantum Theory of Fields. There are three volumes. At this point, you're hard core. It's incredibly deep and detailed, but you'll pay for the knowledge with countless late nights working through the material. Weinberg is something else. I took quantum mechanics from him in college, and he's simply on another playing field (which kinda made it hard to learn from him, but oh well). Fortunately, he writes better than he teaches in front of a chalkboard.

And finally, if you feel you have a good grasp of the Field Theory and want to jump into strings, I'd go with Polchinski's String Theory, Volumes 1 and 2. I've only worked with the first one, but I hear good things about the second one (superstring theory) as well. It's pretty interesting, although I haven't entirely bought into the theory yet. Your mileage may vary, however.

So there you go. Have fun with it!

Thanks, you are a gem. I get a bit confused spanning the gap between mathematics and physics; and then there are philosophical models that seem to have no explanation. Like you mentioned earlier, I have only a basic understanding of physics and most of what I know applies only to aerodynamic. However, aeronautics is the forrunner to astronautics and that is where my real interest is.

The president set a time line to reach Mars and many scientists believe the schedule is unreasonable. I was wondering what others might think of how well the U.S. is advancing in this field and what might be their opinions on how we will fare in developing an International Space Station.

So what effect would traveling at the speed of light have on the HOBBS?
