Theory for traveling in space?

Question

Do you ever do lazo thing like cowboy?
Well the system is if we have a mirror like far far away and think we if we have it around the galaxy?
Then human spacship has a magnet laser shooting at this mirror thing. will the spaceship move?
The laser magnet are just fantasy and who knows mybe other will find solution for this magnet laser fantasy.
Remem it is just a theory..............OK.

Richard R are you Einstein every science makes mistake?
And many scientist polute the earth form chemical waste to and other staff maybe you should share some of your idea or fantacy if you hae one?

Answer 1

How about this one smartguy,
Suppose we could travel faster than the speed of light which is approximately 186,282.397 miles per second. Could we give the finger to the moon, Jump in our space ship and go to the moon, set up a telescope and look back at earth and see ourself giving the finger to ourselves?

Answer 2

I think what you're asking is if a laser can be used to drive a spaceship. The answer is...maybe. A laser is made of light that is all of one wavelength and lined up (or collimated). Because the waves are lined up with each other, they constructively interfere. In other words, the crests reinforce the crests, the troughs reinforce the troughs, and the amplitude of the entire wave increases.

Light can transfer momentum, despite its lack of mass. A photon (or packet of light) has a certain amount of energy. Energy is just another form of matter (as per Einstein's famous equation E = mc²), so you can use the energy of a photon to figure out its mass equivalent. Knowing the mass equivalent and the speed of light (300,000,000 m/s), you can calculate the amount of momentum transferable from each photon. When a photon strikes a mirrored surface and bounces off, the momentum transfered is doubled, since the surface must not only STOP the photon's forward momentum, but give it momentum in the reverse direction. So, if you strike a mirrored surface with enough photons, you can indeed push it forward.

It's not a very fast acceleration, though. Regardless of how energetic the light you use is, you still only get a tiny bit of momentum per photon. The benefit is that the spaceship's mass can be kept relatively low, since it won't have to carry the propellant needed to accelerate itself.

Will it ever be a reality? I don't suppose anybody knows, but the theory behind it is sound.

If that's not what you were asking, I apologize. It was a little hard to tell.

Answer 3

Magnets have nothing to do with lasers and lasers are not magnetic. Shooting a beam of laser light at a mirror would not make a space ship move. Anyway, how would you get the mirror out there in the first place? In some other kind of space ship? If you had a space ship that could put a mirror out there, just go everywhere in that space ship and forget about the mirror.

Answer 4

If you reversed the role and place of the mirror and the spaceship this would work --in theory at least.

Put the mirror on the bottom of the spaceship and set the laser on the surface of earth and shine the laser on the mirror. The spaceship will slowly move away from the earth. Keeping the beam focused, and providing enough power will be engineering problems, but it would work.

Space tourism is the recent phenomenon of individuals paying for space travel, primarily for personal satisfaction.

As of 2007, space tourism opportunities are limited and expensive, with only the Russian Space Agency providing transport. The price for a flight brokered by Space Adventures to the International Space Station aboard a Soyuz spacecraft is now $30 million. Flights are fully booked until 2009.

Among the primary attractions of space tourism are the uniqueness of the experience, the thrill and awe of looking at Earth from space (described by astronauts as extremely intense and mind-boggling), the experience's notion as an exclusive status symbol, and various advantages of weightlessness. The space tourism industry is being targeted by spaceports in numerous locations, including California, Oklahoma, New Mexico, Florida, Virginia, Alaska, Esrange in Sweden and Wisconsin, as well as Singapore and the United Arab Emirates. Some use the term "personal spaceflight" as in the case of the Personal Spaceflight Federation.

Answer 6

A theory is based on fact or scientific observation. You have presented a science fiction idea, not a theory. Since it is just imagined, there can't be any critique on it being right/wrong.

Answer 7

You disgrace the name THEORY. Your fantasy is utter gibberish. Do us all a favor and stay away from the science boards.
