Yer another time traveling claim

Re: Yet another time traveling claim

"Another possibility, is to use laser power instead of magnetic repulsion. A very powerful microwave laser (a maser) on the ground could be aimed at a mirror upon your ship, and the momentum of the maser beam would propel the ship upwards."

the only reason i dont like this idea is: gravity will still affect this device. so instead of fighting gravity, id rather use it.
 
Re: Yet another time traveling claim

sorry for all the posts, i just wanted to state one thing:

"At any rate, keep in mind that no form of space propulsion is capable of breaking the light barrier. Travelling at light-speed requires an infinite amount of thrust"

but thats the point! it will always have infinite thrust, gravity will always pull it, and in space there is supposedly no drag
 
Re: Yet another time traveling claim

On the OP's prediction of Hillary's presidency. If she's that great in those four years, how could she possibly lose that next election? When's the last president, who the majority thought was great, lost reelection? Unless his opinion doesn't/didn't reflect the majority? I used to think it was impossible for her to win, but lately I can just feel it's going to happen, somehow, someway.

That may be. However, thrust must be applied gradually. An non-exhaustable source of thrust only means that your vehicle would accelerate indefinitely. You'll get closer and closer to the speed-of-light, but you will never quite reach it. Reaching the speed-of-light by mere acceleration is a physical impossibility. It isn't a technical problem, but a fundamental limitation in the universe we live in. To accomplish the "impossible" feat of light-speed travel, a completely new approach must be needed - a method which does not rely on "acceleration" at all.

There also seems to be another problem with your idea: Gravity is not affected by electromagnetic forces. No matter how strong your magnet is, there is no reason to believe that it will affect the gravitational field of the earth. Gravitons (the particles which mediate the force of gravity) are not subject to the electromagnetic force. In other words: you can't "bend" gravity with an electromagnet.
 
Re: Yet another time traveling claim

thats pretty close to my original idea. my plan was to pave every road in the world with a highly magnetic mixture, and have cars that float, you could even have propulsion by simply changing the angles of the magnets.

This may very well work. It might even be possible to do this without special roads. You see, all matter is a little magnetic. Ordinary roads are no exception. So if the magnet on the car is strong enough, the car will float on an ordinary road as well.

You will, however, need a computerized system to control the magnetic field of the car. You will also need to find a way to create a portable magnet capable of a flux of at least 10-20 Teslas. And you'll also have to find a way to shield the computer (and the passangers!) from the magnetic field.

It can be an interesting project - inventing the first true hovercar. It won't travel through time, though.

"In other words: you can't "bend" gravity with an electromagnet."


i think theres a way around that.
 
Re: Yet another time traveling claim

how much power do you think it would take? im guessing 1kw/hr or more

I have absolutely no idea. You'll need an engineer to answer such a question.

At any rate, power is measured in kW, not kW/hr. Sorry for being picky, but the units do matter.
 
Re: Yet another time traveling claim

how come an electomagnet picks up things? it can free a paperclip from gravity, but it cant lift itself?

i was under the impression that negatives and negatives always push away from each other, and positive and a negative attract.

i believe that with a sensitive enough program, it could lock on to a certain point and use the earths gravity, or the moons, or whatever is nearest.


its all a dream really, as it would take millions of dollars in funding, experiments out the wazoo, and then i'd have to learn alot more about magnetic fields.

but i do believe that magnetism will be a big part of the future. imagine a skyscraper that was magnetized, wouldnt have to worry about that building too much. or houses in tornado alley, they would be able to stand much more.

also, at the north and south poles, a compass spins like nuts, so why dont we make a giant generator to harness all that free energy?

in my humble opinion,magnetism will be very important in the future.

The next guy or woman that comes along to run against her must have better bullshit to feed the public.

Just like Bill did when he ran against Bush Sr.

I am still not convinced she gets elected. If she does not get elected, many of these so called time travlers are full of it.

A magnet cannot "free" a paperclip from gravity. It simply provides a force in the opposite direction - an electromagnetic force. So now there are two distinct forces which are at tug-o-war: gravity which pulls the clip down, and the magnetic force which pulls it up.

So while you CAN propel a ship with magnets (at least in principle), this is no less "fighting gravity" then using any other form of propulsion. The magnet, just like rocket engines or the laser power of STARWISP, is still in a tug-o-war with gravity. There is no avoiding this (at least not with 21st century technology).

And like any other form of propulsion, the magnet too has limitations. The magnetic force between two objects gets weaker as the distance between them increases.

Dreams are good. The world is practically made out of the dreams of great men.

And you are right. The key to converting dreams to reality, is knowledge. You should learn not only about magnetic fields, but about mechanics in general. First you'll want to learn about Newton's three laws, and about how forces and energy are measured. Do this before you even begin to study magnetism, because these are the concepts you'll use throughout your work, and without them nothing will really make any sense.

Also, look for popular science books which give lots of numerical examples. Not calculations, mind you, just figures that will give you an idea of the measure of things. How small is an atom? How large is a galaxy? How much energy is released from a pound of coal? A pound of uranium? A pound of antimatter? What happens to ordinary matter if you heat it to a temperature of 1 million degrees? 1 billion? 1 trillion?

Look for as much examples as you can. The more extreme - the better.

I fully agree.

Magnetism has lots of potential (technical pun intended). From hover-cars, through chemical detection devices, to defense applications (defense against both man-made weapons and natural disasters). Magnets can also be a great source of fun: levitation rides, upsidown twister, and magnetobot battles.

But, I highly doubt that magnetism will play a major role in relativistic space travel and/or time travel. These things require incredible amounts of energy. Relativistic space travel requires energies of the order of mc², or 300 trillion joules per ounce. Time travel requires energies approaching the Grand Unified Scale, which is about 100 trillion times higher still.
 
Re: Yet another time traveling claim

im trying to get into an online college. hopefully that will help /ttiforum/images/graemlins/smile.gif

"Relativistic space travel requires energies of the order of mc², or 300 trillion joules per ounce"

holy cow! well, back to the drawing board /ttiforum/images/graemlins/smile.gif
 
Re: Yet another time traveling claim

It's funny how decorporealization is now a word.

I am here posting at my pre-determined time, pointing out that Hillary is all but a dead lock as the next Prez, as foretold by Titorian, against all logic when originally posted.

Wow!
 
Re: Yet another time traveling claim

BUT.....games not over....Clintin has 1180 delegates....Obama 1189. If he wins, I guess, that means the BS flag goes up for certain?
 
Re: Yet another time traveling claim

I would like to formally state that Titorian is deceased.

(Standing ovation)

Titorian was DOA upon his first post here and on every other site he posted on. The problem was that he was the only person existent that didn't realize it.
