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.

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.

 

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.
