How does a magnet work? I mean honestly.

Lemme do a quick Google reasearch ...


Nope...the moon has no molten core, yet has a gravity pull to it...I believe it's simply to do with mass...more mass, more pull...my penis pulls chicks towards me! :D

I have to agree with those posts. Newtonian physics only works reliably once you know your datum. If you are discussing the very nature of your datum, *poof* ...there goes Newton rolling over in his grave :freak:

Now this force I want more of!!!!!!!!

But speaking of mass being an attractor... Where does that endless supply of energy come from. It can't be simply be
explained away by saying something is big and therefore
it has a specific gravity. It has to have a power supply to
continue its work.

After a quick 30 second or so research ->

The questions about the origin of gravity get blurry to me after looking at other planets. We aren't even sure if Saturn has a core ( surface ) at all! And Saturn's gravity is holding onto 34 moons ... :eek:

What is holding all those gases and liquids together?


Hey - mabe all planets are really weak black holes that gathered enough material to form into what we now know - and the constant force of the hole pulling is our gravity?:idea:

Awesome!

We're at the 'Towers AAs' on Sat night. And I'll be butchering Whitesnake, Ratt, Accept and Pantera solos until 2AM. :o

Looking forward to meeting you!

Hence Hawkings attempts at the Grand Unification theory relating sub-atomic physics (stuff developed by Einstien, Schroedinger, Bohr, Heisenberg et al) and Newtonian physics. Which are quite different, and sometimes seemingly incompatible.

 

Quantum physics is a strange land.

No discussing datum here... Just facts...There is nothing in Newton

Laws of the universe...if we could tap into that energy it would never cost anyone a penny to use it...

 

Nothing is endless...they say the universe will collapse on itself one day when it's done expanding...then will there be a new beginning? ...where will that energy come from, to create another big bang?

Freakin' DEAL!!!!! I look forward to it too! Hope ya don't mind a 45 year old unabashed 80's music lover there...lol

What'll be in the area the current universe is in, once it starts collapsing?

 

Do ya think a pilot in space could ever run into the edge of the universe?

I think this question will never be properly answered unless we understand and know how the universe was really created. There are any theories, most popular being the Big Bang Theory obviously, but even that has come into question recently. To understant the energy flow in our solar system, we have to relate it to the energy flow in our galaxy and the entire universe, and only then can we arrive to a conclusion which wholistically takes into account all the universal variables ever existant. Unless we reach that far back into history and outer space, all we're left with is theories.

You've got some points a bit confused I think.


The correct definition of work is "a force moved through a distance". By that definition, a magnet sticking to a fridge is not doing any work at all since no motion occurs, and can thus stick indefinitely [ignoring loss of magnetism which occurs due to completely unrelated processes].

 

 

I honestly don't think I have anything "confused".

 

Physical labor typically involves moving heavy objects or material from one place to another. The heavier the object and the further it is moved, the more energy must be expended in the process. The Work Function is merely an attempt to describe this fact using a simple equation

I watch NOVA and all those science shows...I love that stuff.


I have a DVD set called Stephen Hawkings World...about newly discovered galaxies, trying to explain black holes, radical new evolution theories...

 

 

I really must grab one of his books! Inspiring stuff.

The electromagnetic force is far far FARRRR greater than the force of gravity. Also, "Energy is a measure of being able to do work.[1] This is a fundamental concept pertaining to the ability for action. In physics, it is a quantity that every physical system possesses. This quantity is not absolute but relative to a state of the system known as its reference state or reference level. The energy of a physical system is defined as the amount of mechanical work that the system can produce if it changes its state to its reference state; for example if a liter of water cools down to 0

Yes sir, good point. I apologise for that post as it may seem a bit patronising, but I never imagined this thread would be going into such deep levels of scientific questioning.

 

 

Neither did I honestly... But there are so many holes in every theory that is is unreal. Science does not seem to be interested in exploring the holes in Newtonian Physics. They don't explaining why Newtonian physics is still used by our space program today while all but completely ignoring Einstein's General Relativity Theory. It seems to be completely at odds with Newton's theory and yet not one scientist seems to question why one works for one thing and the other for another set of circumstances. I am in a complete quandry.

No offense, but what makes you an authority on the direction of science and what scientists think?
