Law of Conservation of Energy.

[learnin to learn]

The law of Conservation of Energy states that energy cannot be created or destroyed.

What would happen if some how energy was created? would all life cease to be? or would there be any affect at all?

[arkain101]

Energy can not be created or destroyed it can only take on forms and change into other types. But the Net total of energy neither lessens or gains in any kind of action or reaction.

Well, if the law is accurate, it's a null issue. Basically, you'd have an imbalance.

In a electromagnet. Dos the magnetic field come from the "current" or the "wire"? .......Of course the current is the catalyst.

So nothing would really happen, there would just be an inbalance?

[Jay-qu]

but what defines a balance in the first place.. I think its a null issue, the law states it cant be made, you just cant get something from nothing. Maybe one day if we accidently found a way to get zero point energy out of other dimensions it may appear that energy is been created, but in reality it will always be coming from somewhere.

Could be argued that it's from both, as the current itself is conducted by electrons in the wire. It's interesting to see in demonstration. I took a few physics courses in college as electives, and one of my professors did a demonstration where he measured a magnetic field generated by a current passing through a copper wire. He then used magnets to generate an electric current in that wire, showing that the two forces were inseperably part of the same thing. Really cool...

 

 

Not sure what you mean about "the current is the catalyst," considering what I mention above.

[maxc]

If you have 2 coils. No.1 coil 40 gauge copper wire with a resistance 1049 ohms, 100 feet. No.2 coil you have 5 gauge wire. to get the same resistance you must now use about 3,348,000 feet for wire. Both coils you will pull .095 amps at 100 volts dc. Coil 1 will have a weak magnetic field of .012 Gauss. Coil 2 will have a strong magnetic field of about 23.7 Gauss. That's why I say the current is the catalyst. More wire stronger magnetic field.

Ok I got one. Photons that are red-shifted due to the expansion of space, by definition E=hf, will loose energy. Where does it go?

[pgrmdave]

What would happen if some how energy was created?

 

The universe would be a little warmer. That's it, really.

well it cant just disappear can it? so does it change back to potential energy?

[Jay-qu]

potential of what? doesnt seem likely. I really dont know, my reasoning may be wrong, but thats why I asked..

[learnin to learn]

its a good question!!

In general, the Law of Conservation of Energy is right. However, what recent scientists mind the meaning of "Energy!"

As an amateur scientist that just begin to study for Einstein's Unified Field Theory since 2005, I would like to tell that the universe has two types of energy are "external energy" and "internal energy."

The Law of Conservation of Energy just right when this Law is applied for each type of above mentioned energy.

In my study, "internal energy" and "external energy" has a curved relationship that scientist may use this relationship to take out energy from the universe to serve for human life.

[TheBigDog]

Could you expand on this "internal" vs "external" thing? Reminds me of Shingeo Shingo.

I was wondering the same thing

I agree that the reduction in energy (frequency) of a photon redshifted by the expansion of space (the “cosmological redshift”) can be thought of as being transformed into a kind of potential energy. In this case, I think, the energy would be transformed back into photon frequency if the expansion of space were to be reversed.

 

The problem with this sort of explanation is that cosmological expansion, which is a feature of ”inflation” theories, though many theorists believe it is a real phenomenon, is essentially an empirical one, devised to account for discrepancies between the classical (and Special Relativity consistent) ”Hubble flow” redshift model, and observation.

 

I don’t personally have a good grasp of expansion theories, noting only that there are many, some contradictory, and that they have changed considerably since their introduction in the early 1980s. The best synopsis I’ve yet encountered was the 3/2005 Scientific American article ”Misconceptions About the Big Bang”, which stated:

The cosmological redshift is not a normal Doppler shift. Astronomers frequently refer to it as such, and in doing so they have done their students a serious disservice. The Doppler redshift and the cosmological redshift are governed by two distinct formulas. The first comes from special relativity, which does not take into account the expansion of space, and the second comes from general relativity, which does. The two formulas are nearly the same for nearby galaxies but diverge for distant galaxies.

Though possible due just to my lack of understanding, I remain skeptical that cosmological expansion actually exists.
