How to make/create energy ?

Thank you :smile:

 

[mystic07]

energy can neither be created nor destroyed, it can only be converted from one form to another . (from the law of conservation of energy)

If energy cannot be created then how it came into existence ?

For the same reason what you cannot create gold, and gold exist.

Hope this doesn't turn into one of those moronic perpetual motion machine discusions. I still can't believe that some people in 2010 still think that perpetual motion is real.

The total energy in the universe (all universes) is zero – nothingness ..

This issue is nicely described in both books by prof. Stephen Hawking, “A brief history of time” and “The grand design” (Stephen Hawking/Leonard Mlodnikov) ..

google and you will find them ..

The search for perpetual motion is something that is repeated again and again in electronic forums and I am not surprised.
If I am surprised that there are people still believing that the Earth is the center of the universe.

you are right....

Let us hope that at least one form of perpetual motion exists...
That of the earth free falling through space - because if it stops....
:sad:

Einstein modified the law of conservation of energy.

According to Einstein the Total Sum of Mass and Energy in the Universe is constant.

So if you want you can create energy out of mass. This is what happens in nuclear fission and nuclear fusion reactions.

Are you sure that energy and mass are different ?

A very scientific test:

Tell you what - I'll smack you across the head with some energy
and then I'll smack you across the head with some mass
and you can decide if they are the same?

You can't create energy... It is the law of conservation of energy...

 

[123jack]

just to keep things a bit current...

energy/mass can indeed be created
it seems out of nothing at all

by "nothing at all" I do mean nothing at all.
(That is perhaps the hardest concept here)

Whether we could ever have any influence over that
and how it relates to the apparently outdated "law" of conservation
is a far more interesting debate I suspect.

You cannot create energy. For that matter, you cannot create any thing. Energy can only be transformed from one form to other.

 

[123jack]

I refer the honourable gentleman to the answer I gave previously ;-)

 

[djsfantasi]

Ahh, but whose "nothing" is it? There's the rub. What is nothing to you or I may indeed be very real to another "observer".

This is like a political argument...it is going no where. Quit replying and kill this thread!

think this right. so energy can generate from other product transfering.

My understanding of the spontaneous creation of mass/energy is that it
requires a total absence of everything. The vacuum of ordinary space for instance is nowhere near good enough - and yet this stuff just "pops up."

I agree the first question is "where from?" but the math seems to suggest the answer is quite specifically "nowhere" leaving the answer to your question as "there can be no observer"

If only the LHC was bigger :twisted:
