Boundless Energy: What's the Answer? | Earth & Space

[linux kid]

I was wondering...what's a form of energy that we know of that is boundless both on Earth and in space?

Could you please express your question in more detail? I don't know what you're asking.

After doing a little reasearch, it appears that magnetic fields are present in all of space. And based on this, I would like to know is there another form of energy (other than magnetic fields) that are present in all of space?

 

[Danger]

Magnetic fields cover a lot of different aspects, including the background microwave signature and starlight. There are virtual particles everywhere, and gravity extends forever even though it becomes pretty much unnoticeable at any significant distance from the source.
That's about all that I have to offer. One of the cosmology dudes will be a better source.

Magnetic fields are not a form of energy.

OK. My other question about magnetic fields is: are magnetic fields susceptible to friction?

 

[chroot]

No.

are magnetic fields susceptible to friction?

No.

...which got me wondering about particle accelerators. Those tubes in which they accelerate particles must be damn near a true vacuum, are they not?

They are. Particle physics machines employ some of "highest" vacuums (i.e. lowest particle densities) on the planet.

wait, why isn't radiation energy? One more thing, do energy have any shape of size? If it doesn't, does it atleast some kind of region it covers?

Yes, radiation is a form of energy.

I have no idea what you're asking.
