How can 9 x10^16 joules of energy be converted into a mass?

Question

Preferably Gold atoms

Answer 1

Individual subatomic particles have been created from energy in particle accelerators, but nobody has a way to make large amounts of a chosen substance. By the way, 9 x10^16 joules is 25 billion kilowatt-hours and would convert to one kilogram of mass. At 10 cents per kilowatt-hour that would cost $2.5 billion dollars. The price of gold is only about $20,000 per kilogram, so that would be a bad deal even if you could do it.

Answer 2

Why do you want to convert so much energy into mass when we on Earth are facing energy crisis? even if you managed to do that, the mass would be so huge that you yourself would not be able to hold it.

Relativistic Physics (as someone else has written) consider both mass (m) and energy (E) as equivalent (i.e., one can be converted into other) at the speed of light c=3x10^10 cm/sec. However, the present day Physics allows us to convert mass to energy and we will have to wait for further advancement to see your wish fulfilled.

Answer 3

We have the ability to convert mass into energy but not the other way around (yet). Until we have Star Trek technology, you'll have to wait.

Answer 4

Campbelp2002 had the right idea - sell the energy, then buy gold.

I think that answers your question quite nicely - it is possible to convert energy to gold!

Answer 5

equivalent mass can be calculated E = mc^2 but that is just equivalent mass. What that mass is can not be specified. It would show up as the simplest elementary particle.

Answer 6

I usually use a really big set of wood clamps and some Elmer's glue.
