How was the great amount of energy first trapped inside 'the atom'?

Answer 1

Nothing to do with gravity.
The nucleus at the center of an atom is held together by the strong nuclear force, this force is totally unrelated to gravity or anything electrical/magnetic.
For reasons far too complex ( and mathematical ) to go into it turns out that it takes more force ( = energy ) to to hold a big nucleus ( = heavy atom ) together that it takes to make 2 mid sized ones. It also takes more force to hold 2 small atoms together than 1 slightly bigger one.
The upshot of all this is that splitting a big nucleus (E.G. uranium) into 2 parts releases the excess energy. Joining 2 small atoms (E.G. hydrogen) also releases energy.
Just incase you are curious the point where joining small atoms or splitting large atoms stops releasing energy is iron.

So to answer your question the energy was 'trapped' as the nucleus of the atom formed, it is an intrinsic part of what makes the atom.

Answer 2

The gravitational potential inside the atome is=G * M/r=C^2.The Energy trapped is what keeps the atoms apart other wise they would freeze and contract to their minimal space.

Answer 3

How do the stars do it? The answer is that, owing to the enormous amount of matter in a star, stellar gravitational fields are tremendously greater than those of planets like Earth. Despite the very large speeds of a star’s material particles (great heat amounts to great particle speeds), the enormous gravitational fields contain them to the volume of space occupied by the star. Under such conditions such super-speed particles on collision courses regularly get close enough together (before slowing to a halt) for the short-range nuclear forces to engage and for fusion to occur.

Such fabulous gravitational fields do not exist on Earth, but other means of containing the molecules of "super-hot" plasmas long enough for fusion to occur have been investigated for quite some time. Unhappily progress has been slow, and only limited success has been attained. The only terrestrial cases of fusion power have been thermonuclear (or "hydrogen") bombs!

Answer 4

THE "BIG BLAST" THAT CREATED THE WORLD GENERATED THE ENERGY THAT BECAME ENTOMBED IN THE ATOM. WHEN SPLIT, THE ATOM RELEASES THAT
TRAPPED ENERGY.

Answer 5

science doesn't have the answer to that.

doubt it ever will because its too long ago.

science seems really solid from the outside, but look a bit closer and you can see that science doesn't have all the answers.

Answer 6

Nuclear. radioactivity I think
