after it expands it will implode, making a massive explosion. wow.

The idea of a "Big Crunch" ending the existence of the Universe, has pretty much been thrown out the window.
Scientists discovered that the Universe is no only expanding, but it is speeding up. The theory now, is that the Universe will simply fade out, as all galaxies get further away from one another.
Personally, I don't really agree with that theory. It just doesn't feel right; my gut says "no, that's wrong." Call it denial, or just plain wishful thinking; but it just doesn't feel right me.
My personal theory is based on a couple of different things:
1) Newton's First Law of Motion:
Objects in motion tend to stay in motion, and objects at rest tend to stay at rest unless an outside force acts upon them
2) Everything that we know about the Universe, and our planet, is that everything recycles and/or occurs in cycles.
It just makes sense to me, that the whole Universe, would also follow these same basic priciples.
This idea can be best illustrated by the "Beziers" screen saver, for Microsoft Windows.
Just stare at it for a little bit, and open your mind. It will not only seem possible, but logical that this is actually how the Universe functions.
The way the screen saver shows this rubberband-like object (aka: Universe), it leads one to think that by these motions alone, it would be able to provide a constant source of energy.
Therefore, one could also say that the Universe is eternal, and never-ending.

If the universe crushes back, then it wil NOT release energy at all, it will absorb it all into a singularity. And implosion is the OPPOSITE of an explosion.
To find out how much energy there is, you have to figure out the mass of the universe (including the dark matter that is conjectured outweight visible normal matter by a factor of 5), convert that mass to the equivalent energy using E=mc^2, and add the dark energy which is currently assumed to make 70% of the universe...

The oscillatory universe theory was pretty much sacked in the sixties, right? The replacement, called the cyclic model is still contoversial. Dark energy may not dissipate at all, and some measurements seem to indicate the universe may not be a closed system, so a recollapse may never occur.

That will not happen. The laws of thermodynamics wont allow it.
1) 1st Law of thermodynamics: Energy can not be destroyed or created. It can only be transformed.
2) 2ND Law of thermodynamics: All things have to have an equilibrium.
3) 3rd Law of thermodynamics: All matter and existence decays into chaos.
It wont happen. Thermodynamics doesn't allow the Big Bang to ever happen.
Secondly there is no dark energy. That is made up. Energy is energy.

Sorry, It isn't going to crash back again. The big crunch is a dead theory (although beautiful).
For this to happen the rate of expansion needs to going down, but n fact it is going up. So no big crunch

Presumably, the same amount needed to create it, coz according to the Law of Physics, you can not create energy

The universe is not going to crush back together. It is going to inflate into nothing.

Isn't that like asking: How fast is that bullet going that is flying toward my head? How sharp is that guillotine blade sliding down to my neck?

You have decided the theory of the universe? Way to go!!!
