The universe always existed.
Conservation of Energy definition from Wikipedia: The law of conservation of energy, first formulated in the nineteenth century, is a law of physics. It states that the total amount of energy in an isolated system remains constant over time. The total energy is said to be conserved over time. For an isolated system, this law means that energy can change its location within the system, and that it can change form within the system, for instance chemical energy can become kinetic energy, but that energy can be neither created nor destroyed.

As already mentioned:
1. The universe always existed
2. An unknown force created the energy for the universe

Option 2. is breaking the laws of physics, unless a. the universe is not an isolated system or b. the force that created the energy for the universe is not affected by the laws of physics.

Here is a relevant clip of Carl Sagan

A silly question we can only ever speculate about without ever reaching any finite answers.

Regarding this one we are all on the same turf, astro-physicists, theologians, and Joe Cap at the pub. All theories.

I think the universe can be eaten anytime.

It's all a recording that gets played over and over again. It expands and contracts ad infinitum. We have all been here an infinite number of times and in an infinite number of ways. Some of us may even retain some residual memory of our pasts from a part of the universe not yet understood.
Information is never "lost" or "destroyed." Despite what Stephen Hawkings once mistakenly postulated. He has since retracted this error.

Big Bang, Big Crunch. Big Bang again, Big Crunch again. Big Bang again, Big Crunch again ... and again ... and again. That would be the easiest for me to grasp.

If there is a Big Crunch, nothing survives or reproduces. Absolutely nothing. Everything goes back to zero, then starts again.

Has anyone read the Wheel of Time series by Robert Jordan?

Personally I like that explanation.

from what i know most scientific understanding has disproved the idea of a big crunch. the universe it has been calculated is flat and could because of that go on expanding forever. we know anyway that something is speeding up that expansion, this being dark energy.

a while ago i finished watching this interesting lecture which came recommended to me. its a bit long but quite fascinating and shows that 'nothing' might not actually be nothing but something, watch it to understand.

Perhaps it's one of those time loop things. A scientist in the in the future is experimenting and trying to create a mini Big Bang in order to find out how it all worked and by doing so creates the universe which in fact destroys the current one or creates a new one. Since time and space are on in the same, time folds in on its self and turns into a small ball of energy from 14 billion years in the past. The ball explodes and the universe is created as well as the multiverse. In the multiverse a similar thing happens and another separate universe is created and so over and over the universe is created and the cycle repeats its self. This would mean that the "original universe" is even older than 14 billion years and was created by its self, spontaneously. The matter and energy came into being and built up over time and exploded. This would mean that there was nothingness, just empty dark space and some how mater and energy formed or it always existed, some how.
