What came before the Big Bang?
Surely our concept of time is based on the daily rotation of the Earth? Does Time actually exist outside our own measurement of the Earth's annual journey around the Sun?
Remember Nathan, that the 'Big Bang' is a theory and no one has ever seen a 'Black Hole'. The way the whole theory is treated by the media and promoted by those theorists who research the 'Big Bang' flies completely in the face of Karl Popper's discipline on how a scientific theory should be tested. Can the 'Big Bang' theory be hypothesised and tested under laboratory conditions with quantifiable results?

Most accepted Big Bang Theory?
Another possible theory for the Big Bang happening is the ekypyrotic theory. Two branes in a higher dimension colliding, creating this universe.

Why is the Big Bang model favoured?
It fits with a lot of observation - particularly Hubble expansion and the microwave background. The Bondi, Hoyle et al Steady State theory made valiant attempts to stave off defeat but became more or less untenable after the microwave background data was produced.

Man-made nuclear bomb - one best evidence of Big Bang?
In many ways, the development of nuclear weapons, especially the H-bomb, did provide some of the best evidence for the big bang model. The theories of nuclear interactions and the technology developed to model those interactions lead the way for George Gamow and those developing his early work to model the nuclear reactions in the early universe. These theories lead to the use of the relative abundance of light elements in the universe as evidence for the big bang theory and they lead to the use of the background radiation, and its details, as evidence for the big bang theory. These have been two of the most convincing pieces of evidence in the cosmological community.

Would the collapsing of a universe provide enough energy for a Big Bang?
If my knowledge as an interested layman isnt outdated, i think most evidence at hand do not support a future collapse of the universe. Instead it seems like its going to keep on expanding as far in to the future as can be calculated.
If on the other hand the universe would collapse, would the mass energy be enough for a new round? Im fairly certain that science have no idea at the moment. If observations would have shown a decreasing expansion instead of an accelerating one, i think it would be a reasonable hypothesis though.
