It's not really that much different from proving what happened yesterday, a century ago, 10000 years ago, and so on. You just have to work out what clues to look for.fassyman wrote:yeah you say that but there can never be proof of what happened all thoses billions of years ago can there...weedlefruit wrote:particle-jim wrote:people who don't understand the difference between a theory and a hypothesisweedlefruit wrote:For those who are questioning the Big Bang Theory, it is a theory that has been peer reviewed, tested and not-disproved for close to 100 years.

Yeah, too many people assume a theory is what people think rather than what has been tried, tested, peer reviewed and faced much criticism on a personal and local level, before seeing global review and being accepted as the way it is until a new, demonstrable concept is put through the same scrutiny. Takes years, decades for something to be a recognised theory.
It's not quite the same as when people say "In theory, this sofa should fit through to whole", although when it comes to religious arguments, it seems to be the argument for God(s) that relies on this misunderstanding.
your gonna dissagree but idk.

If you change some of the parameters used in various models for the beginning of the universe slightly, the universe would be very different from what we currently see around us. As it is, the inflation model for the big bang actually predicted a result that no one had ever seen before. This was then corroborated a number of years later. Therefore, in this case, reality confirmed the prediction.
Exactly yeah, we know how things were because of how things are now. Theories come unstuck of predictions are made which don't come to fruition.
When newton invented calculus to find out how planets move in eliptical orbit and don't fly off with their momentum, predictions had to made which at first had people laughing, until those predictions were realised.
