An untestable hypothesis is not science. Science is ideas and hypothesis that have undergone the scientific method. Until then it’s just a thought experiment.
Yep. If it’s not testable, it’s not science.
I was watching some dumb video where a Christian “scientist” was trying to “prove” that god was the best scientific explanation because it could not be wrong. Which is exactly why explaining things with god isn’t science.
Depends on what you mean by “The Big bang”. If you’re talking about a seemingly spontaneous explosion of matter ~14 bya, then no, that’s not science. That’s like saying that the sun, or dirt, or a hurricane is science. Forming a hypothesis that all matter can be traced back to a single expansive event, then observing movement of celestial bodies, measuring those movements with redshift and seeing if that data is in-line with your hypothesis… That’s science.
