How would you know?

[Napoléon]

I believe there is evidence to support it. Would you like me to quote a biblical passage I have in mind, or would I just be wasting your time?

Unless it specifically mentions a place called purgatory by name, describes it, tells us why people go there etc. then yeah, you're probably wasting your time.

If it's as vague as most other bible verses I get quoted with then I'm not interested at all.

The difference between Einstein's theory of relativity and theories about god though?

Oh yeah, that little thing known as scientific evidence.

But not at first, Napoleon. His theory of general relativity was just something he imagined, which was supported only by his mathematical equations. The evidence of scientific experimentation done by others came years later. The same is true of string theory. Most physicists agree there is no evidence of scientific experimentation to support it.

Are you trying to be this dumb? (see bolded to recognise how Einstein's theories differ from religious theory)

Einstein had his theories accepted because they made sense, could be proven mathematically and indeed, like you said had experiments confirm it perhaps years later.

But to compare this with any religious theory, which has no solid mathematical principles, other than magic, no evidence, other than some ancient old tomes, and has been trying to explain things (unsuccessfully) for thousands of years but still hasn't succeeded as far as science is concerned, is totally out of whack.

And as for imagination? Einstein didn't just wake up one morning and magically come up with his theories off the top of his head. He came up with them to try and solve specific mathematical, and physics based problems.

Again, this is in no way similar to the mindless imagination of religious theories. Einstein using his imagination to come up with his theories, at least had some grounding in reality. Unlike religion, which is made up out of thin air.
