Ad astra!
Not at all...and I took a look at your wiki offering.
None the less....Einstein wrote his famous equation using light as a constant.
He then set that equation aside for several years, looking for a better expression.
He died knowing the work was not done.
And it may never be.
As for God...
You already know, from previous threads...
There will be no proving by equation, or experiment.
No photo, or fingerprint.
When it comes to believing in God....
you just have to think about it, and make up your mind.
As for logic....back to cause and effect....spirit first.
Spirit doesn't exist.
Back to square one for you.
As to the Einstein being on to something, if he was, we will find it given some more time. That's the nice thing about science, even if someone dies studying something it will still be there to uncover.
