For anyone curious, my Googling says that the trillionth digit of π is 2

These videos should really tie into the argumrnt in some way, "logical possibility" is the lowest bar and practically a grammar check for any argument.

This video feels like it needs a complete list of what the laws of logic are.
Like law of non contradiction, and law of identity, ect.
Speaking of which I think your last example violates the law of identity. So “existence=green” is NOT logically possible.

Is it really "generally agreed" that mathematical falsehoods are logically impossible? After all given the definition of logical impossibility in this video, this would mean that all the laws of mathematics are analytic, which is highly questionable. At least, all the attempts I've seen to reduce math to analytic statements rely on certain biconditionals/definitions which may not actually be semantically equivalent to each other (I mean that a good case can be made to the contrary).

So it's logically possible, that God doesn't exist, since a non-existing God doesn't contradict or violate any laws of logic.

Are you sure it's generally agreed that mathematical facts are logically necessary? For something to be logically necessary its denial would have to entail a contradiction, as you say... but if mathematics is synthetic (as many think it is), then I don't see how denying 2+2=4 would entail a contradiction

0=17.7777...

P1. 0 Celsius + 0 Celsius = 0 Celsius.
P2. 0 Celsius = 32 Fahrenheit
P3. 32 Fahrenheit + 32 Fahrenheit = 64 Fahrenheit
P4. 64 Fahrenheit = 17.777...Celsius

So, 0 Celsius + 0 Celsius = 32 Fahrenheit + 32 Fahrenheit

So, 0 Celsius = 17.777 Celsius

So 0 = 17.777...
