It was a serious question...not about the appearance of the rainbow per se, but the shape it took.
And what I was able to follow of the videos you posted made some sense, although I just looked at snippets.
"The Magic of Reality: How we know what's really true
The above book contains a thorough explanation of all that you need to know about a rainbow.
The world won't end until God decides to end it.
Since you have no idea of the truth of what you're stating there, it's probably a safer bet and a less embarrassing statement if you would say that we know with great certainty that the sun, unknown to itself, has a surefire plan to end the material world in about 5 Billion years. That is of course, if some other natural cosmological event doesn't do it first.
I can imagine your disappointment with that knowledge though, as I'm sure that you and many others were really believing and looking forward to, with great anticipation, riding a war horse in the clouds and wielding a throatslitting sword in a messy bloodbath with king jesus as your fearless leader............
^^^You gotta wonder though about the method of battle, transport, and weapons ?
Jesus:"Here lets use these swords and horses at Armageddon !!"
Saint:"What!? jesus have you not seen modern weapons!? They're lethal and quite scary my Lord !!
Jesus:"Shut up !! It makes for a good traditional story, so get on your horse !!
The universe is amazing, but it is still a dangerous and violent place.....and you've allowed yourself to fall madly in love with an idea that adds its own dangers to us and therefore exacerbates that fact further for us here on earth......perfect--way to go
