Is it just me or is this subject an ad-hoc mess which fails to arrive at satisfying conclusions? Also, what is an effective way to compartmentalize the techniques and results?

just stand up and explain that you need to poop again because you have diarrhea.

Then you can probably get away with going back in there a third time to jack off again

How likely or unlikely is it that there is life within our very solar system?

See, most of the things that make Earth unique come from space dust (formed in stars which then die and spread over the Universe). Also some of them come from meteors. So if lots of space dust and meteors fell on Earth, just how small is the possibility that this isn't true for other planets like Mars or moons like Io and Europa? And if these chemicals that are the stuff of life are all over our solar system, why is it not more widely accepted life is actually very probable to exist in our solar system? Before you say "but muh gas planets", keep in mind those planets are orbited by hundreds of rocky moons.

Very.

Not sure if this is the right place for this, but does anybody have anything to say on the pole shift?

Apparently this genius thinks Atlantis is going to pop up off the east coast.

I've seen some graphs showing the northern pole travelling towards Russia and the southern one having cleared Antarctica. Is any of this true?

The Earth's magnetic pole DOES sometimes "flip", but the last time this happened there were no humans on Earth, and it's JUST the magnetic pole that flips, not the physical pole, ie, the Earth itself doesn't move and in fact if you didn't have a magnetic compass to check you wouldn't even know it had happened.

So I'm trying to figure out this issue with lenses.

I want to place a single lens, or small, simple stack of lenses a short distance from a flat surface with a word written on it, such that the word is out of focus when an observer looks through the lens. Then, by moving the lens closer to the surface, the word comes into focus.

One: Is this possible for an observer at any distance from the rear of the lens?

Two: How would this be achieved, either for an observer at any distance or at a distance of, say, 1 meter?

The sats are in geostationary orbit. Plus there is a repeater network

>How about an unstoppable mouse? Now most mice can be stopped! You can put a wall in front of them and they can't go through the wall! You can put them in a box! You can stop them! Okay, so we have the notion of a stoppable mouse. Does that we therefore have a notion of an unstoppable mouse? Is that a sort of a necessary flipside to the concept?
How can one man be so based? He has BTFO the entire modern mathematical establishment, but how do we make this more well known? Most people are still unaware of the illogical foundations of modern axiomatics, and in particular the establishment mathematicians are unwilling to adopt the Wildbergian framework.

I understand how one species scattered in different environments might lead to different but similar species, but how do we know it works the other way around? Couldn't tons of variations of the same animal just magically poof into existence, instead of coming from a common ancestor?

Is this a spanish text? Maybe the notation is different, but i would guess that the equation is describing acceleration as velocity over time, so I'm guessing that symbol is supposed to mean some kind of = with a derivative.
