space questions

[Damocles]

couple of questions for the braniacs here

1. If most living things were wiped out with the meteor hitting earth, what did Humans evolve from ? what was left that gave rise to us ?

2. i was walking the dog through the woods the other day and looking at all the rotting leaves on the ground, and thought would the earth keep getting bigger with all this vegetation over millions of years ? as it is new matter and not reused ?

The little rock pools filled with amino acids that heated up and were (as one theory suggests) catalyzed by lightning and we think we developed in this manor (that is a very basic example though). Comets and asteroids will have hit after the earth cooled and calmed again thus delivering the basic ingredients.
Small mammals also survived these ele's underground so we could equally have come from them.
Advanced life may have been stalled a few times in this manor.

This vegetation just rots and gets reabsorbed by the tree which will eventually get cut or burned etc etc.
It is just energy transforming from one form to another. The tree has potential energy in the form of heat for example if you burned it.
The oil we burn is just very old leaves and dead stuff again getting transformed. It is just a big cycle really bud using the same stuff.

its crazy though that dinosaurs took 100's of millions of years to evolve and humans around 7 million. Always intrigued by this stuff

Humans is a species though whereas "dinosaurs" covers almost half a billion years of evolution

still relatively quick from early ancestors to homo sapians in the grand scheme of things, Charlton Heston always looked good in the films

Depends on what you mean. As anybody who has tried to argue about evolution with one of the nutjob brigade will attest, there is no fixed point where we became humans so you sort of have to agree on a starting point.

Homo sapiens sapiens which is what we are today have been found up to about 200,000 years ago but the Homo genus with the divergence of us and Pan (chimps, etc) started around 7 million years ago.

We've only been colonising for about 50,000 years and only civilising for 4000 years. And we've visited the fucking Moon, how mint is that?

you're right it is truly remarkable what has been done in the last 2500 years and more so in the last 150 years, Learning to farm 12000 years ago to the bleeding iphone !!

Yeah quantum entanglement fucks my head up. This stuff even gave Einstein a headache.

I've never found this so mindblowing as other people.

Can never think of a good analogy for this which is why I skipped it earlier. I suppose the best one is if somebody whips a corner in and both Kompany and Yaya got to head the ball and it goes in for a goal. Nobody knows who scored the goal, all we know that the combined action of Yaya and Kompany jumping towards it resulted in a goal. Essentially the goal is in a superposition of states where both or none scored it depending on how you want to look at it. Then when we look at video replays, we can see that Kompany got the touch which means that Yaya must not have scored.

That analogy makes it even more confusing.

We're shit at corners.

Yeah it's crazy to think Dinosaurs might still be around if they didn't have that Jurassic World War after Tricerotops drew a funny picture of a T-Rex. Oh well they did have smaller brains didn't they

This that cat in the box bollocks, where it's neither dead or alive as nobody is observing it...wtf I'm pretty sure the cat knows if it's alive or dead. All that multiverse theory is a bit far fetched isn't it?, if it's true I'm glad I was in the universe were Gerrard slipped on his arse, as out there somewhere a universe is getting it's nut done in by dipper fans still parading their title win around it..but I have 12 inch cock and I'm a spiritual leader of a sex cult (women only) so it's not all bad

The cat is both alive and dead until you open the box. What many don't understand about Schrodinger's Cat is that the thought experiment is supposed to be ludicrous, it was his way of arguing that quantum mechanics and entanglement doesn't make any sense. He was right, it doesn't make any sense but this doesn't make it any less true.

Quantum entanglement gets such a bizarre reputation in pop-science that it is a frequent target for purveyors of woo. It's simpler than that.

Let's say that we have two objects that are floating around. One of them has the value "red" and the other one has the value "blue". They join together in perfect harmony to form the object "purple".

Now we know in "purple" that there are two objects but we couldn't say which one is "red" and which is "blue" without measuring them. Due to this, we use a term saying that both objects are in a superposition where they could be "blue" or "red". The objects do have a value, we just don't know what it is and use probability to describe them.

Once we attempt to measure the "purple" object, it breaks down into its component parts of "red" and a "blue" and the superposition is corrected.

All that multiverse theory is a bit far fetched isn't it?

Depends on which one, there are loads of multiverse theories that describe many different ideas. Some of them are shite but some have merit.

, if it's true I'm glad I was in the universe were Gerrard slipped on his arse, as out there somewhere a universe is getting it's nut done in by dipper fans still parading their title win around it..but I have 12 inch cock and I'm a spiritual leader of a sex cult (women only) so it's not all bad

If the multiverse hypothesis is true than there are Universes out there where you are the absolute ruler of the Earth and all men/women bow to you due to your massive dong.

All hail the dong xD

My head breaks at the beginning really. You break it down well but my little head can't deal with the underlying math.
You could explain it a hundred times to me i think bud and all you would receive is a puddle of drool from my vacant confused face. I guess it is stay that way or learn everything about physics and still then could only look at the language of said maths.
I just can't grasp the idea of a particle being able to instantaneously affect it's equal 5 billion light years away for example, This is where my cogs start to jam.

I want my cannabis universe damnit !
