The future in understanding our past is like good wiskey. Slowly little sipps of New knowledge will make the hole picture come together like a jigzaw puzzle we will get there with time. Fasinating !!!

It could be debated that we descended from fish: Your Inner Fish Episodes | You Tube The precedence would be: Fish >Amphibians >Reptiles >Mammals

Yes Anak I think that is very possible. In England the BBC has made some really good programs with professor Brian Cox. They are called " the wonders of the universe " and so on and are really to get more people interested in things that are considered "too difficult".
The program " wonders of live " is about the questions around the evolution and what we know for sure nowadays. I find all these documentaries really worth watching.

From the; "Can they get any bigger department?" You betcha!

A dramatic new image from the Hubble Space Telescope may offer fresh insight into one of the great mysteries of the universe: black holes.
The image shows a bright white orb against a starry black background. Located in the Coma Cluster, about 300 million light years away from Earth, the orb is actually a distant view of the giant elliptical galaxy NGC 4889. At the center of that galaxy lies a sleeping giant: a supermassive black hole that is 21 billion times the mass of our sun.

21 billion times?!? Now try and wrap your head around that! I'm probably way off but can't a million Earths fit inside the Sun?

Right there in the center folks!

Ditto that Thelma have all his stuff and he puts ii all in a non jargonstic manner.

Isn't it so that in space there is no direction, there is no up or down, left or right, backwards or forwards?

Doesn't that mean that we have no idea in what direction we are spinning around the sun?

 

[z3r010]

Absolutely!!! our perception is only that of what we have observed in the tiny time we have been here.

 

[kado897]

Everything is relative to the observer.

 

[z3r010]

Absolutely, and we are so tiny in the observable universe that we are completely irrelevant in the grand scheme of things.

 

[BorisTheAnimal]

Absolutely!!! our perception is only that of what we have observed in the tiny time we have been here.

I think it's freaky to think about it, maybe this has something to do with my weird feelings.

 

[kado897]

If you think about it Boris there are two different situations.

1. Up and Down are properties of a gravity well so on earth there is an up and down. Its direction is independent of the orientation of the observer. There is also a different up and down on the moon but there is no up and down where there is no gravity.

2. Right, left, forwards and backwards are different. They are properties of the individual. I have a right, left forwards and backwards which I take with me wherever and in whatever orientation I am. It is different to your left, right, forward and backward and everyone else's however.

 

[BorisTheAnimal]

But if I were at the North pole and you at the South, wouldn't my up be your down and vice versa?

 

[kado897]

Up and down are properties of the gravity well. Up is away from the centre of the gravity well down is towards the centre of it. This is independent of the observer.

Boris:

If a bear walks south for one kilometer, then it walks west for one kilometer, then it walks north for one kilometer and ends up at the same point from which it started. What color was the bear?

White, although I don't think they go that far north.

 

[Anak]

You are correct on the color; As for location usually no, but there was one that crossed from Alaska to Greenland across the north pole region.
