Here's the part that I find interesting. The whole gravity/space-time curvature is merely an abstraction of gravity into a new dimension.
Ancient people's idea of gravity was simple. Stuff goes down.
Then people figured out that the earth's surface is curved, and "down" didn't work anymore. The new theory of gravity said that stuff moves toward other stuff, and the earth is a big blob of stuff that all our little stuff moves toward. Kinda simple, but you don't have the nice, straight, linear sort of system. You've got a radial one, and other planets and stars have their own gravity fields that pull stuff toward them, and it's a bit more complex.
So, with this notion of mass curving the surface of space/time in some higher dimension, we envision space/time as a sort of elastic surface. Mass sinks into the surface, and smaller mass will "roll" into the depression caused by the larger mass. Why does the "mass" roll downhill? Well, there's the kicker: this higher dimension apparently has its own sort of gravity, and, like the ancients' theory, it's nice and straight: it always goes down!
That's not actually true. Take a square apiece of paper. Draw a straight line parallel with one side in the middle. Then tear the paper perpendicular to the line from one side to the line. Now pull one side of the tear over the other. See how the paper bends into a cone? That's what gravity does. It causes "space" to not be flat just like that. However, look what happened to your line. Now it curves around toward the direction of your tear. So it is the geometry of the paper that causes the gravity. It isn't about anything rolling downhill, or about there being another type of gravity pulling everything down a rubber sheet. Instead, the shape of surface causes anything going in a straight line to be deflected towards that tear. And why does your object tend to go in a straight line? Because of Newton's first law, of course!
Read my post in context with the parent to which I was responding. Original poster used the term "fucking barbaric" to describe a country that executed drug users and I was suggesting they thought a little more about their posting.
Agreed my language should have been more carefully chosen. I completely agree the issue is more nuanced than a short response can provide however felt it would be mostly lost on the original poster, hence decided to give them a blunt response to get them thinking about what they'd written. Perhaps I shouldn't have jumped back at a troll...
Clearly you are more capable of a more rational debate and it would be more pleasant to have a decent conversation and discuss the issues with you rather than User Jaysyn.The issues are indeed complex.
I'd note though that the State of Texas- a part of the USA - apparently still reserves the right to execute under 18 year olds and President Obama has promised to review the failure to ratify the Convention (Ref.)

I think that it is very strange to defend a blunt response if it can easily be shown to be incorrect. For example, I could call you "fucking barbaric" for murdering children too, but that would be incorrect and certainly unjustified. At very least, your outburst makes you look very silly to me. The context doesn't compare the US to anyone, and the post doesn't imply the author is from the US at all. So your remark about the US is certainly off-topic and not supported by the context.
Your reference from wikipedia is probably incorrect. The citation in wikipedia for the remark, that Texas reserves the right to execute 17 year olds (Texas's previous limit), does not mention Texas at all! I did a search for texas in that article and got nothing, so (unless my browser is malfunctioning) that wikipedia statement seems baseless to me. So I will edit out that reference from the article.
Furthermore, Texas cannot overrule the US constitution, and the supreme court has already ruled on the matter. There was a case mentioned in the wikipedia article where they tried to overturn the ruling in Alabama, but that went nowhere (and rightfully so). So that reference that you cited can not support your argument in any case whether true or not.
Finally, Obama is a politician. He cares a lot about symbols, as shown by his public reasons for "firing" a CEO. I repeat that: he forced a person to retire from his job because Obama wanted to emphasize a point. Doesn't matter if it was justified for other reasons or not - that was the reason suggested by the man himself. Obama also recently suggested a world without nuclear weapons, though there are many reasons that is currently unrealistic. Obama declared it probably won't happen in his lifetime, in fact! So the point of mentioning that goal was also symbolic. The UN Convention is also a symbol. So Obama's support of ratifying the convention is not surprising, but also not a sign that he thinks it is realistic or even possible in the near future. Of course I could be wrong, but I think this is the likely conclusion.
Only two countries in the World refuse to sign up to the UN Convention on the Rights of the Child, and declare their right to execute children as part of their legal processes:
1. Somalia
2. United States of AmericaCareful who you are calling barbaric, some people might also call executing kids a pretty primitive practice.
If you are going to call the US barbaric, please use a correct reason. Just because we did not "sign up" (we did sign it in fact, just not ratify it) doesn't mean we don't support most of its ideals. The US Supreme Court ruled that it is unconstitutional to execute children as part of our legal processes. So the US is not executing kids, unlike what you are claiming.
Now there are many reasons why we should ratify it. There are also reasons why we might not be able to ratify it. For example, it could be unconstitutional. So it is not a clear issue and should be debated and considered with much thought. However, using loaded words like "barbaric" and "refuse" is unfair when the issue needs more discussion. So you please refrain from such derogatory and untrue characterizations.
On an up note, however: "Nato commanders in southern Afghanistan are deeply concerned at the level of corruptionCharles Heyman, a defence analyst and former British Army major, said millions of pounds earmarked for reconstruction were being siphoned off. "It almost comes with the programme," he said. "You have to build in an element of that into any programme because you know it will leak into people's pockets."
So here is a case of a state legislator, who blew a
It's a naive, domestic operating system without any breeding, but I think you'll be amused by its presumption.
