I would disagree with that on a few different levels, but specifically in regards to where over half of all governmental spending goes.
Just one point I don't want misrepresented is defense and science are very small portions of the overall budget, but I was referring to discretionary spending relationships when I said over half of all governmental spending. But even in terms of the whole budget military spending is usually around 15% and science and education get 1-2% each respectively.
To bring this around...
Amazing picture.

I think we should send Matt Damon.
If it were up to me, and the world wasn't full of self-centered idiots, all the military funding and a bunch of other wasted money would go into science and education. So to me, Mars and space exploration are a means within themselves.
Huh. I legit thought you were going to say we'd cure world hunger or something.0 -

Science already has the capability to this and has for years (seed, soil, drought tolerance and pest resistance biotech) but there isn't funding to put transportation and implementation for countries that need it. So again, well funded science would solve MANY world problems.
I will mention, I am not fully on board with genetic mutation or "enhancement" for anything.
And because space...
Updated Mars pic. Great resolution.

I believe ours is a black hole

I think it's dormant or at least it was. A dormant one can't be to bad eh?
Well, yeah unless someone throws some fertilizer on it and works the roots then it could come back strong.0 -
Can someone give me a lay-gist as to what makes a black hole become dormant and what might make it become active again, if that is something that happens.0

Maybe God installed a clapper.

A few years ago, I read a Carl Sagan book, it was basically telling the story of history from the big bang until modern times. It was a great read.
Sagan wrote that the oceans fell out of the skies. He was referring to icy meteors, which, over the eons, might have accumulated enough water to fill our greatest basins.
Last night I was reading about how this isn't what we think anymore, the Earth was formed with much of its water already here.
I always go back to a episode of Friends when Ross was belittling Phobe for believing in a different theory about evolution, etc. His agrugment was how could she argue against science?. Her response? "Ross, at one time didn't the brightest scientists believe the earth was flat? So you're telling me there is no way current day scientists could be wrong with their theories?"
End of discussion.
Friends - it's where you learn about science and stuff
Cool story, bro.0 -

I just wanna experience it from the ground. On the bucket list.0 -
I've seen them from Slate Peak, at 48 N. In the photos they're green and red, but in real life they looked like a very faint gray cloud over the horizon. Modern cameras are much more sensitive than our eyes.
So, go further north to see them. Or south.
I guess your best bet is in winter because of the longer nights.0 -
Is the Aurora from space the Aurora Borealis or the Aurora Australis? Or are there other kinds of Auroras that aren't at the poles?0

I live in southern Ontario, I have seen the Aurora Borealis in the summer while camping.
The first time it was a bit freaky 'cause I didn't realize what I was seeing.1 -
Is the Aurora from space the Aurora Borealis or the Aurora Australis? Or are there other kinds of Auroras that aren't at the poles?
I'm going to assume Borealis, because of the cities on the ground. Could be wrong, but I think there are a lot more people living closer to the north than south pole. Those lights could easily be Alaska, Scandinavia, or Russia. I don't know how often auroras would be visible over Australia or New Zealand; I'm guessing you'd have to go further south, and then you wouldn't see city lights. I could be wrong.
I think they only happen at polar regions, but not only on Earth.MeeseeksAndDestroy wrote: »

Halley' Comet
Appears every 75-76 years, it's last appearance was in 1986. The next chance to see it will be in 2061.

Saw it last time around (kinda!) - I guess there's a slight chance I'll get to see it again!
(I'd be about 95 though!) 0 -
Hard to imagine, but if you went to the beach and grabbed a handful of sand, each grain would signify a star in just our galaxy alone. Now imagine if you were told that the Universe's stars outnumber EVERY GRAIN OF SAND ON EARTH.
