An interesting tidbit courtesy of Wikipedia:
The late Eugene Shoemaker of the U.S. Geological Survey came up with an estimate of the rate of Earth impacts, and suggested that an event about the size of the nuclear weapon that destroyed Hiroshima occurs about once a year. Such events would seem to be spectacularly obvious, but they generally go unnoticed for a number of reasons: the majority of the Earth's surface is covered by water; a good portion of the land surface is uninhabited; and the explosions generally occur at relatively high altitude, resulting in a huge flash and thunderclap but no real damage.
Someday we are likely to have something real hard bumping our noggin' though.

Hi Candadar, This was a great fckin blog man. I love this kind of shit and i can tell you have put alot of time into this. Im curious what you think about the big bang theory? Do you believe thas was how it started, I have heard alot of people who have other idea's.
Look. Matter and Information can not be destroyed, we know this. We may not know everything, but we do know one thing -- that there was an explosion. Big Bang is a more colloquial term for a scientific idea, and is very simplified at that. It just means that there was, at some point, a very large explosion. Since we know, as I talked about in the OP, that Stars are what produce elements -- that everything at one point was very basic. I know I'm probably going a bit off track, but a lot of people are uneasy about the Big Bang because they think that when it went boom, all of our complex materials came out of it which is simply untrue. Lots of dust, lots of hydrogen came out. Over time it collected, formed Stars, and those Stars became massive furnaces that produced new elements as they lived and died.
So yes, I believe a bang was involved. Whether it's parallel universe's that collide every few trillion years like in M-theory (and that's grossly simplifying it), or if it's a cyclic universe where it expands, contracts, condenses, and blows up again, we don't know. If I had to pinpoint a "belief" in something, it would be cyclic though. In fact, I would probably put the most trust in thinking the Universe works much like a collapsing star does. It is expanding at a rapid rate, and then suddenly it just collapses on itself at an extraordinary speed. After condensing itself at a superdense level, it gets super hot and explodes again -- hence the Big Bang.
Now that's most likely wrong, and there's a reason I don't take sides on this matter. Because we simply don't know, and I'd be a hypocrite to take a side. I trust in what we know, and that there was a bang. Everything else is speculation and math, and until we get something definitive, I leave the rest up in the air. I'm more concerned about what happened after the Bang, not before. Because trying to quantify what happened before the Big Bang would be like trying to ask what came before god. It's simply not a fair question.

Dude I want to read your rant on black holes now.

Man I don't. Every time I try to explain that shit I end up confusing myself and end up with 10 paragraphs of jibberish.
;_;
It's hard to accurately explain them without sounding like a looney too.

we are all born scientists, it is only society which crushes this desire in all of us to learn, to discover about the universe around us ~michio kaku
i agree, science is everything around us, we are all scientists in one way or another. and that is amazing

This looked like a good blog, then I saw you describe things like, "they're just super dense objects that fuck everything up" and "These fuckers are made from stars..." and I became immediately disinterested. Try to actually learn what you're talking about and you won't have to resort to saying things like "that fuck everything up" and you can actually explain what it does.

Are you trying to imply Neutron Stars aren't made in the aftermath of stars?
http://imagine.gsfc.nasa.gov/docs/science/know_l1/pulsars.html
Neutron stars are one of the possible ends for a star. They result from massive stars which have mass greater than 4 to 8 times that of our Sun. After these stars have finished burning their nuclear fuel, they undergo a supernova explosion. This explosion blows off the outer layers of a star into a beautiful supernova remnant. The central region of the star collapses under gravity. It collapses so much that protons and electrons combine to form neutrons. Hence the name "neutron star".
I was also grossly oversimplifying black holes, I thought that would be apparent by me condensing them (heh, pun unintented) into a 4 sentence paragraph. I intend to go into the meat of them later, and was just glossing over them for the sake of time. Black Holes are infinitely dense singularities that fuck everything up, that's the bar none, simplest way to put it. Or are you implying that me using the word "Fuck" so liberally somehow discredits my point?

I loved it, please do one for black holes, also what do you think of aliens? i know its a bit far from what you are talking here but still :3

I think that we are looking in just a very small corner of our galaxy and we have found dozens of planets that are Terra, or could potentially support some form of life (although most are less likely than some). I think that there are billions of stars in our galaxy, and there are hundreds of billions of galaxies with trillions of stars in them -- most with their own planetary systems. I think that Natural Selection is a very amazing thing and that life is present in very extreme areas on our planet, and I find it really stupid for someone to say that there is no chance for life out there.
I will doubt that there is a hyperintelligent race out there that is going to come kill us or something, or some galactic empire or a Type 3 Civilization or something out there. However, I would not doubt for a moment that there are dozens if not hundreds of planets in our own galaxy that harbor some form of life.
