1) The earth won't be a lonely planet, as it will get sucked in by the sun when she is expanding. 2) The proper English word would be "matter". 3) This is damn fricking interesting
<almost-a-pm> Yup ! Btw, the magazine I talked you about made a special issue about this type of questions regarding astronomy, physics and the universe. It's very interesting and easy to read. </almost-a-pm>
This When the Sun becomes a Red Giant in however many billions of years it will expand so much that it will eat the earth. Long before that happens though, as its hydrogen supply begins to run empty it will start to burn hotter and brighter, and all the oceans on earth will evaporate. Also on the matter of black holes, as i understand it they emit thermal radiation; that is to say heat, and thus they lose mass, but they do not emit matter (how could they, the gravity is so strong it absorbs light, but it just lets actual matter out?!). The amount of radiation they emit is inversely proportional to their mass; therefore smaller black holes emit more radiation, and therefore lose their mass quicker than larger black holes. Larger black holes absorb more mass just from cosmic background radiation, gas and interstellar dust than they lose through thermal radiation, and therefore can grow infinitely. Super-massive black holes (ye that's the actual term) which scientists believe form the centre of every galaxy in the universe - including our own milky way can only grow, absorbing stars and even other black holes.
Btw. in the middle of the milk-way there is a reallly huuuuge damn big black hole, and if you drive around it everythink is slower than everywhere else(time traveling). Also if that happens with the sun the humans maybe live on mars or something. I image a huuuge glas-(translator says me "astrodome", thats right?) <a class="postlink" href="http://www.morgenpost.de/multimedia/archive/00072/KuppelPur_DW_Berlin__72164b.jpg" onclick="window.open(this.href);return false;">http://www.morgenpost.de/multimedia/arc ... 72164b.jpg</a> In it are trees etc. that make oxygen and stuff and people live it it would that work?
Keep an eye on the discovery channel. There are lots of shows on it about space. Some are just a couple of years old and already proven wrong ! The mars rovers documentary was awesome to. They were supposed to run for what? 100 mars days? 1 was shut down after about 5 years. And if i'm not mistaken the other is still going strong!
Scientist arent sure about that, the sun would expand and become a red dwarf. The proces would definitely burn everything in here, but swallow is not clear. Venus and mercury are definitely gone, Mars would be the savest livable place to be, the orbit of Mars will expand when the sun turns into a red dwarf. But I would go hide behind Jupiter on one of the moons to be sure (Europe would be my first guess) The lifetime of our sun is in the middle (we have 5 billion years to go ), we have to much time to make Earth unlivable for us, we need to move in the distant future The easiest way to make Mars livable is making CO2, so we would have to give it an atmosphere by doing global warming :lol: Water on mars would melt and we can add bacteria and algae to produce oxygen. etc...
I'm pretty obsessed with space, I have a massive book on it (my only book). Just the reason I never went into learning about it, is the fact that its on such a huge scale, we dont have the technology to properly understand it. One cool thing I read is that there is one planet which is the same as ours (same size) - however its core is water and the outter part of it is just ice. And every so many years, the telescopes pick up a really weird glimce of light. And its because there is a volcano on that planet that fires water out into space, and this volcano is like the size of France. So when the water gets into space it freezes, and causes the light to glimmer off it. Pretty interesting shizzle. We are just a blink in the life time of space... and know nothing about it. Thats what interets me

Thats cool but its not cool that I dont understand everything. Sometimes I'd wish that Ive been born in like 4500 and we know ALOT of that stuff .
I'd say some dude in 1500 would have thought the same thing about 2011, and some dude in 4500 would think the same about 7000
Just you and me eating a pizza @ a science place, fall over and get frozen untill 4500...oh wait I know this [youtube]http://www.youtube.com/watch?v=QqzbZVDF3rs[/youtube]
I totally agree, it would not surprise me if World War 3 or some sort of an apocalypse whether man-made or natural happened within my lifetime. Ever heard of that beautiful Yellowstone National park in America? It is actually a sleeping super volcano and could well erupt within our lifetime: I watched the program that this webpage details (Its a fairly lengthy read but quite interesting, and you can go doom mongering to all your friends). I've picked out some of the "highlights" <a class="postlink" href="http://www.rense.com/general63/yellowstonesslumbering.htm" onclick="window.open(this.href);return false;">http://www.rense.com/general63/yellowst ... bering.htm</a> So we are about 40,000 years overdue... Also a little something from the dailymail: <a class="postlink" href="http://www.dailymail.co.uk/sciencetech/article-1350123/Worlds-largest-volcano-Yellowstone-National-Park-wipe-thirds-US.html" onclick="window.open(this.href);return false;">http://www.dailymail.co.uk/sciencetech/ ... ds-US.html</a> If you consider the fact that just 1cm of volcanic ash is enough to destroy agriculture, and where the hell would 2/3s of the American population go? Quite off-topic but relevant to what we are discussing. Whats going to happen when fuel runs out? Whats going to happen when we run out of these: <a class="postlink" href="http://www.cracked.com/article_19048_6-important-things-you-didnt-know-were-running-out-of_p2.html" onclick="window.open(this.href);return false;">http://www.cracked.com/article_19048_6- ... of_p2.html</a> Namely 6 and 2 but you get the idea. You can spend all your life worrying about what ifs and whens but i suppose you just have to get on with it and make it all count.
