Just a curiosity

It's been here for longer than that. Somewhere around 4.5 billion years if I remember correctly. But what about at a trillion years? It could be possible for us to move the earth eventually, though. We could possibly also halt the death of stars with enough understanding and skills.

Oh Boy....Your religeous views don't coincide with my scientific views. Please don't rag on me if you think differently.Read this... Stellar Evolution Then when it becomes a Giant Red :The Sun as a red giantThe Sun is expected to become a red giant approximately 5 billion years from now.[7] It is calculated that the Sun will become sufficiently large to engulf the current orbits of the solar system's inner planets, up to Earth,[11][12][13] and its radius will expand to a minimum of 200 times its current value.[14] The Sun will lose a significant fraction of its mass in the process of becoming a red giant, and there is a chance that Mars and all the outer planets will escape as their resulting orbits will widen. [15] Mercury and most likely Venus will have been swallowed by sun's outer layer at this time. Earth's fate is less clear. Earth could technically achieve a widening of its orbit and could potentially maintain a sufficiently high angular velocity to keep it from becoming engulfed. In order to do so, its orbit needs to increase to between 1.3 AU (190,000,000 km) and 1.7 AU (250,000,000 km). [16] However the results of studies announced in 2008 show that due to tidal interaction between sun and Earth, Earth would actually fall back into a lower orbit, and get engulfed and incorporated inside the sun before the sun reaches its largest size, despite the sun losing about 38% of its mass. [17] Before this happens, Earth's biosphere will have long been destroyed by the Sun's steady increase in brightness as its hydrogen supply dwindles and its core contracts, even before the transition to a Red Giant. After just over 1 billion years, the extra solar energy input will cause Earth's oceans to evaporate and the hydrogen from the water to be lost permanently to space, with total loss of water by 3 billion years.[18] Earth's atmosphere and lithosphere will become like that of Venus. Over another billion years, most of the atmosphere will get lost in space as well;[15], ultimately leaving Earth as a desiccated, dead planet with a surface of molten rock.[19]If you want to tell me that this will never happen then we have nothing else to discuss. We could possibly also halt the death of stars with enough understanding and skills. One can dream.

Our earth is not gonna be here....like forever....earth will be destroyed after some hundred million years.What happens to us humans? Well thats why research is going on to find habitable planets....humans may get settled on a far distant planet if humans are still exsisting!! that is.At the rate of pollution (air, water and noise), reducing number of trees in the forests around the world, increasing population, global warming, depletion of ozone layers, extinction of many flora and fauna, use of technology that is producing harmful radiation...........if you ask me I will only say humans are destroying the planet and bringing the end closer to us than nature would have intended it to be So forget about the earth being destroyed by our star--the sun and worry more of what to do to save the planet or heal its wounds that we humans have caused.

I dont think moving the planet is a good idea....if earth loses its axis the magnetic field--the planet would be in chaos and ripping earth of its revolutionary path will cause a lot of problems as well.You cannot halt the death of stars..........every thing has an ending point.........trying to keep them longer is just gonna make things worse.

Please don't rag on me if you think differently.Why must you attribute his difference of opinion to "religious views"? I suppose the reason his fav color isn't pink is because of his religious views too...yes?Religion doesn't cover this topic, and I think his opinion comes more from the positive exuberance of youth than anything else. He hasn't been around long enough to get jaded, like us.

No...moving the planet won't work. It's in a fairly delicate state of balance. Move it and it's all over for a lot of reasons. For the human race to exist into the future we're talking about, we'd need to find a different planet. Thing is our sun is one of the longest living and most stable kind of stars around...we'd have to find a third generation star just like it, which may not be easy since the third generation has not yet really begun and we won't know where to look for those stars until the time for the end of ours comes close.

Why must you attribute his difference of opinion to "religious views"? Because I know his past stances and posts on issues similar to this. I can read between the lines. Can't you? Anyways I would much rather someone post their own views rather than make me look like a bad guy.Awwww crap now we're gonners... Black hole confirmed in Milky Way

My views on this have nothing to do with my views on religion. Does that surprise you???

No it doesn't and your comments are rather short and ambiguous so I really have no opinion in regards to your views.

yep.......I know that very well. Shouldnt you have replied to the other poster--who posted the ideas first intead of me? Finding a different habitable planet is only way out if we still exsist for few hundred more years........our exsistence is already in danger as a result of what we are doing.....ruining our only habitat

_if we still exsist for few hundred more years _

Now THAT is pessimistic. I think we'll be around for longer than that. I would hope at least.

Look at the things around us and tell me if I am wrong.......pollution, deforestation, global warming etc etc. If we go on doing this then our chances are low :frowning: If we try to fix things ASAP then we could be here longer--our chances go up.

We need to stop polluting our planet. We need an environment to live-to feed-to breed. Humans can make/create any number of artificial habitats but instead of going through all that trouble--why not save our precious planet first?

I am not pessimistic just telling the facts :grin:

I think some fucker is gonna blow us all up with an atomic bomb.. or some shit like that!!

The earths magnetic field is basic (but not simple) physics. Scientists already have a pretty good idea how it works and are capable of reproducing it on a smaller scale. They are currently testing systems that use a protective magnetic field like the earth's to shield future long range spacecraft.As for whether humans will survive in the future, who knows? There are lots of possibilities including Steph's mad bomber scenario. But if our species does survive for another few thousand years, or goes on to millions of years, what you will find will probably not be what you'd call humans. And they might not call themselves humans either, through a combination of them evolving into something that would be defined as a different species and also that languages don't tend to last very long, so whatever word they use probably won't be "human".If the future is turns out in any way like it seems to be shaping out, our bodies are going to become more and more made of machines. We'll have genetically and technologically enhanced brains, limbs and organs. Our lifespans will multiply with people living to be up to a thousand years old, if not more. But none of it will happen fairly with the current form of government and society we live in. Destroy money, get rid of trade and the entire monetary system and run the world with a resource based economy and you can build schools and hospitals everywhere. Human resources would define the advancement of medical research rather than financial investment. Renewable energy sources could be developed without the hindrance of greedy fossil fuel companies. Transport systems could be developed so that "traffic jams" becomes a dead word, accidents wouldn't happen and you could go around the planet in just a few hours. The technology exists, it is being developed but it is going nowhere because it is restricted by a make-believe system of currency.

Utopia!!!

My point is that no one has the faintest clue of how far we will have advanced in the future. The advances in the next hundred years could be as far reaching as the advances of the past thousand years. With enough knowledge and energy resources, it is very possible that a highly advanced civilization could move the earth, although we'd probably be able to make our own places to live in space, so it would probably be to preserve the past. The same idea goes for the Sun. If we were able to figure out a way to manage the atomic content of the Sun, we could potentially keep it at the right amounts to keep it as it is or very close to it. Heck, we may even get to the point where we'd need to figure out how to survive a dying Universe.

Our planet will never die. Earth will always be here forever. Forever? You've said things in the past to the effect that "God won't let that happen". Thus my comment.If that's not the case, then I retract my statement. However, MY statements were not "negative" (although you want to cast that light on me) they were factual. What do your statements above mean? I'm curious.Positive thinking? Wishful thinking? Naïveté?

OK then.

My comments are usually very short online. Talk to me in person and you'll never get me to shutup!

I do believe we are on our way towards that future like you say....we are advancing at a good rate technologically and I dont deny that.I follow everything closely esp research going in the medical field and artificial intelligence/robotics.Call me an environmentalistic type if you like cos I am very much concerned about the other living things on our planet and our environment and the effect our use of technology has on them. Human race isnt the only one on this planet there are other plants and animals too. But I am all in for tech-advances that dont harm plants, animals and environment.
