NASA to Reveal Hubble Discovery of Milky Way's Violent Fate Thursday - Polidicks

[QUOTE=ZestyLemons;36143525]I thought the sun was going to expand into a red giant and swallow Mercury, Venus, Earth, and Mars in about five to ten million years, not billion?[/QUOTE] Billion.

I am hopeful that in a few billion years we will have reached other galaxies if we didn't kill ourselves on the path to it.

[QUOTE=sltungle;36140122]Life on Earth will probably be lucky to last another billion years at most anyway. CO2 levels have declined rapidly since plant life began dominating this planet. There's simply far more trees spewing out oxygen than there is anything else spewing out CO2. Eventually the levels in the atmosphere will be so low that in, I think it's estimated somewhere between 500 million, and a billion years from now, all plant life will die. Once it goes, all animal life goes too. And not too long after that point solar output will be high enough that even if we do keep everything alive and manipulate the levels of CO2/O2 in the atmosphere everything'll die anyway from the extreme heat, or lack of water.[/QUOTE] Why would that make all plant life die, it should just reduce the population until the CO2 output/input is balanced again

[QUOTE=LarparNar;36139802]Try reading the article again: Even from the article that [I]you[/I] quoted:[/QUOTE] Sorry but I don't see the irony here. NASA and the Wiki are pretty much 1:1.

[QUOTE=Jurikuer;36145495]Sorry but I don't see the irony here. NASA and the Wiki are pretty much 1:1.[/QUOTE] There's no irony? The point is that NASA will publish something new, but you seemed to imply that Wikipedia beat them to it, even before we know what NASA will publish.

It's not really our problem its whoever comes after us's problem

Would be wacky if Humanity developed technology to transit massive bodies between systems and use it to haul the Earth around as the heart of our civilization, using exotic technologies to maintain the traditional day/night cycles and life on it.

[QUOTE=Amaurus;36139120]By the time this happens, we will either be off this planet, or we killed ourselves in the process. (or we just killed each other in some war)[/QUOTE] Whats being off the planet gotta do with two galaxy's colliding? Were gonna need more lightspeed engines since we won't just be colonizing planets in the milky way.

We basically have infinite time to get the research to expand to other planets. It's the resources on our planet that will constrain us.

[QUOTE=Super Saiyan Yerbs;36140551]If in not mistaken, we are going to eat 2 micro galaxys before we hit Andromeda.[/QUOTE] Milky Way is muscling up before the prize fight.

[QUOTE=mac338;36141043]Some facts about this: Because there's so much space, the odds of any two objects such as stars hitting each other when the galaxies collide is minimal. I'm talking 5-1% - I don't remember specifically. So the odds of anything colliding with the solar system is especially small. The gravity from this new body will fling stars everywhere. The galaxies will eventually merge into a bigger galaxy after millions of stars have been flung into deep space. And even if that happens to the sun, it won't affect us. We're strongly enough attached to the sun by its pull we'd follow along barely affected. We might get a new view at night, but that would be the extent. This would also be a very slow process. The collision takes place over either 1 to 2 billion years. Either way, it is no cause for alarm. Much more likely is that we're all dead before that anyway. That is the hardest thing to predict.[/QUOTE] I seriously kind of doubt the human race could exist for billions of years. That is an extreme achievement of preservation.
