Its logical to run away from something that will obliterate everything.

If there is a species semi-like humans alive in 5 million years (the sun is supposed to go crap in 5 billion) I'll eat my hat.
I agree with you. I think that in the future, then people stop to think a bitStrategia wrote:AF means helium-3, not hydrogen-3.P3374H wrote:IIRC it's made fairly cheaply in a nuclear research facility in Ontario, and exists in the upper atmosphere also.

Right now? Yeah, you're right. However, when the infrastructure is in place, we can use space travel for economic reasons; like Zoombie, AF and myself said, the Earth's resources are finite - but we can extend our supply a heck of a lot by exploiting various types of space rocks.neddiedrow wrote:Space travel is an economic sinkhole. There is no way to travel into space and return with a profit in any sense - every time we dabble in it we simply reduce our own resources. This is not negotiable, it is scientific fact.
Besides, who says we need to "return"? Once the orbital facilities are up (not if, but WHEN), we don't ever have to return to Earth in anything except specially-built passenger and cargo shuttles. We can leave the interplanetary and (possibly) interstellar travel to ships built entirely in space, thereby cutting the fuel requirements immensely as they don't need to climb out of as deep a gravity well as the shuttles of Canaveral. Plus, once fusion drives are developed to be sufficiantly economically viable, fuel costs will go down into the cellar, since about 75%(!) of the universe's matter consists of hydrogen.
Moreover, we can eliminate pesky problems like pollution (well, the source of the problem - not the effects), overpopulation, power production et cetera by dumping our waste into the furnace of Sol, building offworld colonies and/or space-based habitats and building solar satellites in close orbit around the Sun. All that may not be economically viable (at least at this time), and may never turn a profit EVER, but it can help alleviate problems we have to suffer from if we stay here, confined to this one planet. Economy isn't everything, and not everything we do has to turn a profit.
If all we do has to turn a profit, and the maximum profit at that, we will ruin ourselves within a century - within a decade, perhaps. We are by nature a social species; therefore, we must act socially. We must base our judgments and decisions not only on what is best for ourselves, but by what is best for ourselves and the group - the rest of mankind, if you will. By extension, all space travel need not be intended solely for personal or corporate profit; if we can alleviate problems by utilizing space travel at an economic loss, then we must.

It's unclear what will happen as the moon's orbit destabilizes - it is quite possible it will either crash into us, or slowly break apart giving earth a saturn-like set of rings.Quanto042 wrote:Somewhere between 250 Million - 1 Billion Years, The Moons orbit decays to the point that it slings itself away from the earth, causing the earth's axis to wobble uncontrolably..
There's also the fact that some people in NASA (the bureaucrats) are a bunch of money grubbing bastards. They have a LOT to gain by making everything they do as expensive as possible because that means more money in their pockets.neddiedrow wrote:Space travel is an economic sinkhole.

For some reason I think you got those a little mixed up. THe Milky Way and the Andromeda Galaxy's are still nice and far away, right?Quanto042 wrote: Here's the timeline of earth ending events:
