You DID read the forum name when you entered, right?Strategia wrote:Can people please stop posting nonsense here? Please?
This isn't a politics forum, nor a scientific debate forum. its the post random and useless stuff forum.
Besides, at least they are moderately on topic. All of the spam so far HAS connected to the topic. Galatic Gate - OTA's answer to space travel. Overlords - Zerg mind thingys and somewhat air transports...
Just because you can't see the humour of it doesn't mean we can't.
If we colonize for example mars and the earth goes boom because of nueks we still have marstombom wrote:Haha.RaiFox wrote:Well isn't the sun going to explode eventually?
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.
, they will live in some sort of comunism and so only the amount of material (not monetary) resources wasted will be considered and if we consider only that I think space exploration becomes profitable. And who knows wich infinitly advanced tech will be invented in future? We dont consider that we can advance much more than we already advanced because we cant imagine something much more advanced than our tech, but our antecestors also couldnt imagine computers would exist someday 
. I believe in the future there will exist much faster ways of travel that will take us to distant star systems in a blink...
Here's the timeline of earth ending events:Strategia wrote:The Sun will go boom in five billion years, give or take a few million or so. :)
5 Billion Years, Sun explands and swallows the earth.
3 Billion Years, Milky Way Galaxy Collides with Andromeda Galaxy
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, the tides disappear, and the world climate gets royally fucked as a whole.
The Purpose of space travel? Get the far far away from the earth and this galaxy before any of that happens :D

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..

I heard that its orbit is falling by 4 cm every year...
But meh, The reason we need to go into space is becuase if we don't go into space, the Drenign will bumrush us with defender mk 1's and a few transports, and we'll be helpless, HELPLESS I SAY.
Thats a Galciv 2 Referance. if you haven't play Galciv2, you are made of fail.

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.

If you want a really good book on the hows, whys, and how-much it will take to get to and exploit Mars, get a book called: The Case for Mars by Robert Zubrin. It shows how to get to Mars without a massive infrastructure, without 'battlestar galactica' style massive spaceships and without trillions of dollars.
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:

Also the collision would only be noticed when another solar system gets into our gravitatinal range and the Earth plummets into the sun or something...
