I read an interesting article in space.com today and I thought I just put some of my thoughts down on the subject before they drift away into oblivion..

Here’s excerpt from the article:

“A new calculation predicts that Earth will be swallowed up by the sun in 7.6 billion years, capping off a longstanding debate over whether the sun’s gravitational pull will have weakened enough for Earth to escape final destruction or not.
After a billion years or so you’ve got an Earth with no atmosphere, no water and a surface temperature of hundreds of degrees, way above the boiling point of water,” Smith told SPACE.com. “The Earth will become dry basically. It will become completely impossible for life of any kind to exist. It’s a pretty gloomy forecast.”

Some of you might say “start packing”, or start purchasing that “doomsday insurance policy”, but we have a long way to go, and I thought up a perfect solution on how to escape this really horrifying demise anyway, so put your suitcases away and listen up.

Easy three step solution to avoid earth’s destruction:

Current trend on how to avoid disaster of this magnitude is to simply pack our bags and colonize other planets or send city-sized spaceships filled with people into the space and have them drift away until they reach habitable planets. That’s all nice and dandy but why spend time, resources and probably lives colonizing other planets and building huge spaceships when we already have one. You’ve guessed it. Earth. The only thing we have to do is to move the Earth away from the Sun before sun gets big. That’s it. Or better, transform the actual earth into a spaceship itself. Let’s call it The Earth-Ship. Imagine the possibilities. If you thought that this would have some challenges you were right. Not only we have to escape expansion and horrid heat of our sun, but we would have to find a new one, since as soon as our Sun expands as far as its own gravitational core allows it, it will implode and probably become useless white dwarf, so I made following instruction in three easy steps just to prevent that from happening. So Astro-Physicists and Cosmologists pay attention.

1. Building custom atmosphere. We need to build our own atmosphere here on earth and be able to turn it on and off at will. And I’m not talking about just any natural atmosphere induced by algae growth (yawn…) or some other “slow” process that scientist are planning to implement on Mars. We need a complete protection, functionality and transparency from the outside space. Something like artificial sphere or a cocoon with its own weather system controlled completely by humans (or AI if advanced enough to be trusted). Not only this atmosphere will have to protect us from alien outside factors, but also from asteroid or comet impacts so it will have to be also very sturdy or very dense. We would have to be able to control everything from rain, sunshine, oxygen and magnetic fields to photosynthesis. If you all watched movie “The Truman Show” you will get the picture. If you haven’t, spoiler alert now! In the movie the whole city with some of the surrounding area is encapsulated into artificial bubble and everything from weather to sunlight is artificially produced and controlled by mad producer/director/creator Cristof (played by Ed Harris). We will have to build something like that but on a global or should I say “celestial” scale. It will also have to be very transparent so we would be able to get on with our lives uninterrupted. Considering that science progress is non-linear some scientist think we’re actually only 100-300 years away from developing technology like this. Let’s say we’re 1000 years away just to be safe.

2. Harnessing Sun’s energy. Next thing we need to figure out is how we’re going to live on our Earth-Ship without our Sun. Most of the life on earth depends on sun so let’s just all agree that we really need it. We could probably harness enough energy from our current Sun before we fly away into space. That would give us enough manipulative energy until we reach our first closest star. Now, our closest star Proxima Centauri is four light years away (4.2 actually), which would mean it would take us four years to reach it if we traveled at the speed of light, and with anti-matter rocket propulsion and solar sail some scientist really believe we can reach at least 10% of light speed. If you’re worried on how will human body endure 10% speed of light travel, don’t. It’s done by gradual acceleration and deceleration so humans won’t even feel the impact of speed. Moving on… So we need to conserve at least 40 years of Suns energy; probably double or triple that just to be sure. (Ironically one could say we already are doing this by uhmm “greenhouse effect”). Once we approach Proxima Centauri we would have to calculate exactly prefect distance from Earth-Ship to the star so we can stop the Earth-Ship at that point and start harnessing its energy. We don’t want to get to close, but just to be safe bring your sunscreen. When we get bored, we would then move to other stars or simply stay in certain orbit if it comfort allows. We would also need to become masters of not only converting mass into energy (burning a lump of coal for example) but also turning energy into mass (closest example for this is photosynthesis). Some scientists are saying that we’re tens of thousand of years away from achieving something like this. To be safe let’s just say we’re 100,000 years away. Just to put it into perspective: that’s ten times longer then our current recorded human history.

3. Navigate the seas of the stars. Final thing we need to figure out is how to propel the Earth and navigate it the way we wanted it, and thus escape sun’s gravitation pull and basically hurl ourselves away on our own galactic plane into the vastness of space. Closest analogy to something like this I can think of would be “Death Star” from Star Wars movie. There are many things we could do this with. One possibility is to use “solar sail” which is exactly what it says it is. Build a huge sail and have our Sun’s radiation propels us into the space. Scientists are already planning to propel space ships with this kind of technology. But why stop at the space ships? Why not “sail away” with the whole earth. Remember: once in motion, object (our earth) stays in motion until we or something else stops it. That would give us enough power to drift away into space until the need to change direction arises. To avoid asteroid hits would be one of those needs for example. In that case we would have to have some other means of manipulating Earth-Ship trajectory. One way would be to use anti-matter rocket propulsion system where we would just fire up our rockets as needed and basically repel-away from the objects. This way we would also be able to navigate the earth through the space as we wish. Some interesting fact: Right now, antimatter is the most expensive substance on Earth, about $62.5 trillion a gram ($1.75 quadrillion an ounce). To put that in perspective: To produce one gram  of Anti-matter would bankrupted whole world economy. Combining solar sail with anti-matter rocket system (depending on the size of course) should probably give us enough power and energy to escape Suns gravitational pull. There’s another non-conventional way to propel Earth-Ship would by bending (or folding) the space/time continuum to get us from A to B quicker. For example take a flat piece of paper and draw a dot on one end and call it point A. Next, draw a dot on opposite edge of paper and lets call it point B. If you have an ant that wants to go from point A to point B, you could simply have it run along the paper and eventually will get there. But, if you take the paper and fold it in half, two points will reach each other lot quicker. Another good analogy is piano on a carpet. If you want to get to the piano from one end of the carpet, why not just pull the rug towards you and piano will move towards you also. Just substitute carpet and paper with time/space. This is essentially folding of space/time. We’re probably few hundred thousand years away from technology that will allow us to do this. Just to be safe let’s say we’re 5 million years away from this kind of technology.

There you have it. In about 5,101,000 years we will be ready to move away from our Sun and look ahead where our race will drift eternally on a great cosmic journey. All that with 994,899,000 years to spare!
