Space Elevator or Space Tower?

I asked this question “Japan is planning to be successful in making a first space elevator, can Japan realize this dream? Can space elevator really help us get around in space better than today’s spacecraft propulsion technology?” on Quora and I got an answer with a very cool video which linked by a Quora user Bert Murray.  Check the video out right after the break.  I think you’ll like it, and you could learn something about space too.

Why We’re Alone?

Just a quick thought on why we’re alone or at least we think we’re alone!  If you have read the Three-Body Problem sci-fi trilogy, then you may compel to agree with the author that other aliens don’t want to be seen at all costs!  The idea is that once an intelligent world is being discovered it could be the end of it.

Imagine an intelligent world that is being developed to the point that it needs to colonize other planets to sustain its population and civilization.  This world thus would go out of its way to strip resources of other planets and stars.  The hungriness of such a world would not be stopped and it would grow infinitely until their technology got so great that they could outstrip an entire galaxy for resources.

Aliens might not want to see such a world to develop to such capacity that would compete against their own world, and so destroying an undeveloped world as fast as possible would be the easiest thing to do.  Of course, we could not know what the aliens would think.  Perhaps some aliens out there prefer peace over war.  Perhaps, some aliens prefer to see the whole universe teems with colorful civilizations.

Personally, I think there could be aliens out there that are so developed and advanced to the point that they could hide in plain sight and we just don’t have the technology to see them.  Some aliens could be so advanced that they don’t need to colonize and change the ecosystem of a planet for survival because they could modify themselves to fit into any environment!  For all, we could know they could fly in a poisonous gaseous environment and would still feel like taking a stroll on a warm Sunday afternoon.

As we’re looking for a Goldilocks solar system to test our theory of finding existing alien life, these aliens may just be in plain sight but we won’t know it as we’re too focusing on the wrong environment.  In short, we’re guessing but we could be off for miles.  Perhaps, aliens don’t live in a Goldilocks environment?  Perhaps they are and they have the technology to prevent us from seeing them or seeing their solar system?

I Think It’s Stupid To Think That It Takes Only 98 Healthy People To Sustain A Human Species

So, I’d just finished reading “How many humans would it take to keep our species alive? One scientist’s surprising answer” article and I was amazed that his answer is just only 98 healthy people.  Afterward, I scratched my head in doubts.  Obviously, these 98 people would band together to produce more offsprings so the population could grow larger.  Also, we could imagine that these 98 healthy people are the sole survivors of the planet earth since an apocalyptic event had wiped everyone else off the planet earth.  So, is it true that it would take only 98 healthy people to start the new seed of a lost civilization for generations to come?

I don’t think it is possible for 98 healthy people to redevelop a lost population/civilization!  In my opinion, if an event that could wipe out 99.999 percent of earth’s healthy population, how could we be so sure that the other 98 healthy people would last?  Furthermore, a much smaller group of people is going to be more susceptible to extinction since any number of unfortunate circumstances could reduce this small group into an even smaller group.  Of course, you can argue that these 98 healthy people are special since they survived the apocalypse and got a very good protective shelter such as they’re escaping the planet in a very capable spaceship.  Then again, the universe is so huge which harbors all sorts of danger — how could one know that these people would survive through one generation?

Of course, you could argue that space is very safe for a generation of people who travel in a very capable spaceship to begin a repopulation program which could last for generations to come.  Here I begin to doubt even more!  How could anyone know how long a spaceship would last?  Unless you have a crystal ball, I don’t think you could really know how long a spaceship would last.  I imagine a spaceship got some moving parts and all sorts of things that could go wrong at any moment.  I also imagine that space is a very lonely place, and so these 98 healthy people could suffer all sorts of depression.  It takes only one crazy depressive person to dwindle this group into a smaller group.  Thus, extinction is very near and dear!

I don’t like how one would think it takes only 98 healthy people to repopulate earth or sustain human species because this would encourage the crazies to believe that the other 99.999 percent of earth’s population is dispensable.  My argument is very real for the reasons I stated above.  Basically, I don’t think 98 healthy people could sustain a human species for there are too many variables that could dwindle this small group.  From human emotions to outside variables, any one of these variables that turn negative could greatly reduce this small group.  My answer is that I don’t believe 98 healthy people could actually sustain a human species!

Can Our Universe Expand Forever Or Expand Then Contract Later Just So It Could Die?

From Einstein E=mc^2 to the conservation of energy theory, these concepts agree that energy cannot be created nor destroyed — after all these energies existed since singularity (even before the big bang).  Thus, if I agree with these concepts, it means everything within this universe can be deconstructed into the smallest of the smallest possible units, and each of these smallest units could be counted individually in a way that if they’re to be reunited they could be constructed into the whole universe again.  The question is if this is the case, is our universe static in quantity?

I surmise there is another possibility!  What if the first scenario is true but there is one exception!  The exception is that outside of the singularity there is a bigger container that could feed more energy into the already constructed universe which we’re living in.  This could mean the quantity of our constructed universe could be changed according to the limitation of the larger container which contains our universe.  If this is the case it could mean that our universe could be shrunk in size and quantity by somehow shredding off existing energy and feeding the lost energy back to the larger container.

Relatively then, from within our universe, it could be that our universe is infinite since it could be expanded forever or be shrunk forever depending on the situation.  We don’t know the limitation of the larger container so we could only see the direction of our universe as an infinite expansion or infinite contraction relatively!  There’s a saying that nothing could last forever, and so we know that even the sun and anything else that exists within our universe got an expiration date.  I suspect that our universe could be expanded forever until the larger container stops feeding energy to our existing universe which would then allow this universe to contract and die off eventually!

Could We Colonize Space By Rearranging The Solar Systems?

Could it be that God truly exist?  If God isn’t really existed then luck must be it that earth could actually harbor life!  Our planet earth got really lucky in a way that it is not too close to the star (i.e., the sun) and it is not too far from the star either.  Other dead solid planets are not so lucky as they located too far from their star or too close to their star, thus their surface would either boil or freeze to the extreme temperatures.  Such extreme conditions would prevent life as we know it to exist.  Of course, there would always be the exception, but such an exception would be nothing like us humans!  Such aliens would not have any semblance to the traits that us humans are familiar with such as how life has existed here on earth.

I guess it’s safe to say that earth is either a miracle from God or it is truly lucky.  As our advanced telescopes peer into the endless darkness in space, we have discovered so many solar systems and galaxies.  Although we’ve found so many planets and stars and solar systems and galaxies, it seems the more we found the more we instill a belief in ourselves that we’re alone.

Through current scientific methods, we could only guess that there are some planets out there that could harbor life.  Perhaps we think such planets are locating in the comfort zone of their solar systems, thus providing the chance that these planets could harbor water.  Here on earth, life exists because of water.  We’re thinking that water on other planets too may allow life to go through an evolutionary process — developing alien life in the process.  Nonetheless, we could only guess and not so sure about our guess until we could deploy some sort of drones, robotics, and satellites to such planets.  Even better, we could deploy humans to such planets!

Unfortunately, the solar systems and planets we think that could harbor life are way too far for earth’s current technology to reach.  For an example, we could try to launch a rocket fuel vehicle toward Alpha Centauri system.  According to Earthsky’s “How Long to Travel to Alpha Centauri?” article, it would take 78,000 years for our current rocket fuel vehicle to reach this space system.  According to Wikipedia, Alpha Centauri System is the nearest star system to our solar system which is about 4.37 light years away from our solar system.  So, it seems our current space technology is way too slow for space traveling because even the closest solar system would take 78,000 years for a human space vehicle to reach it.

At the moment we could not be sure if life is actually existing anywhere in space.  We know for sure though life is existing here in our solar system because the earth is teeming with life.  If we want to confirm that life is actually existing elsewhere we have to develop space vehicles that could travel much faster.  Preferably, we want to develop space vehicles that could travel near the speed of light.  Only then that we could travel to Alpha Centauri space system in 4.37 years or so.

What’s the point of my rant so far?  Well, imagine an alien race that could be so advanced that their technology allows them to modify any space’s solar system to the way they like it.  Imagine the ramification of such technology!  Just imagine each planet and star like a pool ball on a pool table!  Imagine a pool table’s holes are the black holes, and if each ball got too close it would fall into a pool’s hole.  In reality, if a planet gets sucked into a black hole, it would be destroyed into pieces, I think.  Will the black hole spit out these shredded planets and stars later?  I don’t know!  Nonetheless, the idea is to imagine that space is dangerous and comfortability is very, very rare!  So if each pool ball travels too close, each pool ball would collide with one another.  In reality, a planet collides with another planet would be on the scale of the doomsday disaster.  If a planet collides with a star, it would be the destruction of the planet itself.  So, this alien technology that could modify the layout of the solar system would create the condition to harbor water and provide life as we know it.

Now, if we could develop such technology here on earth, we could go out into space and rearrange any solar system to our liking, making other planets to support life so we could have more earthlike planets out there in space.  This is one way I think we could colonize space and allow human species to exist much longer than the earth itself.  For an example, our earth could be dying someday, and so without such technology, we won’t be able to escape the dying earth — in such a process human species would die along with earth.  Instead of dying along with earth, humans should try to come up with technology that pushes planets and stars around to rearrange the solar system to how we like it.  It would be so easy to shoot the pool balls around on the pool table, but I guess it would take Godlike effort to do so with pool balls that are as large and as heavy as the planets and stars in space.  Furthermore, if the effort takes too long, the solar system itself could be destroyed!

Cities of the Future Could Be in Space, And These Won’t Look Like Any Real Estate We Know Today

The concept of real estate is largely depending on how we are glued to earth!  What will it be if in the future we could forgo the glue of earth altogether and build a city in space?  The space elevator is a concept that is in science fiction realm, and today we don’t have anything like this yet.  Nonetheless, this space elevator concept could become true if we got the right materials and plan to make it a reality.  Once humans travel through space easily as if how one would take a bus or a train on earth, then the idea of living in space becomes rather mundane.

We humans always think that we need another planet out there to be a second earth, but what if the cost of building a city in space in a modular fashion in a sense that space elevator concept could expand into a space highway and such — wouldn’t this be more doable and cheaper and time-saving than trying to find a second earth?  So I would imagine that a highway system in space would function similar to space elevator but the system itself would be more expansive.  After all, a space elevator could be a quick fix for a short distance from one point in space to another point in space.  Perhaps, space highway is like a bigger, more durable space elevator, and the spaceships that travel through this space highway system won’t need to use a self-powered propulsion system to traverse quickly from one point in space to another point in space.  Wouldn’t this be fuel efficient?

Of course, we could argue that space highway is kind of stupid if spaceships could just fly freely in space without needing to stick to an asphalt.  Nonetheless, space highway could function as fuel saving mechanism/system and much more.  Spiritually, space highway could function as a system that turns the idea of space city into a real community/city.  Imagine how much more expensive to build a small earth in space, and so it’s not wise to do so.  Instead, each spaceship could act like a car, home, restaurant, and so on.  The space highway then acts as a highway system that connects the necessary points in space to form a loose space city system.  From this highway, a home in space could fly from one point to another without needing to use any fuel unless the home is going to fly off the space highway system.

I think a concept of loose space city system — if it’s a reality — could turn the idea of owning a piece of real estate upside down.  After all, everything would be floating in space and won’t stay put.  Furthermore, even the highway itself could be floating continuously, albeit that it would stay in the same large vicinity in space.  Once people actually live in such a space city, people won’t be able to differentiate a house from a car, a car from a restaurant, and so forth.  After all, humans in space would be in a spaceship most of the time.  So, humans in space would think their spaceship as either a home, a car in a space highway system, a business location, a restaurant to invite other humans to come to dine and so forth.

In summary, I think when people begin to think a city in space in a loose space city system, the real estate concept would be completely different than the one that we use for cities on a planet.  Of course, humans don’t have to stick to only one type of space city.  After all, we could find a second earth and create even more cities from far away in space.  In my opinion, a loose space city system could be the extra real estate for a closeby planet.  For an example, let’s say earth would run out of space and people could create extra space real estate by creating a loose space city system just right outside of earth.
