In the video right after the break, the video suggests China is planning a mission for Mars in 2020. I assume they’re planning to send taikonauts to Mars in 2020 since the video is about how they had built a Mars simulation base for taikonauts on earth. I think this is amazing! Sending humans to Mars would be a new next biggest achievement for humans outside of earth! I can’t wait to see this happens in 2020!
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.
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?
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!
In the last blog post “Can Our Universe Expand Forever Or Expand Then Contract Later Just So It Could Die?” I surmised that the universe (our universe among many others) could have been expanding and contracting according to how it got fed with external energy — where such force would have to wander outside our very own singularity. Without such external nursery of energy, I surmised that our universe is like a quantifiable fish aquarium. Nonetheless, we all know that even a human being could be intelligibly randomized things at will — thus I think according to the universe we’re sentient beings are the AI (artificial intelligent). How about let me surmise some more and say that — what if the universe itself is a higher artificial intelligent force in which it could randomize things at will to expand and contract according to circumstances?
We human beings could only see the results of why the universe is expanding and contracting according to our very own whatever theories — but why would the universe do such a thing? What’s the point of expanding or contracting? Expanding to create more empty space for what? Contracting is like a suicidal attempt of killing itself off so the existence of the universe itself would cease to exist. Furthermore, perhaps the universe itself is like a smart TV or fishbowl/aquarium in which it was designed by a higher being. This way the purpose of expanding and contracting won’t be the burden with which the universe has to carry. This burden could be carried by the designer of the universe.
At this point, I think it’s more like a philosophical thinking than anything concrete on this matter, but it’s so intriguing nonetheless. In my opinion, philosophical or not, it’s rather important for us sentient beings to dig deeper into our origin. After all, if we could not remember how we’d come into being, then we would forever aimlessly forget about our root and forever lost — wandering in a dark forest (Three Body Problem’s sci-fi trilogy second book is also titled as The Dark Forest). I think only when we could figure out our true root of how we’d come into the existence, it is then that we could evolve to be something greater. Perhaps in such a quest, we could discover new technology to bring us to new heights; we could grow into even more capable and intelligent sentient beings.
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!
