    Interplanetary and Interstellar Space Travel: Distances Between Exoplanets, Stars, and the Search for Alien Life

    My other blogs are:
    Expensive trips always mean great fun with your gal...what about a $108.5 trillion dollar vacation? Barry White anyone?
    Is interplanetary travel possible? Maybe yes and probably no, depending on your view and how desperate humanity becomes to explore the cosmos. What about aliens visiting earth? Well, this is even less likely given the vast distances of stellar objects are from one another within the universe, coupled with the fact that literally everything we see for billions of light years is lifelessness and silence. So below are some mind benders. The numbers are all accurate....really accurate, as in, the best scientists of the entire Earth came up with some of the numbers and I did basic math to generate numbers that I could understand, because who in America knows how long a kilometer is compared to a mile? Or how truly fast light speed is per second versus miles per hour? Doesn't it make sense to make your articles' facts and figures understandable to your average or general audience? This is America, so use American measurements! Don't geniuses ever pay attention to English Composition class in high school and college? (Um, no, they like feeling smart, so they make us feel stupid). So here are a lot of really insane numbers that the everyday American should be able to comprehend without using a kilometer-to-mile online converter. Europe can go fly a kite on a warm sunny day!

    1) One light year = 5,878,625,373,183.6 miles 
     
     
    2) × 36 light years = 211,630,513,434,609.6 miles from Earth
     
     
    3) 211,630,513,434,609.6 (miles away) ÷ 35,500,000 (speed in mph) =5,961,422.913650974647887323943662 hours travel time

    FACTS:
    Gliese 581c is 20.3 ± 0.3 light years away and is totally uninhabitable for human life since it's 5.6x Earth's mass. Although extremophilic life might be able to exist on it in the future if water were to form on the planet, the chances are slim to none since water doesn't usually form under such high gravity. Scientists realize that even if they could travel at light speed, there really aren't any habitable planets anywhere near our cosmic neighborhood anyway, so astronauts would be stuck traveling for centuries even at light speed. Although if humanity were truly desperate, some exoplanets are better than others. There have been discussions about terraforming, where if we develop highly advanced terraforming capabilities instead of trying to go light speed, we could simply transform a planet like Mars into a more suitable Earth-like planet for human habitation. Problem is, Mars has virtually no atmosphere and we can't seem to find any planets nearby which possess a mass similar to Earth's so water and life can form. If Mars had an atmosphere, humans would still struggle with its low gravity, as it has 1/10th Earth's gravity and size, but Earth is already so small. Now if the gravity of a selected planet did not exceed 2 Earth masses, then it might be possible to colonize it after extensive terraforming. However, there is still the problem that if a person weighed 130 lbs. on Earth then s/he would weigh 260lbs. on such a planet. On Gliese 581c, a 130 lbs. person would weigh a crushing 728lbs., an average-sized (7,700 lbs.) elephant would weigh over 43,000 lbs., a Giraffe would not have the heart capacity to pump blood to its brain, and vascular plants would fall over and die. The list of complications just stretches on and on.
    --------------------------------------------------------------------------------
    HD 85512b is a cozy 36 light years away and is the most promising candidate for human colonization so far, as it is only 3.6 Earth masses (vs. Gliese's 5.6 LY). But still it is a not an option for humans or animals because on this planet a 110 lbs. woman would weigh 414 lbs. and a typical 180 lbs. man would weigh 648 lbs. No human or animal could live on this planet unless we had technology to reduce mass. The gravity is also far too high for water to form and plant life would be crushed. Only low-lying plants could survive.
    --------------------------------------------------------------------------------
    Even at light speed it'd take decades, centuries, millennia, and eons to reach some of the nearby planets, stars and neighboring galaxies to Earth. Most astronauts today don't get enough experience to be allowed to fly any space shuttle until they are in their late 40's and 50's, and even a light speed astronauts would arrive to HD 85512b as geriatric old men. Kids would have to be selected and groomed for space flight at very young ages and prepared to fly away from Earth, which is unrealistic since most kids would never want to leave their families forever and even if they did, child rights activists would inhibit this selection process, probably saying that a child could not be expected to make such a mature decision or capable of understanding the magnitude of such decisions.
    -
    It's either that or take the chance that the adult astronauts would arrive to the destination dead or feeble from old age, perhaps even being unable to do the hanky panky for colonization! This means that even if we could travel at .99c a starship would still have to be a generational ship, where the original astronauts would become feeble grandparents and hand down responsibilities to their sons and daughters and then they again to hand down responsibilities to their children, who being prepared by the fathers and grandfathers to colonize the planet(s) they stop to colonize. These children would continue the legacy of study and colonization by hopefully building new human civilizations and link planets like pit-stops for other future travelers.
    Going light speed means we'd
    essentially become this
    This is totally unrealistic, especially since the whole generational ship idea is flawed in about a ba-gillion ways, as the size and mass of such a ship being the most obvious flaw, there's also the fact that about 101% of humans could never live in a cramped ship with no freedom to move for decades or their entire lifespan. In fact, designs for realistic spaceships today are so cramped that they are more cramped than World War II submarines, which are already so small that you cannot stand fully upright in about 90% of the submarine. People in prison cells would have much more free space to walk about then a spacefarer would. Assuming that we figure out how to create a spaceship that's roomy and cozy enough to spend your entire life in without going insane still does not include the fact that the speed of light travel isn't possible at all according to Einstein. And assuming it is, they is also the problem where cosmic rays, gases, dust, and even atoms all become deadly forces even at 1/10th the speed of light. Conceiving of traveling at only 5% the speed of light is equally absurd, let alone 1c.
    -
    Read my article called "Project Daedalus" where American scientists speculate that the ship could reach speeds of 70+ million miles per hour (12% light speed) but they don't have a clue of how to protect the ship when going that fast, although they hope in the future humans can develop a sort of shield technology.
    To finalize, it is because of these factors that any respectable astronomer would agree that humans are mere ants. A 2010 study by astronomers estimated that the "observable" universe contains 300 sextillion stars (3×1023///300,000,000,000,000,000,000). The observable universe is about 46 billion light years in diameter///270,416,767,166,445,600,000,000///270 sextillion miles), and is literally just another way of saying "what we can see so far all around us." And let's say that we all band together to make that starship and eventually we do meet aliens...given our luck, they'll hate us and want to either eat us or eradicate us. As if any advanced alien civilization would be like E.T., take a look in the mirror. There's nothing noble to see there, so why should there be in any alien? No foreign creature would have an inherent desire to respect our desire for continued life, we don't even have that for each other.
    -
    If anyone ever wonders if aliens can visit earth or that we might someday visit them, you now know how the odds are not remotely in our favor for either of those possibilities. We'd still have to build ships where many people would spend their entire lives and die and their kids live and die and so forth over and over for many generations....at the speed of light... just to make it to anywhere in. Not even photons (light) can travel the universe in any reasonable amount of time, as my graph clearly demonstrates, but then again, beams of light aren't doomed to die like humans are.
