| Life in Space Problems to Ponder |
Gravity and air pressure are vital to everyday life, yet if astronauts were to be launched into space these two factors that people take for granted in their everyday lives would become fatal issues if left unresolved prior to long term space travel. The thing is, it's actually earth's air pressure and gravity that hold blood and guts under the skin, but most people do not know this...they think their skin holds their guts in, which is dead wrong. The skin does virtually nothing to hold human bodies together, but rather is merely a shield against harmful elements that exist outside of the human body. While people talk about how scientists need to find special fuels to power their wild spaceship designs, actual NASA employees are trying to develop ways to simply live in outer space at all, let alone to fly at near-light speeds in fancy antimatter powered starships. 
Atrophy In outer space and under low to zero gravity, muscles and bones can become atrophied due to lack of use, since zero gravity environment are extremely easy to maneuver in, causing the muscles to become weaker. Bones under atrophy as well in their own way as they lose bone tissue from similar non-use as the muscles undergo.

| Uranus King of the Ice Planets |
Uranus is one of the ice-planets, along with Neptune and Pluto and probably more are nearby that we haven't seen or discovered new things about. These planets primarily consist of methane, ammonia and water. Uranus' water is thought to be broken down into its hydrogen and oxygen parts with the methane and ammonia, creating a toxic ocean of mostly frozen chemicals. And although it's called an "icy" planet, its core is thought to be between 8,540.33°F - 12,140.33°F (5,000-7,000 kelvins). It's so cold because it has a low thermal flux (inner heat does not radiate out of the center), making the surface extremely cold, reaching lows of -224°F and the intensity of sunlight felt on the surface is only 1/400th that of Earth (no wonder it's so cold). What's even more awkward about this planet is in the picture to the left, depicting the polar ice caps on the planet's sides and the planet itself also spins north to south, rather than east to west as on Earth. 
Another confusing quirk is the magnetic field, which does not originate from the planet's geometric center due to the planet's tilted axis (at 59°)...and although I don't like quoting Wikipedia, they explained it well, stating that "The magnetic dipole is shifted from the center of the planet towards the south rotational pole by as much as one third of the planetary radius. This unusual geometry results in a highly asymmetric magnetosphere," http://en.wikipedia.org/wiki/Uranus#Magnetic_field. In other words the planet itself is much more tilted than your average planet, and due to this asymmetric geometry it also has an asymmetric magnetosphere. At the very least it makes sense, since the two correlate.

| A New, Nearby Earth? Gliese 581C Gliese 581C- 5.6x Earth's mass means it cannot support intelligent life like ours here on Earth, only simple life like low-lying plants, mosses, perhaps bacteria. All this is assuming, however, we ever managed to get water on the planet and terraform! Sounds....ea...sy... |
(Read caption on above) Here you are! Since the birth of astronomy centuries ago, here you go! This is the best planet we have discovered as of 2012 that could possibly support some life if we can dump a few oceans onto it, adjust its temperature ranges, and decrease its gravity substantially. How stooooopid, haha. People like to day dream though, and you can't blame them for imagination, and they sure have a lot!Yet it begs the question, "After centuries of science this the best we have so far?" So, ready to leave Earth for a few centuries of terraforming and building a new civilization of humans that you don't even like? If there were hot alien babes to teach the meaning of love to nearby then whoa, I'd be in that for sure! Well, you should still say no even to hot alien babes, because unless you want to die from the massive gravity of Gliese, then I suggest you relax and do some more reading. It would seem that these are some of the questions plaguing astronomers right this very moment...Is this a new super Earth that we could colonize some day when we have better technology? What scientists mean by statements like this is simply, 1) Is the planet as closely similar to Earth for colonization without terraforming? and, 2) Will the planet's gravity crush humans like road kill? 
People need to cool their heads in some water when they get excited about Earth-like planets because this is what we continually find. The more we study the universe the more we realize how terrible we are for ruining our own planet, and the more we are forced to face the sad fact that we cannot maintain our current lifestyles. The human way of life is so toxic to the planet, I say, what's the point in going to another planet? We're simply going to ruin that planet anyway. Is our current lifestyle truly this happy and awesome that we need to find another planet to ravage? Is a simpler life really that terrible? No, it is better, but you have to change what you live for in life. Simple people like simple lives because they have simple desires, like a wife and children, a good family to spend time with and some great home cooked meals. The only way the human species will survive this current technological lifestyle is if we all decide to become space travelers and attempt to build starships to colonize other worlds. |
| Some stars and black holes bend space time so much that some scientists think that if space and time really are one 4-D container, then gravitational forces of this extreme magnitude probably bend time along with space. Yes, black holes bend space, and because space and time are one entity according to Einstein, then wouldn't time warp also? Hence, wormhole time travel. |

| This is my face to the partial Time Dilation formula below |
A brief example: Humans experience a rate of time according to how the earth is experiencing time as it zips through space at tens of thousands of miles per hour. The earth is large enough (mass and gravity) that it bends space a little, causing it to curve some. In essence, we experience days and hours and minutes according to the earth. This does not mean that if a minute on earth passes that several minutes or a fraction of a minute might be experienced elsewhere in the universe. Time always travels at the speed of light (of time), however our **experience** and **perception** of it can speed up and slow down. 1 minute is always 1 minute, yet when Clint Eastwood looks at the slow moving Charles Bronson, 1 minute might be hours of movement for Charles from Clint's eyes, and vice versa. |
| If only Ultimecia had used "time dilation" instead of "time compression," then she could have moved super fast relative to Squall and watched his entire life dwindle away in seconds. Then destroy the universe! Yippee skippee! |
