Life in space

It is so severe environment in space. Cosmic rays, the hard gap of temperature, airless field, zero gravity, are some of cause of it. The main material of cosmic rays is proton, which has very high energy to fly alone. I`ll think about the effect of all of them to us, the lives on earth.

Cosmic rays are the high energetic radiation. It includes the atomic nucleus of iron, boron, beryllium, lithium, helium (what is said alpha particle, a having high kinetic energy helium4), and mainly protons. Generally it is said a particle needs so high energy to exist alone. On the other hand, nuclear reaction happens when the nucleuses collide and the event needs high kinetic energy because nucleuses repel each other due to electric power. So, if organic lives are exposed on cosmic rays, the cells cannot help but changing to abnormal, changing to cancer.

Airless field cause not only choking but also decompression sickness. Usually the compression of inner and outer is balanced in every static existence, but suddenly one becomes weaker or stronger, if inner became, inner is crushed or swells to balance with outer compression again. If outer, revers event happen. Airless field has no compression, so you might think our body swells and bombs when we are in space, but it is said our body don`t but are taken into decompression sickness. Our blood include atmosphere most of which is nitrogen, and abruptly removed the compression around it, the nitrogen become gas and stuff narrow pipes for cycling our blood to our body. For this, our body will go off when we are in space.

The hard gap of temperature is caused by airless field. Temperature is the motion or kinetic energy of air particles in other words. You might aware of that temperature doesn`t exist because space has no air. Yes, it`s alright. The energy of sun or other fixed stars come as a light and heat energy, but can`t remain in one point, only going. Our earth keeps the air around by force of gravity. The air is given energy and don’t go away so our planet keep this comfort temperature. In space, the energy doesn’t stay around and comes directory. But, however high or low temperature becomes, our body won`t burn or freeze because space has no material. The oxygen is needed to burn, any carrier is needed to take heat away. Therefore, we wouldn`t die immediately if we were put in space, and we would die from choking rather than the effect of temperature. According to really happening, a space clue had got to space without space wear and was helped after 15seconds. The fellow took artificial breath and he barely kept his spirit in this world. It`s said if he had been in space more than 5seconds, the result was different.

Zero gravity field effect on our body and the shape of plants. Plants control the direction of root and leaves by gravity. the effects we would get are the disorder of body fluid, bones and muscles. Usually fluid gather to the lower half of the body, but come to higher. Bones and muscles are trained by gravity but it become weaker.
