Absolutely nothing. Most people believe that outer space is a vacuum, which contains nothing at all. However, this is false. When my grandpa worked for NASA, they told him the pressure in space is one millionth of a millimeter of mercury (within the heliosphere). Outside of the heliosphere, they told him it is one billionth of a millimeter of mercury. The heliosphere refers to the space contained within the Sun's magnetic field. It's rather large and contains all the planets, along with the asteroids and other rocks beyond Pluto. Anyway, the reason for this blog post is I watched a movie this weekend, called Sunshine. In one scene, a man was in the vacuum of space and missed an airlock. He quickly froze and his arm broke off. I asked my grandpa about the scientific validity of that scene and he said the scene was false. In reality, if you are in outer space without a space suit, the water in your body will boil. This is because the pressure is low enough to allow water to boil at your body temperature. So, you will die not from lack of oxygen or freezing, but from boiling. I have done further checking about vacuums and my grandpa is right - there is no such thing. No laboratory on this planet has ever created a 'true vacuum'. There is always something, no matter how hard they try. However, for convenience, it is still orthodox to refer to outer space as a 'vacuum'. But always bear in mind that there is some pressure, although minute. |

Absolutely nothing = vacuum = 99% of man's minds in Asia Friendfinder totaly devoid of anything of value. And then there is the 1% who share their thoughts here in the Asia Friendfinder Blog.

Aha... Do I spot a fault in your logic, young man? I have done further checking about vacuums and my grandpa is right - there is no such thing. No laboratory on this planet has ever created a 'true vacuum'. Do I not recall you saying in a previous post that just because scientists have not succeeded in achieving something that doesn't make it impossible that it exists ? (or words to that effect). Huh ?.... Huh ?.... May your God go with you.

Huh ?.... Huh ?.... I write stories and make logic mistakes sometimes. It's up to other people to catch my mistakes if I miss them. What I said about vacuums could be interpreted as 'there is no such thing as a true vacuum based on current knowledge'. I have to admit that is more correct than what I originally typed. From what I understand, the scientists can not get rid of virtual particles.
