Dinosaurs Extinction

Dinosaurs are so interesting to me, their life, size, habits, diet even their extinction!


the large scale of extinction of K-T, sometimes it seems that a very large Crater hit the Earth and making a tremendous explosion and creating clouds of volcanic dust over the sky cousing the long period of none sunlight, is the reason of Dinosaurs extinction. but there is some debt yet.



another fact is the Comet Shoemaker-Levy 9 who hit the Jupiter in July 1994, it wasn't any single collision, it was a series of them. so if there was any comment coming to the Earth at K-T time there were some main hits and other smaller hist, which happened not at the same time may be with a several years of period which can make enough time to change the climate by storms and the volcanic dust clouds , eliminating plants and starving the animals.
this can be the connecting point of these two facts.

Question marks ???

There are a lot of questions in my mind about the ET life. I 'm , gonna to share them trough this blog, at least I can organize my thoughts.
the first is how can a ET life can be distinguished?
the only example of life we had seen is Earth living mechanizes. I say the carrier of life in the Earth is Carbon, what about the other planets?
the other possible carrier is Nitrogen. My assumption is based on the properties of this two elements properties such as Combination Ability with other elements and the possibility to find them in semi calm situation.
* semicalm situation : not so high and neither so cold temperature ( the Energy is different type ), not high amount radiation and so on, such as the situation on the Earth surface or beneath of Earth oceans.
please take a look at Periodic Elements Table.
second the world unfairness: this world is unfair, you can see the deserts and sees, the amount of water is not equally spread. the same situation exist for other elements and phenomenons at this world. the Energy, different elements, the roads to reach some resource, also in one word the resources are not distributed all over the mater world fairly. based on this talk, there is possible to ET Civilization Trade, Competition, Taking under domination, Ownership, Transportation, Communication and Money would be meaningful.
so how could these ideas be for ET civilizations?

the Milky way

it's know that we are living in a galaxy. a spiral galaxy just like a lot of other galaxies in the universe.but if dose anybody see the other side of our galaxy?
only at nights the galaxy's stellar arms can be seen. Let me explain with a more simple example. if somebody in in a car he can't see the car, only if he comes out and takes a loot at the car. so if we are in a galaxy called milky way and since now nobody gets out of the galaxy to be able to see the hole galaxy. the picture in the right corner is the meteor streaks across the sky form the Earth. [see the page]
One day it would be possible to make journeys just in few milliseconds around the milky way. But how? I know ;) something just like "Google Earth" yes it's possible it's enough to have the first pictures from the other side and hole view of milky way.
No human made thing is got away or leaved the solar system yet except "Voyager 2". only a few signals were received from it a couple of years ago after finishing it's mission and getting out from solar system showing it's working. for more information about Milky Way click here.
The left corner picture is a Artist's conception of the spiral structure of the Milky Way with two major stellar arms and a bar[see the page]. Milky way has to major staler arms, more than 100K light-years length and more than 1000 light-years thick, 200 up to 400 Billions of stars and is about 13.2 Billions years old.
Also there is some nythological explanation for the name of Milky Way galaxy.
In Persian nythology galaxy is called the way of straw carrier . and the milky way is called the same as the milk poured way. Ancient Armenian Nythology called the Milky Way the "Straw Thief's Way". According to legend, the god Vahagn stole a straw from the Assyrian king Barsham and brought it to Armenia during a cold winter. When he fled across the heavens, he spilled some of the straw along the wayin[see the page]. The Greek name for the Milky way is derived from the word for milk gala. One legend explains how the Milky Way was created by Heracles when he was a baby[see the page].

from what to what!

while looking on the earth surface I learn about the above of sky :)


looking to this , I think about


these.

how amazing is the universe and how unknown is it, and what amazing and unexpected relations are between them. I must look more carefully through things around me.

To Readers

First I categorize the idea which I have, second I do research about the issue. then I let me some time to understand completely the articles which I read. After that I do imagination about the subject then I start to write a draft with main points. then reordering the points or even sometimes change their order or add some new or delete ones, so I start the main writing process. it took time and it's the reason that my blog gets updated so slowly. My own jobs and duties must add up and then the updating times makes sense ;)
Thank you again for your patience, interest and courage.

Explanation

Thanks to all of you, who read my first blog
whenwemeetforeigncivilization.blogspot.com
may be it seems that I 'm updating my blog so slowly. But at first I must say I have an idea in my mind, and I'm gonna to share it with you, I mean the hole story. The hole story is meeting aliens and foreign civilizations, the thing which is in my mind all the time ;) how they could be, how would be the meeting process, what are the advantages and challenges of meeting alien civilization or things like that, always I think about those things.
I have my made universe inside my mind. Before I get able to tell the main stories I must explain some issues such as meaning of life, the meaning of logic and intelligence, the phenomena of to be civilized and so on. So I started my blog with such articles, I hope these aren't boring and would help me to explain my ideas better.
In this blog I would discuss the ideas, so I'm waiting for your comments, criticisms also helps and ideas.
