Being an astronomer

Alright, lets get real, you are a famous scientist who just discovered that a huge meteorite is heading towards us and it will collide with earth in exactly two hundred years. A few days later satellite shows the meteorite changing its course and you feel so relieved. That is what it feels like to work in a space observation lab, everyday, you will have a lot of false alarms popping up on the screen. Well its fun right?

Astrology is also one of my interest, in fact, i dare to say that its on top of the my list. Being an astronomer is really exciting as you get to explore the deep space through powerful telescopes, you can also watch the stars and other galaxies, which really sets my mind thinking, are we really alone?

To me, being an astronomer is a perfect job, you get to sit in a well equipped laboratory, you also get to travel to different destinations to observe stars(most destinations are really beautiful), and on top of that,you will be the first few to be informed or discover new planets of even galaxies!

can A.I really behave like a human mind?

Well, all these years, humans had been hoping to create smarter robots to serve mankind , in news throughout the years we can saw the changes in how robots are programmed using A.I technology. some A.I s are so clever that they are used in modern computer games, creating a more challenging and engaging game. However, one question still exists, can we really create a A.I that can truly behave like a human?For days, i had pondered over this question on why the scientist were still unable to find the key to creating the perfect A.I. . The answer is really simple, it is to find out how to be human, many of my friends laughed at my answer, however they were all taken aback when i asked them how to be human.They did not have an answer, neither did the scientist, nor most of the people on earth, i daresay 98% of the human population do not have the answer.

So, what does it take to be a human? How to be human?

The feelings i feel when i gaze at the sky

Every night,i take some time off to gaze at the sky, many people may call me crazy for staring ,but every time i look up, i can see the stars, somehow they always remind me that i am real, still alive. As days passed by, i feel that i am becoming more and more lifeless, attending school every , going to st johns which don't really enjoy, it all really adds up to the stress which is really causing me distress.However, whenever i stare at the sky and the stars, i feel recharged, i feel real and alive. Deep inside me feel that i don't really belong in this world, i really long that one day i will be able to leave earth behind me and set off, seeking my own universe, a place where i really belong.

Human's origin?

Where do humans really come from? Are the apes really our ancestors?If so, how can we explain the fact that scientist found substances similar to our DNA on a meteorite?These substances are not known to exist on earth.So what does it mean then?Do we humans really originate from somewhere deep in space?However, this idea may contradict with the scientist's idea of evolution.

Personally, i do believe that humans originate from a far away place, deep in space, because life cannot appear out of nowhere, can they?

The end of the world 2012 part 2

The second part will be on the possible threats the earth is currently facing, these threats may endanger us in many ways
,it may also lead to the destruction of earth.

Many people claimed that the Mayan prophecies about 2012 are untrue, however, there are things which are happening behind our backs.
Recently scientist observed unusual activities on the surface of the sun,usually, the sun produces a lot of solar flares which bombard the atmosphere of the earth, resulting in northern lights, but recent observations showed a decrease in solar activity.

The scientists said periods of inactivity are normal for the sun, but this period has gone on longer than usual.It could be that the Sun is just saving up for a massive amount of activity in 2012. Approximately 100 scientists from Europe, Asia, Latin America, Africa and North America gathered June 1-6 to talk about "Solar Variability, Earth's Climate and the Space Environment." - and they are thinking that 2 years without a sunspot is perhaps too long.

So perhaps one day, the sun may release its energy and who knows what may happen?Another ice age?The atmosphere collapse?Its all waiting for us to find out in 2012

-a man once said :
who knows what may happen in 2012,
its either the end, or we may just sleep through that day ,
waking up the next laughing at ourselves for believing in the doomsday?

This is only one of the identified threats , more will come on part 3.
