Sekelompok ilmuwan berhasil melakukan simulasi yang menunjukkan bahwa galaksi Andromeda terbentuk dari benturan antara dua galaksi kecil.

Menggunakan komputer dengan kemampuan tinggi di Observatorium Astronomi Nasional China dan Observatorium Paris, tim peneliti internasional melakukan simulasi tentang bagaimana Andromeda berkembang dari waktu ke waktu. Dengan simulasi ini, peneliti menggunakan delapan juta partikel sehingga mampu memproduksi sebagian besar properti Andromeda, seperi bintang, cincin gas, dan debu. Hasilnya, dua galaksi kecil diperkirakan bertabrakan sekitar sembilan miliar tahun lalu dan kemudian membentuk Andromeda seperti saat ini.

Selama ini, banyak ilmuwan yakin Andromeda terbentuk karena sebuah benturan antara dua galaksi kecil. Sayangnya, mereka belum bisa memastikan teori ini. “Banyak astronom berpikir galaksi Andromeda merupakan hasi dari gabungan. Namun, pemikiran ini tidak pernah diuji coba dan ditentukan waktunya,” kata Francois Hammer, ketua penulis jurnal, Astrophysical Journal, yang mempublikasi simulasi tersebut.

Hammer mengatakan penelitian ini juga bisa memberi pemahaman terhadap formasi galaksi kita sendiri. “Tidak berarti Bimasakti tidak dapat terbentuk dengan cara yang sama. Mungkin saja. Tapi, mungkin terjadi jauh lebih awal,” tutur Hammer.

Andromeda adalah galaksi berbentuk spiral yang paling dekat dengan Bimasakti. Galaksi Andromeda terletak di langit utara. Namanya diambil dari rasi bintang Andromeda yang terletak di tempat galaksi ini terlihat dari bumi.

Galaksi Andromeda bisa dilihat dari bumi dengan mata telanjang dan akan tampak seperti kabut tipis di langit utara. Jika diamati dengan teropong, akan tampak bintang-bintang redup di tepiannya. Galaksi Andromeda dan Bimasakti bersama Galaksi Triangulum, dan 30 galaksi kecil lainnya tergabung dalam sekumpulan galaksi yang dikenal dengan Local Group Galaxies.

Berjarak 2,5 tahun cahaya dari rasi bintangnya, Galaksi Andromeda mendekati Bimasakti dengan kecepatan sekitar 100 km per detik. Sehingga, ilmuwan memperkirakan Galaksi Andromeda dan Bimasakti akan bertabrakan sekitar 4,5 miliar tahun lagi.

Dampak benturan ini kemungkinan akan membentuk galaksi eliptik raksasa. Namun belum diketahui bagaimana nasib bumi dan sistem tata surya kita jika terjadi benturan ini. Ada kemungkinan sistem tata surya dikeluarkan dari Bimasakti atau bergabung dengan Andromeda.

mbmb ~ my best mood booster . . . .

he always can make me smile,
he always can make my mood boost,
he always can make me strong,

but . . . .
now everything has change,
he didn't same again like before,
he's different now!

it's because . . . .
i make a distance when he and i so close,
i'm too kind, i am thinking of my friend's feel when she know that he and i so close,
i make so far distance with him,
i seldom reply his message,
i seldom reply his comment in fb,
i never send message to him,

and now i regret what i did.
now . . . .
he and i like a strangers,
he never comment in my fb again,
he never sent me messages again,
ya, i did it because i want that happen, but when it happen i feel sad.

althought, when i sent him a message,
he stiil reply it,
he still share a joke with me,
he still can make me smile,
he still can make my mood boost,
but it's different!
i dunno, but i feel there's something different in his message,

and now i miss the old him.
i miss....
messages from him that he sent all day, from morning until morning, from night until night,
the way he makes me laugh with his joke,
the way he makes me confused,
the way he makes me happy,
the way he give me motivations.

when i feel sad or my mood down,
i always sent him a message,
i always wish that he can make me smile,
i always wish that he can make my mood boost,
and he always did it!
i feel comfort when he did it,
i wish he always here beside me,
i don't know, am i love him? (thinking)

if . . . .
i became more egoist,
i don't thinking of my friend's feeling,
i know him before her,
don't know what will happen now,
will i became her best friend?
will i became her girlfriend?
don't know! i can't imagine about it.

I Miss The Old You

this is something i wrote about how i feel. alot is going on in my life right now, and this is one thing that is happening. i finally decided to write this poem because of a poem someone wrote titled: I Miss The Old You. it was really good.


i miss you.
i miss your laugh.
i miss your smile.
i miss your friendship.
i miss you.
i miss the way we used to talk.
i miss the way you used to laugh at eveything i said.
i miss the way when we could act like kids,
and not even care.
i miss you.
why have you gone away??
i miss you more and more each day.
i miss your smile.
i miss your rants.
i miss everything about you.
i don't just miss the good things.
i also miss the bad.
i miss everything we shared.
everything we had.
i miss the way you would yell.
i miss the way you would kick.
i miss the way you would hit.
i miss the way you would rant and rave.
i miss you.
i miss you so much it makes me want to cry.
i miss you so much that i don't want to hear the word goodbye.
i know we're still friends.
we talk,
and laugh,
and hang out.
but it wasn't like it used to be.
way back when, it used to be easy.
now i have to decide if i should tell you things.
instead of just knowing i could trust you not to tell a soul.
now i have to deal with awkward silences.
instead of laughing and talking drowning out the nothingness.
i miss you.
i know you're not gone.
i know i can see you.
i can hear you.
i know you're here.
but you're not here.
the NEW you is here.
you've changed, my friend.
more than you probably realize.
you used to wait for me to catch up.
now you just keep walking.
you used to keep my secrets.
now i'm afraid you won't keep that promise.
i miss you.
i miss the real you.
i miss the old you.
i don't like the new you.
the new you is someone i can't trust.
the new you is someone i can't stand.
i know people change.
but this change shouldn't have happened.
it was a mistake.
a ripple in the fabric of fate.
it wasn't supposed to happen.
when did it ever say in the book of life, that you had to change??
it didn't.
so it must be a mistake.
i miss you.
i miss the real you.
i miss the old you.
i miss the bestest, most caring and loving, person.

i miss YOU . . . .

What is Trust?



Trust is both and emotional and logical act. Emotionally, it is where you expose your vulnerabilities to people, but believing they will not take advantage of your openness. Logically, it is where you have assessed the probabilities of gain and loss, calculating expected utility based on hard performance data, and concluded that the person in question will behave in a predictable manner. In practice, trust is a bit of both. I trust you because I have experienced your trustworthiness and because I have faith in human nature.


We feel trust. Emotions associated with trust include companionship, friendship, love, agreement, relaxation, comfort.

There are a number of different ways we can define trust. Here are the dimensions of trust and consequent definitions.
Predictability

It is a normal part of the human condition to be constantly forecasting ahead. We build internal models of the world based both on our experiences and what others tell us, and then use these to guess what will happen next. This allows us to spot and prepare for threats and also make plans to achieve our longer-term goals.

The greatest unpredictability is at 50%; a reliable enemy can be preferable to an unpredictable friend, as at least we know where we are with them.

Definition 1: Trust means being able to predict what other people will do and what situations will occur. If we can surround ourselves with people we trust, then we can create a safe present and an even better future.

Value exchange

Most of what we do with other people is based around exchange, which is the basis for all businesses as well as simple relationships. At its simplest, it is exchange of goods. I will swap you two sheep for one cow. It is easy to calculate the value in such material bargaining. Things get more complex when less tangible forces come into play. A parent exchanges attention for love. A company exchanges not only pay but good working conditions for the intellectual and manual efforts of its workforce.

Value exchange works because we each value things differently. If I have a whole flock of sheep but no milk, then I can do business with a person who has a herd of cows but no clothes. This principle of reciprocity is what binds societies together.

Trust in value exchange occurs when we do not know fully whether what we are receiving is what we expect. When we buy a car, don’t want to be sold a ringer which the seller knows is faulty. When I get advice in business, I want it to be based on facts, not wild opinions.

Definition 2: Trust means making an exchange with someone when you do not have full knowledge about them, their intent and the things they are offering to you.

Delayed reciprocity

Exchange is not just about an immediate swapping of cows and sheep or hugs and kisses. What makes companies and societies really work is that something is given now, but the return is paid back some time in the future. The advantage of this is that we can create a more flexible environment, where you can get what you need when you need it, rather than having to save up for it.

Trust now becomes particularly important, because otherwise we are giving something for nothing. The delay we have placed in the reciprocal arrangement adds a high level of uncertainty which we need to mitigate through trust.

What is often called the ‘golden rule’ is a simple formula for creating trust. ‘Do unto others as you would have them do unto you.’ It sets up the dynamic for my giving you something now with the hope of getting back some unspecified thing in the indeterminate future.

Definition 3: Trust means giving something now with an expectation that it will be repaid, possibly in some unspecified way at some unspecified time in the future.

Exposed vulnerabilities

When we trust other people, we may not only be giving them something in hope of getting something else back in the future, we may also be exposing ourselves in a way that they can take advantage of our vulnerabilities. If I buy a car from you and I do not know a good price, you can lie to me so you get a better bargain. If I tell you in confidence about the problems I am having with work, you could use this to further your own career at my expense.

Although the threat of retribution or projected feelings of guilt can counteract your temptation to abuse my exposed vulnerabilities, if you succumb I still get hurt and may still end up with the shorter stick. For our transaction to complete successfully, I must be able to trust that such agonies will not come to pass.

Definition 4: Trust means enabling other people to take advantage of your vulnerabilities—but expecting that they will not do this.

So what?

So learn about trust, how it works and how to build it. If you do it well, other people will give you the earth. If you betray them, they will hunt you to the ends of the earth.
