Why trees, mosses, and algae are green??

Why trees, mosses,  even algae are green?

Woow. Thats a great question.
First,  they have chlorophyll on their sell. And, second why chlorophyll is green??

Ok, then. Chlorophyll is a pigmen that caught a photon from sunlight. You know that when you put the sunlight on prism you'll get a rainbow color from the sunlight. So, chlorophyll only absorb a red and blue (violet) rays that rays are needed in photosynthesis reaction. But the the green ray bounced back. That's why leafs, mosses, alga are green.

So, guys that's the reason why are they look green in our eyes.
So, how about the other color? Flowers, wood, or others? So, it depends on what pigmen it has.

Higgs Boson

"Higgsogenesis" Proposed to Explain Dark
Matter

Interactions of Higgs bosons and anti-Higgs in the
early universe may also have caused the observed
asymmetry between matter and antimatter
By Eugenie Samuel Reich and Nature magazine
The Higgs boson may have played a key role in
the early Universe, including the creation of
mysterious dark matter.

A key riddle in cosmology may be answered by the
2012 discovery of the Higgs boson—now a leading
contender for the 2013 Nobel Prize in Physics on
October 8.

Gambar-gambar Lubang Ozon

Lapisan Ozon di Kutub Utara Kian Menipis

Lapisan ozon di Kutub Utara yang menjadi pelindung radiasi ultraviolet telah menipis sekitar 30 persen pada musim dingin ini.

Demikian bocoran yang didapat dari Badan Cuaca PBB di Jenewa, Selasa (5/4).

Lapisan ozon yang rusak di Arktik memang tidaklah sama dengan kerusakaan ozon di Antartika yang dikenal "lubang ozon". Lubang ini terbentuk ketika sinar matahari ada di sepanjang di musim semi tiap tahunnya.
