Speed Of Light

 The speed of light, usually denoted by c, is a physical constant important in many areas of physics.It Is Maximum Speed At Which Energy ,Matter Can Travel .Its the Fundamental Constant In Physics.
As We All Know That Light travels At a Speed Of 3*10⁸ meters Per second .Which Would Be Precisely Around 299,792.46 In a Second Or 1,079252956 Km Per Hour .
So Far We Didn't Even Made Any Significant Close To The Speed Of Light.Nothing can go faster than the speed of light. As for matter, it can never reach the speed of light,To Reach The Speed Of Light a Space Craft Should Have Infinite Supply Of Energy Or Zero Mass .

Einstein theory of relativity address that question quite well. Mass will increase exponentially so that the velocity will reduce, until mass becomes an infinite value when the velocity reach light speed.
Both Are Impossible In reality.Photos And Electrons which Have Infinitely Small Mass Move At Fraction Of Light Speed.And even if the physicists tell you it can't be done.

Space Travel Always Been a Dream Of Astronomers How Ever It would Take A Life Long to Travel To Pluto And Even More With Present Fastest moving Space Crafts.Travelling at light Speed Or Even Close To Or At least the Fraction of Light Speed is Fictitious Thing.
Hope That a Day May Come In Future Time Travel is Possible Just like In Star Trek.
As Einstein famously told people that it was impossible to split the atom and that you would always need to put more energy in than you would get out of it. Well now look where we are in the nuclear age! Nothing is impossible In This World If We Give A Try !!

Scientists map 'nature's big bang' for first time

Cells are the building blocks of life. Cells are the smallest fundamental units of an organism from microbes to high level living beings humans. Millions of Cells make up an organ ,which form multi cellular organism. But the scientists are till now unable to interpret how building blocks are found and how they paved a way for life.a notable discovery been made which could change the face of cellular biology by ireland scientists.
Researchers led by a team from ireland  said for the first time they have mapped the nature's big bang when two cells fused into one living organism. Scientists claim they had found how they fused to form multi cellular organism. They called this as "nature's bigbang",evolution of life.

As big bang suggests the evolution of universe. A team of scientists led by irish university professor Dr McInerney  With cambridge university's james cotton have been researching on cells from 10 years . According to them single cell bacteria , single cell arkian fused to give birth to yeast . From which insects ,plants animals have evoluted.

Dr McInerney said: "Essentially, you had an organism, like the Minotaur in ancient Greece, and this, in biological terms is what we hypothesised was the common ancestor of all eukaryotic life.

"Because humans are eukaryotes, we were, in essence, trying to trace the deepest human ancestor." Dr McInerney collaborated with Dr James Cotton at the Sanger Institute in Cambridge to make the discovery, which is published in the journal Proceedings of the National Academy of Sciences.
