Last Wednesday was no ordinary. The event horizon team were able to engineer the first picture of a black hole. Since over a hundred 100 years, this has only been imaginary and theoretical. Not any more though.
Journey of a Soyuz spacecraft
Space exploration has always been a hallmark of national accomplishment. During the 1950 – 1980, USA and USSR were head to head in space exploration. Yuri Gagarin from Soviet Russia became the first human to be in space in as early as 1961. Since then, We have come a long way not just in terms of exploration but also in terms of technology sophistication.
Origins of Gold
In my previous article “How it all started…”, I expressed on how a star fuse elements of our periodic table in its core.
Also, how star cannot fuse iron and it leads to a big supernova explosion.
The question arises, If this is true how do we find elements in periodic table which are higher then Iron are produced? For e.g. Gold, Lead, Plutonium, etc.
Antimatter, What and How much can I buy for?
Some time during the creation of the universe 13.8 billion years back after the big bang, matter overpowered antimatter. During the early stage after big bang the universe was unstable. Matter and antimatter reacted and obliterated each other in big release of energy repeatedly.
Some how at that time matter won against antimatter and it survived. Since then, whatever we see on planet and around our solar system and space is all matter.
The legend of the black hole
In 1 of my previous article about beginnings of universe i explained how star fuses elements in its core. So just after supernova explosion, a star bigger then the size of the sun turns either into a neutron star or a black hole.
Where exactly are we!
Our planet earth has about 510.1 million square kilometres in surface area. We are part of the solar system with sun in the centre. Our sun is whopping 109 times diameter then the earth.
Our solar system is roughly 122 AU in diameter where each AU (Astronomical Unit) correspond to 150 million kilometres!
How it all started…
Today with help of cosmic background radiation and other methods, we are able to trace back the sequence of events, which led to the creation of earth.
13.8 billion years ago, a catalytic event took place. We have named it “Big bang”. We are not certain what exactly caused this event. There are several theories but cannot be conclusively established.
