Arrival of water|Origin of water|Asteroids|Supernova

So when we look at the sea if had a thought of from where the hell this all came ?Sets see


Supernova: 

Basically water is a h20 molecule which is form by combining 2 hydrogen atoms and one oxygen atoms ,so this means that there can be a chance of formation of water in space too,but for that we need a lot more energy .Let me put in a scale for 2 hydrogen to combined and form helium we need a temperature of 10000k,and for 2 helium atoms to combine we just need 1 million k.

This means that this combining gonna just takes place in stars which are 1000 times bigger than our stars and at supernova these release oxygen which then combine with hydrogen to form water.


Our solar system was created from a supernova and scientist predicted that we get water from that but that time since earth was hot planet ,most of them roughly 70% vapor and remaining 15% just destabilized and split as hydrogen and oxygen and get trap under the crust.remaining gets trap under the smoke layers which later reforms as atmosphere and return to earth as rain for thousands of years.


Asteroids:




Another source is that from asteroids carrying ice caps. Realize this possibility because in present time we have two forms of water they are H2O and D2O , in that D2O
is term as heavy water
generally can't form under earths conditions so this means they came from outer space , they say that nearly 30% of water came from this source. you had a questions how come a asteroid have so much water.


Let me tell you a fact is that in 2004 scientist discover a asteroid ice caps and they hit it with a space probe for a 4 mile wide ,shocking tging is that it release 280000 tons water.

and that time like this nearly 400 asteroids hit earth every minute because of Jupiter's help(at that time Jupiter was also to earth and many asteroids came to earth path because of Jupiter gravity)

What is a black hole?



Even you are not a cosmology student you should have heard about black hole,previous year we got a image of it to.So what are they?How we find them?How do they actually look like?Lets discuss first lets come to the origin, they are formed by explosion of a star called as super nova when its core become unstable.



So you have a doubt that even our sun is a star this means that our sun will also become a black hole at its last stage.But the thing is that for a star to become a black hole should have a mass 20 times that of our sun.

Even though they have such mass they should have a core mass size 1.4 times of the sun after supernova explosion else there will become a neutron star.

So this is how black hole forms ,now lets see how to they look like




This image is a theorized image of Einstein
 relativity theory ,in this the outer circle is termed as event horizon and if something cross this region will be sucked by the black hole's singularity.

So what is a singularity?

It is the point where all the mass a compress to a single point .This means that volume will become zero

We know that d=m/v, then density becomes infinity.

This makes a black hole have extreme gravitational force so that even light can't escape from it
One fun fact :

 Consider that your friend crosses the event horizon and you see him from a distance telescope. at this time your friend will be sucked into pieces but you see him just 
staying in event horizon .

This is because since the black hole bend space time extremely . the time around will be slow then yours and the radio waves from him will take years to reach you.

So now see how can we take a picture of it

As i said that even light can't able to escape from it so how come scientist were able to take a picture of it.

There are two ways

1  When a star get suck or change in its speed due to black holes immense space time bending


2 .Next is that recording the radio waves  from the gases which are located at its event horizon.
 This was the method used by scientist to get a image of a black hole on April 10 2018 which is located 55 million light years from us.

The detail of how they capture will be explained tomorrow .stay tuned
