5 Amazing Facts About Astrophysics That You Must Know
Hello Guys welcome to our very first post that is 5 very interesting facts about astrophysics that you must know and once you get to know this u will definitely go to your friends to show off your knowledge among them so without wasting time let's start.................
1-The light photons are not really 8 minutes old which come from Sun:-
Well we all know that it took almost 8 minutes for a photon to travel from sun to reach the earth and it is also true but its journey inside the core of sun is much different that the outer space. It might take more than 1000 years for a photon to travel from its core to the outer surface. Pretty large period of time, isn't it. Well the reason behind this is the density of its core, it is almost 150 times greater than the density of water and the rest you all know.
2-Actually water you are drinking can never be fresh. Still Hygienic?......:-
We always try to drink fresh water to show ourself as a hygienic person but do you know every drop of water we are drinking is as old as our solar system. Well each drop of water which exist on earth is 4.6 billion years old. This is because water which exist on earth is the residue in our solar system after the formation of earth. Hence next time while drinking water remenber that it is 4.6 billion year old drop in your glass
3- You are 99.999999% free space... Do you really exist:-
Well You might think that You are fat , heavy or whatever , but actually you aren't .Also chemistry had told you 70 % of your body is water whereas on contradiction biology says that 50% of your body is blood. But they are all wrong. According to physics 99.99999% of your body is free space. This is because there is too much free space inside a atom you are made of . Still confused let me give u example:- if nucleus of atom was a size of peanut then size of atom would be of a basketball ground. Be happy you aren't fat.
4-You cannot touch anything.....and i am not Lying:-
What will happen if i will say that you are not actually holding Your I phone(or Nokia 1100) in which you are seeing this phone? Well you will definitely call me a mad bonze. But actually Physics says that we cannot touch anything in this word this is because of the repulsive force of electrons. Now if you think that what is that feeling of touch so it is basic physics and fundamental force of nature.......any Guess.?.....Electromagnetic force ! So remember , Your dreams Should be High As you can Fly........
5-Voyager 1 can never escape our Milky Way Galaxy:-
If you are a true astrophysics fan then you must have listened about Voyager 1. if you haven't then voyager 1 is only man made object that had leave our solar system. but do you know that in its entire lifetime it could not be able to reach outside our milky way galaxy. If you thik it might be slow then wait a min its speed is ..........62,140 km/h.....so now you can know that how vast is our galaxy......................
