The observable universe, the universe that we can see is about 90 billion light years across, Which means that light would take about 90 billion years to reach from one point to the other. In this gigantic universe there are about 100 billion galaxies. Each galaxy contains between 100-1000 billion stars. Also we have recently understood that planets are very common .
Realistically speaking it is pointless to speak about any place in the universe other than our local group , a group consisting of our milky way galaxy and some clusters of galaxies. I say this because it is nearly impossible to travel beyond our milky way in search of extraterrestrial life as it would take billions and billions of years to reach there. So let us just focus on the milky way.

Well mathematically speaking anything can be a black hole if u can compress it to a small enough size so as to make its density so big that not even light can escape its gravity you will have a black hole. The minimum size that you would need to compress an object into to make a black hole is called as its “Schwarzschild radius.”
If you could compress the size of Mount Everest into the order of Nano meter (almost the size of a HIV virus) you would’ve a black hole. That’s ridiculously dense!!!!!

Well before you pat yourself on the back and get on a high horse let me explain why you definitely are the center of the universe yet you are not special (well maybe you are ..i don’t know who you are )
This phenomenon is what is called as the cosmological principal.
No matter where you are in the universe everything relative to you will seemingly be moving away from you and expanding at the same rate. Imagine a balloon expanding and imagine the universe ..galaxies, stars, planets you and me to be on the surface of that balloon . Now as for any spherical object there is no center on the surface you pick any point and that will act as the center…PERIOD
To make it simple take the below example the blue dot represents a 5% expansion relative to the blue dot(the past).lets assume you live on one of this dots. As soon as you choose any point on the the blue dots surface and put it on the past surface that point becomes the centre of expansion. …mind blown??

Well before you open up a new tab and fill your internet history with ‘space porn’ hear me out, I’m positive that there is no genre called space porn .. believe me I’ve checked **clears throat** for research purposes….
And there might be a very good reason why
Before we begin lets see if there were any actual attempts made by any space organizations to make 2 people do the deed in space ……well no , and for very good reasons you don’t want your genetic material floating inside a scientific vehicle ..do you?
But let’s assume you are crazy rich and you have decided to bring your fantasies of ‘banging in space’ a reality (**you sick weirdo**) .You reach your private space station. Make the lady sit ,open up a bottle of wine, turn on some good music and get into the mood. Hmmmmm….. You like that don’t you…lets just stay on track
Here comes problem no. 1 Continue reading “CAN YOU HAVE SEX IN SPACE?”
