Ayyy I want to nerd out too!

1. Let's talk about infinity.
Firstly, infinity is not a number but a sign, so it can't be compared to the numbers.
Secondly, infinity doesn't exist. Why? Let's take a simple question: What's a sum of all Integer numbers? Obviously, it's 0. Because each natural number has it's negative (inverse) number and their sum will be equal zero. But, if we'll add all positive numbers first, then all negative numbers, we'll get positive and negative infinity (since the amount of natural numbers is infinite). And the sum of those infinities will be an infinity, however. Why? If we'll deduct the amount of all natural numbers from the sum of all natural numbers we'll get infinity (actually, the max natural number deducted from the sum of all natural numbers). So, infinity minus infinity equals infinity. But we're totally sure that the sum of all integer numbers is 0 (see proof above). This leads to a contradiction, which proves that infinity doesn't exist.
2. Space. What it is, actually? If we talk about stars, planets, galaxies, etc, then we call it space. If we talk about certain area, we also call it space (e.g. space between two things). First space is surrounded by our Universe's border, which grows faster than (or the same as) the speed of light. So nothing can actually get outside of the Universe. Second space is where our Universe is located. It's actually made of nothing, and the Universe is the space where time exists. Well, agree that nothing can be in a place where time doesn't exist; how it would be there then?
3. How the Universe actually started? Big Bang theory! Yes, the one which states that Universe existed as a substance with max density and temperature (aka singularity). Then it started to grow (and it still grows). It also states that Universe started its existance with time. Unfortunately, nobody has proven yet what had happened before time appeared.

Okay, I think that's enough xD
Good luck :3

I think about space sometimes.
But not like, space space.
Like the space where nothing is. The stillness in the air.

The endless space of silence.
 
This is slightly off topic (Or more of just our own Solar System) but what does everyone think of the Hypothesis of the 9th Planet of our Solar System. Here is a link to the Article Here. Or for those to lazy to read (TLDR) here is an image of its theoretical Orbit.

Many theories state that Planet X is actually a star and the sun has a twin. After all, 60% of the stars in the universe orbit another star; why should the sun be an exception? (Might have said something about this in the article, but I didn't read it)
Why were there dinosaur extinctions once every 65 million years or so? Well, when planet/star X passes close by the sun, it disturbs the asteroids and comets in the Kuiper Belt with its gravity, and one rocky body gets slingshotted to Earth. X must have a looooooong orbit.
I'd recommend the book A Brief History of Time by Stephen Hawking to any of you wanting to learn more about space, time, and wibbly-wobbly timey-wimey things. (Not really that last one, but whatever.) It's well-written and deep. I read it myself awhile ago, and being the nerd I am, I thoroughly enjoyed it. It's a difficult book to read for some, but try it out if you're nerdy.
Also, hey look Pluto! My home! <3

I was reading that theory as well however they are not going as far as saying what type of Celestial Body, they simply suggest it's similar in size as too Neptune. They Suggest it's orbit is in between 300 au and 1200 au (Astronomical Unit is approximately the distance between earth and the sun which is not static(However it is defined as 149,597,870,700 Km)) and takes Approx. 15,000 years for a full circuit. Here is a picture of NASA Voyager1 And Voyager 2 Which are both around 122 au away (Don't Quote me on that) for a reference

Hehe Doctor who, ill have a look, could be quite interesting. I really like reading about black holes though if i am honest, they are so Awesome!

DID SOMEONE SAY SPACE
*clears throat*
Okay. Time to nerd out.
Here's some food for thought: space does not begin or end anywhere, right? It's infinite. The point of infinity is to be endless. But what if I told you that some infinities are longer than others?
There is an endless amount of whole, positive numbers. There is also an endless amount of whole numbers, both positive and negative. But we can agree that there are more whole numbers than just positive whole numbers, right? Both amounts, though, are endless.
It's difficult to comprehend. Infinity in math is intriguing. Infinity divided by 6 is infinity, infinity divided by 1,000,000 is infinity...
But anyway, spacey things. Right. Leeeetttt's stop doing math and drop some cool space facts because you boring people don't like math :)
  • Did you know that at the center of a black hole is said to be something called a singularity? A singularity is literally a single point. It's impossible to get any smaller.
  • Also, black holes are so dense and have so much gravity that even light, the fastest-traveling thing in the universe, cannot escape their pull. This is why they appear black: darkness in the sky is a lack of light.
  • The iron in your frying pan once made a star explode! See, stars, when they run out of fuel, collapse in on themselves because of their own gravity, exploding in a fantastic event known as a supernova. Why do they run out of fuel? Well, stars fuse atoms of hydrogen to create energy, and those newly-fused atoms continue fusing into heavier and heavier elements. Eventually, the element of iron forms in the star's core, which absorbs any energy created by fusing. This is when the star doesn't have enough energy to resist its own gravity, and boom! Supernova! (I totally blew your mind with that one. Ha. Ha. Ha... ok I'll stop)
  • Gravity is by far the weakest of the four forces in the universe. If the weak force, a very small and weak force as implied by its name, were the size of a bone, gravity would be the size of a small fly. Gravity is smol :D
  • It takes nearly 3 years for the light from the nearest star to Earth (other than the sun) to reach our eyes. Light travels roughly 6 trillion (6,000,000,000,000) miles (or 10 trillion km) in a year. Think about that for a second. And it would take the light from the edge of the universe 46.6 billion years!
ok I'll stop blowing your minds now (if any of you even understood that because I'm too nerdy)

I've readed Steven Hawkins and Stephen hawking a George books. It is very recommended for you guys
 
I just googled space. And I got some weird puppet from Cookie Monster or Elmo's closet... WHAT IS THIS
