25 Mind-Boggling Facts About The Universe That Will Make You Wonder If we Are Really Alone Here

5. There is an object in the universe which is pulling the Milky Way Galaxy and millions of other galaxies towards it at 14 million mph.

There is a cluster of galaxies called ACO 3627- previously known as Norma Cluster- that is located near the center of a large mass which is known as “The Great Attractor.” The great attractor is so large that it pulls our own Milky Way Galaxy and millions of other galaxies towards it. Many of the galaxies in the ACO 3627 galaxy cluster are slowly heading towards a collision with each other. The galaxy cluster has more than 8000 galaxies and with a total mass more than ten million billion times the mass of the Sun. (Source)

4. There are about 24 GALAXIES in the universe for every single person alive on earth.

Approximately 170 billion to 200 billion galaxies exist in the observable universe. As of July 2015, EGSY8p7 was the oldest and most distant observed galaxy with a light travel distance of 13.2 billion light-years from Earth and observed as it existed 570 million years after the Big Bang. By calculation, if we divide the total number of galaxies in the observable universe by the total number of people living on Earth, the result would state that there are 24 galaxies for every single person who is alive on Earth.

3. When you look at the Andromeda galaxy (which is 2.5 million light years away), the light you are seeing took 2.5 million years to reach you. Thus you are seeing the galaxy as it was 2.5 million years ago.

Andromeda galaxy is the closest to our Milky Way galaxy which is 2.5 million light years away. The light that enables us to see this galaxy left Andromeda galaxy 2.5 million light years before. This means that when you look at Andromeda galaxy, you are not looking at its present state, but you are looking at how the galaxy used to look 2.5 million years ago. That light left Andromeda before we had Homo Erectus on Earth. Similarly, there are galaxies out there, where aliens with powerful enough telescopes could be watching dinosaurs roaming the Earth, right now. (1, 2)


2. Look at your wrist, see the blueish veins? The blood flowing through them contains hemoglobin, a protein that has four iron atoms incorporated into its structure. Iron is only naturally produced in one place, it can only be forged in the core of dying stars.

Every time you look at your veins, remember that you are built from, and kept alive by, pieces of stardust. How? Because most of the atoms were born in the intense few minutes following the Big Bang. When the universe’s first generation of stars coalesced, they were mostly made of single electrons and protons. These stars fused their available hydrogen into helium, and were correspondingly short-lived and disintegrated into new stars while releasing elements into space. The second generation of stars formed out of the debris of the first died in supernovas distributing even more elements out into space. Iron was made in one such explosion. (Source)

1. Instead of looking up into the sky, you’re actually gazing down into the infinite cosmic abyss, with only gravity holding you to the surface of the Earth.

The size of the Cosmos is beyond ordinary human understanding. Lost somewhere between the eternity and immensity is our tiny planet, Earth. Just imagine this- you are in a spaceship called “Earth” that is driving through the infinite cosmic abyss out there that is beyond any human comprehension. And Gravity is the only thing that is holding us to Earth and also preventing us to dissolve into the never-ending universe. (Source)
