Some interesting facts about our universe ;
- We do not exactly know how Milky way looks if viewed from outside.
Yes, you read that right. We just know that it’s a spiral galaxy and we cannot send a probe far enough to capture the entire galaxy. All the images you have seen are just artistic works created by looking at other spiral galaxies.
Below is a false image of our Milky way.
2.
The universe is like a giant cosmic web with galaxies in filaments and empty space in between known as voids. It is hypothesized that our galaxy may be in one of these voids as there are not many galaxies surrounding us.
Every small light in the picture is one whole galaxy.
3.
All the pictures of exoplanets we have seen are false too. All we know about these exoplanets is shown in the images below.
This is the dip in the light of the star the exoplanet is orbiting when it passes in front of the star. We observe it through telescopes.
Correction - There are some exoplanets whose direct images have been taken. But they are nowhere near to the images we see floating on internet. One such false image has been shown below.
In reality, they are more like this
The red spot is the planet and white spot in the middle is a brown dwarf also known as failed star.
4.
The distance between cosmic structures is so vast that it is irrelevant to depict them on paper with real proportional calculations as structures would be too small to see with naked eyes.
So all the pictures we have seen with all the planets in the solar system in one picture is by use of improper distance. In a real sense, the Earth wouldn’t even be visible if we were to map the entire solar system on one piece of paper maintaining the proportions of distance between every structure.
5.
Moon revolves around Earth, Earth revolves around sun and sun revolves around the center of Milky way.
6. Space itself can expand faster than light. This has already been happening.
7.
Most of the space inside atoms is empty space. If you think of the atom as big as a football field then nucleus would be size of a tennis ball and electrons would be at the edge of the field. If you do not leave any space between fundamental particles, all of humanity can fit in a sugar cube crystal.
8.
Quantum entanglement is a phenomenon where effects take place instantly over large distances (even faster than light). But we do not know how to use it to pass information.
9.
Space between stars in a galaxy is huge. It is so big that when Milky way merges with Andromeda in about 4 Billion years, there would hardly be any collisions between stars and mind you each galaxy has billions of them.
10. As
Milky way and Andromeda are going to merge in 4 billion years, our night sky view will change. Here’s what it will look like in about 2 billion years.
Hope life have been treating you good!
