29 Scientific Observations That Will Blow Your Mind!

-

We cannot even start to grasp the whole deal about our endless universe and the endless possibilities. Most of this ends up in sci-fi movies. These movies used to follow the lead of science and now science is following the lead of sci-fi movies and scientists are trying to figure out if the things we see in such movies are possible. 

Here, we are going to talk about time travel, the Grandfather Paradox, three possible solutions to this paradox and black holes and we summarized 29 interesting and unique facts about space and universe!

1. The fastest spacecraft we have ever produced in the SPP, which will be launched in 2018. Its maximum speed is 124 miles per second, while the speed of light is 186,411 miles per second.

2. We have just been able to reach the 0,067% (not even 1%) of the speed of life. Hence, we don't have the required technology to travel to future.

3. How about traveling to past? According to quantum physics, yes, but there are several problems.

4. Let us remind you of this. Our universe is four dimensional, not three. This means that there is a space and time continuum.

5. The fact that space and time aren't separate entities brings us to an interesting result. The difference between the past, present, and future is just an illusion.

6. Which means that the past, present, and future always exist, and the universe isn't material, but has a holographic structure.

7. What we call 'time' is actually a composition of the "moments" in this virtual structure.

8. Imagine that the 'moments' since your birth up to now, when you are reading this, and from now, till your death are just photographs and are lined one after another.

9. And similarly, also imagine that somehow, everybody is in the same 'moment' slice.

10. In the previous 'moment frame' I was writing, you were reading, and someone else was having a tea or watching the TV. However, everybody was in the same 'moment.'

11. Except the people who are moving. Time is affected by movement.

12. Picture this: there is a person in the space and we are in the same 'moment frame' as we are. If that person starts walking while we are standing still; we no longer share the same 'moment frame.'

13. As that person is walking, the time will pass slower for them and when they look at us from their 'moment frame,' they might see the us from 40 years ago.

14. How do we go back to a moment in the past? There are various theories about this and the most famous one is 'wormholes'.

15. It is very difficult to pass through the wormholes, whose existence is not proven yet. There is something that blocks travelling to past: Entropy.

16. I am not going to go into the details of the other theories, but I will talk about the consequences. Let's start with black holes.

17. According to the theory, right at the core of black holes, there is a fraction in time-space continuum. If we enter through this point, we might come out from somewhere else in space.

18. Just look going through tunnels instead of crossing the whole mountain. But the problem starts after you come out of the tunnel.

19. Let's say that we pass through the tunnel (wormhole) and travel to past and we kill our grandfather, who is still a child.

20. Given that our grandfather is that, our dad and we would never be born; but we are there and we have just committed a murder. How about that? (Grandfather Paradox)

21. There are three solutions offered for this paradox: according to the first one, we go to a parallel universe that has nothing to do with anything that has happened once we kill our grandfather.

22. From that point on, the universe that we started time travelling in and the universe we end up in are completely different (Theory of Parallel Universes) and the paradox is solved.

23. And the second suggestion comes from Hawking. If the cause and effect relationship is compromised, weird things will come into play in the Earth and this event will be hindered.

24. And the last theory argues that you couldn't kill your grandfather even if you wanted to. The gun wouldn't work or you would never see your grandfather, etc.

25. Let's assume that the paradox is somehow resolved; and we have already concluded that according to physics, it is possible to go back in time; but then why is it that we don't observe this in our daily lives.

26. For example, how come we don't witness that a broken glass goes back to the way it was before, and that the water that spilled from glass going back in the glass?

27. We perceive time as the following: it moves only forward, in one way. The days go by, our childhood is in the past and we are getting old.

28. And this isn't only specific to humans. It applies to both animate and inanimate entities. Fruits decay, our clothes become older, and the world is becoming more polluted.

29. Everything goes from a state of order, to a state of disorder and chaos. Nothing stays the same: not us, not the universe.
