Hello boys and girls.
Roz is back..
I came back here with another interesting topic. My second topic is about Time Travel.
First of all, have you ever watch movie like Back to The Future movie trilogy like 1985,1989, or 1990.
Or like Harry Potter and The Prisoner of Azkaban.
Or probably you watched Terminators Movies
If you are big fan of TV show, you probably will cross few name of TV show such as Heroes and Supernatural
Have you ever wondered that you can travel back in time, to undo things that probably you regret or things you want to change. Or you want to travel to the future, to see what our world would be like? The idea is insane but according to our physics and scientist, that is not possible.
What is time travel? Time travel is an ability or concept that make things or human travel from one point of time to another point of time which is backward point of time (past time) or forward point of time (future time)
The element of time travel has been mentioned a lot of times, even in our own Al-Quran also mentioned about time travel.
Have you heard the story about a group of men that slept in the cave for 309 years. That one of the story that could told us about there is existence element of time travel. There's also mention about time variation which is 1 day of Allah s.w.t is equal to 1000 years of human kind.
The thing is that when time move slower or faster (means not at the constant rate like we used to have right now which is 60 seconds per minutes), this element could make the time travel possible. Famous theoretical physicist, Albert Einstein agreed with this theory.
He believe an idea that there should be a places when the time slows down and others when time speeds up. He was absolutely right and the proof is right above our heads. Up in space.
In every single smartphone in this planet, there is one feature that helps human kind to find out their current position or discover the path to their destination. That feature is GPS which is stand for Global Positioning System. In order to make GPS work, every device that make the connection have to find out or work together with satellites that orbit around the earth.
However, to make this possible, the scientist has discovered that time at space record differently with time on earth. Thus, they have to correct the time synchronize to follow the time on earth in order to make GPS works. The system has to correct the drift, otherwise this tiny little difference would make the whole GPS system collapse, and causing every GPS device on earth to go out from it's original coordinate by six mile per day.
Can you imagine the mayhem or disaster it could be? Probably for those hundreds million of people that rely so much on GPS, they will find them self at different place, from the place that it should be. Every minutes, humans, or organization like government, company, weather forecast, or even military rely on the GPS system.
The second issue is that how time at space record differently compared to the time on earth? Again, Albert Einstein said matter drags on time and it slow down time like the slow part of the river flow. The heaviest the object, the more it drags on time.
Example, if we stay very close to the gravity point which is the nearest gravity point - the earth, our time would be much slower compared to the satellite that orbit around earth because the position of satellite far away from center gravity earth.
Even though human can't time travel just yet, there's still fun to think what would happen if we could, and there are number of ideas that we have to follow if we can time travel.
First idea
There is flexible timeline that could be change or altered at will.
Example, let say in front of myself, there is one big chocolate. The taste of chocolate is so outrageous delicious until i decided to go back in time, eat the chocolate again before my past version able to do. However my decision to travel back in time is based on my ability of eating the chocolate again at the first place. So i travel back in time, eat the chocolate again before my past version able to do, i change the course of history and create the paradox.
The paradox my friend, is something that not suppose to be happen.
Example, if i travel back in time 50 years from now, i go find my own grandfather and shoot or kill him. If my grandfather died, thus my dad will not be born and i would not be exist, make the big question rise in time travel theory - how could i able to travel back in time at the first place.
Second idea
There is single fixed timeline that couldn't be change or altered at will
Example, when i reached home, surprisingly there is a bunch of chocolate in front me. I decided to eat all of it, and when time i finish ate it, i make my own chocolate and i become so confuse as the chocolate that i made are identical to chocolate that i found once i got home.
So i travel back in time, put the chocolate back at the place that i found at the first place and let my past version enjoy it.
Although the time travel is involved, the timeline compute by itself or doesn't change, and there is no paradox.
How to time travel? Our physics and scientist created a lots of theory on how to time travel but i will touch only two ways.
First idea.
We have to reach the speed of lights in order to make the time travel possible. Once we reached speed of light which is 300000 km/h, our time will be much slower compared to other people that doesn't reach the speed of light and if we able to put our position in an element which is time is not at constant rate of speed, we actually open the possibility of moving forward to backward through time.
Second idea.
We have to travel in time through the wormhole. Thanks to teech, the wormhole also known as Einstein-Rosen bridge is the theoretical passage though time and space where it could create shortcut for time traveler to go back in time when the original time the traveler come from.
The idea is that the world that we live in, space and time meet and link together called as space time and we take our 3D universe represent by any 2D of paper, and the we bend our universe by creating a 4 dimensional or 4D by pressing these two different end point of paper which is represent space and time meet, and the space when these two different point meet is a wormhole.
But it is still allowed by the law of physics that we could time travel. Time travel is not possible but improper-able.
That's all for my second test or topic. I really hope that you enjoy this topic and know a little bit infomation about time travel.
PS:/ Here my favorite TV Show character that possessed the ability of time travel.
Both name Hiro Nakamura and Peter Petrelli. The first picture, which is aired as Episode 5 Season 1 where Future Hiro Nakamura traveled back 5 years from the future and ask Peter Petrelli to save the cheerleader. This is the moment of one crucial point of time means that you change something important, it will change everything.
Future Hiro Nakamura studied deeply about time travel consequences and he decided to travel at this point of time, because he know this is the point where everything in the future could be altered or be change. By telling Peter to save the cheerleader, he actually change the timeline and the future that he been through will not be happen and thus change the history.
This is the power of time travel where you can change your history, although it not been proved yet as a fact but in science fiction, it's open the possibility what the cause of time travel could do.
If u watch all movies and tv show that i mentioned above, then you will understand a bit more about time travel.
That's all, thanks for your time for reading my blog. Really appreciate it.
