He who had finished thinking, then turned the direction of his body again right in front of Andi and answered him directly from his question Andi.
“That leap of time is just like a concept of running time forward or backward to a different point, in the original time or at zero and so on, similar as we move in three-dimensional space.”
Ms. Anna explained slowly while moving her hand.
“Travel time? Inside the third dimensional space?”
Andi who was still confused, because he thought of a row of a few more questions to Anna, he was happy to continue.
“Begini Andi's. In theoretical physics, the concept of time travel has been used to examine the consequences of physical theories such as special relativity, general relativity and quantum mechanics as they are in the book's title.”
Ms. Anna this time explained while pointing one finger at the book that Andi was holding. Andi's eyes followed Anna's finger, she also looked at the book she was holding. Ms. Anna continued her explanation with a relaxed and slightly serious start.
“There is no experimental evidence of time travel, nor is it understood whether current theories of physics permit time travel in any form. However, there is a theory that allows about the possibility of folding time to jump from one point to another.”
Andi who still did not understand what a blackhole was, he spoke again calmly while closing his eyes and thinking.
“Keep what is blackhole?”
“Terus blackhole is in its modern form, the concept of blackhole arises from Einstein's general theory of relativity, which predicts that if matter is sufficiently compressed, the, its gravity will become so strong that it forms a simple region of space and time from which to everything and cannot escape very strong gravity.”
“What does quantum theory have to do?”
“So, in other words utilizing from some theory a fusion of electromagnetic quantum theory and a gravity of a blackhole, we can make antigravity like a leap of time to another time.”
Andi was still confused from the explanation by Bu Anna, about what a time jump is, and what the relationship between quantum theory is the same blackhole, he while scratching towards the back of his head and smiling.
“I still don't understand anyway, Miss Anna.”
“You will definitely understand about the explanation that I gave earlier after reading the book that you hold it.”
“... Hmmmmm?”
Slowly the right hand of Anna's mother was frowned up, she looked around at the place she wanted to touch.
He touched Andi's head, then stroked Andi's hair slowly, while saying a happy tone.
“Really you are yes?”
After finishing, for some reason, Andi came back again with a cheerful face.
“Ok bu Anna, thanks for the explanation mom.”
Andi rushed to the library.
“Iya Andi's. Oh yeah, be careful on the way home. Go straight home, don't stop by a dimly lit place! Ok.”
Andi thought, there seems to be a word, from words that are not so understanding and unclear that came out of his mouth, Anna.
“Iya Ma'am. Uh, dimly-lit?”
With a short pause, Andi ignored him and quickly, he immediately brought the book he had obtained to the front of the school library cashier to make a written contract agreement.
With all due respect I want to understand and understand from what the contents of this book are, therefore with this, I pleaded with the school library to grant me a loan contract permit to borrow this book I was admiring from the library.
After Andi got permission from the school library to borrow a book. He rushed out and decided to finish borrowing books from the school library, he who did not forget to buy food for dinner later with his sister.
After arriving outside, he looked up at the sky, he felt shocked and a little panicked, suddenly the sky became pitch-black marked with the rain coming down. Andi who does not forget will bring an umbrella, because he already knew that today it will rain. She rushed over quickly while hurriedly removing her umbrella from inside the bag.
“Payung! An umbrella? The umbrella! Well Here it is.”
