Important Questions

"And why doesn't glue stick to the inside of the bottle?" Mikey asked while he looked at the bottle he was holding. He turned it over and watched the glue slide to the lid-side. Don sighed and lowered his screwdriver. "Because most glues need air in order to set," he replied, trying to sound gentle. It was probably the fiftiest question Mike asked since he entered his lab today, and Don was beginning to get slightly annoyed. He loved his brother to the fullest, but sometimes he could be a real pain in the -

"But what happens before that? How do they get it in the bottle?" Mikey watched mesmerized at the sticky goo, which now was flowing back to the bottom.

"With a machine," Don answered curtly and he raised his screwdriver again. With a short humm, Mike accepted the answer and he put the bottle back down on the desk. The then turned his attention to Don. "Whatcha makin'?"

This time Don didn't put the effort in putting his tool down. "I'm fixing this lamp holder so we should have light in the bathroom again."

"Was it broken then?"

"Yeah… Didn't you realize it was dark in the bathroom this morning?" He put down the screwdriver and grabbed a loose wire. When he heard nothing from his brother, he looked up, only to find a rather difficult look on his face. He sighed again, waiting for the next question.

"There is a speed of light, right?" Mikey began.

"Yes," Don said a little bored, knowing exactly what question would follow. Mike nodded. "So what's the speed of the dark then?" He cocked his head and looked at Don, who was trying to secure the tiny wire, which was kinda difficult with his large fingers. "Darkness moves at exactly the same speed as light. Actually, the dark is not a thing per se. In other words... It doesn't exist itself. It just indicates the shortage of light," he explained trying to be understandable, which failed.

"What?" Mike asked confused. Don bit his lip, knowing he went too far, so he tried something else. "If we talk about the speed of matters, darkness is the result of what you get when the light stops coming, right?"

Mikey swallowed, thinking the answer over. "Uh-uh," he concluded, still not fully understanding. Don smiled. "Therefore the dark is as fast as light, because they have to neutralize each other in a very short amount of time." He grabbed his screwdriver again and secured the wire with a tiny screw. "The dark has to come immediately when the light ends, and vice versa, so light and dark are just as fast. Got it?"

"Yeah! I guess so!" Mike smiled happily, then he got serious again. "But what if you are in a vehicle and, hypothetically speaking, travelling at the speed of light.. What will happen when you turn on your headlights?"

Don stopped in his tracks, not expecting this question. A little perplexed he dropped his hands to his desk and looked at Mikey, who looked back expectantly. "Well… I…" Don began, not really knowing an answer right away. "I think that not much would happen. Just the same way you turn on the lights if you were not moving." Don leaned back in his chair and rubbed his chin with his hand. Mikey nodded and opened his mouth to comment, but was cut off by Don. "The theory of relativity stated that the laws of physics are the same in all inertial reference frames. It also means that the speed of light in vacuum is the same to all observers in the same inertial frame. If one is not accelerating, so no force is acting on the observer, although moving at a constant speed…"

Mike tried to come in between his brother's monologue, but he knew it was no use. He started to smile, knowing he finally asked a question Don had to think about, which he considered a personal victory. Silently he stood up and walked out of the lab, leaving Don and his personal rambling alone.

Yeah, I borrowed some questions of the internet. Please, don't hurt me!

But I really hope you liked it! If so, please leave a review! I love to read what you think about my stories.
