Everybody would love that, "time travel", going to the future to catch another episode of your favorite tv show or to the past, reliving your best memories.
The question is how do I time travel? Easy, by running very fast, how fast? like Gatling? Usain bolt? No like FLASH⚡️⚡️, that sucks, because the fastest man "bolt" clocked 22.8 miles per hour, that's like my grand mum driving her beetle through the highway, still pretty impressive for a human. So how fast is the Flash? 🤓(nerd alert❗️) 700 miles per hour as recorded in "city heroes" episode one were he had to counter the weather wizard "tornado". That's like 15 thousand times the speed of the fastest man on earth.
Well here at meta_science we are only concerned on how he "The Flash" does it, not how you are going to do it😎. So this is what we think.
🤓(nerd alert❗️): according to Einstein, time is relative, his theory of relativity says "time slows down or speed up depending on how fast you move relative to something else. Lets simplify 🤓(nerd alert❗️) speed is a function of time and distance, speed is directly proportional to distance and indirectly proportional to time. So the faster you go the more distance you cover but also the faster you go the more you slow time.
So your saying the faster I go the slower I observe time, it doesn't sound like time travel to me🤔, I get, follow me closely so we could tell how Barry Allen does it.
🤓(nerd alert❗️) you probably have heard about the "The Speed Force" the flash tapping into the speed force and all that, we will get to that but first, baby steps, "Timeline" you've also heard about that too. Timeline is a concept that differentiates realities, it separates 2 pm from 3 pm, yesterday from today, last week from this week, last year from this year, last decade from this decade, and what's the different between yesterday and today 🤓(nerd alert❗️) 24 hours, so it's safe to say we measure timeline with time. A Timeline is it own reality, it could be in seconds, minutes, hours, days or weeks, even a year.
Stick we me we almost there😎
Think of a Timeline as radio station with a unique frequency, to connect with a particular radio station you need to adjust your radio to its frequency, the frequency of a Timeline is speed, so you need to attain a particular speed in order to access a Timeline.
Lets be practical with assumptions🙂
You noticed the blades on a helicopter, once the pilot kicks the engine into life and the blades that turning, haaa! Did you observed, the faster the blade turn the less visible it becomes, it gets to a speed that your naked eyes can not make out the blades anymore, let me scare you, (whispers)"those blades just time travelled," from your timeline to another, remember a Timeline is measured by time and accessed by speed, according to Einstein time slows down or speed up according to how fast you move in relation to something, the blades sped up, slow down time, accessed another Timeline in relation to you that move in a constant speed and still present at your own Timeline.
Now back to the Flash ⚡️⚡️ remember the Speed Force, whenever the Flash time travel he uses the Speed Force, the Speed Force gives him the ability run at different higher speeds, thus, access to different Timeline, the past, future, an hour from the present you name it. The speed force is like a radio, giving the Flash the option of different frequency(speed) to access different radio stations(Timelines)
So when next your planning a time travel like Barry Allen.....get your running boots right😉
