"It means your future hasn't been written yet, no one's has. Your future is whatever you make it, so make it a good one." — Dr. Emmett Brown

Compared to other space themed, time travel movies, Robert Zemecki's award-winning movie, Back to the future, has been a huge legend throughout history. In the movie, they travel through time and spaces to past, future, and even alternate futures, just to learn that you are writing your own history.

But why October 21st?

But in the movie, there is one particular day they focus on October 21, Why? Well according to Business Insider, that’s when in 2015 the Chicago Cubs was predicted to win the world series. That prediction, however, is not entirely true. Although in 2015 the Chicago Cubs lost the World Series, they came back in 2016 and took home the win! (This is why Marty shouldn’t have taken the sports farmer's almanac in the first place.)

Dr. Emmet Brown, meet Doctor Who

At first, the movie seems like a typical movie, it turns out to be a sci-fi movie. However, the TV show “Doctor Who” also places a huge emphasis on time travel, only in a phone booth. Both of them are exactly the same, only with a few minor but noticeable differences.

Both franchises talk about time travel, but back to the future actually used it as part of the plot, whereas Doctor who used it as a framing device to get from point A to B. In the end, the tribology helped kicked-off the most popular British franchise in the world.

Is Time Traveling Possible?

In almost every sci-fi movie/ tv show ever shown has some form of time travel. According to NBC news, time traveling into the future is actually easier than you think. However, going back in time is a little bit more complex. In 1916, Albert Einstein came up with the “Theory of Relativity” that showed that time and space was basically connected. His theory states that time and space responds to matter by warping, expanding, and contracting.

Dr. Emmett Brown says that when time traveling, you have to be careful of what you do or else you can disrupt the space-time continuum resulting in an alternate reality of the future. Einstein’s theory of Law of Causality, which is a cause and effect basis explains Dr. Brown’s explanation further. When one event happens in our universe, it leads to another, and then another in a series of one-way string of events, without a chance going back and changing it.

Throughout history, people have made a way to the present as we know it today. If we disrupt the past, then our future could most likely be changed. As Dr. Emmett Brown said, you write your future because it has not been written yet!
