TIME TRAVEL! The Most Controversial Sci Fi Topic

Alright, because none of this has been proven true, this is all my very own scientific opinion. Time travel seems like an interesting idea. Imagine being able to go back in time and see the world unfold or travel to the far future to see the world end. Pretty awesome right? Well unfortunately, there are limitations to time travel.
So think about travelling in a car down the street, you are travelling in three different dimensions. Time, is the fourth dimension, and so there must be a way to travel faster through it right? Well there is, at least that's what scientists theorize. Everything has a length in time just like they have a length in space. Our length in time is about an average of 80 years. Where particles have an infinite length in time. So there has to be a way to travel through this fourth dimensions. Scientists have theorized that these tiny holes smaller than you can see are breaks in time and space. These are called wormholes, connecting certain points in space and time. If scientists can find a way to enlarge these holes, then time travel would be possible. Unfortunately, you would not be able to choose the destination in time you would like to go. This picture below shows that different points in space time are connected by tiny points. We have yet to find these wormholes so we can only theorize about the existence of them and unfortunately cannot create the technology to enlarge these objects.
