Factors to Go Back - Part 3: Cosmic Strings

Welcome back friends to TARDIS Talk!

Last time, we took a glance into a cosmic phenomena that was theoretically capable of time travel: the black hole. Today, we will be looking at one other cosmic phenomena, somewhat similar to the black hole. We will be looking at the Cosmic String.

I went into the internet again to search for information on these defects in space time and I came upon the Anderson Institute website. I found very interesting information, part of it being applying the cosmic string to an actual time machine construction.

To start off, what is the cosmic string? A cosmic string is a "string" or threadlike object throughout the universe and space. It is extremely thin, even smaller than an atom that is pushed under immense pressure. Because of this very reason, it has a massive gravitational pull to anything relatively near to it.

the white lines, cosmic strings)

The way this works in time travel is time dilation. This means that if you put two of these defects in space together, they will create a time - like curve that if traveled around a certain way, the gravity and velocity could propel you faster, slowing down time and ultimately bringing you back to the past. This brings us back to relativity, so be sure to keep that in mind. By this theory of connecting two cosmic strings, or one string to a black hole, we could be able to use them to travel in time.

These strings are all mostly theoretical and have yet to find actual legitimate evidence of it in space. Although we have yet to find actual cosmic strings to use at our disposal, scientists have discovered clumps of matter being pulled close together in space, suggesting a gravitational phenomena.

Anyway, thank you for tuning back in to TARDIS Talk. Next time, we will be exploring yet another theory in time travel: the Wormhole.

Once again, I thank you all for coming to take part in TARDIS Talk! And now, I must bid you goodbye.... for now.
