Factors to Go Back - Part 4: The Wormhole

Welcome back time travel theorists of the internet!

Today, we will be analyzing yet another purely theoretical way of time travel: the wormhole. To start off here, we must ask, "What is the wormhole?" The wormhole is a "cut" or shortcut, yet another defect in space-time. Although purely theoretical, scientists have found it possible that they exist, however very small in size.

Exploring the inter webs once more, I found the Live Science website and found more about the wormhole than I had expected. I found that the wormhole would be able to send a ship or any object from one end of the tunnel to the other, at the speed of light... sort of. What it really would be doing is taking a shortcut, making the time and distance to travel short.

One thing that we have found in actually making wormholes is the immense amount of energy to make the wormhole turn into an actual means of time travel, rather than location travel. That, and then the stability of opening it by exotic matter. These challenges in the wormhole itself prevent any further research from being able to even control, or find a wormhole. However, theoretically, if controlled and directed in a certain way, it can be absolutely used to travel through time. Although it is theoretical as a real thing, it bounces off Einstein's theory of general relativity, so there is some hope for any existence of it.

At least one of the tunnels would have to be accelerated
through time, at a certain point, for this to be a viable
means of time travel.

So, could wormholes actually be used to travel through time if any existed at all? Could we be able to generate one? How would we control it? Many questions need to be answered to know whether THIS theory would be a valid way to time travel.

Thank you for coming back to TARDIS talk and exploring the wonder of time travel and the many possibilities! Now, I have covered all that I can cover, or everything that has been researched thoroughly, in traveling back in time. Next time, I will be explaining something that I probably should have gone over with you all at the beginning: the dangers of going back in time. For now, goodbye my friends and I will see you then!

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 box and red dots represent the universe;
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.

Factors to Go Back - Part 2: The Black Hole

Welcome back everyone, to Tardis talk! 

Now, last week we started off our backwards time travel with the theory of going faster than the speed of light. Today, we will be talking about existing cosmic phenomena within our galaxy and other galaxies: The Black Hole.

I found more information on the black hole from several websites, all addressing the same thing, that the black hole is purely theoretical. One of the sites that helped me understand a bit more was the HowStuffWorks site, once again. What I found was not extensive or vast information on the black hole, but rather just a brief introduction to what it is, since no one has really confirmed if it will really work in time travel or not. 

What HowStuffWorks talks about is what the black hole was and, in theory, what it can do.  First off, what is the black hole? A black hole is what happens when a star dies. When the star dies, the nuclear fusion reactions stop and at the same time, the star's gravity pulls in objects and compresses the core. As the core compresses, it eventually creates a supernova explosion and the aftermath is a highly compressed and massive core. This core now becomes a black hole, creating a hole in space-time, hence the name "black hole". 

How does time travel tie in to the black hole? Well, since it is a hole in space time, there a theories where the hole can transport to different places and possibly, different times. Think of this black hole as a tunnel, where the beginning is the black hole and the end is the white hole. The white hole is basically the exit where, unlike the black hole, spits out objects entering from the black hole. Considering this theory and the fact that it is technically a hole or rip in space-time, time travel could actually be possible. However, we couldn't really control it. 

There are many obstacles preventing actual travel via black hole, considering it would probably crush you when you enter it (unless you're traveling via KERR black hole). Overall though, this is just one other theory to time travel, one that might be actually accessible, although near impossible. 

Next time, on TARDIS Talk, we will be talking out the Cosmic Strings, yet another theory for time travel. No, its not a literal string if you're wondering, but more like a defect in space and time, kind of like a black hole.

Anyway, until next time my friends! Keep it classy.

Factors to Go Back - Part 1: Faster than the Speed of Light

Welcome time travelers, once again, to TARDIS Talk!

Today, I will be discovering and researching the fundamental concept of going faster than the speed of light in order to travel back in time. "Faster than light?", you ask? Well, it might seem a bit odd, but if you know Einstein's famous theory of relativity, then you will understand.... kind of...

I have actually found this type of information before, looking for theories. Of course, like every great thinker, I used the internet. Again, I used Google to search up stuff. Very resourceful aren't I? I came across one very interesting website who seemed to really know what they were talking about. This website was the LiveScience site.

LiveScience described the theory of time travel by going faster than light to great extent, explaining how the theory worked. But, what interested me first of all was that physicists are actually changing their mind about the possibility of time travel because of one such discovery: they found subatomic particles, called neutrinos, going faster than light. If this experiment is actually confirmed, the thoughts of time travel could actually be confirmed as well!

Now, onto the theory of relativity. When I first found this information, it came as a surprise to me how it actually worked in the case of time travel. It's a bit complicated to think of, I know, but it actually makes sense once explained a bit more.  It works like this: When you accelerate toward the speed of light, your experience of time changes in such a way, that a second for you, at that speed, would be much longer for the people traveling at normal speed. So, in relation to you (approaching light speed), the outside world becomes slower. Then, once you hit light speed, it stops. So, if this is the case, if we EXCEEDED light speed, would time flow backwards? With the information given to us, this type of theory would actually make some sense. 

Unfortunately, there are a lot of barriers to approaching, as well as breaking light speed, but if we could, time travel, as we know it, could actually be accomplished. So far, we already found neutrinos to achieve it, now we will need to figure out how we make a whole living body achieve that.... Maybe a radioactive boost? Hmm...

Anyway, NEXT TIME, we will be exploring, already existent cosmic phenomena, or more plainly, the black hole.

Goodbye! And if your head hurts from thinking about light speed and relativity and such, that's good BECAUSE it is a sign I am making progress in educating you. Till we meet again, in good fortune and fancy bow ties. 

Traveling to The Past

Hello everyone! I am wearing a bow tie today! I am very happy...

Anyway, TODAY, I will be discussing with you backwards time travel, its possibility, and, if it is possible, how we would be able to achieve it. We'll be talking about backwards time travel for quite a bit, so sit back and just read through these series of posts. This is probably the most common use of time travel ever seen on T.V. or thought about.

So, to find out about this information I went to The Library. Actually no, sorry, I just wanted to make a reference. (Hopefully you Whovians understand.) What I actually did was use the POWER OF THE INTERNET, mainly google, to find out the possibilities of backwards travel. 

The first thing to catch my eye was the HowStuffWorks site. The name itself seemed simple  so I decided that was my place to go.

What I found was familiar information, some that I had briefly covered in my last post. It talks about the theory of relativity, something that we talked about already, concerning the "faster-than-light" possibility of time travel (specifically, backwards). And it also proposes the idea of, rather than using space propulsion technology, using the existing cosmic phenomena: the black hole. The ways of travel are explained once again by this website, but what caught my eye was a law of physics, not referring to travel, but to reality. What they talk about, is the law of causality, or cause and effect.

The law of causality got me thinking about if time travel could actually be possible, not in terms of travel, but in terms of reality. Could I travel back in time without causing a paradox and utterly violating and quite possibly changing our way of reality? Could I travel back and not create an alternate reality? I started to think about this and came to a conclusion. This kind of violation can be prevented, only if we don't do something stupid, like go back and, oh I don't know, sabotage America to make us LOSE WORLD WAR II. Because, if we do something like that, it would surely create a paradox, because it changes one of the most influential aspects of the events that have already taken place, thus also making another reality, where Germany won. I know it's a bit morbid, but it's the most cliche example of alternate reality I could use.

I have already gotten an idea of the reality aspect of time travel which I will have to look deeper into, but for now, I will have to research travel options. What should I start with, light speed or black hole?

So, yes, for the next week or so, our time travel discussion will now be focused on the travel back in time.

And once again, I bid you farewell to your thoughts and your theories.

Goodbye!

The First Factor: Time Travel

Welcome back to TARDIS Talk!

For the next few weeks, we will be exploring the TARDIS's main function: Time Travel. I will be researching what time travel truly is, and how it can be achieved. This is a VERY big concept, with its many questions on the possibility for us to even achieve it, and the many other theories on how it may actually be possible.Of course, we will be talking about backward time travel as well as forward, but for the time being, we will be focusing on how time may even be traversed in general. 

There are many theories on how time travel can be achieved, so I googled the theories to see what I could get. I stumbled upon a website, Space.com, which thoroughly described the various theories. 

I found various premises in the research. A popular theory, being Einstein's theory of special relativity, addresses time slowing down or speeding up, depending on your speed, relative to something else. Then there are other assumptions for time travel such as the wormhole, the black hole, general relativity, and (for all you Whovians) the Time Vortex. There are many thoughts of time travel out there in the world, which I will be addressing some, if not most, of. 

So, Time Travel, traveling to and fro from point to point on the timeline of the world/universe. This is what I will be covering for the next few weeks or so, and hopefully I'll be able to cover enough ground to have an idea for what to do in the actual construct. What I'll have to find out first: What will I have to do to achieve light speed, make a black hole, and such other concepts? I must ponder on this awhile. 

And at this, I bid you, Farewell.

Josh

Into the TARDIS [Talk]

Hello Whovians and other mortals!

In this blog I will be learning about various things regarding the TARDIS, but will ultimately be in an effort to construct my own. I will be learning about time travel itself, finding ways to make it possible. I will also be studying how the TARDIS moves through space the way it does, rather than just moving like a car. I want to study this, because like all fans of Doctor Who and most physicists, I would like to travel through time and space, and make what seems to be only a dream for most scientists and Whovians, a reality. This blog is speaking to the many Whovians out there who have always wanted to traverse time and space in a TARDIS, and also to those who simply would want to achieve time travel. With this blog, I hope to "satisfy" their desire for time travel, and to give them insight on the possibilities of an actual time machine. Many of you will certainly expect many posts relating to research from physicists, theories of time travel, and various explanations regarding the features of the TARDIS. I hope this blog will be able to satisfy your need or desire to know what time travel truly and if it is truly possible. So for now, I bid you farewell, for I have much research to do ahead of me.

Thank You! Goodbye! Geronimo! Allon-sy! Fantastic! Etc. 

You're favorite TARDIS talker, Josh.
