Picture of How to Travel Through Time
In this Instructable, I will explain how to travel through time.*
Try not to create any paradoxes. Later I might add a section explaining how it works.

*Results may vary.

Step 1: Materials

Picture of Materials
To travel through time as demonstrated in this Instructable, you will need:

- Handheld Portal Device*
- Nearly anything capable of traveling at 80-99% of the speed of light.


- A strong understanding of the theory of relativity.


*I haven't seen anything like this yet. But, I've heard a company called "Aperture Science" is developing something similar.

Step 2: Time Travel

 To travel through time:
First, use the Handheld Portal Device to create a portal on any flat surface, preferably a wall. Then, create another portal on/in your chosen method of near-light speed. Now, have the second portal travel at near-light speeds for a few days, depending on how far you want to travel into the future/past. Then, just simply walk through one of the portals. To go into the future, walk into the portal that was traveling at near-light speeds. To go into the past, walk into the portal that remained stationary.

Step 3: Paradoxes

Picture of Paradoxes
 The hard part of time travel is paradoxes. Basically, you can travel through time but you can't intenionally change it. Let's say you wanted to keep Lincoln from getting killed, so you go back and stop it. But then it never would have happened, so you never would have gone back to change it. So then it would have happened because you never went back to change it. But then since it did happen you would go back and stop it, and so on.

A way to avoid that paradox is to go back in time for two reasons. Like you wanted to warn Lincoln that he will be shot by Jon Wilkes Booth and at the same time, you wanted to tell him a funny joke. Than when Lincoln no longer dies, in the future you will still go back in time to tell him the joke.

The hard part is when a mad scientist assembles a gun in front of the to-the-future portal and shoots the gun at himself through the to-the-past portal. (I like this one a little better than the grand father paradox)

Great Instructabel!
If you go to the past and change ANYTHING!!! Then the future would be changed and it would destroy the space time continuem!

How so?
Just because (dont tell anyone, but I have the same first pic as you, you coppied me!)
the clock is madness.

I just want that clock! Where did you find the pic?

I want a clock too.

 I just Google searched "time travel".

Unfortunately, ASHPD-type portals disintegrate upon movement. They can only be used on stationary surfaces, so the the object moving at light-speed would need to have a huge amount of mass (like a very large planet) in order to downplay its movement.

Assuming you used the Enterprise as the fast-moving object, the inertial dampeners would probably neutralize that effect.

Unfortunately, your concept couldn't let you travel to a time before the initial portal was placed. Hypothetically: Assuming a self-consistent universe: the moment the initial portal is in place, you could potentially come through it from the future and give yourself information about something (stock market information for example (the possibilities are endless!)) and leave, as long as your future self had been in the same situation in your current place. This would only leave an ontological paradox as to the origin of the information transferred and could be remedied if the information is found by you in the time between visits. I hope this made sense; I just wanted to write something interesting!
