Many people believe the fallacy that anything imaginable is possible. This has led to all sorts of ridiculous beliefs throughout the ages.
Time travel is one of those subjects that has always irked me. Let’s be quite clear: time travel is possible, gentle reader, you’re doing it right now. We are all moving forward at the precise speed of 1 second per second.
Time travel in the other direction makes no sense. Although we can imagine the possibility, it makes no sense to anyone who has grasped the concepts of Newton’s Laws of Motion. It just doesn’t. I know a lot of physicists think it is possible, and I know I’m not a physicist seeking funding to study such silly phenomenon, so I’ll speak out on the silliness.
Time is not a timeline, although we can create a timeline, it does not necessarily follow that we are free to move to the left and right along the timeline.
Time is a result of movement, it is the result of moving from one place to another. Going back to where you were is a second movement, it does not undo the first movement although you are in the same place you started. Easy concept to grasp. Trying to do this faster won’t change the fact. Just look at the concept: if you go back in time when you go faster than light you would immediately be returned to the point just before you went faster than light.
You can slow time from your perspective, time dilation has been proven with synchronized atomic clocks put on separate jets, one flown east and one flown west around the world. The clocks were no longer synced when the planes landed. Does this imply anything about time moving backward after reaching light speed? Nope. It proves Einstein was correct. Frames of reference are real, which explains the eccentricity of Mercury’s orbit. The reader is encouraged to utilize their search engine of choice for more clarity on time dilation, this is outside the scope of this post.
The belief that “Einstein’s theories allow time travel because at faster than the speed of light time moves backward” is absurd. That’s just simply not a conclusion of anything I’m aware of Einstein writing. It’s just a straw grasped at by those with over active imaginations and under funded research grants.
And given that Einstein proved that we could never travel at light speed, the point is moot, we’ll never get there, we’ll never go faster. This limit is due to the fact that objects gain mass with speed, at speeds close to the speed of light, it requires energies approaching infinity to move faster, therefore it requires infinite power to accelerate mass to the speed of light.
So, what’s light then? We don’t know exactly. What we do know is that it travels from the Sun to the Earth in 8 minutes and 23 seconds. It takes time to get here, and we see it, so it’s not moving backward at all.
Also, we know that physicists will still utter silliness such as:
However, because of the probabilistic nature of quantum mechanics, Prof Lloyd’s method seems to avoid this [grandfather paradox]. Anything caused by the time travel must have had a finite probability of happening anyway, so paradoxical impossibilities are out.
Complete silliness reported by the Telegraph here.
I could be wrong, physicists are smart people after all. However every single one of them that has successfully traveled backward in time has died in the vacuum of space, given that the Earth moves through space and would not be where it was at the time of travel. The only way around this issue is to now suggest because space-time is the actual medium of the Universe that travel backward in time automagically imparts the momentum necessary to travel to the previous location…oops, we’ve just moved which Newton showed takes time.
Time to pass the bong Prof Lloyd, you’ve had enough man.
Maybe I’ll grow wings tonight and fly in to the office tomorrow, I’ve thought of it, so it might happen!
