So would we travel through time forward, as we do now, and also to the right? Or could we move freely in the second dimension?

You'd probably have to get rid of the arrow of time for two-dimensional time to make any sense. Otherwise I think it would lead to a contradiction: moving forward + moving rightward = moving diagonally, but I have a feeling this diagonal time would be hardly distinguishable from 1-dimensional time.

Although if time travel is possible in 2D time, you might visit exciting new places - like epochs which are neither in the past nor the future. Maybe they would only happen when you visit them.

I don't see enough proof to think that time as a force exist so that is why we can't talk about 2D time, I think that all we have is energy and speed by which something happens, therefore no time but the illusion of time, and this time seems to go only in positive direction because speed can only be positive.

Time isn't a force, but part of a continuum called space-time. But it is something as it can flow differently from place to place. I couldn't tell you exactly what time is but the Theory of Relativity shows that there is in fact space and also time, and they are both united in a continuum that can dilate and constrict because of gravitational fields.

This sounds to me a lot like the humanity and divinity of christ mixing like water and wine, a bunch of hogwash :(

I don't know how it sounds to you, but the science is pretty clear about this stuff. You should check out all of the evidence for these things, like gravitational lensing for the distortion of space, or the dilation of time inside satellites' extremely precise clocks. If these clocks weren't designed specifically for time dilation, the Global Positioning System would have an error increasing with 10 km per day, or so. So when you'd try to see your position in midtown New York, it would show that you're in a corn field, or something similar.

Also, as particle accelerators bring particles to speeds close to the speed of light, the particles that would otherwise change states in a tiny fraction of a second, change state in a slightly bigger fraction of a second.

You should check out from time to time the scientific knowledge that humanity has managed to acquire so far. That's, of course, if you're interested in the way the world works. Sure, it may be strange at times, but it's also extremely beautiful.

And you think Relativity sounds crazy? Then just look up some of the principles of Quantum Mechanics. I would say there is a resemblance between the humanity and divinity of Christ and an electron which spins in opposing directions at the same time. Of course with the exception that the latter is science and not just a made up story.

 

And finally, if you still can't believe in the physicality of time, rest assured that the smartest people on Earth do believe in it.

@Radu Adreiu, I'm replying on my own post I can't reply on yours

It's not that I don't get quantum mechanics I read about it every day but I still don't see why we need time to calculate this calculations, you can substitute time with velocity and nothing changes. To me velocity seems more real than time. But we don't calculate with velocity because we are used to calculate with time.

I know this is not a popular subject but I'm entitled to my opinion.

You're certainly entitled to your opinion, but do you genuinely believe your opinion has any weight? Did you studied advanced physics? Did you at least resolve any differential equation or complex integral?

Your statement about velocity and time is non-sense really. Please, do check this stuff out and you'll find out for yourself that time does physically exist. But if you don't want to do this, then that's your choice, because I don't really care whether you understand physics or not. The important thing is that physicists do understand it better than everyone else and they say it's time that dilates and the speed of light in vacuum that is a constant. In fact, there are many constants that are related to each other, like the speed of light is related with the electromagnetic permeability of the vacuum.

Anyway, I just can't imagine how you can think that you're right and physicists are wrong... about physics. I bet you haven't actually had to understand advanced physics to see how hard it is just to learn the basic stuff, let alone to disprove Relativity.

Physics is understood with math... lots of it. So your opinion, no matter how good it may sound in your head, it's non-sense. The equations and, more importantly, the experiments say so.

Looking at people around me, I came to the conclusion that the dimension of time is actually fractal, and that its value is relative to the observer/subject. E.g., the dimension of time is roughly 1 for most, 'normal' people, but it tends to be close to zero for people who suffer from Alzheimer's disease, while It tends to be close to 2 for people who're subject to severe bouts of cognitive dissonance.

Ahem, if 2D time is still, what do before and after mean?

2D matter is impossible, only things that are massless can be 2D and they supposedly pop in and out of existance.  Which would explain particles in hawking radiation... Im assuming nothing to back that up, purely guessing.

There is a youtube video about m-space with an easy to follow cartoon of the eleven dimensions that describe time. You can print it out and color on it with your crayons. If you cannot find it, go to your local library and color on those books.
