:) Thanks man. And I agree, technology will help us to understand our theories! :)

I have a diploma in Robotics and Automation. I love my job; a lot of real life problem solving including design and automating processes using varies programming solutions. However, sometimes I regret not studying Physics. I always been fascinated by it! It been a while since I did physics and...

@Drakkith Wow, that is really interesting! I have to read you comment few times so I understand the concept, lol. At least you showed me which door to walk through. You showed me which concepts are involved to understand my question. That's kool man, Thanks!

Thanks for the respond @DaleSpam. I guess I have to understand the problem from the general relativity prospective. Sucks. I thought I can understand it logically without needing to go into the depth and complex equations (at least for me sounds complex). This is one of those things if your...

Logically speaking, light travels in space. If space is a straight geometric plane, light should travel in a straight geometric line. If space is a zick zack geometric plane, then light should travel in a zick zack geometric line. That's the bottom line of it. In a zick zack space, if the light...

Hey Drakkith, Here is the confusion, "...the depression in the sheet should not be viewed as an actual depression, but merely a change in the geometry of the surface..." So curvature is not a depression? If you have "a change of geometry of a surface", for example a parabola, isn't that change...

Thank you guys for your replies. @256bits, "gravitational well" that's exactly what I was thinking. This is why I showed my red line as it is "falling" in this gravitational well and quickly exiting. It is like looking through a curved fiber optics. You can see the other side through the fiber...

Hello DrewD, My problem is visualizing how space is curved at gravity and how the light travel in this curvature? Initially I thought there was some sort of "gap in space" or "interruption" at gravity point, which affects the path of light. That's why I made a 2-D universe, just to make it as...

Nice! Thanks :) In 3-D world, it should work the same. Can that bent be measured?

So like this? Where the red line is the path of light?

"but when you move to a reference frame like the one you are talking about, the light's path would be non-linear for a time." How can you say this in other words?

If I was standing on the opposite side of the mattress and you through a marble from the other side, I will see the marble until it is bent. But for the light, I will still see it, right? How is that possible?

Thanks for the respond. I think bowling ball on a mattress is a deceptive picture to the mind because the mattress is representing a "plane" where an object can travel on. Since the mattress is bent, there is technically a "virtual gap" because the object can't travel on a straight line on the...

Hello All, My background in physics is very basics. So I apologize in advanced if a make silly logical or empirical error. As shown in the attached picture, for the sake of simplicity, imagine the picture is a 2D world. Let's say we are being from 3D world looking directly at this world...
