What is the Path of Light through Strong Gravity?

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 not expert at the topic, you simply won't get it. :(

I don't agree. Sure, you need to know the equations to actually do GR and solve problems, but I don't feel you need to know the math to grasp the basics. GR is, at its core, a theory of geometry, and it takes only a little imagination to extend the more basic concepts of geometry to GR. But you have to have some understanding of those basic geometry concepts, many of which weren't taught to you in high school or college unless you specifically took advanced math courses.

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!

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 "not everyday" mathematics. In my free time, I try to review what I've learned and want to learn new things about physics and math. Hopefully, I'll catch up soon. :)

Never regret doing something that has tangible benefits like robotics and automation. Heck, if anything we need MORE engineers and people like yourself. Engineers are who solve real world problems and can be some of the most creative people in the world. A lot of our current unsolved problems in physics is the result of the lack of data, not a lack of brainpower. We are effectively waiting for technology to catch up to theory to get more data to show us which way to go.

My problem is visualizing how space is curved at gravity and how the light travel in this curvature?

You have to understand the concept of geodesics on curved surfaces. The lower picture in the below link gives you an approximate idea:

However, note that this purely spatial curvature just explains half of the light bending. To explain the full amount you have to include the time dimension, and consider space-time curvature. But this gets very hard to visualize.

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