Light speed and gravitational matrix

AI Thread Summary
Light travels at a constant velocity within a medium, while gravity, according to Einstein, displaces the space-time matrix based on mass. Massive objects bend light, leading to a phenomenon known as gravitational lensing. Shapiro's theory indicates a time lag for light as it passes around these massive objects. The discussion raises questions about the viability of a propagation matrix and its relationship to gravity, as well as the nature of time dilation in a vacuum. The complexities of these theories highlight the challenges in understanding the interplay between light, gravity, and the concept of a transmission medium.

Light appears to travel at a constant velocity in a constant medium/matrix. According to Einstein, gravity is the opposing force of displaced space/time matrix by mass. The more mass, the more the gravitational displacement.

Light is "bent" around massive objects.

Shapiro? says there is a "time lag" of light passing around massive objects.

Questions:

Why did the propagation of light in a matrix theory die?

Why can't the propagation matrix be the same gravitational matrix?

Why can't the time lag be accounted for by the slowing of light in a denser matrix?

Not sure what this "matrix theory" you are referring to is, but time dilation is often tested in a vacuum, so it is very clearly independent of a transmission medium.

not at all clear to me as I don't know how you would evacuate gravity
 
Gravity is not a transmission medium. When Russ talks about transmission medium, he's talking about like glass, or water, or air that the light has to pass through.
 
Is a homemade radio telescope realistic? There seems to be a confluence of multiple technologies that makes the situation better than when I was a wee lad: software-defined radio (SDR), the easy availability of satellite dishes, surveillance drives, and fast CPUs. Let's take a step back - it is trivial to see the sun in radio. An old analog TV, a set of "rabbit ears" antenna, and you're good to go. Point the antenna at the sun (i.e. the ears are perpendicular to it) and there is...
3I/ATLAS, also known as C/2025 N1 (ATLAS) and formerly designated as A11pl3Z, is an iinterstellar comet. It was discovered by the Asteroid Terrestrial-impact Last Alert System (ATLAS) station at Río Hurtado, Chile on 1 July 2025. Note: it was mentioned (as A11pl3Z) by DaveE in a new member's introductory thread. https://www.physicsforums.com/threads/brian-cox-lead-me-here.1081670/post-7274146 https://earthsky.org/space/new-interstellar-object-candidate-heading-toward-the-sun-a11pl3z/ One...
