Does Light move outwards from the sun as a 'Expanding Spherical shock-wave bubble'?

as far as i know the speed of light is constant and the only thing that realy effects it is massive amounts of gravity therefore it should radiate from the sun in all directions at an equal pace. I do not think it expands like a bubble

Sorta. Its more of an inverse square. Since the speed of light is only constant in a vacuum, and since stars are not uniform temperature in all spots, it will be slightly off. Gravity too will warp and bend the path of electromagnetic radiation, making it curve. We actually use this property to see things that we normally could not -- We use galaxies as lenses, literally.

However, one thing is very important: Light is both a wave AND a particle, at the same time. It would be better to say it propagates in all directions through the false vacuum of the interstellar medium. In a true vacuum however, yes, light would expand uniformly in all directions, appearing as an expanding sphere.

But we don't live in a true vacuum, so yeah.

Yes but not a bubble it's a never ending stream, but it will end of course when the sun blows up at the end of its life
