I worked at Keck observatory for almost ten years.
Was mentored by the world’s best astronomers.
Some even corrected me on my Electronic engineering,
you cannot ignore physics.
Light bends or disappears in the force of gravity.
Light has mass!
Stars are out there,
Due to distances involved some may be gone,
But unless you are God our speed limit
is about 300 million meters per second.
Nearest star after our sun is about 4 years away.
Every description of light or photons says it doesn’t have mass. How are you able to describe light with a mass?
“But unless you are God our speed limit
is about 300 million meters per second.”
Stars are receeding away from us faster than that.
Never mind - it acts like it has mass relative to gravity.
“Nearest star after our sun is about 4 years away.”
At 30,000 mph it is about 10,000 years away.
Is it the measure of it’s energy?
Light doesn't have mass. Light has energy and momentum, but no mass.
