I also agree with you that this article is full of baloney. We're just discussing at what step of the baloney we should call it baloney. :D
Besides all those other assumptions that we both mentioned, i think this whole radio wave communication is the first step of the baloney that caught my eye.
I mean, what kind of radio transmission did they sent? A UHF transmission? And how many obstacles did this transmission run through which would slow it down compared to light?

Then the rest of the baloneys follow.

My baloney started with the speed of light.

For most of my life I believed the speed of light was the speed limit of the universe. They say nothing can go faster than that. Allegedly if you get up to an appreciable fraction of that speed, time slows down for you.

But what is the objective stationary object against which we are measuring this speed? The center of our galaxy? The center of the universe?

Also, what about stars that are moving toward ours? When light from them reaches us it is moving faster than the speed of light relative to our planet. "But it was moving at the speed of light when it was emitted from the star that made it." Yeah, so it has its own speed of light plus the speed of the star. No matter what object you choose to measure its speed by... Unless every star is perfectly still, there MUST be some light that is moving faster than the speed of light.

Actually scientists use this to determine the vector of different stars. Light gets more red as the object moves toward you, and more blue as the object emitting it moves away from you. That's one of the ways light acts like a wave. So if light was NOT moving slightly faster or slower than the speed of light, red/blue shift wouldn't work.

Good points free thinker. :D
Why the redshift if the speed of light is absolute? Because the wave is stretched out the scientists say, especially while the Universe is still expanding.
Also the expansion of the Universe could be faster than light, not sure what the scientists say about this, but my next question to them is: Where is this Universe expanding into? Nobody knows this and we can't know it.

The objective stationary object to measure the speed is Point A to Point B in a vacuum, scientists say.

And the effect of time was measured with two twins that were sent in space.
Twins Study | About - NASA
The one who was up there in orbit is a few milliseconds younger than his twin brother since Time for him ran slower up there.
Scientists also say that if you do ONE SINGLE orbit near a black hole with a ship, 1000 years would have passed on Earth when you return.

Now we need to order some appetizers to continue this discussion. :coffee:

Between the centrifugal force of such an orbit and the shear force of being so close to such a small, strong gravity well, you would be a thin red paste on the wall if you tried to slingshot around a black hole that close.
