Truly a revolutionary. A visionary of our modern times. Equal parts Scientist and Philosopher. I only wish more people could strive to be like him.

What you wrote made me think of this video. I would have loved to meet this man.
As sound cannot travel in a vacuum even more so in a vacuum that did not even exsist at that point
The Perseus cluster black hole's B-flat, by contrast, is 57 octaves below middle C or one million, billion times lower than the lowest sound audible to the human ear! In terms of frequency (the time it takes a single sound wave to pass by), the lowest sounds a person can hear is 1/20th of a second. The Perseus black hole's sound waves have a frequency of 10 million years!
You may be wondering how a sound wave can travel through space. After all, sound waves require some sort of stuff to move through. This stuff, called a medium, can be air, water, or even solid rock. And space is thought of as lacking any medium because it is a vacuum.
In fact, space is not a pure vacuum but rather it contains stray bits of stuff -- gas atoms and dust of varying amounts. In the case of the Perseus cluster, the gas throughout it serves as the medium through which the sound waves coming from the central black hole travel.

The sound waves were indirectly detected using the Chandra telescope because the cluster gas is very hot and thus emits an especially energetic form of light called X rays, as well as less energetic visible light. And the gas is so hot because of the effects of the black hole.
More than an acoustic curiosity, these sound waves transport energy that keeps gas throughout the cluster warmer than it would otherwise be. These warmer temperatures, in turn, regulate the rate of new star formation, and hence the evolution of galaxies and galaxy clusters. This makes the findings far more significant for understanding the astrophysical evolution of the Universe.
The Perseus sound waves are much more than just an interesting form of black hole acoustics, said Steve Allen, also of the Institute of Astronomy and co-investigator in the study. These sound waves may be the key in figuring out how galaxy clusters, the largest structures in the Universe, grow.
Astronomers will now analyze other galaxy clusters for similar sound waves.

I can only suggest imagining a glass marble thrown hard at a wall exploding into a millions pieces going in every direction.
Then of course....the pertinent question then becomes...(c'mon folks...you know it's comin'..)..WHO THREW the marble in the 1st place!
Is it possible the Marble wasn't thrown, but rather propelled by natural forces we have yet to uncover and understand? Most of the known universe is dark matter, and most of the energy in the universe is dark energy. We have at best only cracked the door to our understanding of the universe. The trickles of light flowing in from that cracked door can give us clue to what may lie inside the room, but until the door is finally opened, nobody can know for sure.

But the thing you have to keep in mind is that Inflation (AKA The Big Bang) is still only a theory.

You have trouble believing anything from scientific sources? Are you one of those idiots who will take everything they're told on blind faith but then argue against anything that's been proven with science?
In ancient times, when mankind didn't know how anything worked, they explained everything by saying "oh, that was God that did that".
Now, we have science to show us how stuff works, but BILLIONS of people still think God was responsible for everything.
Even the POPE this week said that "to think God did everything was ridiculous" and endorsed the Big Bang.

The theory has already been covered, but I am curious. You have trouble believing in science and scientists, but are apparently capable of using a phone or computer to access the Internet? I'm guessing that -- for you -- accessing information on the Internet is a lot like contacting the spirits of the dead via medium, or with the help of Tarot cards? Do you pray when you start your car in the morning? Or operate an oven or radio? Do you believe there is a casual relationship between television and witchcraft? How do you feel about having your picture taken? Does it feel as if the photographer has stolen a piece of your soul?
I'm not trying to be rude. I am just wondering how you navigate the actual world, which is immersed the product of centuries of scientific theory, measurement, observation and analysis.

As for the Big Bang, I'm not buying it. Just another psyop to subconsciously promote promscuity.
