For the record, *one* light year, the *distance* light travels in a year, at its constant speed of 186,000 miles per second, works out to about 5.9 TRILLION miles. That’s 5,900 billion miles! ...in ONE light year. This thing they estimate at 10,000 light years away. Meanwhile, there are galaxies in our universe that are over 12 billion light years distant.
Dang man, looks like it’s headed straight for us...
I thought sound required a medium that would support the waves - is there a speed of sound in interstellar space?
Never mind, I looked it up:
Speed of sound in interstellar space is 10 - 100 km/s (as opposed to .34 km/s in air at sea level and 1.5 km/s in water).
Seems like scientists would be more specific unless this one assumed the high end for his reference about it exceeding the speed by several magnitudes.
“The wandering black hole was discovered lurking just outside a supernova remnant, a shell of expelled material left behind after a massive star explodes.”
According to the astronomy pros, many of the atoms in our bodies, the heavier ones, were created and/or once inside one of these huge exploding stars.
An expanding velocity that slow?
Caught my eye, too. A big “huh”?
Wiki: “The vacuum of intergalactic space is not devoid of matter, as it contains a few hydrogen atoms per cubic meter. By comparison, the air we breathe contains about 10^25 molecules per cubic meter.”
Not much of a medium to conduct sound, is it?
When God said "let there be light" He spoke it in a big way...
Looks like the view from the bottom of a glass sink.
Mainstream cosmology is a mess of assumptions piled upon more assumptions and justified with fancy arcane math. Sometime believing is not seeing.
As Niels Bohr once said to a smug young lecturer, “You have told us more than you can possibly know!”
Nope, which makes me wonder why it is so much faster in space than in air or water since the denser water conducts it almost 5 times as fast as the thinner air. Must be it uses wormholes......

Does seem very slow for this sort of thing. The earth orbits the sun at about 18 miles per second. And the sun orbits our Milky Way galaxy at roughly 130 miles per sec.
I agree with all of that.

A few hydrogen atoms per cubic meter?? Hard to imagine any sort of "ripple" or "wave" effect going on in that sparseness.
Still not bigger than 19 Trillion Dollars in debt, sadly.
Yes, but nearly as much as Bill Gates' net worth. :)

In a medium, speed is not related to density.
