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.
An expanding velocity that slow?
Looks like the view from the bottom of a glass sink.
Imagine being an astronomer and seeing this heading our way.
Being able to predict when the planet and the entire solar system will cease to exist.
So black holes are hard to see in space because they’re black.
Tricky rascals, those black holes.
“So what could possibly send such a huge stream of molecular gas speeding out of a supernova remnant?”
Off hand, I’d say it was those three burritos for a buck down at the C-store.
“You didn’t stop me for speeding. You stopped me because I’m black!”
Looks like the first disturbing symptom of a STD.
On the other hand, perhaps black holes are the ultimate treatment for erectile dysfunction?
Black holes are racist.
I saw black hole once . . . it was awful! I believe it was down on the south side of town. Drugs, stealing,crime, all kinds of stuff going on. I sure don’t want to run into one in space!
A close-up shot............
Superman was faster than a speeding bullet but can he out race a speeding COSMIC bullet? I don't know...this might be a race that even Superman can't win.
