If the Milkyways stars were grains of sand….

In celebration of the return of @blowtorch ....

Sounds of laughter shades of life are ringing
Through my open ears inciting and inviting me
Limitless undying love which shines around me like a million suns
It calls me on and on across the universe

It is hard to put all of that in perspective. But even if you put me on the farthest planet, the university that I went to would still find a way to contact me asking to donate to the school.

So you're saying that the chance of finding a good drummer is the musical equivalent of finding a galaxy in Bootes Void?

Only that said galaxy is more likely to stay in the pocket.

The Space shuttle the size of a small gym has to travel at 30,000 ft per sec. To escape earth…that is 10x the muzzle velocity of 30 cal. Rifle……let that sink in.

If this 30 cal. rifle barrel has a 1:12" twist, the bullet leaves the muzzle spinning 180,000 RPM.

So, what’s at the end of space?

We will never find out in our lifetimes. I'm okay with that.

Many people speculate and perhaps even invent an explanation. Unlike other animals, humans are driven by the need to find ways to correlate effects with causes. It makes us superstitious critters.

This is fascinating, indeed. And quickly overwhelms my visualization/comprehension capacities. So ol' Walt Whitman's response might be apt now. (Well, a bit later. It's 3:30 p.m. here.)

When I heard the learn’d astronomer,
When the proofs, the figures, were ranged in columns before me,
When I was shown the charts and diagrams, to add, divide, and measure them,
When I sitting heard the astronomer where he lectured with much applause in the lecture-room,
How soon unaccountable I became tired and sick,
Till rising and gliding out I wander’d off by myself,
In the mystical moist night-air, and from time to time,
Look’d up in perfect silence at the stars.

Most of the dots in the background of this image are other galaxies.

So, what’s at the end of space? Two theories I’ve heard are it doesn’t end, ever and it’s curved in on itself so that you would eventually finish where you started. Also, if, in the ‘it doesn’t end hypothesis, presumably the outer reaches are filled with nothing, zilch, nowt, a true vacuum. If we send electromagnetic waves through it, is it still a perfect vacuum, or has it then got something in it?

Or, since the universe is still expanding, if you were able to go to the edge of the universe and keep going, at a rate faster than the expansion of the universe, the universe would expand along with you.

Oh yeah, I suppose you counted 'em?

My left thumb is pretty much equal in size to my right thumb.

And it all weighs a lot more than it should. Dark matter is heavy. Therefore, a LP is made up of dark matter. I’m going for a lie down now……….

Avogadro once postulated that it was impossible to get a good pizza anywhere near his house. Some said he was just all gassed up when he made the remark.

This is exactly why I don’t like to eat candy on the beach.

Ok, let's just sum this all up....
