Astronomy Picture of the Day - CMB Dipole: Speeding Through the Universe
APOD.NASA.gov ^ | 3 Apr, 2022 | Image Credit: DMR, COBE, NASA, Four-Year Sky Map

Explanation: Our Earth is not at rest. The Earth moves around the Sun. The Sun orbits the center of the Milky Way Galaxy. The Milky Way Galaxy orbits in the Local Group of Galaxies. The Local Group falls toward the Virgo Cluster of Galaxies. But these speeds are less than the speed that all of these objects together move relative to the cosmic microwave background radiation (CMBR). In the featured all-sky map from the COBE satellite in 1993, microwave light in the Earth's direction of motion appears blueshifted and hence hotter, while microwave light on the opposite side of the sky is redshifted and colder. The map indicates that the Local Group moves at about 600 kilometers per second relative to this primordial radiation. This high speed was initially unexpected and its magnitude is still unexplained. Why are we moving so fast? What is out there?

The Galaxy Song (Monty Python’s The Meaning of Life)

Whenever life gets you down, Mrs. Brown
And things seem hard or tough
And people are stupid, obnoxious or daft
And you feel that you’ve had quite enough....

[Verse 1]
Just remember that you’re standing on a planet that’s evolving
And revolving at nine hundred miles an hour
That’s orbiting at nineteen miles a second, so it’s reckoned,
A sun that is the source of all our power
The sun and you and me and all the stars that we can see
Are moving at a million miles a day
In an outer spiral arm, at forty thousand miles an hour
Of the galaxy we call the ‘Milky Way’

[Verse 2]
Our galaxy itself contains a hundred billion stars.
It’s a hundred thousand light years side to side
It bulges in the middle, sixteen thousand light years thick
But out by us, it’s just three thousand light years wide
We’re thirty thousand light years from galactic central point
We go ‘round every two hundred million years
And our galaxy is only one of millions of billions
In this amazing and expanding universe

[Verse 3]
The universe itself keeps on expanding and expanding
In all of the directions it can whizz
As fast as it can go, at the speed of light, you know
Twelve million miles a minute, and that’s the fastest speed there is
So remember, when you’re feeling very small and insecure
How amazingly unlikely is your birth
And pray that there’s intelligent life somewhere up in space
‘Cause there’s bugger-all down here on Earth!

Thank you for posting that lyric. I truly laughed out loud and it put a smile on my face for the first time on this dreary day.

You are most welcome, dayglored...as soon as I began reading the article, the song popped right into my head...

If we can’t find things to laugh about in this world, it will eat us alive. So I look where I can...:)

LOL. Okay, it is time for me to watch that movie again..."Roger the Shrubber"!!!!

Roger the Shrubber: Are you saying Ni to that old woman?

King Arthur: Um, yes.

Roger the Shrubber: Oh, what sad times are these when passing ruffians can say Ni at will to old ladies. There is a pestilence upon this land, nothing is sacred. Even those who arrange and design shrubberies are under considerable economic stress in this period in history.

King Arthur: Did you say shrubberies?

Roger the Shrubber: Yes, shrubberies are my trade. I am a shrubber. My name is Roger the Shrubber. I arrange, design, and sell shrubberies.

And to top it all off, "Monty Python and the Holy Grail" was done on a total budget of...

... ready? ...

$400,000 US. That's not a typo.

Less than half a mil. Funniest movie of all time, or possibly second to "Airplane".

I saw that image and instantly thought it is like a Cosmic Yin and Yang symbol.

To: All
Lord, it's the same old sun, moon and stars
Who's really steering this train?
meteors trying to crash our scene
I ask what does it all mean?
and I look for answers in the sky

Somebody said when I grew up
I'll know the meaning of life
But the more I read the news
the more I get the blues
All I can do now is pray

I spent my life reading the Good Book
but my life is in such disarray
I don't want to be Satans slave
but I'm speeding my way to the grave
Love your neighbor is all I know to say

Animaniacs - Yakko’s Universe
https://www.youtube.com/watch?v=OmfAyK6CeIg

Everybody lives on a street, in a city
Or a village or a town for what it’s worth
And they’re all inside a country which is part of a continent
That sits upon a planet known as Earth
And the Earth is a ball full of oceans and some mountains
Which is out there spinning silently in space
And living on that Earth are the plants and the animals
And also the entire human race!

It’s a great big universe
And we’re all really puny
We’re just tiny little specks
About the size of Mickey Rooney
It’s big and black and inky
And we are small and dinky
It’s a big universe, and we’re not!

And we’re part of a vast interplanetary system
Stretching seven hundred billion miles long
With nine planets and a sun; we think the Earth’s the only one
That has life on it—although we could be wrong
Across the interstellar voids are a billion asteroids
Including meteors and Halley’s Comet too
And there’s over fifty moons floating out there like balloons
In a panoramic trillion-mile view!

And still it’s all a speck amid a hundred billion stars
In a galaxy we call the Milky Way
It’s sixty thousand trillion miles from one end to the other
And still that’s just a fraction of the way
‘Cause there’s a hundred billion galaxies that stretch across the sky
Filled with constellations, planets, moons and stars
And still the universe extends to a place that never ends
Which is maybe just inside a little jar!

It’s a great big universe
And we’re all really puny
We’re just tiny little specks
About the size of Mickey Rooney
Though we don’t know how it got here
We’re an important part here
It’s a big universe, and it’s ours!

1. What song is that lyric from? It's a good one.

2. Your tag line makes a good meme:

Instead of:
"BUILD BACK BETTER"
How about:
"PUT IT BACK THE WAY YOU FOUND IT"?
