Life Off and On Earth

Here's some good news. Since the Biden administration took over, I estimate that the daily volume of news stories we all really need to be aware of has fallen by about 33 percent. Thus, the headline summary I publish each day can be proportionately shorter.

That opens up the comparative luxury of noticing some of the longer-term advances in scientific knowledge that may soon drastically reshape our understanding of life. Later this year, for example, a powerful new telescope at the Vera C Rubin Observatory in Chile will begin taking pictures of everything visible in the night sky.

That may help us resolve the mystery of "Oumuamua" -- the  strange object that passed by earth in 2017 that Avi Loeb, Harvard's top astronomer argued was most probably the product of an alien civilization. This is consistent with Loeb's contention that life on earth is hardly unique in the universe but is an extremely common occurrence.

Loeb's argument is based on only on the object's strange characteristics and behavior but on the logic of pure math. He notes that that since rocky planets with liquid water and the chemistry to support life formed 13.8 billion years ago, by now billions of galaxies – each home to billions of Earth-like planets – should have formed. 

If Loeb is correct, there are literally trillions of pieces of Oumuamua-type junk surrounding us in the universe and soon we should be able to detect them. The telescope at the Vera C Rubin Observatory will be our tool for testing that hypothesis, and it goes into action sometime this year. <https://en.wikipedia.org/wiki/Vera_C._Rubin_Observatory>

It's difficult to imagine any bigger news story than the one that would announce "We Are Not Alone." That would make all of this political bickering we are subjected to rather petty by comparison, no?

(Note: Oumuamua is a Hawaiian word meaning  “scout” or “messenger sent from the distant past to reach out to us.”)

In the spirit of pettiness, it's notable that Democrats and Republicans are squabbling over how much and how soon further pandemic relief will reach us average Americans, while the logistical hurdles to getting Covid vaccines into our arms are proving daunting.

The way politicians adjust their positions based on polls has long been reprehensible, but the dance many Republican Senators are currently doing is pathetic. They claim they won't convict Trump even if they think he is guilty of inciting the January 6th Capitol mob because most Republicans still back him.

You know, I've quoted everyone from Edward R. Murrow to philosophers to country music singers about the truism that if you don't stand up for something when it matters you don't really stand for anything at all.

I would hope we all want our time here to matter. Thus all conscientious Americans need to attack the scourge of racist, extremist thinking that has infected the Republican Party. We need to band together to rid ourselves of conspiracy theories and recommit to a society guided by honest information developed by good journalists, scientists and artists.

After all, when we greet our first alien visitors, we don't want to be embarrassed by the primitive state of affairs here on little old Earth. They -- and we -- deserve much better than that.

She packed my bags last night pre-flight
Zero hour 9:00 a.m.
And I'm gonna be high
As a kite by then
I miss the Earth so much I miss my wife
It's lonely out in space
On such a timeless flight
And I think it's gonna be a long, long time
'Til touchdown brings me 'round again to find
I'm not the man they think I am at home
Oh, no, no, no
I'm a rocket man
Rocket man, burning out his fuse up here alone
And I think it's gonna be a long, long time
'Til touchdown brings me 'round again to find
I'm not the man they think I am at home
Oh, no, no, no
I'm a rocket man
Rocket man, burning out his fuse up here alone
Mars ain't the kind of place to raise your kids
In fact it's cold as hell
And there's no one there to raise them
If you did
And all this science
I don't understand
It's just my job five days a week
A rocket man
A rocket man
And I think it's gonna be a long, long time
'Til touchdown brings me 'round again to find
I'm not the man they think I am at home
Oh, no, no, no
I'm a rocket man
Rocket man, burning out his fuse up here alone
And I think it's gonna be a long, long time
'Til touchdown brings me 'round again to find
I'm not the man they think I am at home
Oh, no, no, no
I'm a rocket man
Rocket man, burning out his fuse up here alone
And I think it's gonna be a long, long time
And I think it's gonna be a long, long time
And I think it's gonna be a long, long time
And I think it's gonna be a long, long time
And I think it's gonna be a long, long time
