What if we are alone in Milky Way ?

[Quasar44]

That's the paradox ... the MW should be full of life, everyplace we look ...

I think we're not looking close enough ... microbes at 50 light-years distance? ... we'll need bigger telescopes ...

Why was earth only stuck on single cell
organisms for like 3 billion years???

They have arrived just in time for us all to take a Giant Step forward with the Donald leading us .

To my <limited>understanding, every American potus going back the Eisenhower had some sort of connection 'Lu

I'd wager they all fell in line w/deep state

Would 'the Donald' break the mould?

well......i'll just say thinks may not be so boring here.......

There are 2 trillion galaxies now and our MW is only 1

Our MW has billions of stars and trillions of planets
20 billion earth like planets

Yet zero sign of any intelligent life or anyone finding us ??

Are we all alone ??

Yes

 

[sparky]

There's a starman waiting in the sky
He'd like to come and meet us
But he thinks he'd blow our minds
There's a starman waiting in the sky
He's told us not to blow it
'Cause he knows it's all worthwhile
He told me
Let the children lose it
Let the children use it
Let all the children boogie

~S~

 

[Carl in Michigan]

Yes

Are we all alone ??

Yes

We have to rethink the definition of alone.
Is it that there is no-one else. Or just no-one within walking distance.

Shortly we will be able to scan deep space for biomolecules.

I have no doubt we'll find plenty of them.

Building Blocks To DNA And RNA In Deep Space Conditions Produced In A Laboratory - Astrobiology

The synthetic production of a critical building block called methanediamine for the first time by researchers in University of Hawaiʻi at Mānoa’s Department of Chemistry could lead to key insights into the origins of life.

Yes but a civilization only a few million years ahead of us would have easily transversed the Milky Way by now !!

Also something called the , Dark Forest hypothesis

Advanced civilization don’t want to be destroyed by even more advanced ones - so they stay hidden

The issue is Einstein ... he might actually be right ... the speed of light is as fast as anything can go ... bar none ... it will take well over 2 million years to reach the Andromeda Galaxy ... ten times longer than humans have existed ...

Even if Einstein's wrong ... the energy needed to accelerate, then decelerate ... and then accelerate/decelerate back home ... is enough energy to power all human civilization for the entire 4 million years it would take ...

Plus we forget the lessons of H.G. Wells' War of the Worlds ... humans didn't destroy the Martian invasion ... bacteria did ...

Einstein says if you curve space enough you can build a bridge from one point to another. It's called the Einstein-Rosen bridge.

Even if Einstein's wrong ... the energy needed to accelerate, then decelerate ... and then accelerate/decelerate back home ... is enough energy to power all human civilization for the entire 4 million years it would take ...

You can power your spaceship using the Casimir effect. No fuel needed.

Send a robot first. Collect samples.

Cool ... without that pesky 3rd LoT, perpetual motion is a reality ... you should talk to NASA, they need your help ...

Do you know the difference between "force" and "power"? ... just curious is all ...

Nah, they already know all about it.

Do you know the difference between "force" and "power"? ... just curious is all ...

Of course. I went to school.

 

[ReinyDays]

Nah, they already know all about it.



Of course. I went to school.

... and in this school ... they claimed there's more than two natural forces in the universe? ... let me guess ...

Hogswort ...

You claimed "no fuel needed" ... only magical forces can do that ... I don't think you know what power is, because you're using the word wrong in your sentences ...

"No fuel needed" ... do you know what "power" is? ...

Van der Waals forces ... Linus Pauling proved these are electro-magnetic 100 years ago ... EM forces require fuel ... or no power ...

Nothing at all terrifying.

Probably life exists everywhere it can, just as on earth. Probably we will never make contact with intelligent life elsewhere due to all the obvious elements of vast time and space. Absolutely, it makes no existential difference. The presence or absence of others changes nothing about the essential questions of "being" for the individual. In a way, we are, each of us, alone and isolated in our unique, personal envelop of flesh and mind. We see and hear and believe that it is real, yet our dreams reveal that it could all, also, be a dream. That can be pleasant or unpleasant to contemplate, as one chooses, but it need not be. Most of all, it would not be changed simply by knowing that there appears to be other life forms who have the same situation.

lol

Linus Pauling? The vitamin C guy?

No. Van der Waals forces are caused by correlations in quantum polarization.

Yeah, I suppose you could say quantum fluctuations represent "fuel", in an abstract roundabout kind of way. But they're not a consumable like lox or iodine.
