I like the way this is put by Neil deGrasse Tyson.

It really explains how tough it would be for us to find intelligent life in the universe.

Not all.  One of the rockets (a NEW one!) did not return to the landing pad. 

Oh my god, what a landing. They programmed all that so nicely. The future is here .
Thanks for sharing.

I am reading a book about anti-gravity right now.   I can't put it down!   

I wondered why the baseball was getting bigger.... then it hit me!

You believe in gravity, liar.   It keeps your fat ass in a proportional position for your fingers to touch the keyboard. 

^^^ Cupping Musk's balls are we?


I have no problem outing gravity as the bullshit theory that it is BTW.

Once you understand why you lie, you'll understand gravity. 

And earth is flat and space doesn't exist.

Elon Musk is a liar and a fraud, SpaceX is a hoax.

I'm not sure to what extent the frequency matters while "scanning" the universe though. If a civilization used a frequency that we dismiss as inconspicuous they could've slipped our attention while in plain sight.

And I agree with the notion that life is all around the universe. I am ~99% leaning towards believing that the universe is infinite in size and that there's any number of life out there. But in such a universe there's also going to be any number of civilizations that have yet to find any life other than them, as well as any number of civilizations that will either never find any life or simply be convinced that none exists.

Weren't we deliberately sending out signals to try and contact or attract the attention of aliens by the way? Although even in that case, I don't think it would be possible for us to cover the whole globe and to send a signal into all directions simultaneously, which has a compounding effect by distance travelled of the signal. The more I think about this the more absurd the idea of finding any civilization becomes. There seem to be a ton of factors that could make finding life extremely difficult even "close by".

When I said radio waves, I meant any kind of wave that can propagate long distances....  No matter how advanced your civilization is, you still need to use a wave that vibrates at a certain frequency.  We can detect that.

I don't know how a civilization could advance technologically without discovering waves... it is the basic means of long distance communication (except for quantum teleportation, which by theory is limited in the amount of information you can send instantly).

I agree with you that we have listened to only a small part of our galaxy.  But I believe if life formed here, it formed in a trillion other places around the universe.  Chances are one of those civilizations is within one hundred light years from us, so we could detect something in the small amount of time we have been listening.

That being said, if a civilization was even 200 years ahead of us, they would have moved past waves for communication (like we do now with fibre) and would be silent and invisible to us.   Chances are, if at least one civilization like this exists, they are a lot more than 200 years ahead of us. 

We could have intelligent neighbours less than a dozen years away, who communicate in the way our internet does - point to point.

We don't have to look everywhere, but as far as I'm aware we have looked virtually nowhere so far. I would also be cautious about assuming that radio waves would be used by such an advanced civilization. They could very well be using different frequencies. But that's overall an interesting point that I haven't really thought of yet.

What if we haven't found any other civilizations because they don't broadcast anything that we would search for into space? That combined with the tiny bit of universe that we have even attempted of exploring "in detail" so far further decreases the chances of finding anything.

At least first car in space is low pollution. Elon is madman genius. You can say what you want about him, but you have to agree - he has the style.

Why do we have to reach everywhere?  We only need to look nearby.  What if a civilization evolved a million years ahead of us (almost 100% probability when you look at the numbers) - they would be expanding and colonizing by now.  Why haven't we detected anything?

Possible answer:  Earth only broadcast into space for a little under a hundred years.  Now we are mostly digital - which does not send any radio waves into space.  If someone was looking for us, they would have to detect us in that timeframe.   So what are the chances we will detect another civilization via radio waves?

If humanity survives and goes out to the stars, I believe the first contact we will have with another life form is when we invade their planet with our colony vessels.  :/

And I was having such a nice conversation....

for me it was an amazing launch, the SpaceX Falcon Heavy rocket successfully launched its newest rocket, Falcon Heavy. This success made SpaceX the company that transformed the space rocket business. SpaceX is led by billionaire Elon Musk who is currently staying digadang as the owner of the company's strongest rocket operations in the world. The WorldX's First Space Challenge Rockets Successfully landed Falcon Heavy airs on Tuesday, February 6 at 3:45 pm local time from Kennedy Space Center, in Cape Carnaveral, Florida. By using recycled rocket boosters, SpaceX packages cost rocket costs so it's cheaper. Before SpaceX implemented this way, the rocket launch company used a disposable thruster that always changed every mission

I haven't studied astrophysics so I wouldn't know this. But that could be another potential reason for not seeing anybody around us.

That would require a civilization to actually have existed for a long enough time to be millions/billions of years ahead of us without having gone extinct. They would also have to exist in sufficient proximity of us.

Who knows how many galaxies (if any) are already partially or even fully colonized, but simply beyond our reach? We can only see as far as the light allows us to. And if the actual, rather than just the observable, universe is actually expanding faster than light that would make it virtually impossible to even attempt reaching some places. Given the potentially infinite size of the universe it seems potentially infinitely improbable for such a civilization not to exist in some place. But we know for fact that we haven't really seen shit yet. Maybe we got lucky and we're the first to get a shot, or maybe we're unlucky and just happened to be dropped in a place with nobody else close by.

Actually, that's faulty logic on my part....   First generation stars would have been created from nothing but Hydrogen and Helium.  There would be no planets.  The first generation stars would have created and distributed the heavy elements that form our planets and current sun via supernova.   So first generation stars could not have produced life.  :/

By that logic, the galaxy should be partly colonized already by civilizations that have been around longer than we have.  We're orbiting a second generation star, so every being that evolved under the first generation stars should be billions of years ahead of us in technology, right?

That would mean something like 2 million years at 50% the speed of light to get across. Let's be generous and overestimate to upwards of 10 million years to colonize whatever can be. That's virtually nothing compared to the time until a potential heat death, which may or may not even take place.

Without any means for teleportation/breaking the speed limit it would certainly require many generations of people to even get to every place that humans can settle in, but it's not impossible. And if humans don't get wiped out by themselves or some natural extinction kind of event, I don't see why we wouldn't end up colonizing the galaxy. In fact, it would seem inevitable to me if humans don't die out. Who knows if whatever reaches different places can still be called human though, the differences are bound to be quite drastic on those time scales. Communication would be pretty much nonexistant without superluminal transmission of information as well and a holiday trip across the galaxy won't be possible either, which makes the whole prospect at least as exciting as sobering.

As far as energy is concerned: https://ourworldindata.org/wp-content/uploads/2014/03/global-primary-energy-consumption-1800-2015-1.png
And we're still absolutely terrible at harnessing the energy output of the sun. Plus, if "uploading human consciousness" turns out to be possible, the amount of mass that would have to be sent through space could be drastically lowered. That would also allow for conscious travel, perhaps within a digital world. Although that would seem to make the whole endeavour redundant beyond climbing a mountain simply because it's there.
