How Advanced Alien Civilizations Would Conquer the Galaxy

Ancient extraterrestrial civilizations, millions of years older than humanity, would need enormous amounts of energy. By creating a swarm of satellites in a spherical shell, they could harness much of the power of their star.

Science fiction author Olaf Stapledon described spherical, energy-trapping alien structures in his 1937 novel "Star Maker":

"Not only was every solar system now surrounded by a gauze of light traps, which focused the escaping solar energy for intelligent use, so that the whole galaxy was dimmed, but many stars that were not suited to be suns were disintegrated, and rifled of their prodigious stores of sub-atomic energy."

Th Concept of Dyson Spheres is nothing new to many of us. I read this earlier and honestly didn't think anything new was presented, then it dawned on me, Since many well known scientists/theoretical physicists and respected mathematicians openly discuss the concept of Dyson Spheres. Are there ANY present programs/probes actively searching for either these spheres outright or for sings of the existence?

Seems that if this is a viable possibility how would they know if they are looking at one or something that is assumed to be a Rocky Giant? How would one even look? IF an Alien Civ has completely surrounded their Star or solar System would that even be possible to spot with our present level of Tech?

To be honest the first time I heard of these Spheres was in a Star Trek episode. It fascinated me. For the less than familiar with the concept.

I'd like to leave you with the following video.

The Fermi Paradox...

Talk by Stuart Armstrong, at the Oxford physics department

Abstract: The Fermi paradox is the contrast between the high estimate of the likelihood of extraterritorial civilizations, and the lack of visible evidence of them. But what sort of evidence should we expect to see? This is what exploratory engineering can tell us, giving us estimates of what kind of cosmic structures are plausibly constructable by advanced civilizations, and what traces they would leave. Based on our current knowledge, it seems that it would be easy for such a civilization to rapidly occupy vast swathes of the universe in a visible fashion. There are game-theoretic reasons to suppose that they would do so. This leads to a worsening of the Fermi paradox, reducing the likelihood of "advanced but unseen" civilizations, even in other galaxies.

edit on 8-2-2014 by SLAYER69 because: (no reason given)

this is just total cannot defy the laws of economics or resources

where are they going to get the MATERIAL for this giant humongous sphere?

have you even bothered to calculate the volume?

not enough material if even if you crush jupiter and all the planets in the solar system and most of that is GAS GAS GAS.


Thats why the tech for this would be millions of years more advanced than us they would literally have to tear down solar systems always found this option unlikely. Used to think the von neumann probes were an option until you think. If any advanced race unleashed self replicating probes in the galaxy its just suicide. Because within a couple of million years they could consume everything. If there were an intergalactic council this would be the first thing banned.

So in around 200 years are we goin to have interstellar fligh?

I am less optimistic about your difference in technology when our best efforts so far has been a bus in low orbit and 3 people trips to the moon for a week, it may look similar but it's far from it.

Consider, if you will, for instance, the Alcubierre Drive.

The Alcubierre drive or Alcubierre metric (referring to metric tensor) is a speculative idea based on a solution of Einstein's field equations in general relativity as proposed by theoretical physicist Miguel Alcubierre, by which a spacecraft could achieve faster-than-light travel if a configurable energy-density field lower than that of vacuum (i.e. negative mass) could be created. Rather than exceeding the speed of light within its local frame of reference, a spacecraft would traverse distances by contracting space in front of it and expanding space behind it, resulting in effective faster-than-light travel.

In basic layman's terms, it's Warp Drive, where one creates a local bubble around a craft, and warps space around it, so, locally, the spacecraft never exceeds the speed of light, and may not even move at all in the local frame of reference inside the bubble, but, the bubble itself via warping space could travel multiples the speed of light.

You could essentially go 1000 times the speed of light.
... or more.

This is real science.

This is real science currently being tested by NASA.

Introducing: Harold G. White (NASA)

Harold White became popular when he began publishing proposals to build a prototype of an Alcubierre drive.

In 2011, he released a paper named Warp Field Mechanics 101 that outlined an updated concept of Miguel Alcubierre's faster-than-light propulsion concept and methods to prove the feasibility of the project. Alcubierre's concept had been considered infeasible because it required far too much power than any viable energy source could produce.
White re-calculated the Alcubierre concept and proposed that if the warp bubble around a spacecraft were shaped like a "doughnut", it would be much more energy efficient and make the concept feasible.
White has stated that Warp Travel has not yet seen a "Chicago Pile-1" experiment, a reference to the very first nuclear reactor ever built that paved the way for nuclear energy.

To prove the feasibility of a warp drive, White and his team have designed a warp field inferometer test bed that can demonstrate a warp field phenomenon. The experiments will take place at NASA's Advanced Propulsion Physics Laboratory: Eagleworks at the Johnson Space Center.
A modified Michelson interferometer will allow the Eagleworks team to detect small changes in space-time and observe a potential warp field effect.

The devices used in the experiment will need to directly generate negative vacuum energy

Granted, there's a whole host of problems and questions with this that need working out. Generating Negative Vacuum Energy is not the least of them.

Still, this is being researched and funded RIGHT NOW, not some far off ambiguous sometime in the maybe future, but right now.

How long will it take White's team to show progress in the proof of concept testing of this?
I don't know.
It might be several years.
Still, 200 years from now?
With research like this happening now, current, I've a fair degree of confidence that regardless of whether this current research shows positive results or not, 200 years is a fair enough tick to work out any issues, or advance currently unknown solutions.

For instance, what if we could quite very simply teleport across tens or hundreds of thousands of light years where issues of Mass and Volume aren't much concern such we could hollow out whole asteroids in the 200km range, give them some spin for artificial gravity on the inside wall, turn them into micro-Earths, capable of housing Millions of people, and then just teleport these micro-Earths all over the galaxy?

Sure, that's quite the bit of science fiction. Still, it's fun to think about and exciting should the Warp Drive actually prove feasible.

With breakthroughs in age reversal technologies also making progress, we, all of us living right now under the age of ... 40 - 50, even into the 60s, could very well live another 200 years, in person, and see these things happen, if they wanted.

With research into whats known as exotic matter let us just say people will be amazed with the possibilities.

Okay... so. We are going to have the capability to travel the stars in a couple of centuries...


People are unwilling to contemplate that some advance alien lifeforms elsewhere in the universe has already achieved this, traveled here and begun their own scientific surveillance of us.

That's delicious irony.

To me, the attitude, or belief that Aliens are visiting this planet, or have at some time, is Human Egocentrism.
Culturally, we think we're some kind of special, that we're significant.
The primary religious mythologies currently observed place us at the center of creation; so super special that we're the mirror image of 'god'.

In reality, we're just another animal in a long line of animals were 99.9% of all the life that's ever existed on this planet since life first started is Extinct.

Because we're clever enough to contemplate ourselves, we fall into the trap in thinking we're so significant that we actually merit Alien visitation.

Thing is, the very thing that gives high probability for the potential existence of intelligent technological life elsewhere in the vast ambiguity of the Universe is the very thing that makes it quite unlikely that we're being visited, or have ever been.

The universe is quite massively large, and also extensively old, where Earth, with humans on it, is a single grain of sand out of 100,000 beaches at 4:00pm on Tuesday for only one hour, over the course of a Million years.

Even if you knew for a fact there was an Earth and that it'd have humans on it at 4:00pm on a Tuesday some time after a Million years, and it was a single grain of sand out of 100,000 beaches, and you started actively searching for it, what' the possibility you'd find that single grain of sand, out of 100,000 beaches, and what's the chance you'd find it during that one single hour starting at 4:00pm on Tuesday, out of a Million years?

Sure, there's very likely life and even intelligent technological life out there ... somewhere.
There's likely plenty of dead civilizations too, where only the husks and foundations of buildings and scattered artifacts remain.

There could actually be BILLIONS of galactic spanning civilizations all over the Universe, and not one single civilization out of those Billions be aware of even one single other, and those are galactic spanning civilizations.
Here, we're just a singular insignificant mote of dust compared to entire galactic spanning civilizations.
We're so tiny, and, we've only been around since 4:00pm on Tuesday for an hour.

It's really quite unlikely.
Further, there's no good evidence.

Thus, we look for Dyson structures occulting stellar bodies in hopes of finding some sign that would indicate there's someone else out there because, it'd be much easier for us to detect someone capable of such grand engineering than anyone detecting us.
We're just one little planet.

There could therefore have been space faring civilizations that were flitting between star systems even before the birth of our Solar System! If we have achieved space flight in a short span of a little more than hundred years from the Wright brothers first heavier than air flight, think what advanced cultures would have achieved in a billion years!

We still ride bicycles.

I don't know we go to the zoo, if aliens are so advance that they can travel as you say, maybe this is the closest zoo to them, lets go see the humans daddy lets see how they build their ugly nest

i think we are entering the last few billions of years of this universe and that being said most of the other technic civs have either died out or transended physical instamentality and our universe now is populated by the leftovers of other civilzations attempts to seed the rest of the universe, and thats why we live in the cosmic BFE of our galaxy. This is just what i think, but hey if we ever do meet another technic civ, i hope they are peacegul because if they are not, we are screwed.
