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 nonsense.you 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.

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.
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.
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
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.
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!
To me, the attitude, or belief that Aliens are visiting this planet, or have at some time, is Human Egocentrism.
