If advanced aliens have to construct a sphere so big it can fit around an entire star just to get an unlimited power source, they're the worst advanced aliens ever. Don't bother looking for the dumb ones.

It’s just V’ger messing with us.
Meanwhile, is the supermassive all-consuming Sagittarius A* preparing to gobble up our galaxy? Or is it more like a rare Yellowstone geyser going off?
A supermassive black hole in the center of the Milky Way just woke up and is flashing 75 times brighter than ever observed, after being quiet for more than 20 years, baffling astronomers.
Sagittarius A*, a supermassive blackhole, is normally low key with minimal fluctuation in brightness. Recently, however, it bloomed 75 times brighter than ever before for no apparent reason.
The technical word is "hungrier" it seems.
https://phys.org/news/2019-09-black-hole-center-galaxy-hungrier.htmlWhat if all these different galaxies are just co-existing different outcomes of the quantum events of the early universe? What if every quantum event produces multiple new realities and this is what causes the universe to expand???
Someone who smoke weed should ponder that.
In our vast universe, the heaviest black holes grew from seeds. Nourished by the gas and dust they consume, or by merging with other dense objects, these seeds grow in size and heft to form the centers of galaxies, such as our own Milky Way. But unlike in the realm of plants, the seeds of giant black holes must have been black holes, too. And no one has ever found these seeds — yet.
And this is why we don't see any aliens in the heavens. We're still chimps who haven't got past our own moon and we're about to start 'ripping holes in the fabric of reality'.
And it will be the same for any other alien civilization that reaches our level (an advanced tech civilization).

They don't! That's why we should be looking for smoke signals in outer space, not radio signals.
But seriously, our own galaxy, let alone the universe, is so vast that any advanced aliens would have already long since found us before we ever find them. We're like primitives stranded on a desert island, and we're looking for messages floating around in bottles like that's how the civilized world communicates. Then one day a big warship floats up and kills us all with its guns and turns the island into a rubber tree plantation.
Earth's fate would be like that if the aliens found us, but the fact there's so many planets out there, and there's been so much time already, pretty much shows advanced aliens don't exist.
Yep. The so called Great Filter idea. Question however, is whether the filter is before or after us.
If they aren't deliberately hiding anyway or somehow invisible to us.

This makes no sense. If Advanced Aliens noted our solar system and they came to harvest it for energy, why would they care out a useless rock orbiting it? We think Planet Earth has valuable minerals, etc., but for an Advanced Civilization it's all in terms of Energy. The Sun has it in spades, Planet Earth doesn't. Maybe one of their Black Holes would eat the Sun, leaving Planet Earth adrift.
Planet X might just be a bowling-ball-sized black hole
An astronomical anomaly considered by scientists to point to an as-yet-undiscovered planet may actually be a big black hole lurking deep within our solar system, according to a new theory.
Mathematical evidence for a planet, dubbed Planet Nine or Planet X by space scientists, was revealed by Caltech researchers in 2015. The strange object, they said, could have a mass some 10 times that of Earth and take up to 20,000 Earth years to complete one orbit of the Sun as it sits between 45 billion and 150 billion kilometers from our star.
However, now two physicists are suggesting that the enigmatic ‘Planet X’ isn’t a planet at all, but a planet-mass black hole, sucking in matter from its surroundings. If they’re correct, they say they will be able to find supporting evidence in the form of flashes of gamma rays, created by the interactions between dark matter particles in the halo surrounding a black hole.
And not only that, but the pair say in a paper on their theory that a black hole matching the projected mass of Planet X would be so dense it could be only the size of a bowling ball.
The researchers argue that focusing studies on the supposition that it’s a planet that’s out there seriously hampers the potential for making new discoveries.

Is Earth under the watchful eye of “lurking” extraterrestrial spy probes? One US physicist says it wouldn’t hurt to send out probes of our own to take a look and see. Physicist and independent SETI (Search for Extraterrestrial Intelligence) researcher James Benford posited that nearby asteroids that track with Earth’s orbit – also known as co-orbitals – would make the ideal place for an otherworldly spy post. He published his findings, titled “Looking for Lurkers,” in the peer-reviewed Astronomical Journal last month.
“A probe located nearby could bide its time while our civilisation developed technology that could find it, and, once contacted, could undertake a conversation in real time."
Benford not only offers “possible sites for extraterrestrial probes,” but suggests ways researchers might look for evidence of the alien tech, ranging from using optical and radio telescopes to sending a spacecraft outright.
Given its close and constant presence near Earth, one might think the moon would make a better spy station than more distant co-orbitals, but Benford said any particular section of the moon’s surface is “in darkness for two weeks at a time,” depriving any probe of the solar energy it might need to function. Placing the probes too close to Earth might also pose a problem, as Benford argues the ETs would likely wish to remain undetected.
The closest co-orbital asteroid appears to be in a stable orbit that will track with Earth for centuries. While there is still much to be learned about the bodies, Benford said they would make a good vantage point for an alien probe if they held steady orbits over long periods of time.
Benford says there is nothing to lose in taking a look, and only new knowledge to gain. “If we don't find anything, that means no one has come to look at the life of Earth for over billions of years,” Benford said. “That is a big surprise, a stunning thing.”
Paul Davies, a physicist and astrobiologist at Arizona State University, said it would be beneficial for Science. "... it costs very little to go take a look, why not? Even if we don't find E.T., we might find something of interest.”

“It will start a whole new line of thinking. I don’t think we’re prepared for the results."
As we humble earthlings begin to learn more about the universe and potentially stand on the cusp of great discoveries about the planet Mars, we may not be prepared for what’s in store of us, warns the chief scientist of U.S. space agency NASA.
Dr. Jim Green believes that as two rovers from NASA and the European Space Agency (ESA) prepare to embark for Mars next summer, humanity could be overwhelmed by the implications of studies to come.
If scientists find biosignatures of life in Mars’ crust, a new era of astrobiology could begin.
“What happens next is a whole new set of scientific questions. Is that life like us? How are we related? Can life move from planet-to-planet or do we have a spark and just the right environment and that spark generates life – like us or not like us – based on the chemical environment that it is in?”

Earth has life on it, and the advanced aliens need the DNA because are hopelessly inbred, like European royalty. That's why they're traveling the galaxy. If all they needed was energy, they'd just be hitting up their abundant local brown dwarfs.
The tabloids have it right that they would most likely already be here if they exist at all, hiding in the background, manipulating us in utter impunity.
"Advanced Aliens" that can't manipulate and are dependent on Dna?

When thinking about the possibility of life in the universe, it is also important to remember that we have to be open to the idea that this life has no direct connection to life as we know it. We are imagining alien life with our own planet as a frame of reference. We think of living things like they live on Earth. We think of communicating like we communicate on Earth. We think of evolution as it pertains to our own evolution. We have to consider that there may be nothing similar to what we know and consider the possibility that the life in the universe may be so different than ours that we cannot comprehend it.
You ever read the book, "Solaris"?

The real-world effects of a genetic mutation are too complex and iffy to predict, no matter how advanced. It is easier and more effective just to have DNA farms everywhere. They set up a planet with the conditions they want to develop genes for, wait a while, and then go back and harvest the genes. That's why they're periodically dropping by and sticking probes in people.
A team of Russian scientists is developing a donut-shaped spaceship that can reach the farthest corners of the solar system in record time by taking power directly from the Sun.
The spaceship’s clever method of sourcing fuel will allow it to overtake even the fastest probes, unravel questions about the origin of comets, and even provide electricity to future martian colonists, all while proving Albert Einstein’s theory of general relativity.
The plate covering the middle part of the bagel-shaped ship is a solar sail. It is coated in a special substance that will begin to evaporate as it approaches the Sun, giving the ship a boost of jet acceleration without having to carry heavy engines.
Using the pressure of sunlight in this ingenious manner will allow the sailboat to speedily get to the mysterious Oort cloud at the edge of the solar system, where it’s believed that comets are born.
The duration of flights to other stars is gigantic. The Voyager 1 high-speed space probe will take 300 years to reach the Oort cloud. Our sail can reach it in 20-30 years, said Professor Olga Starinova, of Samara University’s Department of Space Engineering. This means that we or the next generation will be able to obtain evidence of existence clouds, presumably generating all comets, and examine what remains of the formation of the solar system about 4.6 billion years ago, she explained.
The highly advanced technology will also make it possible to prove fundamental laws of physics, such as Einstein’s famous theory, that cannot be achieved under Earth’s conditions. It will also be able to “warm” Mars by reflecting the Sun’s rays, helping to enable the colonization of the Red Planet.
