Have Scientists found Dyson Sphere Under Construction?

In order to explore the idea that such a structure could have been built by intelligent alien life, the Extraterrestrial Intelligence Institute, Seti, trained its Allen Telescope Array on the star for more than two weeks.
Experts looked for two types of radio signal: narrow-band signals generated as a 'hailing signal' for alien societies wanting to announce their presence, and broad-band signals.
These signals would be produced by 'beamed propulsion'.
Seti said that if large scale alien engineering projects really are underway, the array would pick up signals made by intense microwave beams that could be used to power spacecraft.
Scientists analysing the data found no clear evidence for either type of signal.
They believe this rules out the presence of omnidirectional transmitters - large antenna - of approximately 100 times today's total terrestrial energy usage in the case of the narrow-band signals, and ten million times that usage for broad band emissions.
So the presence of a Dyson sphere is unlikely.

Im not saying that its aliens but that reasoning is short sighted as frick. If a civilization can build a dyson sphere, Id say they are communicating in a similarly advanced way

I'm sure their propulsion systems and communications are beyond our comprehension at this point. Saying 0 chance is extremely ignorant.

This could also be a long abandoned, non functioning Dyson Sphere that was built by an alien race that no longer exists.

The only way any aliens would know how far advanced we are is to get really, really close to pick up our radio waves that have gone out into space. Hypothetical if they could see our planet from a far distance they would be looking at humans poking mammoths with sticks, or similar.

Exactly

It's statistically impossible for there not to be intelligent life either out there, previously out there but currently extinct, or evolving now. I think it's pretty safe to say that life has been created millions of times universe wide. Most of it has come and gone it the last 14 billion years. Others may be just popping up in a fashion such as earth in the last billion years or so. Only a small fraction of the total exists at any one time.

With that said, unless a warp drive is developed and time dilation is resolved we'll never find each other. Is it possible to develop it.... Who knows. Physics says it's possible, but is it possible by humans is the better question.

A Dyson Sphere may be impossible even for an advanced civilization. However, a Dyson Swarm may be possible and might have the same effect on the star's light.

Okay, so the fanciful Dyson Sphere appears to defy the laws of physics. A related concept—the Dyson Swarm—is more promising. "The Swarm is the more realistic model," Armstrong says.

A Dyson Swarm consists of thousands of relatively small mirrors or solar panels in an array of orbits around the sun. Like a dense cloud of bees buzzing around a hive, a Dyson Swarm largely shrouds the sun from external view, capturing most of the available solar energy.

I thought this was a vacuum related thread. Then I realized it was about space.
