🌌 Alien Megastructures and Dyson Spheres
A recent study suggests the possibility of advanced alien civilizations constructing megastructures around stars to harness energy. The concept dates back to 1960, with the idea that such structures, if they exist, would emit significant infrared radiation detectable from Earth. The researchers have identified seven stars with unusual infrared emissions without clear explanations, hinting at the potential presence of Dyson Spheres or other phenomena. The video features an astrophysicist and author who explains the concept of Dyson Spheres as a network of solar panels collecting energy from a star. While the existence of such structures is considered unlikely, the scientific community remains open to the possibility, acknowledging the need to explore natural causes for the observed infrared signatures, such as young stars with surrounding material or distant galaxies.
🤔 The Feasibility of Dyson Spheres
This paragraph delves into the discussion of whether Dyson Spheres could feasibly exist. The speaker, a professor of physics and astronomy, considers the idea unlikely but acknowledges the excitement and interest it sparks. He suggests that natural causes, such as young stars with material still coalescing or even planetary collisions, could account for the observed infrared emissions. The professor also highlights the vastness of the Milky Way galaxy, with potentially hundreds of billions to trillions of planets, indicating the possibility of life elsewhere. However, he raises concerns about the survival of civilizations long enough to advance to the point of constructing a Dyson Sphere, given the challenges humanity faces with climate change and nuclear issues.

Highlights
New study suggests the possibility of daily life in outer space through the identification of seven stars that may be surrounded by advanced alien mega structures.
The concept of alien mega structures is based on the idea that superior intelligent life might build large structures around their home stars to harness or reuse energy.
Physicist Freeman Dyson first proposed the idea of mega structures in 1960, theorizing that they could emit a lot of infrared radiation detectable from Earth.
Researchers have found seven sources glowing in the infrared without an obvious explanation, hinting at the potential for alien mega structures or other phenomena.
Astrophysicist and author of 'Black Hole Survival Guide' joins the discussion to provide expert insights on the topic.
Dyson spheres are explained as a concept where satellites or a network of solar panels could collect energy from a star.
The likelihood of the identified structures being Dyson spheres is considered very unlikely, but the idea remains exciting for scientists.
Natural causes for the infrared signature, such as young stars with surrounding material or distant galaxies, are considered more probable than Dyson spheres.
The possibility of planetary collisions as a natural explanation for the infrared glow is also discussed.
The scale of the Milky Way galaxy is highlighted, with potentially hundreds of billions or trillions of planets, suggesting the emergence of life could be inevitable elsewhere.
The discussion questions whether advanced civilizations capable of building a Dyson sphere could have survived long enough to do so, given current human challenges.
The feasibility of a Dyson sphere is deemed possible but unlikely, considering the precarious position of humanity since the Industrial Revolution.
Climate change and nuclear power struggles are cited as examples of the challenges that might prevent a species from surviving long enough to build such structures.
The era we are in is characterized by the belief that the emergence of life is possibly inevitable elsewhere in the universe.

NEW STUDY THAT COULD POINT TO A
POTENTIAL DAILY LIFE IN OUTER
SPACE.
A GROUP OF RESEARCHERS SAYS
THEY HAVE IDENTIFIED SEVEN
STARS THAT MIGHT BE SURROUNDED
BY SUPER ADVANCED ALIEN MEGA
STRUCTURES. I SAID ALIEN
STRUCTURES.
I KNOW YOU WHAT YOU WERE
THINKING, BUT STAY WITH ME.
THE BASIC IDEA IS THIS.
SUPERIOR INTELLIGENT LIFE MIGHT
BUILD BIG STRUCTURES AROUND
THEIR HOME STARS OR PLANETS AS
A WAY TO HARNESS OR REUSE
ENERGY.
IN 1960 PHYSICIST CAME UP WITH
THIS IDEA. IF THESE STRUCTURES EXISTED,
IF THESE STRUCTURES EXISTED,
THERE WILL BE SO MUCH ENERGY
THAT HUMAN SCIENTISTS ON EARTH
COULD SPOT IT BECAUSE IT WOULD
EMIT A LOT OF INFRARED
RADIATION.
RESEARCHERS SAY THEY FOUND
SEVEN SOURCES GLOWING IN THE
INFRARED, BUT COULD NOT FIND AN
OBVIOUS EXPLANATION FOR WHY THE SOURCES WERE GLOWING SO MUCH,
SOURCES WERE GLOWING SO MUCH,
WHICH COULD MEAN THEY ARE, OR
SOMETHING ELSE ENTIRELY.
WHAT I AM SAYING IS, WHAT?
SPACE IS SO CRAZY.
I WISH I UNDERSTOOD IT BETTER.
LET'S TALK TO A SCIENTIST TO
HELP GET OUR HEADS AROUND THIS.
I'M JOINED BY AN ASTROPHYSICIST
AND AUTHOR OF THE BOOK
BLACKHOLE SURVIVAL GUIDE, AS
WELL AS PROFESSOR OF PHYSICS
AND ASTRONOMY AT BERNARD
COLLEGE OF COLUMBIA UNIVERSITY.
PROFESSOR, THANK YOU SO MUCH
FOR BEING HERE.
I TRIED TO EXPLAIN IT A LITTLE
BIT.
THAT WAS MY DIRTY VERSION.
YOU HAVE A PHD IN PHYSICS FROM
MIT.
HOW DO YOU EXPLAIN DYSON
SPHERES?
>> THERE IS AN EXPLANATION.
IF YOU LOOK AT WHERE WE ARE.
WE ARE VERY FAR AWAY FROM THE
SUN.
IMAGINE THE LIGHT WE TRY TO
COLLECT WITH SOLAR PANELS TO
COLLECT THAT ENERGY.
IMAGINE IF YOU GOT REALLY CLOSE
AND CAUGHT EVERYTHING THE SUN
WAS EMITTING A TREMENDOUS
AMOUNT OF POWER.
DISON WAS THINKING ABOUT THIS.
HE WAS ORIGINALLY INSPIRED BY
SCI-FI WRITTEN BY DECADES EARLIER.
EARLIER.
HIS IDEA WASN'T SO MUCH A
SPHERE, IT WAS LIKE SATELLITES,
AND NETWORK OF THINGS ORBITING.
ESSENTIALLY, SOLAR PANELS
COLLECTING THAT ENERGY.
>> WHAT DO YOU MAKE OF THIS
STUDY? GENERALLY SPEAKING, IS A
GENERALLY SPEAKING, IS A
POSSIBLE THESE ARE DYSON
SPHERES?
>> IT IS VERY UNLIKELY, BUT WE
HAVE TO BE OPEN AS SCIENTISTS.
IF WE THINK WE KNOW THE ANSWER
BEFORE WE LOOK, WE ARE ALREADY
DEFEATED.
I THINK IT IS TERRIBLY
UNLIKELY, BUT IT IS EXTREMELY
EXCITING AND INTERESTING TO
THINK ABOUT.
WHAT IS PROBABLY GOING TO
HAPPEN IS WE WILL LOOK AT THIS
INFRARED SIGNATURE YOU
MENTIONED AND FIND OUT THERE IS A NATURAL CAUSE.
A NATURAL CAUSE.
A LOT OF THINGS MAKE HEAT. IT IS NOT THAT DISSIMILAR TO
IT IS NOT THAT DISSIMILAR TO
SEE THINGS EMITTING HEAT.
THE IDEA IS IF WE HAVE THIS
VERY TECHNOLOGICALLY ADVANCED
CIVILIZATION, THOUSANDS OF
YEARS BEYOND WHERE WE ARE RIGHT
NOW, AND THEY COULD BUILD SUCH
A THING THAT WOULD COLLECT ALL
THIS ENERGY, IT WOULD ALSO
COLLECT HEAT AND WE WOULD SEE
THAT INFRARED.
BUT THERE ARE OTHER NATURAL
POSSIBILITIES.
>> WHAT DO YOU THINK THOSE
COULD BE?
>> IT COULD BE A VERY YOUNG
STAR THE STILL HAS SOME
MATERIAL AROUND IT.
THAT IS HOW PLANETS FORM.
THEY COALESCE OUT OF THESE
EARLY DISCS.
THEY CAN EMIT INFRARED.
IT COULD BE THERE'S ACTUALLY AN
ENTIRE GALAXY IN THE DISTANCE
BEHIND THE STAR AND WE ARE
SEEING THAT.
COULD BE PLANETARY COLLISION.
THERE ARE NATURAL EXPLANATIONS. I THINK IT IS WORTH NOTING THAT
I THINK IT IS WORTH NOTING THAT
WE ARE WORKING JUST 1000 LIGHT
YEARS AROUND US.
A SOUNDBAR, BUT IT IS ACTUALLY
REALLY CLOSE.
THAT IS OUR BACKYARD.
THE ENTIRE MILKY WAY GALAXY IS
100,000 LIGHT-YEARS ACROSS.
THERE ARE PROBABLY MORE PLANETS
IN THE MILKY WAY GALAXY THEN
THERE ARE STARS.
WE'RE TALKING ABOUT HUNDREDS OF
BILLIONS, MAYBE TRILLIONS, OF
PLANETS OUT THERE.
I THINK WE'RE IN AN ERA WHERE
WE THINK EMERGENCE OF LIFE IS
POSSIBLY INEVITABLE ELSEWHERE.
WE ARE NOT THE ONLY EXAMPLE.
WHETHER OR NOT THEY SURVIVED
WITH THOUSANDS OF YEARS OF
ADVANCEMENTS TO BUILD A DYSON
SPHERE IS A DIFFERENT STORY.
>> DO YOU THINK THERE IS A
SCENARIO WHERE A DYSON SPHERE
MY ACTUALLY EXISTS?
OR IS THIS A SCI-FI FANTASY?
>> I THINK IT IS FEASIBLE,
UNLIKELY.
IF YOU LOOK AT WHERE WE ARE
SINCE THE INDUSTRIAL
REVOLUTION, JUST A COUPLE
HUNDRED YEARS.
WE ARE IN A PRECARIOUS PRODUCER
AND.
-- POSITION.
WE HAVE CLIMATE CHANGE,
STRUGGLES WITH NUCLEAR POWER,
NUCLEAR WEAPONS THAT COULD BE
DESTRUCTIVE.
IT IS UNCLEAR THAT ANY SPECIES
COULD SURVIVE FAR ENOUGH INTO THEIR OWN FUTURE TO BE ABLE TO
THEIR OWN FUTURE TO BE ABLE TO
BUILD A DYSON SPHERE.
BUT THERE ARE OPTIMISTS OUT
