Hello friends my name is satyam Rastogi and you all know Dyson sphere is a very exciting topic
Kepler 452 is a bright star and there are tabby stars , both stars can be of same size but tabby star is very dim
Tabby star may be of same distance from earth like Kepler 452 but it looks very dim do you ever thinked why it is so
Now as you know scientists are in search of this amazing discoveries in the universe so to find out the secrets of universe
There is a very popular theory that if in universe there is a very advanced civilisation it can make Dyson sphere to utilise its star power for its advancement and growth, so may be this is the real reason of a tabby star
A Dyson sphere is a megastructure that surrounds a star and captures its energy. While it’s theoretically possible to build a Dyson sphere, it’s currently beyond humanity’s engineering capabilities
Here are some reasons why building a Dyson sphere is currently impossible:
- Resources Even if all the matter in the solar system were used, it wouldn’t be enough to build a Dyson sphere around the sun.
- Technology The construction of a Dyson sphere would require an enormous amount of resources and technological capabilities far beyond our current level.
- Industrial capabilities The number of craft required to obtain, transmit, and maintain a complete Dyson sphere exceeds present-day industrial capabilities.
However, some say that given enough incentive, resources, and technological advancement, Dyson spheres are possible.
Some say that it’s theoretically possible to build a partial Dyson structure, such as a Dyson Swarm, using materials from asteroids, moons, and other celestial bodies in the solar system.
Although Dyson sphere systems are theoretically possible, building a stable megastructure around the Sun is currently far beyond humanity’s engineering capacity. The number of craft required to obtain, transmit, and maintain a complete Dyson sphere exceeds present-day industrial capabilities
According to the Kardashev Scale, a civilization that can build a Dyson sphere is a Type II civilization. The Kardashev Scale is a way to measure a civilization’s technological advancement by the amount of energy it can harness. A Type II civilization can harness the energy of its entire star, which could be achieved by building a Dyson sphere.
Here are some other types of civilizations on the Kardashev Scale:
- Type I: Controls the resources of a planet
- Type III: Controls the resources of a galaxy
- Type 41.0: Extremely advanced civilizations that can control one existence
A Type 0.9 civilization is a democratic-capitalist civilization that is spreading across the world through democratic movements and free trade agreements. It is a nearly planetary-scale civilization, and is hundreds or thousands of times more advanced than ours.
According to the Kardashev Scale, a Type 0.9 civilization has a power consumption of 1015 W to 1016 W. During this “Expedition Age”, space-based solar power prototypes face challenges from space debris, and a global clean-up is initiated with the backing of world governments
According to Edge.org, a Type 0.8 civilization is a liberal democracy that gives the vote to all citizens and has markets that embrace free trade.
According to Carl Sagan’s interpolated Kardashev scale, a Type 0.8 civilization would use 100 trillion watts of energy on average. However, humanity currently only uses 18.87 trillion watts on average.
According to AQI, many scientists currently consider human civilization to be between 0.7 and 0.8 on the Kardashev scale
Today, we are at 0.7 as we prepare to build a permanent presence on our nearest celestial neighbour. Once we master fusion energy and have quantum computing go mainstream we will move to 0.8 which should happen before 2100. Kardashev’s scale aligned with the amount of energy civilizations consume
According to Quora, it’s unlikely that humanity will reach a Type 0.8 civilization before 2110. However, 21stcentech.com says that humanity will reach a Type 0.8 civilization before 2100, once we master fusion energy and quantum computing becomes mainstream.
According to NASA scientists, humanity won’t become a Type 1 civilization until around 2371. This is because humanity will need to increase its energy production by over 100,000 times
Kardashev’s classification is based on the assumption of a growth rate of 1% per year. Kardashev believed that it would take humanity 3,200 years to reach Type II, and 5,800 years to reach Type III
Some astronomers have speculated that the objects eclipsing Tabby’s Star could be parts of a megastructure made by an alien civilization
Some astronomers have speculated that the objects eclipsing Tabby’s Star could be parts of a megastructure made by an alien civilization. A megastructure is a very large artificial object, and some astronomers have suggested that the star is surrounded by a Dyson sphere. A Dyson sphere is a hypothetical megastructure that an advanced civilization might build around a star to intercept some of its light for their energy needs
However, an analysis by more than 200 astronomers published in 2018 shows that the mysterious dimming of star KIC 8462852 is not being produced by an alien megastructure. Instead, scientists have ruled out the presence of an alien “megastructure” around KIC 8462852, and instead believe that any objects surrounding the star would be no bigger than a grain of dust.
Some other explanations for the dimming of Tabby’s Star include:
- Dust A new study suggests that the long-term dimming of Tabby’s star is likely caused by dust, not a giant network of solar panels or any other “megastructure” built by advanced aliens.
- Stellar indigestion Another explanation is that the dust could be the result of a case of stellar indigestion. If a gas giant planet were devoured by this star, it could be the culprit.
- Tilted ring structure A tilted ring structure could explain the dimming effects detected from Tabby’s Star in the past.
Tabby’s Star, also known as KIC 8462852, is a star that has gained attention due to its unusual light fluctuations. The star’s light has dimmed by up to 22%, and the fluctuations can’t be easily explained by natural phenomena.
The star’s unusual dimming sparked a surge of public interest. Citizen scientists discovered the star’s unusual light fluctuations using data from the Kepler space telescope. The star’s discoverer, Tabetha Boyajian, nicknamed it “Tabby’s Star”.
The star’s light is strange, with abrupt dimmings. Over a period of about four years, observations from the Kepler mission revealed ten dips in brightness, ranging from 0.5% up to 20%. Analysis of astronomical photographs in the archive of Harvard Observatory show a 15% dimming of Tabby’s star between 1890 and 1989.
Here are some other hypotheses for Tabby’s Star:
- Planet swallowing In 2016, researchers suggested that the star swallowed a planet, causing a temporary increase in brightness.
- Ringed planet A hypothesis suggests a ringed planet and many asteroids.
- Melting exomoon A unique hypothesis suggests that a planet and moon moved closer to the star and were destroyed.
- Comet swarm Scientists have hypothesized that the star’s dimming could be caused by hundreds of comets passing in front of it.
- Disrupted exomoon In 2019, astronomers reported that the dimmings may have been caused by fragments from a disrupted exomoon.
The Dyson sphere is a hypothetical megastructure that surrounds a star and captures a large portion of its solar power output. In Star Trek, the Dyson sphere is a shell of solar panels that surrounds a star. The sphere’s inner surface is 550 million times larger than Earth’s surface and can intercept almost all of the Sun’s energy
The Dyson sphere appears in the Star Trek: The Next Generation episode “Relics”. In this episode, the Dyson sphere is 200 million kilometers in diameter and has a volume of 4.19*10^24 km^3. The sphere’s inner surface is 12510^15 km^2, which is 25010^6 times the surface of Earth
The Dyson sphere appears in the 1992 Star Trek: The Next Generation episode “Relics”. In this episode, the Enterprise discovers a Dyson sphere with a crashed ship on its surface. An away team finds some systems still powered up and the chief engineer from the old Enterprise, Montgomery Scott
The Dyson sphere also appears in the Star Trek: The Next Generation episode “A Step Between Stars“. In this episode, the player character and Tuvok rediscover the Jenolan sphere and the ship studying it.
The Dyson sphere also appears in Season 6, Episode 4 of Star Trek: The Next Generation. In this episode, the crew needs the help of someone who has survived for 75 years to escape the Dyson sphere
The interior of a Dyson sphere would absorb the star’s energy output, allowing lifeforms to live on the interior surface almost indefinitely. The sphere would create immense living space, but also gather extraordinary amounts of energy
The surface area of a Dyson sphere can be estimated using the formula 4πr^2, where r is the radius of the sphere.
For example, a Dyson sphere with a radius of 150 million kilometers (the Earth-Sun distance) has an interior surface area of 2.83 × 1017 square kilometers (283,000 trillion square kilometers).
A Dyson sphere built at 93 million miles from the sun, the same distance as Earth, would contain about 600 million times the surface area of our planet in its interior. However, comparatively little of the surface would be habitable on account of a lack of gravity
Astronomer Freeman Dyson first proposed the Dyson sphere in 1959. While it’s theoretically possible, building a stable Dyson sphere around the sun is currently beyond humanity’s engineering capabilities.
Some say Dyson spheres are impossible for technological reasons. For example, it’s not possible to build a Dyson sphere strong enough to support itself against the sun’s gravity. Radiation pressure from the star inside would likely also explode it.
Some astronomers are now looking for signs of Dyson spheres around particular stars. In 2014, NASA’s Kepler spacecraft discovered a second “Dyson sphere” star.
If a Dyson sphere were built around the sun, it would likely appear as a continuous, solid shell from Earth. However, it’s more likely that a Dyson sphere would consist of a collection of orbiting solar panels that only partially cover the star
From inside a Dyson sphere, the sky would appear blue with a motionless sun, creating a permanent midday. The sphere would be sufficiently big that it would appear locally flat, though curvature at the “horizon” might be noticeable from high enough above “ground level
