A Dyson Sphere is built around a star, not too close, of course. Just enough so that much of the star's energy can be captured/harnessed.This is a Dyson sphere...Or the theoretical model of one.Some believe that the major Type 2 civilizations on the Kardashev scale they own one.Thus obtaining all the energy they will ever need, from their star.Some models of Dyson spheres are intended to almost completely enclose the star, so that every iota of its emitted energy could be obtained.That, in theory, would give us something like 400 septillion watts of power. Per second, of course. Which is on the order of a trillion times more energy than our current global consumption.But according to Stuart Armstrong of the University of Oxford, building a Dyson Sphere that completely encloses a star is not feasible. Because the tensile strength, necessary to prevent the sphere from breaking, completely exceeds that of any known material.Estimates for a Dyson Sphere like the one I showed you in the picture put the resource materials needed somewhere around 1.82E + 26 Kg. That's 182 septillion tons of materials. The number may vary, of course, depending on the density of the materials used.Some have even asked here on Quora, if we could currently build one. And the answer is, of course, no. We do not possess the proper propulsion technology, resource harvesting technology, or space survival technology necessary for such an undertaking.With current technology, it would take something like 120 billion years to build a Dyson Sphere around our star.
this is a cross over i really wanted to be made but sadly no one did and this will be the first time i ever to show this amazing crossover idea side note for everyone: im using an hh oc for the witch because i had a hard time choosing a character for the witch

a tamaki souh fanfictionback and forth text messages between two [text] best friends
A genius youth, with his martial spirit yet to awaken, his cultivation stagnant, and enduring constant bullying from others. Fortunately, he obtained the White Dragon Jade Pendant, awakening the supreme Dragon Soul within him. From that moment, he embarked on the path of defying the heavens.Emperors' proud offspring, legendary heroes, and invincible legends, what do they matter? If anyone dares to oppose me, I can suppress them with a mere flip of my hand. If the heavens favor me, all is well; if the heavens oppose me, I dare to split the sky itself!
One day, the universe was split into two realms. Reality and fantasy were soon separated by a dimensional barrier with many mythical creatures migrating towards the Realm of Fantasy. Within these creatures rests the mighty dragon race, which quickly became the dominant species with their vast elemental prowess. A power that could devastate the very planet itself with ease. Humans wished to capitalize on such mighty strength, and soon, a bond was forged between the two species...and yet there are those who wish to threaten the realm. Heroes were formed, and together, they pushed back against the darkness for millenniums! But one day...tradition shattered and the heroes began to fall one by one... Centuries later, a 27 year old man from Earth was brought into the Realm of Fantasy by a rather rude goddess! The boy was quickly sent to the new world, one that was clearly above his paygrade! Left with no choice, the boy soon needed to find a way to survive in this world. Meeting new friends and allies along the way...while the lurking darkness watched from the abyss...- Story by SageAuthor's Note - Upload Schedule is Every Wednesday at 3:00 pm EST.
