The biggest supercluster known in the universe is the Hercules-Corona Borealis Great Wall. It was first reported in 2013 and has been studied several times. It’s so big that light takes about 10 billion years to move across the structure. For perspective, the universe is only 13.8 billion years old.
What is the biggest object in the universe?
The largest known structure in the Universe is called the ‘Hercules-Corona Borealis Great Wall’, discovered in November 2013. This object is a galactic filament, a vast group of galaxies bound together by gravity, about 10 billion light-years away.
What is bigger than a galaxy?
Superclusters form massive structures of galaxies, called “filaments”, “supercluster complexes”, “walls” or “sheets”, that may span between several hundred million light-years to 10 billion light-years, covering more than 5% of the observable universe.
What is the most dangerous thing in the universe?
Supermassive black holes are strange. The biggest black hole discovered so far weighs in at 40 billion times the mass of the Sun, or 20 times the size of the solar system. Whereas the outer planets in our solar system orbit once in 250 years, this much more massive object spins once every three months.
What is the smallest thing in the universe?
The electron is, as far as we know, one of the fundamental, indivisible building blocks of the universe. It was the first Standard Model particle ever discovered. Electrons are bound to an atom’s nucleus by electromagnetism.
What galaxy do we live in?
The Milky Way is a large barred spiral galaxy. All the stars we see in the night sky are in our own Milky Way Galaxy. Our galaxy is called the Milky Way because it appears as a milky band of light in the sky when you see it in a really dark area.
Why is the universe so big?
Despite what you might assume from this image, most of the Universe is empty, intergalactic space. But the reason the Universe is this large today is because it’s expanded and cooled to reach this point. Even today, the Universe continues to expand at a tremendous rate: approximately 70 km/s/Mpc.
What are the most powerful things in the universe?
Quasars inhabit the centers of active galaxies and are among the most luminous, powerful, and energetic objects known in the universe, emitting up to a thousand times the energy output of the Milky Way, which contains 200–400 billion stars.

A: “The most beautiful thing in the universe is the human ability to comprehend it. “Our universe is extraordinarily complex, with processes occurring on all scales, from the subatomic world to the universe at large.
What is the coldest thing in the universe?
It is also known as the Bow Tie Nebula and catalogued as LEDA3074547. The nebula’s temperature is measured at 1 K (−272.15 °C; −457.87 °F) making it the coldest natural place currently known in the Universe. The Boomerang Nebula is believed to be a star system evolving toward the planetary nebula phase.
What is inside a neutron?
A neutron contains two down quarks with charge −1⁄3 e and one up quark with charge +2⁄3 e. Like protons, the quarks of the neutron are held together by the strong force, mediated by gluons. The nuclear force results from secondary effects of the more fundamental strong force.
What is inside a Preon?
In particle physics, preons are point particles, conceived of as sub-components of quarks and leptons. … Each of the preon models postulates a set of fewer fundamental particles than those of the Standard Model, together with the rules governing how those fundamental particles combine and interact.
What is the smallest thing in the human body?
Conveniently, that would be the stapes. It is one of three tiny bones in the middle ear that convey sound from the outer ear to the inner ear. Collectively called the ossicles, these bones are individually known as the malleus, incus, and stapes.
