The largest known ‘object’ in the Universe is the Hercules-Corona Borealis Great Wall. This is a ‘galactic filament’, a vast cluster of galaxies bound together by gravity, and it’s estimated to be about 10 billion light-years across!

What is the biggest secret of the universe?
Dark Energy: The Biggest Mystery in the Universe.
What is the most dangerous thing in the universe?
Why black holes are the scariest things in the universe. For one, falling into a black hole is easily the worst way to die. Halloween is a time to be haunted by ghosts, goblins and ghouls, but nothing in the universe is scarier than a black hole.
Why is Planck length smallest possible?
So why is the Planck length thought to be the smallest possible length? The simple summary of Mead’s answer is that it is impossible, using the known laws of quantum mechanics and the known behavior of gravity, to determine a position to a precision smaller than the Planck length.
What is the most beautiful thing in the universe?
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 are 3 things found in the universe?
The Universe is thought to consist of three types of substance: normal matter, ‘dark matter’ and ‘dark energy’. Normal matter consists of the atoms that make up stars, planets, human beings and every other visible object in the Universe.
What is inside of a quark?
A quark is a tiny particle which makes up protons and neutrons. Atoms are made of protons, neutrons and electrons. The flavours are up, down, strange, charm, top, and bottom. Up, charm and top quarks have a charge of +2⁄3, while down, strange and bottom quarks have a charge of -1⁄3.
Who has created God?
Defenders of religion have countered that the question is improper: We ask, “If all things have a creator, then who created God?” Actually, only created things have a creator, so it’s improper to lump God with his creation. God has revealed himself to us in the Bible as having always existed.
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.
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.
What’s bigger than the universe?
The multiverse is bigger than the multiverse. A multiverse is defined as “an infinite realm of being or potential being of which the universe is regarded as a part or instance.”
Can we create a black hole?
To make a black hole, one must concentrate mass or energy sufficiently that the escape velocity from the region in which it is concentrated exceeds the speed of light.
What is secret of universe?
The Secret of the Universe (1991) is a collection of seventeen scientific essays by American writer and scientist Isaac Asimov. It is the twenty-second and final of a series of books collecting essays from The Magazine of Fantasy & Science Fiction (F&SF). Asimov died in 1992.
What is the smallest thing in the human body?
A cell is the smallest independently functioning unit of a living organism.
Why the universe is 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.
Who created the universe?
The earliest cosmological models of the universe were developed by ancient Greek and Indian philosophers and were geocentric, placing Earth at the center. Over the centuries, more precise astronomical observations led Nicolaus Copernicus to develop the heliocentric model with the Sun at the center of the Solar System.
What is bigger than a galaxy?
From largest to smallest they are: Universe, galaxy, solar system, star, planet, moon and asteroid.
What is the biggest black hole in the universe?
Cygnus X-1 is the heaviest stellar black hole observed without using gravitational waves. The famed Cygnus X-1 black hole (illustrated, slurping mass off its companion star) is nearly 1.5 times as massive as astronomers thought, new observations suggest.
What are the 4 main components of the universe?
The universe encompasses all of space, time, matter, and energy. The universe contains everything that exists, from particles of matter smaller than an atom to the largest stars.
What is the smallest thing in the universe?
Protons and neutrons can be further broken down: they’re both made up of things called “quarks.” As far as we can tell, quarks can’t be broken down into smaller components, making them the smallest things we know of.
Is the universe dark?
It turns out that roughly 68% of the universe is dark energy. Dark matter makes up about 27%. The rest – everything on Earth, everything ever observed with all of our instruments, all normal matter – adds up to less than 5% of the universe.
What is beyond the universe?
Astronomers think space outside of the observable universe might be an infinite expanse of what we see in the cosmos around us, distributed pretty much the same as it is in the observable universe. After all, it doesn’t make sense that one section of the universe would be different than what we see around us.
