Horizon plunges down the biggest rabbit-hole in history in search of the smallest thing in the Universe. It is a journey where things don’t just become smaller but also a whole lot weirder.
How big is the universe visualized?
The universe is vast; it has been expanding for almost 13.8 billion years at a considerable fraction of the speed of light, so what we can see is a sphere roughly 28 billion light years across. This means that the observable universe is ~1026 m across.
How big is the universe article?
The observable Universe is 93 billion light-years in diameter. Some scientists believe its true size is even scarier than that. By using the Bayesian model averaging, scientists estimated that the Universe is at least 250 times larger than the observable Universe, or at least 7 trillion light-years in diameter.
How big is the universe BBC Horizon?
A milky way could fit inside 10 million, million, million times. Our entire galaxy is just a dot on the landscape. In the observable universe, there are 170 billion galaxies just like it.

How small is the universe documentary? – Related Questions
Why is space 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.
How is our universe?
Our universe began with an explosion of space itself – the Big Bang. Starting from extremely high density and temperature, space expanded, the universe cooled, and the simplest elements formed. Gravity gradually drew matter together to form the first stars and the first galaxies.
How will the universe end?
In the unimaginably far future, cold stellar remnants known as black dwarfs will begin to explode in a spectacular series of supernovae, providing the final fireworks of all time. That’s the conclusion of a new study, which posits that the universe will experience one last hurrah before everything goes dark forever.
Who created universe?
Many religious persons, including many scientists, hold that God created the universe and the various processes driving physical and biological evolution and that these processes then resulted in the creation of galaxies, our solar system, and life on Earth.
Who created the world?
According to Christian belief, God created the universe. There are two stories of how God created it which are found at the beginning of the book of Genesis in the Bible.
What are the 3 types of universe?
There are basically three possible shapes to the Universe; a flat Universe (Euclidean or zero curvature), a spherical or closed Universe (positive curvature) or a hyperbolic or open Universe (negative curvature).
What are we in the universe?
In the vast, expanding space known as the universe, humans reside on a small, rocky planet called Earth. Our planet is part of a discrete solar system in an arm of the spiral shaped Milky Way Galaxy. Our galaxy is only one of billions of other galaxies that exist within the universe.
Is the universe infinite?
The observable universe is finite in that it hasn’t existed forever. It extends 46 billion light years in every direction from us.
What is bigger than a universe?
No, the universe contains all solar systems, and galaxies.
How many universes are there?
In a new study, Stanford physicists Andrei Linde and Vitaly Vanchurin have calculated the number of all possible universes, coming up with an answer of 10^10^16.
Does our universe have an end?
There is no evidence that the universe has an edge. The part of the universe we can observe from Earth is filled more or less uniformly with galaxies extending in every direction as far as we can see – more than 10 billion light-years, or about 6 billion trillion miles.
What is the biggest thing in existence?
The biggest single entity that scientists have identified in the universe is a supercluster of galaxies called the Hercules-Corona Borealis Great Wall. It’s so wide that light takes about 10 billion years to move across the entire structure. For perspective, the universe is only 13.8 billion years old.
What is the most powerful thing in the universe?
These explosions generate beams of high-energy radiation, called gamma-ray bursts (GRBs), which are considered by astronomers to be the most powerful thing in the universe.
What is the biggest void in the universe?
The Boötes void (/boʊˈoʊtiːz/)[1] (colloquially referred to as the Great Nothing) is an approximately spherical region of space found in the vicinity of the constellation Boötes, containing very few galaxies, hence its name. It is enormous, with a radius of 62 megaparsecs.
What is the darkest place in the universe?
The Darkest Part of the Universe–Boötes Void
Located around 700 million light-years from Earth, the Boötes void was first discovered by American Astronomer Robert Kirshner alongside with his University of Michigan colleagues back in 1981, during a survey of galaxy redshifts.
Is there a hole in the universe?
The Boötes void, often referred to as the Great Nothing or the Great Void, is an actual area of space with fewer galaxies than you’d expect. At 250 to 330 million light-years across, it is one of the largest voids that we know of.
What is beyond the universe?
The trite answer is that both space and time were created at the big bang about 14 billion years ago, so there is nothing beyond the universe. However, much of the universe exists beyond the observable universe, which is maybe about 90 billion light years across.
