Beyond our observable Universe lies the unobservable Universe, which ought to look just like the part we can see. The way we know that is through observations of the cosmic microwave background and the large-scale structure of the Universe.
What is the outside of a universe?
To answer the question of what’s outside the universe, we first need to define exactly what we mean by “universe.” If you take it to mean literally all the things that could possibly exist in all of space and time, then there can’t be anything outside the universe.
How do we know what the universe looks like?
This knowledge comes from decades of innovative experiments and theories. Modern telescopes on the ground and in space detect the light from galaxies billions of light-years away, showing us what the universe looked like when it was young.
What is the biggest thing outside the universe?
Largest galactic collection: Shapley Supercluster
Containing more than 8,000 galaxies and with a mass of more than 10 million billion times that of the sun, the Shapley Supercluster is the largest structure in the local universe, according to the European Space Agency.
What is outside the visible universe? – Related Questions
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.
How long will the universe last?
22 billion years in the future is the earliest possible end of the Universe in the Big Rip scenario, assuming a model of dark energy with w = −1.5. False vacuum decay may occur in 20 to 30 billion years if the Higgs field is metastable.
What happens after the universe dies?
Trillions of years in the future, long after Earth is destroyed, the universe will drift apart until galaxy and star formation ceases. Slowly, stars will fizzle out, turning night skies black. All lingering matter will be gobbled up by black holes until there’s nothing left.
Can we travel back in time?
Time travel to the past is theoretically possible in certain general relativity spacetime geometries that permit traveling faster than the speed of light, such as cosmic strings, traversable wormholes, and Alcubierre drives.
When did time begin?
According to the standard big bang model of cosmology, time began together with the universe in a singularity approximately 14 billion years ago.
What is the largest void in the universe?
At nearly 330 million light-years in diameter (approximately 0.27% of the diameter of the observable Universe), or nearly 236,000 Mpc3 in volume, the Boötes void is one of the largest known voids in the Universe, and is referred to as a supervoid. Its discovery was reported by Robert Kirshner et al.
What’s the biggest object on earth?
The world’s biggest thing to ever live and survive on the planet is the giant Antarctic blue whale.
What was there before the universe?
In the beginning, there was an infinitely dense, tiny ball of matter. Then, it all went bang, giving rise to the atoms, molecules, stars and galaxies we see today. Or at least, that’s what we’ve been told by physicists for the past several decades.
How big is the biggest thing in the universe?
The biggest thing we have discovered so far in our Universe is the Hercules-Corona Borealis Great Wall. It is a supercluster which has a diameter of around 10 billion light-years.
What’s 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 fastest thing in the universe?
Light is fast. In fact, it is the fastest thing that exists, and a law of the universe is that nothing can move faster than light. Light travels at 186,000 miles per second (300,000 kilometers per second) and can go from the Earth to the Moon in just over a second.
What is the universe made of?
It includes all of space, and all the matter and energy that space contains. It even includes time itself and, of course, it includes you. Earth and the Moon are part of the universe, as are the other planets and their many dozens of moons. Along with asteroids and comets, the planets orbit the Sun.
What is beyond our 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.
What are 3 ways the universe could end?
