What is beyond the universe?
So, in some ways, infinity makes sense.
But “infinity” means that, beyond the observable universe, you won’t just find more planets and stars and other forms of material…you will eventually find every possible thing..
What is bigger than a supercluster?
Celestial bodies bigger than the supercluster: A light year is the distance traveled by light in one year and is equivalent to 9.46 trillion kilometers.
Can an atom die?
Since an atom has a finite number of protons and neutrons, it will generally emit particles until it gets to a point where its half-life is so long, it is effectively stable. … It undergoes something known as “alpha decay,” and it’s half-life is over a billion times longer than the current estimated age of the universe.
What is the biggest thing in the universe?
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 smallest thing in the universe?
As far as we can tell, quarks can’t be broken down into smaller components, making them the smallest things we know of. In fact, they’re so small that scientists aren’t sure they even have a size: they could be immeasurably small!
What is the most powerful thing on earth?
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’s more, these GRBs could be killing our chances of ever discovering life on other planets.
What’s inside a quark?
A quark is a tiny particle which makes up protons and neutrons. Atoms are made of protons, neutrons and electrons. It was once thought that all three of those were fundamental particles, which cannot be broken up into anything smaller. … Neutrons and protons are made up of quarks, which are held together by gluons.
How long would it take to get to Andromeda?
Andromeda is 2.54 Million ly away. That means when Alcubierre drive will be reality it will take 2.5 Million years to reach there. with current technology it takes around 20,000 years to travel 1 ly.
What universe do we live in?
We live on a planet called Earth that is part of our solar system. But where is our solar system? It’s a small part of the Milky Way Galaxy. A galaxy is a huge collection of gas, dust, and billions of stars and their solar systems.
What is bigger than the Andromeda Galaxy?
Until relatively recently, it was thought that our neighboring galaxy, Andromeda, was far larger than the Milky Way. But the Milky Way is, in fact, considerably larger than Andromeda.
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.
Which is the brightest galaxy?
the Andromeda galaxyExcluding the Large and Small Magellanic Clouds, which can’t be seen from northerly latitudes, the Andromeda galaxy – also known as M31 – is the brightest galaxy you can see. At 2.5 million light-years, it’s also the most distant thing visible to your unaided eye.
What is the biggest known star?
The largest known star in the universe is UY Scuti, a hypergiant with a radius around 1,700 times larger than the sun. And it’s not alone in dwarfing Earth’s dominant star.
What is the smallest galaxy in the universe?
Scientists at the University of California at Irvine have discovered a galaxy so small that it barely even qualifies as a galaxy. Deemed “Segue 2,” the dwarf galaxy only contains about 1,000 stars and is the least massive galaxy in the known universe, reports Phys.org.
