What is our universe called?
Answer and Explanation: There is no current name for our Universe, other than simply "the Universe", although we have names for our own home in the cosmos. Earth is part of the solar system of planets revolving around our Sun.
Our Sun is one of at least 100 billion stars in the Milky Way, a spiral galaxy about 100,000 light-years across.
"The term was in common use in Western astronomy 2,500 years ago," Stanley said, referring to stargazers in European countries. "So there's no way of knowing who first coined it and how it first came to be. It's one of those terms that's so old that its origin is generally forgotten by now."
The Milky Way Galaxy is just one of hundreds of billions of galaxies that populate our universe. Our galaxy's name - the Milky Way - is a translation from the Latin "Via Lactea" which is derived from the Greek word "Kiklios Galaxios" which means milky circle.
No, the universe contains all solar systems, and galaxies. Our Sun is just one star among the hundreds of billions of stars in our Milky Way Galaxy, and the universe is made up of all the galaxies – billions of them.
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).
From largest to smallest they are: Universe, galaxy, solar system, star, planet, moon and asteroid.
The Universe is the biggest and contains billions of galaxies. A galaxy is a huge collection of gas, dust, and billions of stars and their solar systems, all held together by gravity. Our galaxy is called the Milky Way galaxy.
To support life as we know it, planets must have liquid water and orbit in the right place in their solar systems, not too close and not too far from their star. Similarly, life will not emerge or survive for long near the centers of galaxies.

Who owns Milky Way?
Milky Way is a brand of chocolate-covered confectionery bar manufactured and marketed by Mars, Incorporated.
Currently, in 2020, it was estimated that there are around 2 trillion galaxies in the observable Universe. Each galaxy is unique, ranging in size from 10,000 light-years to hundreds of light-years. Galaxies have been classified under five categories: spiral, barred spiral, lenticular, elliptical, and irregular.
Our home galaxy, the Milky Way, contains at least 100 billion stars, and the observable universe contains at least 100 billion galaxies. If galaxies were all the same size, that would give us 10 thousand billion billion (or 10 sextillion) stars in the observable universe.
Our Earth orbits the Sun in our Solar System. Our Sun is one star among the billions in the Milky Way Galaxy. Our Milky Way Galaxy is one among the billions of galaxies in our Universe.
How dark does space get? If you get away from city lights and look up, the sky between the stars appears very dark indeed. Above the Earth's atmosphere, outer space dims even further, fading to an inky pitch-black.
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.
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.
Mainly because the Multiverse has a lower layer of darkness called the Dark Multiverse.

Is space infinite or finite?
There's a limit to how much of the universe we can see. The observable universe is finite in that it hasn't existed forever. It extends 46 billion light years in every direction from us. (While our universe is 13.8 billion years old, the observable universe reaches further since the universe is expanding).
So the furthest out we can see is about 46.5 billion light years away, which is crazy, but it also means you can look back into the past and try to figure out how the universe formed, which again, is what cosmologists do.
Why is the Universe so Big? The Universe is so big because it is constantly expanding, and it does so at a speed that even exceeds the speed of light. Space itself is actually growing, and this is going on for around 14 billion years or so.
While estimates among different experts vary, an acceptable range is between 100 billion and 200 billion galaxies, said Mario Livio, an astrophysicist at the Space Telescope Science Institute in Baltimore, Maryland.
All galaxies contain at least 100 billion suns or stars. That's why they are visible through a telescope.
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.
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.
Besides Earth, Mars would be the easiest planet to live on. Mars has liquid water, a habitable temperature and a bit of an atmosphere that can help protect humans from cosmic and solar radiation. The gravity of Mars is 38% that of the Earth.
The technology required to travel between galaxies is far beyond humanity's present capabilities, and currently only the subject of speculation, hypothesis, and science fiction. However, theoretically speaking, there is nothing to conclusively indicate that intergalactic travel is impossible.
Today, the mid regions, forming a ring from 6,500 light-years from the galaxy's center to around 26,000 light-years from the center, are the safest areas for life. Closer to the center, supernovas and other events are still common, and in the outskirts, there are fewer terrestrial planets and more gamma-ray bursts.
What existed before the galaxy?
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 Many Planets are in our Galaxy? NASA estimates that there are at least 100 billion planets in our Milky Way alone. Others estimated that the Milky Way galaxy might have anywhere between 100 to 200 billion planets. Currently, over 4,000 exoplanets have been discovered, and every day, more and more follow.

Answer: Yes, you can see a few other galaxies without using a telescope! Our nearest neighbors, the Large and Small Magellanic Clouds, are easy to see from the southern hemisphere. However, one of the most beautiful galaxies we can see with the naked eye is visible in the night sky all this month (November).
While the spatial size of the entire universe is unknown, it is possible to measure the size of the observable universe, which is approximately 93 billion light-years in diameter at the present day.
There Is Only One Sun
The word “sun” is often used to describe many multitudes of stars in our galaxy and beyond, but doing so is a misnomer. The Sun is the name of our star, just as Sirius is the brightest star in Canis Major.
Born from a lotus emerging from the navel of Vishnu, Brahma creates all the forms in the universe, but not the primordial universe itself.
What is the closest universe to ours?
The closest known galaxy to us is the Canis Major Dwarf Galaxy, at 236,000,000,000,000,000 km (25,000 light years) from the Sun. The Sagittarius Dwarf Elliptical Galaxy is the next closest , at 662,000,000,000,000,000 km (70,000 light years) from the Sun.
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.
While a handful of countries and wealthy individuals are flexing their cosmic muscles, the fact is that space really belongs to everyone—or perhaps to no one, says Andrea Ballestero, associate professor of anthropology.
The smallest of galaxies contain a “mere” few hundred million stars while the largest galaxies contain up to one hundred trillion stars! Scientists have been able to segment galaxies into 4 main types: spiral, elliptical, peculiar, and irregular.
Astronomers have previously noticed that the Milky Way sits in a large, flat array of galaxies called the Local Sheet, which bounds the Local Void. The Local Void extends approximately 60 megaparsecs (200 Mly), beginning at the edge of the Local Group.
Finally, the most probable fate of the planet is absorption by the Sun in about 7.5 billion years, after the star has entered the red giant phase and expanded beyond the planet's current orbit.
The water on our Earth today is the same water that's been here for nearly 5 billion years. So far, we haven't managed to create any new water, and just a tiny fraction of our water has managed to escape out into space. The only thing that changes is the form that water takes as it travels through the water cycle.
Jupiter formed less than 3 million years after the birth of the solar system, making it the eldest planet.
Our universe is but one in an unimaginably massive ocean of universes called … the multiverse. If that concept isn't enough to get your head around, physics describes different kinds of multiverse. The easiest one to comprehend is called the cosmological multiverse.
Earth-616 is the Marvel Universe as we know it, and its legacy stretches back to 1939. While the rolling timeline keeps things modern, the 616 universe has continued uninterrupted since the launch of FANTASTIC FOUR #1 in 1961.
Do multiverses exist?
Even though certain features of the universe seem to require the existence of a multiverse, nothing has been directly observed that suggests it actually exists. So far, the evidence supporting the idea of a multiverse is purely theoretical, and in some cases, philosophical.

Earth-616 is generally referred to as “our” universe. It has become such a Marvel institution that it was borrowed for the title of its upcoming documentary series Marvel's 616, which begins streaming exclusively on Disney+ this week.
The Venom symbiote originated on the planet Klyntar, where it was looked down upon and considered a "loser" for being a runt and lacking the advanced shapeshifting abilities possessed by other symbiotes.
