It includes living things, planets, stars, galaxies, dust clouds, light, and even time. Before the birth of the Universe, time, space and matter did not exist. The Universe contains billions of galaxies, each containing millions or billions of stars. The space between the stars and galaxies is largely empty. Correspondingly, what is the universe composed of?
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.
Also, what is beyond the space? 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.
Similarly one may ask, what is space in simple words?
Space in simple understanding is an area or volume. Space or spacing may also refer to: Outer space, the area beyond the limit of the atmosphere of Earth. Space (physics), one of the fundamental concepts like time and mass.
Who is the creator of universe?
God

What is on the other side of a Blackhole?
The event horizon is a proposed boundary around a black hole. On the other side of it, the gravitational pull of the black hole is so strong that, in order to escape it, an object would have to be moving faster than the speed of light, a feat that almost all physicists agree is impossible.

What was the start of the universe?
about 13.8 billion years ago
Are we made of stars?
Stars that go supernova are responsible for creating many of the elements of the periodic table, including those that make up the human body. 'It is totally 100% true: nearly all the elements in the human body were made in a star and many have come through several supernovas. ' Are there other universes?
Together, these universes comprise everything that exists: the entirety of space, time, matter, energy, information, and the physical laws and constants that describe them. The different universes within the multiverse are called "parallel universes", "other universes", "alternate universes", or "many worlds". What is there the most of in the universe?
Composition. The universe is composed almost completely of dark energy, dark matter, and ordinary matter. Today, ordinary matter, which includes atoms, stars, galaxies, and life, accounts for only 4.9% of the contents of the Universe. What does space smell like?
As it turns out, space actually does have a distinct odor. Astronauts returning from space claim that their suits smell, in a word, burnt. The lingering scent of space is “acrid” and “metallic,” reminding the astronauts of charred meat or welding fumes. Does space ever end?
Interplanetary space extends to the heliopause, whereupon the solar wind gives way to the winds of the interstellar medium. Interstellar space then continues to the edges of the galaxy, where it fades into the intergalactic void. Why is space silent?
In space, no one can hear you scream. This is because there is no air in space – it is a vacuum. Sound waves cannot travel through a vacuum. 'Outer space' begins about 100 km above the Earth, where the shell of air around our planet disappears. How do you define space?
Space is the boundless three-dimensional extent in which objects and events have relative position and direction. Physical space is often conceived in three linear dimensions, although modern physicists usually consider it, with time, to be part of a boundless four-dimensional continuum known as spacetime. What is all of space called?
Most of the universe is empty space, called a vacuum, but it is an imperfect vacuum. There are clouds of interstellar dust and the tiny particles that make up the solar wind. Is there air on the moon?
The moon has no atmosphere, so it has no weather at all! Mars has only a very thin atmosphere but it does have weather. Why is space black?
Around Earth and the inner solar system, for example, space is filled with dust particles that get lit up by the sun, creating a diffuse glow over the entire sky. But that dust isn't a problem out where New Horizons is. Plus, out there, the sunlight is much weaker. How many planets are there in space?
eight planets
How many galaxies are there?
100 billion galaxies
Where does space end?
No, they don't believe there's an end to space. However, we can only see a certain volume of all that's out there. Since the universe is 13.8 billion years old, light from a galaxy more than 13.8 billion light-years away hasn't had time to reach us yet, so we have no way of knowing such a galaxy exists. What happens when you reach the end of space?
The expansion starts off fast, and there isn't enough matter and energy to overcome that initial expansion. The expansion rate drops but never reaches zero; the Universe expands forever and ends in a Big Freeze. Is space infinite in all directions?
Space spreads out infinitely in all directions. Furthermore, galaxies fill all of the space through-out the entire infinite universe. The flatness of the universe means that the geometry of spacetime is not curved or warped on the cosmic scale. Is the universe infinite?
The universe is unquestionably huge. The observable universe is still huge, but it has limits. That's because we know the universe isn't infinitely old — we know the Big Bang occurred some 13.8 billion years ago. That means that light has had “only” 13.8 billion years to travel. What is beyond the edge of the universe?
Technically, this is the farthest point in space and also the farthest in time that we can observe. That essentially forms the edge of the “Observable Universe”. What lies even beyond that is what is known as the “Opaque Universe”. This marks the limit of what we can observe but not what we can imagine. How fast is the Milky Way moving?
1.3 million miles per hour
How is space infinite?
If the universe is infinite, it has always been infinite. At the Big Bang, it was infinitely dense. Since then it has just been getting less dense as space has expanded. Imagine a large flat rubber sheet with sand placed as closely together as possible on the sheet. Does the universe have a center?
Space itself is curved, so as the universe expands from the Big Bang, it is somewhat like the two-dimensional space on a balloon. But just like the surface of that balloon, there is no center in the universe. How long will the universe last?
Assuming that dark energy continues to make the universe expand at an accelerating rate, in about 150 billion years all galaxies outside the Local Supercluster will pass behind the cosmological horizon.
