What is beyond the known universe?
Right now, in a 13.8 billion year old Universe, our current visibility limit is 46 billion light-years.
Beyond our observable Universe lies the unobservable Universe, which ought to look just like the part we can see..
Who died on the moon?

What is the most massive thing in the universe?
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.
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 outside the expanding universe?
The universe is everything, so it isn’t expanding into anything. It’s just expanding. All of the galaxies in the universe are moving away from each other, and every region of space is being stretched, but there’s no center they’re expanding from and no outer edge to expand into anything else.
Is there anything further than the universe?
nothing – the universe is everything there is, so nothing can be bigger than it.
What’s bigger than the Galaxy?
Galaxies come in many sizes. The Milky Way is big, but some galaxies, like our Andromeda Galaxy neighbor, are much larger. The universe is all of the galaxies – billions of them! … Our Sun is one star among the billions in the Milky Way Galaxy.
Which is bigger cosmos or universe?
The term “cosmos” has two connotations. … The words “cosmos” and “universe” are used synonymously as they refer to the same concept which is the world or nature. “Universe” seems to have a narrower or smaller scope than “cosmos,” though, and “cosmos” signifies a larger and more complex system.
Why is space expanding?
The space between objects shrinks or grows as the various geodesics converge or diverge. Because this expansion is caused by relative changes in the distance-defining metric, this expansion (and the resultant movement apart of objects) is not restricted by the speed of light upper bound of special relativity.
Does space have an 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.
Is nothingness possible?
There is no such thing as nothingness, and zero does not exist.
How cold is space?
Hot things move quickly, cold things very slowly. If atoms come to a complete stop, they are at absolute zero. Space is just above that, at an average temperature of 2.7 Kelvin (about minus 455 degrees Fahrenheit).
Who created the universe?
In his 1988 book, A Brief History of Time, Hawking had seemed to accept the role of God in the creation of the universe. But in the new text, co-written with American physicist Leonard Mlodinow, he said new theories showed a creator is “not necessary”.
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.
