What is there beyond the 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.
The current width of the observable universe is about 90 billion light-years. And presumably, beyond that boundary, there's a bunch of other random stars and galaxies.
The universe is everything. 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.
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.
The Big Freeze. Astronomers once thought the universe could collapse in a Big Crunch. Now most agree it will end with a Big Freeze. If the expanding universe could not combat the collective inward pull of gravity, it would die in a Big Crunch, like the Big Bang played in reverse.
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.
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.
Outer space is not completely empty—it is a near perfect vacuum containing a low density of particles, predominantly a plasma of hydrogen and helium, as well as electromagnetic radiation, magnetic fields, neutrinos, dust, and cosmic rays.
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.
“Why is there something instead of nothing?” has been sometimes labeled as the “biggest question of all.”
How did life start?
Many scientists believe that RNA, or something similar to RNA, was the first molecule on Earth to self-replicate and begin the process of evolution that led to more advanced forms of life, including human beings.

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.
No one created God. God got created as the universe grew and changes. God is the cumulative energy of the universe. So, infact universe created God.
According to Einstein's General Relativity, which is our best current description of space and time, the only place where time – and also space – ends is in a so-called singularity. This involves gravitational forces becoming so intense that space and time lose all meaning.
The result is unknown; a simple estimation would have all the matter and space-time in the universe collapse into a dimensionless singularity back into how the universe started with the Big Bang, but at these scales unknown quantum effects need to be considered (see Quantum gravity).
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.
The Big Bang was the moment 13.8 billion years ago when the universe began as a tiny, dense, fireball that exploded. Most astronomers use the Big Bang theory to explain how the universe began.
The comoving distance from Earth to the edge of the observable universe is about 14.26 gigaparsecs (46.5 billion light-years or 4.40×1026 m) in any direction. The observable universe is thus a sphere with a diameter of about 28.5 gigaparsecs (93 billion light-years or 8.8×1026 m).
What did God do before he created man?
Nothing. Since the world was created out of nothing (ex nihilo), nothingness prevailed. Therefore God was idling, just existing, perhaps contemplating creation.
The earliest life forms we know of were microscopic organisms (microbes) that left signals of their presence in rocks about 3.7 billion years old. The signals consisted of a type of carbon molecule that is produced by living things.
Something can be created from nothing
But such a perfect vacuum may not exist. One of the foundations of quantum theory is the Heisenberg uncertainty principle. It begins to be of profound importance to our understanding of nature at the atomic scale and below.
A succession of astronauts have described the smell as '… a rather pleasant metallic sensation ... [like] ... sweet-smelling welding fumes', 'burning metal', 'a distinct odour of ozone, an acrid smell', 'walnuts and brake pads', 'gunpowder' and even 'burnt almond cookie'.
Although there is nothing in physics that says time must flow in a certain direction, scientists generally agree that time is a very real property of the Universe.
Space is a vacuum.
With no molecules in the vacuum of space there is no medium for the sound waves to travel through. So there is no sound.
What is 11th dimension? The 11th dimension is a characteristic of space-time that has been proposed as a possible answer to questions that arise in superstring theory. The theory of superstrings involves the existence of nine dimensions of space and one dimension of time for a total of 10 dimensions.
The world as we know it has three dimensions of space—length, width and depth—and one dimension of time. But there's the mind-bending possibility that many more dimensions exist out there. According to string theory, one of the leading physics model of the last half century, the universe operates with 10 dimensions.
So, what is truth? Philosophers have struggled with this question since the dawn of time, perhaps because it's the hardest question ever asked. The field of epistemology is the subdiscipline of philosophy that grapples it, along with the nature of knowledge itself.

42 and the asterisk symbol
Forty-two is the ASCII code for the symbol * also known as the asterisk. This symbol is often thought to translate to anything or everything. In this instance, 42 = everything, the meaning of life.
The number 42 is, in The Hitchhiker's Guide to the Galaxy by Douglas Adams, the "Answer to the Ultimate Question of Life, the Universe, and Everything," calculated by an enormous supercomputer named Deep Thought over a period of 7.5 million years. Unfortunately, no one knows what the question is.
The number 42 is especially significant to fans of science fiction novelist Douglas Adams' “The Hitchhiker's Guide to the Galaxy,” because that number is the answer given by a supercomputer to “the Ultimate Question of Life, the Universe, and Everything.” Booker also wanted to know the answer to 42.
Overview. Homo sapiens, the first modern humans, evolved from their early hominid predecessors between 200,000 and 300,000 years ago. They developed a capacity for language about 50,000 years ago.
Humans are unusual animals by any stretch of the imagination. Our special anatomy and abilities, such as big brains and opposable thumbs, have enabled us to change our world dramatically and even launch off the planet.
Born from a lotus emerging from the navel of Vishnu, Brahma creates all the forms in the universe, but not the primordial universe itself.
The universe is finite but has no end or boundary, because that would mean there was somewhere beyond the end... And wherever you are, you are in the centre of an observable universe defined by the Hubble radius. If you imagine the universe as the surface of a balloon you can see that it has a specific size but no end.

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.
Will the Big Rip happen?
If the total amount of dark energy is increasing, the acceleration will also increase, eventually to the point where the very fabric of space-time tears itself apart and the cosmos pops out of existence. One prediction puts this hypothetical “big rip” scenario 22 billion years in the future.
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.
If the Universe holds enough matter, including dark matter, the combined gravitational attraction of everything will gradually halt this expansion and precipitate the ultimate collapse. Over time, galaxies, then individual stars, will smash into each other more frequently, killing off any life on nearby planets.
Space emits many wavelengths of light - including a lot of blue and red light that our human eyes can see - but also ultraviolet light, gamma rays, and X-rays, which remain invisible to us.
Space is very, very cold. The baseline temperature of outer space is 2.7 kelvins (opens in new tab) — minus 454.81 degrees Fahrenheit, or minus 270.45 degrees Celsius — meaning it is barely above absolute zero, the point at which molecular motion stops.
The Holographic Principle is one of several clues suggesting that the concept of “space” is an elaborate illusion—or, to be more precise, that it emerges from a deeper spaceless reality, much as living organisms emerge from inanimate matter.
The Beyond is an unobservable space outside the Multiverse. It is the remnants of the Second Cosmos and is inhabited by the Beyonders.
If such an edge existed, matter would no longer be evenly distributed, and near that edge, the universe would no longer look the same in all directions. Looking towards the edge, one would see fewer galaxies and stars. This would contradict our observations so far.
The Outside is a space of nothingness that is outside the Omniverse, and its diameter is equivalent to 100,000 Omniverses.
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.
How long until the universe ends?
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.
There is no evidence that the universe has an edge. The part of the universe we can observe from Earth is filled more or less uniformly with galaxies extending in every direction as far as we can see - more than 10 billion light-years, or about 6 billion trillion miles.
