What was there before the universe?

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.

What was before the universe was created?

“Inflation tells us that the period of time before the Big Bang was extremely cold, almost at absolute zero, and it was empty of everything but empty space, and that empty space carried energy that stretched the universe out to this enormous size and into the initial state before the Big Bang.

What was before the universe called?

The initial singularity is a singularity predicted by some models of the Big Bang theory to have existed before the Big Bang and thought to have contained all the energy and spacetime of the Universe.

What came first before the universe?

This breakthrough idea later became known as the Big Bang! 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.

What was 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.

Brian Greene - What Was There Before The Big Bang?

How many dimensions exist?

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.

Is it possible to leave the universe?

Thanks to dark energy and the accelerated expansion of the Universe, it's physically impossible to even reach all the way to the edge of today's observable Universe; we can only get a third of the way there at maximum.

Will I exist again if time is infinite?

It is impossible to destroy and create matter. Thus, everything that has existed still exists, and everything that will exist already exists, just not in the state(s) it did or is going to. And even if time is infinite you would not be born again.

What created the universe?

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.

How did matter come from nothing?

In the quantum realm, something really can emerge from nothing. In theory, the Schwinger effect states that in the presence of strong enough electric fields, (charged) particles and their antiparticle counterparts will be ripped from the quantum vacuum, empty space itself, to become real.

When did time exist?

According to the standard big bang model of cosmology, time began together with the universe in a singularity approximately 14 billion years ago.

Is space infinite?

We could think of the universe as a sphere expanding indefinitely and infinitely. Or it might curve and bend in ways that could make it a closed system (like a donut), where if you were to travel in a straight line for long enough, eventually you'd end up back where you started: space would be finite.

How long will the universe exist?

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.

Did a universe existed before ours?

"There was actually another universe existing before the present one and the Big Bang merely marked the end of that universe. Evidence of that previous universe can still be observed these days," he said.

Who is the creator of universe?

Many religious persons, including many scientists, hold that God created the universe and the various processes driving physical and biological evolution and that these processes then resulted in the creation of galaxies, our solar system, and life on Earth.

Which God is the creator of the universe?

In other versions of creation, the creator deity is the one who is equivalent to the Brahman, the metaphysical reality in Hinduism. In Vaishnavism, Vishnu creates Brahma and orders him to order the rest of universe. In Shaivism, Shiva may be treated as the creator. In Shaktism, the Great Goddess creates the Trimurti.

Where am I in the universe?

Our planet is part of a discrete solar system in an arm of the spiral shaped Milky Way Galaxy. Our galaxy is only one of billions of other galaxies that exist within the universe. How many planets are in our solar system? There are eight planets in our solar system and three dwarf planets.

Could humans stop time?

In order for you to stop time, you would have to be traveling infinitely fast. Nothing can travel faster than light (let alone infinitely fast) without gaining infinite mass and energy, according to Einstein's theory of relativity.

Can anything past infinity?

Infinity is a concept, not a number or a fixed boundary, and thus it cannot be passed. Infinity is the idea or concept of something that has no end. Infinity is endless and therefore cannot be reached. The expressions “beyond infinity” or “to infinity and beyond" simply represent limitless possibilities.

Will time itself end?

Einstein's general theory of relativity predicts that time ends at moments called singularities, such as when matter reaches the center of a black hole or the universe collapses in a “big crunch.” Yet the theory also predicts that singularities are physically impossible.

What happens after the universe dies?

As existing stars run out of fuel and cease to shine, the universe will slowly and inexorably grow darker. Eventually black holes will dominate the universe, which themselves will disappear over time as they emit Hawking radiation.

How much of the universe have we seen?

We know only five per cent of the universe. The remaining 95 per cent is still a mystery – an unknown universe of new particles and forces awaits discovery.

How many other universes are there?

We currently have no evidence that multiverses exists, and everything we can see suggests there is just one universe — our own.
