Could the universe have always existed?

They found that it's possible that the universe had no beginning — that it has always existed into the infinite past and only recently evolved into what we call the Big Bang.

Has the universe always existed?

The widely accepted age of the universe, as estimated by general relativity, is 13.8 billion years. In the beginning, everything in existence is thought to have occupied a single infinitely dense point, or singularity. Only after this point began to expand in a "Big Bang" did the universe officially begin.

Can the universe be infinitely old?

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).

What is the theory that the universe has always existed?

The Big Bang theory says that the universe came into being from a single, unimaginably hot and dense point (aka, a singularity) more than 13 billion years ago. It didn't occur in an already existing space. Rather, it initiated the expansion—and cooling—of space itself.

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.

How Can the Universe Not Have a Beginning? | Roger Penrose

How did the universe come from nothing?

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.

Who created the 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.

How many universes are believed to exist?

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

Did Einstein believe the universe was infinite?

In contrast to this model, Albert Einstein proposed a temporally infinite but spatially finite model as his preferred cosmology during 1917, in his paper Cosmological Considerations in the General Theory of Relativity.

Would the universe exist without matter?

No. Experiments continue to show that there is no 'space' that stands apart from space-time itself... no arena in which matter, energy and gravity operate which is not affected by matter, energy and gravity.

What lies 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.

Can anything be older than the universe?

Far from being 13.8 billion years old, as estimated by the European Planck space telescope's detailed measurements of cosmic radiation in 2013, the universe may be as young as 11.4 billion years. If that is, indeed, the case, then Methuselah is one again older than the universe.

Does time ever end?

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.

How can something 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.

Was there universe 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.

Does the universe have a purpose?

The universe is highly unlikely to have a purpose, but humans have evolved to be highly purpose-driven. Our human sense of purpose is neither derived from nor dependent on the universe having a purpose.

What was the biggest blunder of Einstein?

When he called the cosmological constant his "greatest blunder" it really was a blunder; if he had instead listened to what the equations told him, he could have predicted the expanding Universe! Instead of adding in a cosmological constant, modern dark energy is treated as just another...

How will the universe end?

Eventually, the entire contents of the universe will be crushed together into an impossibly tiny space – a singularity, like a reverse Big Bang. Different scientists give different estimates of when this contraction phase might begin. It could be billions of years away yet.

Is there anything stationary in the universe?

No. Nothing is actually stationary and everything is in motion. You can appear stationary but that is an optical illusion.

Could a multiverse 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.

What is bigger than the universe?

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.

What is our universe called?

Universe is a name given to all the matter around us. Our universe is also called the cosmos. It is originally a greek word.

Who created the God?

We ask, "If all things have a creator, then who created God?" Actually, only created things have a creator, so it's improper to lump God with his creation. God has revealed himself to us in the Bible as having always existed. Atheists counter that there is no reason to assume the universe was created.

Was God created by the universe?

In the Bible it says that 'God created the heavens and the earth' which shows that god created everything. Furthermore, it also says in the Bible that 'the earth was formless and empty'.

Who is the God of universe?

Vishnu, Lord of the universe, is a Hindu God known to have reincarnated into more than one form called Avatars. In other words, he is recognizable through the faces of other gods who receive praise within the Hindu beliefs. Here we have sculptures of Vishnu and a few of his forms ranging 8th-19th century.
