Could the universe be created from nothing?

Many scientists assume that the universe came from nothing, which is an idea that can only be true in light of quantum theory. Ultimately, quantum fluctuations could allow a universe to spontaneously form from nothing.

What was the universe before nothing?

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.

Is it possible to recreate the universe?

Although that may not be possible, physicists can recreate the young universe in high energy particle collisions. Recent results indicate that the young universe may be stranger than anticipated.

How much of the universe is made up of nothing?

So all of the matter in the universe would fit into about 1 billion cubic light years, or a cube that's approximately 1,000 light years on each side. That means that only about 0.0000000000000000000042 percent of the universe contains any matter. The universe is a pretty empty place!

How does matter exist if it Cannot be created?

Matter can change form through physical and chemical changes, but through any of these changes matter is conserved. The same amount of matter exists before and after the change—none is created or destroyed. This concept is called the Law of Conservation of Mass.

If the Universe Formed from Nothing, Who Created the Nothing?

How did everything in the universe come to exist?

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.

Can space exist by itself 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.

How did life start from nothing?

One of the leading theories is that life emerged from chemical processes in Earth's early ocean. Simple chemical precursors, such as water, carbon, and hydrogen, mixed and mingled until they formed complex polymers like DNA, RNA, and protein—the building blocks of life.

How did we come from nothing?

Our Universe is made of matter (rather than antimatter), obeys the same laws of physics everywhere and at all times, and began — at least, as we know it — with a hot Big Bang some 13.8 billion years ago.

What is outside 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.

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.

Could the universe go on forever?

Scientists now consider it unlikely the universe has an end – a region where the galaxies stop or where there would be a barrier of some kind marking the end of space.

Was God created by the universe?

According to the Book of Genesis, God created the universe - and all the heavenly bodies, the sun, the moon, and the stars - in six days. But according to contemporary cosmologists the universe began with a great explosion known as the Big Bang, after which the stars and galaxies slowly formed over billions of years.

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 existed first in the universe?

In the first moments after the Big Bang, the universe was extremely hot and dense. As the universe cooled, conditions became just right to give rise to the building blocks of matter – the quarks and electrons of which we are all made.

What was before the ball of matter?

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.

Where did life come from?

Mineral-laden water emerging from a hydrothermal vent on the Niua underwater volcano in the Lau Basin, southwest Pacific Ocean. The microorganisms that live near such plumes have led some scientists to suggest them as the birthplaces of Earth's first life forms.

Have scientists created something out of nothing?

Creating Particle-Antiparticle Pairs from Nothing

The researchers used these fields to create particle-antiparticle pairs from nothing. This proved that it is possible to create matter out of nothing, a theory initially stated in 1951 by Julian Schwinger, one of the pioneers of quantum field theory.

Did we create matter from nothing?

But in reality, the physics of our universe isn't that cut and dry. In fact, scientists have spent decades trying to force matter from absolutely nothing. And now, they've managed to prove that a theory first shared 70 years ago was correct, and we really can create matter out of absolutely nothing.

Why life was created?

In this sense, life is a very natural thing, which emerged simply to satisfy basic physical laws. Our “purpose,” so to speak, is to redistribute energy on the Earth, which is in between a huge potential energy difference caused by the hot Sun and cold space.

Did life only start once?

The variety of life on Earth is widely considered to have evolved from a single common ancestor, but it is possible that basic organisms emerged more than once, leading to multiple trees of life.

Have scientists created life from nonlife?

Five years ago, scientists created a single-celled synthetic organism that, with only 473 genes, was the simplest living cell ever known. However, this bacteria-like organism behaved strangely when growing and dividing, producing cells with wildly different shapes and sizes.

Is space ever truly empty?

Physicists tell us that there is no such thing as empty space. Imagine that you have removed every atom from a small box to try to make a perfect vacuum inside. That would be difficult but not impossible.

Is any space truly empty?

Space is not empty. A point in outer space is filled with gas, dust, a wind of charged particles from the stars, light from stars, cosmic rays, radiation left over from the Big Bang, gravity, electric and magnetic fields, and neutrinos from nuclear reactions.

Does dark matter exist?

In fact, researchers have been able to infer the existence of dark matter only from the gravitational effect it seems to have on visible matter. Dark matter seems to outweigh visible matter roughly six to one, making up about 27% of the universe.
