A look at various theories explaining the origin of the known universe

Nevertheless, even the most rapid traveler will not be able to interact with all of space. As the universe expanded, according to current scientific understanding, matter collected into clouds that began to condense and rotate, forming the forerunners of galaxies.

Some of these molecules also have been detected in meteorites from outer space and in interstellar space by astronomers using radio-telescopes. Then it continues to expand slowly for billions of years. Special creation or supernatural intervention is not subjectable to meaningful tests, which require predicting plausible results and then checking these results through observation and experimentation.

This lead to a multiverse where the space is broken and divided into huge bubbles, with each bubble having different properties.

The model is based on general relativity and on simplifying assumptions such as homogeneity and isotropy of space.

Together, these epochs encompassed less than 10 seconds of time following the Big Bang. These elementary particles associated stably into ever larger combinations, including stable protons and neutronswhich then formed more complex atomic nuclei through nuclear fusion.

But inastronomers announced the discovery of a group of galaxies and quasars that fills more than million million cubic light-years of space, and is presently the largest structure in the universe. The idea violates a fundamental law of physics: At first glance, it would seem so. But what cosmologists failed to explain is what triggered this explosion.

Creationist Views of the Origin of the Universe, Earth, and Life 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.

By traveling, an observer can come into contact with a greater region of spacetime than an observer who remains still. Observable universe and Observational cosmology The size of the Universe is somewhat difficult to define. The sequence of nucleotides in DNA and RNA therefore determines the sequence of amino acids in proteins; this is a central mechanism in all of biology.

Instead, it comes from laboratory experiments. Scientists are designing experiments and speculating about how early Earth could have provided a hospitable site for the segregation of Page 7 Share Cite Suggested Citation: With enough mass, the universe will eventually succumb to the overpowering force of gravity and collapse again into a single point—a theory often called the Big Crunch.

These conclusions make the origin of the universe as a whole intelligible, lend coherence to many different branches of science, and form the core conclusions of a remarkable body of knowledge about the origins and behavior of the physical world.

The age of the universe can be derived from the observed relationship between the velocities of and the distances separating the galaxies. The discovery of quasars has put the Steady State theory on unsteady ground.

In the Plasma Universe, galaxies come together slowly over a much greater time span than in the Big Bang theory, perhaps taking as long as billion years. Will we ever be able to identify the path of chemical evolution that succeeded in initiating life on Earth?

If the source is moving away from you, the waves drop in frequency: Take a look at star stuff and more in this video show.What are the various theories that aim to explain the origin of the universe? Update Cancel. What are the other theories aside from big bang and steady state theory explaining the origin of the universe?

What are the theories of punishment? Ask New Question. Still have a question? Ask your own! In this section, we're going to take a brief excursion through the various theories that science has put forth to explain the origin of the universe. By far the most popular theory in science today is the big bang theory, the idea that the universe came into existence at a certain point in time roughly 15 to 20 billion years ago.

According to physics, the universe sprang into existence from a singularity — a term physicists use to describe regions of space that defy the laws of physics.

They know very little about singularities, but it's known that such regions exist in the cores of black holes. Creationist Views of the Origin of the Universe, Earth, and Life 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.

The Origin of the Universe

The currently popular theory of the origin of the universe held various rates of speed. According to a basic assumption called the cosmological principle, the stars would show an identical expansion explaining an ultimate origin and a final destiny for the universe.

However, recent data reveals that there is simply not enough. Theories explaining the origin of the universe. 1. In the Bible, there was time when the world did not exist. Only God existed.
