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

Advances ranging from more-sensitive telescopes to experiments in physics should add more fuel to the cosmological debate during the coming decades. The oldest known rocks on Earth occur in northwestern Canada 3. Instead, it comes from laboratory experiments.

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.

The velocities of distant galaxies can be measured very accurately, but the measurement of distances is more uncertain. The plasma universe theory basically suggests that everything in the universe, i. But it is the job of science to provide plausible natural explanations for natural phenomena.

Within galaxies, including our own Milky Way galaxy, changes in pressure caused gas and dust to form distinct clouds.

The Origin of the Universe

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.

Each of these molecules is in turn composed of four kinds of subunits known as nucleotides. Observable universe and Observational cosmology The size of the Universe is somewhat difficult to define.

The Origin, History, Evolution & Future of the Universe

Some scientists favor the hypothesis that there was an early "RNA world," and they are testing models that lead from RNA to the synthesis of simple DNA and protein molecules.

This supposition came from an unusual finding about our neighboring galaxies. All of the different elements in the universe today developed from what spewed out of this original explosion. 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.

The implication of these findings is that the universe is expanding. The sequences of nucleotides in particular lengths of DNA or RNA, known as genes, direct the construction of molecules known as proteins, which in turn catalyze biochemical reactions, provide structural components for organisms, and perform many of the other functions on which life depends.

The observable universe depends on the location of the observer. While still a minority view, the Plasma Universe is gaining favor with younger, more laboratory-minded astronomers who value hard empirical evidence over mathematical proofs.

The answer depends on the amount of mass that the universe contains. Other astronomers have since corroborated this finding using a variety of methods, and have all but confirmed the existence of this mysterious "dark energy.

British astrophysicist Fred Hoyle and others argued that the universe was not only uniform in space—an idea called the cosmological principle—but also unchanging in time, a concept called the perfect cosmological principle.

Hubble explained this shift by concluding that the galaxies were in motion, whizzing away from Earth.

Proponents of the Big Bang maintain that, between 13 billion and 15 billion years ago, all the matter and energy in the known cosmos was crammed into a tiny, compact point. Estimates of the ages of the stars in globular clusters fall within the range of 11 billion to 16 billion years.

After around - million years,[ citation needed ] the first stars formed, known as Population III stars. Together, these epochs encompassed less than 10 seconds of time following the Big Bang. In spite of its problems, the Big Bang is still considered by most astronomers to be the best theory we have.

At current, all the understandings of the physics, all known theories are unable to explain what happened that particular moment. According to this theory, the phase where the universe inflates will go on forever, throughout the larger parts of the universe.

But they argue that the various types of organisms, and especially humans, could only have come about with supernatural intervention, because they show "intelligent design.

At first glance, it would seem so.

But the processes by which planets, stars, galaxies, and the universe form and change over time are also types of "evolution.

In fact, the Cosmic Microwave Background Explorer COBE satellite launched in confirmed that the background radiation field has exactly the spectrum predicted by a Big Bang origin for the universe. Plasma, an ionized gas that conducts electricity, is sometimes called the fourth state of matter. As the universe continued to cool down from its inconceivably hot state, various types of subatomic particles were able to form, in short periods of time known as the quarkhadronand lepton epochs.

At around 47, years, the energy density of matter became larger than that of photons and neutrinosand began to dominate the large scale behavior of the universe. Different plasma theories state that the space we observe is filled with enormous filaments of electrons and ions, and these are distorted due to the strong electromagnetic forces, thus giving birth to huge physical matters like galaxies.

After all, no one was around when the universe began, so who can say what really happened? Soon the entire scientific community was debating on the possible origin of the universe. As with any scientific hypothesis, however, more observation and experimentation are needed to determine its credibility.

The raisins inside begin to spread apart from each other.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. Since the early part of the s, one explanation of the origin and fate of the universe, the Big Bang theory, has dominated the discussion.

Proponents of the Big Bang maintain that, between 13 billion and 15 billion years ago, all the matter and energy in the known cosmos was crammed into a tiny, compact point.

Because of its success in explaining a wide variety of experimental results However, this equilibrium is unstable: because the Universe is known to be inhomogeneous on smaller scales, R must change (cosmologies) and its origin (cosmogonies).

Theories of an impersonal Universe governed by physical laws were first proposed by the. 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.
