The widely accepted theory for the origin and evolution of the universe is the Big Bang model, which states that the universe began as an incredibly hot, dense point roughly 13.7 billion years ago. Here’s a breakdown of the Big Bang to now in 10 easy steps.

How can we determine the origin of our universe?
The best-supported theory of our universe’s origin centers on an event known as the big bang. This theory was born of the observation that other galaxies are moving away from our own at great speed in all directions, as if they had all been propelled by an ancient explosive force.
How did the universe start if there was nothing?
Virtually all astronomers now believe that the universe sprang forth in what is known as the “Big Bang” explosion, from a state of extraordinary compression and phenomenally high temperature in which forces such as gravity and electromagnetism were unified in a single, all-encompassing force.
Is there a way of knowing how old the universe is?
We do not know the exact age of the universe, but we believe that it is around 13 billion years – give or take a few billion. Astronomers estimate the age of the universe in two ways: (a) by looking for the oldest stars; and (b) by measuring the rate of expansion of the universe and extrapolating back to the Big Bang.
What did Stephen Hawking discover?
Hawking is best known for his discovery that black holes emit radiation which can be detected by special instrumentation. His discovery has made the detailed study of black holes possible. Stephen Hawking was born in Oxford, England on January 8, 1942.
What is the most accepted theory about the origin of life?
RNA World has been the prevailing theory for the origin of life since the 1980s. The emergence of a self-replicating catalytic molecule accounts for signature capabilities of living systems, but it doesn’t explain how the protobiological molecule itself arose.
How many universes are there?
In a new study, Stanford physicists Andrei Linde and Vitaly Vanchurin have calculated the number of all possible universes, coming up with an answer of 10^10^16.
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 is the oldest thing in the universe?
Astronomers have confirmed the discovery of one the oldest and most distant objects ever known in the universe — a star-forming galaxy 12.8 billion light-years away that started forming within a billion years of the Big Bang that kickstarted everything.
How did life first begin?
After things cooled down, simple organic molecules began to form under the blanket of hydrogen. Those molecules, some scientists think, eventually linked up to form RNA, a molecular player long credited as essential for life’s dawn. In short, the stage for life’s emergence was set almost as soon as our planet was born.
What was the first life on Earth?
Prokaryotes
Prokaryotes were the earliest life forms, simple creatures that fed on carbon compounds that were accumulating in Earth’s early oceans. Slowly, other organisms evolved that used the Sun’s energy, along with compounds such as sulfides, to generate their own energy.

Which theory failed to explain the origin of life?
Bergson’s theory proposed a non-Darwinian mechanism to produce new genetic information that, in turn, allowed well documented mechanisms, including natural selection, to function. So, Darwin theory fails to explain origin and transmission of variations. Thus, the correct answer is option B.
Which theory is not related to origin of life?
The theory of evolution, both currently and as first conceived by Darwin and Wallace, neither provides, nor requires, an explanation for the origin of life. As Gould (1987) noted over two decades ago, “Evolution, in fact, is not the study of origins at all.…
Which theory is based on religion?
Durkheim’s theory of religion exemplifies how functionalists examine sociological phenomena. According to Durkheim, people see religion as contributing to the health and continuation of society in general.
What is the belief in one God called?

What religions are against politics?
Adherents. In Christianity, some groups like Jehovah’s Witnesses, the Christadelphians, the Amish, the Hutterites, and the Exclusive Brethren reject politics on the grounds: Christ’s statements about His kingdom not belonging to this world means that earthly politics can/should/must be rejected.
Is mythology the same as religion?
