What theory explains that the universe was the same and its original form from the beginning?
The Big Bang Theory is our best guess about how the universe began. A 2013 map of the background radiation left over from the Big Bang, taken by the ESA’s Planck spacecraft, captured the oldest light in the universe. This information helps astronomers determine the age of the universe.
Which of the following is the most accepted theory about the formation of the universe that explains why it continues to expand Brainly?
The Big Bang theory is the most widely accepted cosmological explanation of how the universe formed.
What are the theories in the formation of the universe?
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.

What is a physics theory?
In physics the term theory or physical theory traditionally refers, somewhat vaguely, to a given set of notions and rules, usually formulated in the language of mathematics, that describe how some physical system or class of physical systems behaves.
How many physics theories are there?
Theoretical physics attempts to understand the natural world by making a model of reality, used for rationalizing, explaining, and predicting physical phenomena in what are called “physical theories.” There are three types of theories in physics: mainstream theories, proposed theories and fringe theories.
What is the steady state theory of the universe?
This theory didn’t depend on a specific event like the Big Bang. Under the Steady State theory, stars and galaxies may change, but on the whole the universe has always looked the way it does now, and it always will. The Big Bang predicts that as galaxies recede from one another, space becomes progressively emptier.
How do we know the origin of the universe?
Advances ranging from more-sensitive telescopes to experiments in physics should add more fuel to the cosmological debate during the coming decades. But the Big Bang is not the only proposed theory concerning our universe’s origin. In the 1940s a competing hypothesis arose, called the Steady State theory.
Why is the Big Bang theory not widely accepted?
The Big Bang model is not uniformly accepted, however. One problem with the theory is that it predicts a smooth universe. That is, the distribution of matter, on a large scale, should be roughly the same wherever you look. No place in the universe should be unduly lumpy.
What exactly is physics?
Published June 1, 2018This article is more than 2 years old. Physics is the study of, well, everything. Time, space, matter, energy—whether it’s the gravity that keeps your coffee in your cup or the thermodynamics that heats up your lunch, physics isn’t the stuff of a faraway land filled with mathematicians and dusty blackboard erasers.
