What theory states that the universe has always been the same since the beginning?
steady-state theory
steady-state theory, in cosmology, a view that the universe is always expanding but maintaining a constant average density, with matter being continuously created to form new stars and galaxies at the same rate that old ones become unobservable as a consequence of their increasing distance and velocity of recession.
What 3 Forces does quantum mechanics unify?
Quantum Mechanics describes in detail three fundamental forces; the strong (affecting particles inside the nucleus of an atom), the weak (responsible for radioactive decay), and the electromagnetic (binding electrons to atoms, and allowing atoms to work together to form everything we know).
What ultimately determines the fate of the universe?
Everything in the universe exerts a gravitational pull on everything else, and this slows down the universal expansion. The ultimate fate of the universe depends on the amount of mass contained within it, that is, the mean density of the universe.
Which of the following states that the universe originated from a singularity that expanded continuously?
Big Bang Theory states that the universe started as a singularity that exploded. This explosion resulted to the formation of all the matter in universe.
What is cosmic inflation theory?
In physical cosmology, cosmic inflation, cosmological inflation, or just inflation, is a theory of exponential expansion of space in the early universe. The acceleration of this expansion due to dark energy began after the universe was already over 7.7 billion years old (5.4 billion years ago).
Who created the God?
We ask, “If all things have a creator, then who created God?” Actually, only created things have a creator, so it’s improper to lump God with his creation. God has revealed himself to us in the Bible as having always existed. Atheists counter that there is no reason to assume the universe was created.
What are the four fundamental forces?
There are four fundamental forces at work in the universe: the strong force, the weak force, the electromagnetic force, and the gravitational force. They work over different ranges and have different strengths. Gravity is the weakest but it has an infinite range.
What are the four forces?
fundamental force, also called fundamental interaction, in physics, any of the four basic forces—gravitational, electromagnetic, strong, and weak—that govern how objects or particles interact and how certain particles decay. All the known forces of nature can be traced to these fundamental forces.
What are the 3 fates of the universe?

Which theory suggests that the universe began from a singularity and its inflation?
The Big Bang Theory
The Big Bang Theory is the leading explanation for how the universe began.
What is a spacetime singularity and why is it important?
A spacetime singularity is a breakdown in spacetime, either in its geometry or in some other basic physical structure. It is a topic of ongoing physical and philosophical research to clarify both the nature and significance of such pathologies.
What are the three fundamental forces of the universe?
Near the end of this era, grand unified theories predict that the universe cooled to the point that the nuclear strong force began to freeze out, leaving three fundamental forces: gravity, the strong force, and the still combined electroweak force.
What is the strongest force in the universe?
The strong nuclear force The strong nuclear force, also called the strong nuclear interaction, is the strongest of the four fundamental forces of nature. It’s 6 thousand trillion trillion trillion (that’s 39 zeroes after 6!) times stronger than the force of gravity, according to the HyperPhysics website.
Did the Big Bang start with a singularity?
Traditional Big Bang theory posits that our universe began with a singularity — a point of infinite density and temperature whose nature is difficult for our minds to grasp. However, this may not accurately reflect reality, researchers say, because the singularity idea is based on Einstein’s theory of general relativity.
