Common theories about the origin of the universe
Big Bang
Description
According to this theory the universe expanded from a extremely small, hot and dense state.
Since then it has expanded and become less dense and cooler.
The Big Bang is the best model used by astronomers to explain the creation of matter, space and time 13.7 billion years ago.
Beggining of the universe
The Universe expanded from an extremely small, extremely hot, and extremely dense state
Evidence
Hubble’s discovery in the 1920s of a relationship between a galaxy’s distance from Earth and its speed
The discovery in the 1960s of cosmic microwave background radiation.
Expantion and future of the universe
Big Rip proposes that the expansion of the universe will continue eternally instigated by dark energy,
Leading to an increasingly colder and degraded cosmos in which each galaxy will move further and further away, becoming isolated from all the others.
My opinion
From my pinto of view this theory is the most credible that I have heard and the most important thing is that it has evidence of it.
Cosmic inflation
Description
According to the theory of inflation, the early Universe expanded exponentially fast for a fraction of a second after the Big Bang.
My opinion
These was after the big bang, so it made me more sense that the universe still increasing and we will die very cold.
Beggining of the universe
This problem can be solved by the idea that the Universe expanded exponentially for a short time period after the Big Bang.
Expantion and future of the universe
Using classical physics, the evolution of the inflationary Universe is homogeneous - each spatial point evolves exactly the same way.
A simple model for the expansion of the Universe is to consider the inflation of the balloon.
A person at any point on the balloon might consider themselves to be at the centre of the expansion, as all neighbouring points are getting further away.
Ocilliating Universe
Description
A modification of the Big Bang theory, in which an expanding universe eventually reverses and collapses back to a Big Crunch before starting to expand again, forming one cycle of an endless series.
In such a model, each cycle has a finite duration but the universe itself can last for an infinite time.
My opinion
My opinion is that the theory is more complete by adding two types of theorys which are the most reasonables ones. Has evideces and all the information requested ( beggining, description, etc) is found.
Beggining of the universe
The Universe is believed to be expanding from a very hot, very dense, and very small entity.
Expantion and future of the universe
The most recent measurements of the CMBR or cosmic microwave background.
Radiation shows that the Universe will continue on expanding and will most likely end in what is known as a Big Freeze or Heat Death.
Evidence
The Oscillating Big Bang theory is supported by the observed expansion of the universe.
The detection of cosmic microwave radiation, and the predicted elemental abundance in the universe that aligns with the Big Bang nucleosynthesis.
Cosmic creation
Description
It brings together several theories to describe the beginning of the universe involving theories
Physics
Cosmology
Religious
Evidence
Cosmic Microwave Background (CMB) RadiationThe "Echo" of the Big Bang.
Abundance of Light Elements (Helium, Hydrogen, Lithium, Deuterium).
Gravitational Waves and Cosmic Inflation (Indirect Evidence)
Expantion and future of the universe
The most likely outcome is heat death (Big Freeze), but scenarios like the Big Rip, Big Crunch, or Big Bounce remain possibilities.
Beggining of the universe
The universe began about 13.8 billion years ago from a singular, extremely hot and dense state and has been expanding ever since.
My opinion
Well in my opinion these theory is not so true because it believe of the religion part. But besides that the others theorys that uses are more credible.
