No, you have that totally wrong. Inflation is how matter and energy got into the universe. Can you show me where anyone says otherwise than you?
Here's the interview where Vilenkin said we started with the laws of physics. Starting at 4:57 they begin that part of the discussion.
It's already been brought up, but sure.
"The discovery, if confirmed, will also lend support to the inflation model in cosmology – the hypothesis that the universe underwent a brief period of exponential expansion immediately after the big bang"
What is cosmic inflation?| Explore | physics.org
"According to the theory of inflation, the early Universe expanded exponentially fast for a fraction of a second after the
Big Bang."
Centre for Theoretical Cosmology: The Origins of the Universe: Inflation Introduction
"Cosmic inflation is the idea that the very early universe went through a period of accelerated, exponential expansion during the first 10-35 of a second before settling down to the more sedate rate of expansion we are still experiencing, so that all of the observable universe originated in a small (indeed, microscopic) causally-connected region."
Cosmic Inflation - The Big Bang and the Big Crunch - The Physics of the Universe
"Inflation is a general term for models of the very early Universe which involve a short period of extremely rapid (exponential) expansion"
Inflation for Beginners
"Inflation is the mysterious force that blew up the scale of the infant universe from sub-microscopic to gargantuan in a fraction of a second."
Cosmic Inflation: How It Gave the Universe the Ultimate Kickstart (Infographic)
Note that in every definition, inflation is about the rapid expansion of the universe after the energy which expanded already existed.
Note further that in a couple of the definitions it describes it as happening after the Big Bang. Apparently the Big Bang is defined slightly different by different people, as I mentioned earlier.
I am reposting this.
I think the problem is that you are confusing the big bang singularity with the beginning of space and time. The big bang singularity is where Friedmann's solutions to Einstein's field equations yield infinities. That's just a mathematical thing. Inflation theory explains how matter and energy were created from nothing. So logically that occurred before the so called big bang singularity.
I think of the big bang as the beginning of the expansion and cooling. Inflation is the build up of energy and matter before the expansion and cooling of the universe.
Well, I just gave you definitions of inflation from multiple sources indicating that you are incorrect about what it entails. I'm not sure what else to say. It's just a matter of mislabeling.
Just consider the name inflation. To inflate is not to create, it is to expand. A balloon can only be inflated after the balloon exists.
Inflation theory explains how matter and energy were created from nothing through a quantum tunneling event without violating the law of conservation. It has absolutely nothing to do with the expansion and cooling of the universe.
The big bang singularity is where Friedmann's solutions to Einstein's field equations yield infinities. That is the point where all matter and energy occupied the space of 1 billionth of 1 trillionth the size of a single atom. At this point in the timeline all of the matter is in place and then it began to expand and cool.
But if you want to characterize it that the big bang came first and then inflation occurred, please do so. That makes no sense to me. If people are characterizing it that way, I believe they are characterizing it wrong. Inflation theory was discovered after Friedmann's solutions to Einstein's equations so I can see how confusion occurred, but Friedmann's solutions to Einstein's equations never explained how matter and energy were created. Inflation does.
You are displaying signs of delusions of grandeur
Delusion of Grandeur
By
John M. Grohol, Psy.D.
A
delusion of grandeur is the fixed, false belief that one possesses superior qualities such as genius, fame, omnipotence, or wealth. It is most often a symptom of
schizophrenia, but can also be a symptom found in psychotic or bipolar disorders, as well as dementia (such as Alzheimer’s).
People with a delusion of grandeur often have the conviction of having some great but unrecognized talent or insight. They may also believe they have made some important discovery that others don’t understand or appreciate.
Less commonly, the individual may have the delusion of having a special relationship with a prominent person (such as being an adviser to the President). Or the person may believe that actually are a very prominent and important person, in which case the actual person may be regarded as an imposter.
Grandiose delusions may have religious content, such as the person believes he or she has received a special message from God or another deity.
Sometimes, in popular language, this disorder may be known as “megalomania,” but is more accurately referred to as
narcissistic personality disorder if it is a core component of a person’s personality and identity. In such disorders, the person has a greatly out-of-proportion sense of their own worth and value in the world. People with this issue can also sometimes have a taste for the finer, more extravagant things in life.
Sometimes drug use or abuse can intensify or bring on episodes of delusion of grandeur. People who take phencyclidine (PCP) or amphetamines are especially at risk. People who are high and experience a delusion of grandeur may be at increased risk for physically harmful behavior. For instance, if you believe you are capable of flying after taking PCP, and try to jump off a 10-story building based upon that false belief, you may be at serious risk of death.
