Reading Astrophysics for People in a Hurry
he has also written for an Alzheimers patient.
Most people are familiar with what the Greeks taught us:
EARTH, WATER, AIR, FIRE.
In his first chapter Dr. DeGrasse tells us the rest of the story.
Chapter One: The Greatest Story Even Told
In the first chapter its all about:
SPACE, MATTER, ENERGY
At the beginning the three components of the Universe were present,
"in a volume less than one-trillionth the size of the period that ends this sentence."
"The Universe was so HOT the basic forces of the Universe
that collectively describe the universe were unified."
This small volume could only expand causing the Big Bang.
What would the Ancient Greek philosophers thought of this science?
Leucippus and Democritus would have been receptive.
What does the modern American think of this science?
I have always loved physics.
As an Alzheimers patient my math skills are gone but DeGrasse
brings this information to me in way I can understand
and enjoy with wondrous amazement.
DeGrasse continues with:
and enjoy with wondrous amazement.
DeGrasse continues with:
Einstein tells us about "gravity which in the presence of
energy and matter
curves the fabric of space and time."
"Quantum mechanics tells about the small universe:
atoms, molecules and sub-atomic particles."
DeGrasse says we are still trying to figure out a unified concept of the two.
However in the present,
Astrophysicists apply both concepts with no problem.
The interplay of :
matter (sub-atomic particles)
and
energy (Photons)
(massless vessels of light energy
that are as much waves as they are particle)
was incessant.
"The universe was hot enough for these photons to spontaneously convert their energy into matter-antimatter particle pairs which immediately thereafter annihilate, returning their energy back to photons.Yes antimatter is real."
"The universe was a seething soup of
quarks
leptons and their antimatter siblings along with
bosons."
"The ordinary photon is a member of the boson family'
Leptons are the electrons and maybe the neutrino.
"there are no familiar quarks...quarks have fractional charges that come in thirds"
As the cosmos continued to cool and expand...the temperature dropped rapidly below a trillion degrees Kelvin"
No longer "hot enough or dense enough to cook quarks"
A "new family of heavy particles was created called hadrons"
"This transition soon resulted in the emergence of protons and neutrons."
"By now one second of time has passed"
since the Big Bang.
I think I will leave it there for now as I am getting tired and I don't want to make mistakes.
