Inspire kids to become scientists by saying that…..………………………………………………………………..

……………………………………..
The higher energy ‘state’ of the Universe during inflation is like higher ‘level’ of water in a bottle before it leaks and the said level comes down to the bottom, of course, in a low-energy state.

But if the said level can’t reach the very bottom but stops above at some upper position resembling the finite, non-zero value of the Higgs field when its symmetry breaks — it might evolve into the dark energy (inflaton field in post-inflation avatar?).

……………………………………..
Quintessence (the purest essence of something) is the generic model unifying the inflationary field and the dark energy field as a whole.

……………………………………..

Inflation occurs at an energy scale of around 10^15 GeV while dark energy at an energy scale of around 1 milli-eV.

……………………………………..

……………………………………..

After 13.8 billion years, we expect to be able to see back almost 13.8 billion light years. But the observed value is 92 billion light years because matter is gravitationally attracted , space itself has inflated ( 41.4billion ly) and is still expanding dark-enegetically(46billion ly).

……………………………………..

Matter moves through space, mostly due to the gravity.
……………………………………..

……………………………………..

Maximum non-expanding cosmic distance is twice the age of the Universe in light years. Yet there are galaxies more distant than that!
……………………………………..

Due to the Universe’s expansion and the presence of dark energy, 97% of the observable Universe is already unreachable, even if Elon Musk left today at the speed of light.
……………………………………..
New space is constantly getting created in between the bound galaxies, groups and clusters.
……………………………………..

………………
Initial and inflationary high energetic false vacuum state (field theoretically some sort of ‘inflaton’ particle) was coupled to matter and radiation. Dark energy has no such coupling.

……………………………………..
“The more existential knowledge we have, the deeper we live.”
……………………………………..
A fish in the pond should live both horizontally and vertically to attain maximum experience. To live maximally, man needs both horizontal (social bonding) and vertical (existential knowledge) experience.
……………………………………..

……………………………………..
According to Einstein’s General Relativity, a matter-packed and yet globally homogeneous universe is inherently unstable ( either expanding or contracting ) against gravitational collapse.

……………………………………..
Einstein’s relativity is the juxtaposition of two alienated but mutually influencing aspects of reality in a single equation: a matter-and-energy side, and a space-and-time side.
……………………………………..

The initial inflationary Universe was temporarily in a highly energetic false vacuum state, where it had vacuum energy inherent to space itself. It later decayed into a lower-energy state or Big Bang.
……………………………………..
Many cosmological predictions that came out of inflation, have been confirmed.

……………………………………..

Along with the race between inflation ( 10^-33 seconds ) and gravitation, dark energy(six billion years) is responsible for about 70% current cosmic expansion rate.

…………………………………………

Nature is most complex on the intermediate (human) scale between the masses of atoms and stars.
…………………………………………
Man belongs to both the cosmos and
the microworld simultaneously.
……………………………………..
……………………………………..

A man is made up of about 10^29 atoms.
…………………………………………

A man stands midway between the masses of atoms and stars.
…………………………………………
Only intelligent people know what to ignore.
…………………………………………

Our telescopes observe 10^78 atoms(observable universe).
…………………………………………

…………………………………………

Local (called ‘biological’) schemed (called ‘free willed’) actions are actually disguised (genetically-cogged in DNA or chemically-cogged in brain) past (illusorily causal) influences embedded within global (called ‘cosmic’) indeterminism (called ‘Heisenberg’s uncertainty’ ).

……………………………………..
……………………………………..
Only in the largest possible (cosmic) context, we can actually know what or why we are.

……………………………………..

Physics relates the planckian smallness (within 10^-44 seconds or 10^-35 meters) to cosmic vastness( 46.5 billion light-years inflated plus dark-energetic radius in 13.8 billion Years ).
……………………………………..

……………………………………..
We know up to the first fraction of a second after the Big Bang.

……………………………………..
Six discretely measured (not theoretically derived ) fundamental constants of physics maintain our existence. So our existence is no less suspenseful than a mystery movie.

…………………………………………

…………………………………………
Our telescopes can see a jet of plasma shooting from the central blackhole of Messier 87 galaxy ( 55 million light-years from Earth) due to the ray’s huge length(about 6000 light years).
…………………………………………

Almost all galaxies have a central black hole that periodically draws in stars and gas clouds.

…………………………………………

Falling gas swirls and heats up in massive black holes. Magnetic fields focus some of it into jets of hot plasma. Such outflows of energy from central or massive black holes stop or start the star-formation throughout galaxies.

…………………………………………

…………………………………………
According to Einstein’s special theory of relativity, no’thing’ but only ‘space’ can move(actually expand) faster than light. Yet an energy beam from galaxy M87 inexplicably(at least still) moves five times the speed of light.
