Inflation

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.
