Cosmos/Universe

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

 

…………………………………………
If the electric repulsion between protons were just a bit stronger, then our familiar atoms, and hence chemistry, and hence life itself, could not apparently exist.

 

…………………………………………

We might be the product of design, coincidence, multiverse or evolution.

…………………………………………

Some particular properties of the universe keep up our very existence as living, conscious beings.

…………………………………………

A man is an arrangement of dust on one small planet out of billions of trillions in  a universe, which might again be one of many universes.

 

…………………………………………

Only a thinking man  gives  meaning to an otherwise nonexistent universe.

…………………………………………

No ‘right now across the universe’  exists.
…………………………………………
“Everything we do in science is conditioned by the way we look at the world and the way we look at the world is necessarily limited.”

-Marcelo Gleiser, a theoretical physicist

…………………………………………

We can never look at the universe from the “outside.”

 

…………………………………………

 

HUP represents the most fundamental initial ‘imperative’ for the universe to exist.

…………………………………………

Methuselah is the oldest known star in the universe.

…………………………………………

According to measurements of the expansion rate of the universe, based on Einstein’s theory of General Relativity, the universe was born through the Big Bang at around 13.8 billion years ago.

…………………………………………

The analysis of  “Methuselah star” suggests that it is 14.5 billion years old – some 700 million years older than the universe!

…………………………………………

“Methuselah star” contains very little iron, suggesting that it had formed before the element became available in the universe.

…………………………………………

In understanding universe, we’re like dogs whose brains are too limited to grasp the fact that when we switch the positions of containers, we also switch the positions of their contents.

…………………………………………

If NOTHING existed before the universe came into existence 13.8 billion years ago, it was an effect without a cause.

…………………………………………
Quantum physics states that the non-universe(zero energy plus zero change) doesn’t exist because simultaneous measurement of a quantity and its rate of change is impossible. In other words, the more accurately you know the location of something, the less accurately you know the speed.


According to HUP, there is always some non-zero probability for our universe to come into existence. ………………………………………… Our universe is a symmetric deviation. …………………………………………
There is no physical universe, only a formless flux of snailpaced sensations. ………………………………………… There is no physical universe, only a flux of interpretations. …………………………………………
………………………………………… There is no physical universe, only a formless flux of snailpaced sensations. ………………………………………… From ‘zero’ to ‘infinite’ – all energy values are quantum-mechanically(HUP) superposed to represent a multiverse. ………………………………………… Our particular universe might not be an accidental one.

An organism is lucky enough to belong to a logical process called ‘cosmos’.


COSMOS might be a lowenergy and thereby longlasting quantum fluctuation due to Heisenberg’s Uncertainty Principle identical to the existence of virtual particle pairs, virtual black holes and spacetime foams within 10^-44 seconds or 10^-35 meters.

Nothingness is equivalent to some completely undifferentiated stuff (fundamental fields? ) spread out infinitely without bound.

…………………………………………
“Universe” is a translation of “quantum field excitation lasting enough to evolve into composites like us.”
…………………………………………
Energy-time uncertainty principle means that in a small enough amount of time, a particle of any energy can appear and disappear without anyone knowing outside of that time scale.
…………………………………………
Any field can have excitations in the vacuum, and those excitations might be short lived, but they are there.
…………………………………………
Most people think of a vacuum as nothing, but the fact is that the vacuum of space is loaded with quantum fields, which produce quantum foam.
…………………………………………
There are no particles and no waves; just fields.
…………………………………………
The knowledge of an indifferent universe strengthens our emotional bonds.
…………………………………………
Planckian spacetime  is literally eternal.
……………………………………..
The most likely way to get the big answers is to engage with the universe as a whole.

…………………………………………
A coherent story about the universe not only predicts  experiments, but also  explains the physical properties that made atoms, planets, rainbows, and people.
…………………………………………
We inhabit and observe a large scale universe.
…………………………………………
Our universe ,a locally inhomogeneous asymmetry , belongs to a globally homogeneous symmetry. It resembles a bubble in water.Our universe is not a thing but a pattern. It is a signal emerging from noise.
…………………………………………

 
An inflationary scalar energy field => quantum fluctuations=> rapid expansion of a tiny patch up to macroscopic scale=>  the field settled  into a lower energy state by decaying into particles, radiation and continued expansion of the universe => quantum fluctuations grew via gravity to form galaxies and clusters of galaxies.
…………………………………………
Where did the laws of physics come from? Why are there four main forces? Who decided that? Why is the speed of light 300,000 kilometers per second? Why is the electron mass 511 keV?
Why is the universe orderly anyway? Why is the speed of light always the same?

Edward Tryon dared to suggest that the Universe appeared “out of nothing” due to a “quantum fluctuation”.

“I offer the modest proposal that our Universe is simply one of those things which happen from time to time.”

Cosmology is still very speculative as to what happened before the Big Bang.

……………………………………..

There are many  competing explanations behind the Big Bang.

……………………………………..

The big bang might be  1) one time the emergence of  space and time from nothingness; 2)one of  the collisions of stringy membranes; 3)one of the  endless self-sustaining cycles of contraction and expansion; and 4) ?

……………………………………..

The Big Bang might not be the literal beginning.

……………………………………..

Our physical universe is just a linguistic translation of ‘a formless flux of  snailplaced sensations’.

……………………………………..

Scientific cosmogonies  are supported by good reasons and evidence.

……………………………………..

There is no obvious place in scientific cosmogonies  for meaning.

……………………………………..

What we now know of the mechanism  of the universe undermines our previous certainty about meaning.

……………………………………..

The future of the universe  is highly speculative and was inconceivable to our ancestors.

……………………………………..

The universe might: 1) reverse its expansion to collapse into a big crunch; 2) expand into  a big freeze; 3) be torn apart in a big rip; 4) repeatedly bounce; or 5) exist as multiverses.

“The universe is made of stories, not atoms.”

—  Roger Penrose
…………………………………………

Planets, stars, moons, even the galaxy itself — are all spinning. But we are not sure about the universe.

…………………………………………
Scientists are still in confusion about the fundamental nature of the universe.

…………………………………………
CMB light  suggests that the universe is largely uniform and not spinning.
