I have a small hobby of reading about and studying physics. Finding physics examples in everyday life is fun, and drives my wife crazy when I point it out. :lol: she just stares at me....

But this article is pointing toward what may be a real answer to a problem...... I hope they learn something.

Btw, dark matter is a joke......:headbanger:

Great article. Thanks! I'm a science junkie as well. Amazing to me is that all the forces in the universe and how they interact with us in the physical world were created at the Beginning and do not change. However, the next "Big Bang" may create a completely different universe with different gravity and atoms.

Isn't dark matter basically the modern day "ether?"

YouTube has a ton of great physics, chemistry, math, science videos. This is pretty cool.

Well, physics are what we know on Earth regarding our nature and surroundings. Our physics we know on Earth don't exactly or easily extrapolate to the rest of our entire galaxy.



Space is an entirely other subject without gravity and devoid of temperature.


I love living in the Midwest and I can look up in the sky at night and see an array of stars. Thousands that I can actually see much less the other billions out thare. Kind of puts you in your place, but also makes you appreciate the greatness of what we have.

The entire universe is full of gravity, and it acts in a common manner.

Agreed. Whenever we don't understand something, we make something up. Dark matter smells like that.

Not quite. I think what might be "closer" to the Newtonian classical physics "ether", might be on the sub atomic quantum level.

"Closer" used loosely

There is the concept of "virtual" particles and "quantum fluctuation", where things on the quantum level pop in and out of existence. A concept based on Werner Heisenberg's uncertainty principle.

This allows the creation of particle-antiparticle pairs of virtual particles. The effects of these particles are measurable, for example, in the effective charge of the electron, different from its "naked" charge. Amazingly the Casimir effect demonstrates this experimentally.

The typical example is of the two uncharged conductive plates in a vacuum, placed a few nanometers apart. In a classical description, the lack of an external field means that there is no field between the plates, and no force would be measured between them.[8] When this field is instead studied using the quantum electrodynamic vacuum, it is seen that the plates do affect the virtual photons which constitute the field, and generate a net force[9]

Sort of implies that creation of reality is not yet finises. At any one instant in time, roughly 1/2 the matter in the universe exists ant the other 1/2 does not.

I guess flux as in "quantum fluctuation" is a god description

Physics is definitely the bonding force in the universe. I'm far from convinced however that physics holds all the answers to what we do not understand about it. Astronomy is still based largely on theory and actual observation.
Btw..I sold my home on Lake Livingston and moved to Riverside near Huntsville. Didn't buy, but went with a 1 year lease since the house is within walking distance of the Trinity River. Three days later massive flow from Dallas area arrived and the river sent me 10 inch deep water thru-out home. I'm helping the owner repair the damage now. First time house flooded since 1978 when it was built.
I actually feel lucky having not completely moved in. Owner still wants to sell it. Hmmm...okay, good luck with that.

"I know that I know nothing" is a saying derived from Plato's account of the Greek philosopher Socrates. It is also called the Socratic paradox.

Things that make you hmmm.
 

Using a see-saw to explain gravity and orbits.


Our Earth does not orbit the Sun (technically). Jupiter does not orbit the Sun at all... in no way does the planet Jupiter Orbit our Sun.

All objects with a mass have gravity and all things with mass orbit the common mathematical center of the nearest more powerful object. Hence why our moon orbits earth and not the sun.

Jupiter orbits a point that is just outside the Suns Surface. ( 1/1000th of the distance between the Sun and Jupiter)

Earth orbits a point that is just outside the Sun's Center.

When two bodies of equal mass are gravitationally locked, they do not orbit at all. They wobble because the common center of mass is equal distance from their center.



To understand this, imagine the person on the right is the Sun, and the person on the left is the planet Jupiter.

The 40 pound Jupiter on the left Orbits the point of the Center Of Balance between the 160 pound Sun and its 40 pound self.

This also helps understand why most orbits are elliptical.

This Video explains it visually. 1 minute 30 sec.



Another Hmmmm..
Knowing that an object orbits the gravitational center of the larger body, it then raises the question... What does our Sun Orbit?

We theorize that Our Sun orbits the Black Hole at the center of the Milky Way Galaxy.
Using the earths estimated age of 4.5 billion years.

• The Suns orbit around the Black Hole is ~225 million years

• 225 million * 20 =four billion five hundred million

20 full orbits to our 4.5 billion full orbits.

That indicates that our Sun is very young in Astronomical terms.

No. It doesn't.

Our universe/galaxy/etc is still expanding. There is no center for everything to orbit around.


The only orbit is the nearest huge object. For us. That would be the Sun.
