----------------------------- 1992 - It is about TIME
-
-
-- The General Theory of Relativity merges time with space.
-
- Space is the geometric relationship between observable particles. Maybe it is entirely separate from time? Space is a 3-D geometry. Time is just something we preserve because the Universe is constantly changing snap shots of space.
-
- All the laws of physics treat time as asymmetrical. Mathematically time can move forward of backward. Except! Thermodynamics 2nd law of entropy. Particles and energy always move in the direction of greater disorder, greater randomness.
-
- Somehow forward time must be linked to entropy? A new theory puts increasing entropy as caused by increasing ‘ quantum entanglement”.
-
- If entropy is always increasing, then running it backwards, the Big Bang must have been the lowest entropy, or greatest randomness, or greatest amount of disorder, and therefore the maximum entropy. Entropy has been increasing ever since.
-
- Rather than trying to separate space and time maybe we just put them on an equal footing . Particles can exist at one location and not another. Maybe particles can exist at one time and not another. Space and time are equal “ quanta”.
-
- Quanta are waves and particles and what ever is in between. At the fundamental level the Universe is made up of quanta: mass, charges, momentum, etc. These fundamentals work together to create protons, atoms, molecules, and whoever is reading this.
-
- Isaac Newton came up with laws that had the world that was flat, with empty, and absolute space. Space was always fixed with 3 dimensions Time was absolute, always traveling at the same rate. This world works just fine today as long as you do not travel to the edges.
-
- Albert Einstein changed all that. Time was not absolute, it was relative depending on motion. Particles that travel close to the speed of light experience time differently. Times dilates and space contracts. Space and time are frame dependent depending on your motion.
-
- A “light clock” , due to the constancy of the speed of light, would run differently for observers moving at different speeds. Observed time is a variable. Distance divided by time is a constant.
-
- Quantum Field Theory uses “flat space”. General Relativity uses “ curved space”. The difference in Einstein’s discovery is that gravity and acceleration motion are the same thing. You can not tell the difference.
-
- Curved space uses “ Metric Tensor” math, invented by Riemann , it defines curved space-time due to gravity. How our Universe is curved defines how matter and energy will move through it. The curved space-time is called the geodesic. It is the path taken with constant motion, but, it is not a “straight line”, although , it is the shortest distance between 2 points.
-
- We did all this just to show you how gravitational lensing works to see the edges of the Universe.
-
- It is more complicated. Metric Tensor math is more complicated than just gravity. The calculations include 16 different components including radiation pressure, vacuum pressure, pressure due to motion in 3 spatial directions, volumes changing, tidal forces, and gravitational waves , to name a few.
-
- If you know the numbers for all 16 components you could predict the future of the expanding Universe. Each of the 16 components unfolds into the next frame of time. One frame after another. We are still working on the physics to describe “time”. Physics is the study, the science, that tries to describe our world. It is interesting that the more we learn the more mysteries we uncover.
-
- Time will tell.
-
- But, there never seems to be enough of it. Sorry , my time is up.

-
- Here are some quotes from previous reviews about time, each review available upon request if you are interested:
-
- Review # 1774 - Time is a fundamental concept that Quantum Mechanics and General Relativity disagree about.
-
- “It’s about time”, that we are trying to learn about time.
-
- Time, we can’t live without it.
-
- If time is an illusion, it is a very pervasive one.
-
- God created time to prevent everything from happening all at once.
-
- Review #1758 - We see time as a constant march into the future.
-
- Astronomers see time as a variable that depends on gravity and the speed of motion. Speed is space divided by time.
-
- GPS only works because equations use the Theory of Relativity when calculating distance that triangulate your position.
-
- An event that might be in the undecided future of one observer may have already occurred in another observer’s past.
-
- The act of the observer appears to prompt nature to decide what actually happens.
-
- #1735 - Time is only strange if you think about it.
-
- Mass is simply a concentrated from of energy.
-
- Gravity is the curvature of space and time.
-
- The speed of light is always the same regardless . It must be the same for all observers.
-
- #1691 - Time moves slower as you move faster.
-
- #1621 - Everything you see is younger then when you see it.
-
- #1341 Was time first created in the Big Bang? Or, did it exist before then?
-
- #1189, #1006 - No two times are the same if they are separated in space.
-
- #910, #854, #842 - To go from GPS time to Universal Time just add 19 seconds.
-
- #830, #814 - 10^-43 seconds is the smallest increment of time. A quantum of time.
-
- #783, #747 - Why 60 minutes?
-
- #356 - Zepto-seconds used to study the motion of atoms.
-
- #354 - The Universal Calendar of all events starting at 10^-43 seconds to 80,000 years. It is 60 ages long.
-
- #37 - Deriving the Time Dilation equations using the Pythagorean Theorem.
-
- #1992 - Time - It is about “time” that challenges our thinking about time
