Time Is there a clock anywhere?

Yesterday is but a memory Tomorrow is but a dream Today is the reality

As you read this sentence, from start to finish, you may or may not recognize the flow of time. Did time really flow, or was that just an illusion?

As you read this sentence, from start to finish, you may or may not recognize the flow of time. Did time really flow, or was that just an illusion? If, as you were reading it, nothing at all changed, if not the clock, anyone in the hallway, no sound, no shadow, no air, no dust swirling, nothing at all changed…then did time move on?

Is the future open and changeable, until it becomes the present?

Is the past really fixed?

J.R.R. Tolkien said that there were different levels of reality. One level of reality is that of a past which really did happen, even though it may or may not be known.

J.R.R. Tolkien said that there were different levels of reality. One level of reality is that of a past which really did happen, even though it may or may not be known. Another (second) level of reality is that which is known (or believed) by everyone, even though conflicts with the first level of reality.

Another (second) level of reality is that which is known (or believed) by everyone, even though conflicts with the first level of reality. J.R.R. Tolkien believed that the second level of reality was the only one that had validity.

Albert Einstein’s theories of relativity suggest that there is no one single piece of time, and that all moments are equally real.

Is time fundamentally real? An analogy is this…is a chair fundamentally real?

A chair ~ certainly looks, feels, smells, and acts real. Is is made of Wood and leather, which is made of

This is another quark. This is his glamour shot.

Make time, or get rid of it. Sir Isaac Newton had three great laws 1.Things like to keep doing, what they are already doing, in straight line.

Time gives it an order. The object cannot accelerate BEFORE the force is applied

Time must also have an idea, or a notion, or duration. An example is that Tony and Tina both left home for 3 hours. In order for them to meet back at the same time, an hour has to mean the same thing to both of them. An example is that Tyson is going to eat 25 chicken wings in one hour. Time has to endure for an hour to find his wing eating rate. In order to find the rate, time has to endure, even though it is in the past.

Newton said (but not in so many words), that the world exists within the confines of an enormous clock, and everybody works within that clock. That “clock” said, if Newton is correct, that time a.Has order

Assaults on the castle time. Ludwig Boltzmann (an Austrian) reasoned, and proved, that Newton’s equations worked equally well going forward or backward in time, so time must not have a built in arrow.

Assaults on the castle time. Einstein showed, in his special theory of relativity, that 1.What two people are doing at the same time depends upon the speed at which they are moving. 2.Events don’t happen in a place or at a certain time, but they happen in a union of space and time, called space- time.

Assaults on the castle time. Einstein showed, in his general theory of relativity that …. 1.If the theory of special relativity, and space- time put a heavy load on the idea of a master clock, called time, then the theory of general relativity crushed it. 2.The introduction of gravity as a distortion tool for time makes it impossible for any two clocks to be synchronized, even if they started out that way.

A summary of time, according to Einstein, would say that either a.There are no clocks in the universe or b.There are many clocks, and each works with only a very small part of the Universe, or to a particular object.

Quantum Time Quantum Mechanics says that, there are probabilities of different outcomes. 1.Time is that thing that makes the contradictions of probabilities happen. A rolled dice cannot have both the 3 and the 6 showing. Changes in quantum fluctuations must be chromatic. 2.Quantum mechanics provides for quantum probabilities and possibilities for all of space at the same time. Entanglement implies “spooky action at a distance”, and is dependent upon a master universal clock. This is why Einstein hated, hated, hated quantum mechanics

Quantum mechanics, which is 1.Tested 2.Proven 3.Gives unerringly correct results 4.The basis for computers, light science and statistical experimentation needs for the Universe to have a Master Clock General relativity, which is 1.Tested 2.Proven 3.Gives unerringly correct results 4.The basis for nuclear physics, astronomy expressly forbids a Master Clock

Do we really need time? Time is a placekeepper, like dollar bills. Our class will let out in 375 heartbeats. Light travels 240,000,000 meters per beat
