Is time static?

Physics

June 2, 2017

Question

Love your site, Thank You!

Subject: Relativity/Time
Question:
We humans understand time as past, present and future.
The Past is our Memory
The Present is our Current Condition
The Future is our Expectation

Is it possible that Time is static?

We exist in a series of static universes that we register as the duration or "flow" of time.
Even at Planck time there is duration.
Duration is change in the Universe.
By splitting any change into time segments, every change has a beginning, a duration and an ending.
Even the emission of a photon.
It is a static photon, it starts to move, continues to move and stops moving when acted upon or reaching the desired destination (Planck Length).
During the moment when it starts to move there is duration between its static point and its next static point.
There is even duration between the change of static points. Like a buildup to change similar to a potential charge of time. I'll call it a Duriton.
Duritons occur faster than can be measured by our technology. Just because something can't be measured doesn't mean it can't exist.
Our lives are a series of duritons that we register on a massive scale to simulate continuity.
Is it safe to say that we exist in a constant flow of individual duritons, remembering the past as the present?

Thank you.

Answer

The whole concept of time is difficult and complex.
As far as humans go, the sensing of time seems to vary with age. See Sensing Time. Thus, is time different for different people?

At the quantum level of matter, movement is in "quantum jumps" instead of being continuous. Likewise, since time is related to motion, it too could be in quantum increments. Thus, you could think of time being static in between those jumps. Your idea of a "Duriton" might fit within that area.

In some theories, time is considered a fourth dimension. It can curve just as space can curve.

Keep up the good work in pondering these issues.

Thoughts on Absolute Zero

Physics

June 2, 2017

Question

Subject: Energy/Absolute Zero

Question:
"At the physically impossible-to-reach temperature of zero kelvin, or minus 459.67 degrees Fahrenheit (minus 273.15 degrees Celsius), atoms would stop moving. As such, nothing can be colder than absolute zero on the Kelvin scale."

However, is there a scale that measures colder than Zero Kelvin (Absolute Zero)?
Lets call that True Absolute Zero (TaZ)

We know that matter is composed of energy and the reversion of matter to energy is the basis of the atomic bomb. If matter is made of energy then is there a scale that measures energy down to its baseline?

An electron volt (eV) is not a baseline value of energy because we measure fractions of eV. Lets call the baseline value of energy an "Eneron".

Every atom has movement within itself on diminishing scales.
Quarks, Leptons and even Bosons have movement in their spins.
Temperature is movement. Frozen means no movement. True Absolute Zero would imply that all movement has stopped.

Energy implies movement. "Its energetic"
At TaZ (True Absolute Zero) wouldn't energy stop? If an Eneron stops, is it no longer energy. Can it restart without another Eneron acting upon it?

"The first law of thermodynamics, also known as Law of Conservation of Energy, states that energy can neither be created nor destroyed; energy can only be transferred or changed from one form to another."

If the Eneron stops it is no longer energy and thus the first law of thermodynamics is wrong.

In the Universe there exists a potential for everything to eventually and completely freeze over time. Everything in existence reaches true absolute zero and all energy stops. With no energy to initiate movement (heat), there is no action to generate more energy.

Thank you

tMic - USA (28070)

Answer

The requirements for Absolute Zero are not only that atoms stop moving or have zero kinetic energy, but also that their internal potential energy is zero. In reality, the binding forces of the atoms would reach zero, such that the particles would fall apart.

Even Quarks, Leptons, and Bosons would not move or spin.

Matter is really not made of "energy". The energy released in an atomic bomb, such that the mass of the material is reduced, is in the form of electromagnetic radiation or photons. These particles do not have a rest mass, but they do have momentum as they move.

An electron volt is the unit of energy equal to the work done on an electron in accelerating it through a potential difference of one volt.

I hope that gives some explanation. Keep up the good work in creatively looking at these Physics concepts.

Question

Hi there,

I write for Pet Life Today and I’m reaching to share our guide "The State of Pet Healthcare in 2017," which explores pet health care costs and trends, common illnesses, insurance and financial aid options, and more: https://petlifetoday.com/state-of-pet-healthcare/

We've also created a custom graphic for pet owners on the most common health problems for dogs and cats with symptoms and treatment: https://petlifetoday.com/state-of-pet-healthcare/#infographic

If you like them, I hope you’d consider adding the guide or the infographic (or both) to your pet health resources page.

Thanks!

Pollyannaish drivel

Life

June 1, 2017

Question

This Pollyannaish drivel reminds me of the adage, "Cheer up things could be worse"

"So I cheered up."

"And sure enough, things got worse."

Stephen - USA (28068)

Answer

The way I remember the adage was: I was feeling down and depressed, when I heard this voice saying, "Cheer up, things could be worse." So I cheered up, and sure enough, things got worse." The first part is important.

That is a humorous view on a philosophy concerning your attitude. I believe a positive viewpoint is better than a negative one. Of course, each person can have his or her own philosophy.

Using 220 volt device in a 240 volt socket

Electricity

May 31, 2017

Question

i am wondering if you can use an electrical device rated 220 volt in a240 volt socket I live in Australia thank you.

peter - Australia (28066)

Answer

The difference in voltages should not matter, since there is about a 10% variation in both. However, if the doesn't match the socket, you would have to get an adapter.

Why is nitrogen used in tires?

Chemistry

May 28, 2017

Question

Why is it used in tires?

Allen - USA (28064)

Answer

Air is made up of 78% nitrogen, so it is already in inflated tires. Pure nitrogen has the advantage of keeping a more stable pressure in the tires over a long run. Race cars use pure nitrogen to avoid pressure changes when the tires heat up during a race.

How does hardness affect rolling friction?

Friction

May 25, 2017

Question

My question is, how does hardness of a surface influence rolling friction? Thanks

Michael - Nigeria (28060)

Answer

If the wheel or the surface on which it rolls is not hard, the coefficient of friction is increased because of a "plowing effect".

See Rolling Friction for some examples.

Question

just a comment: I and many people I know still refer to the police as 'pigs'....

campbell - USA (28047)

Answer

At one time "cops" was a derogatory term for police. Now, that term is accepted and I guess it has changed to "pigs".

Can one build a new character?

Character

May 15, 2017

Question

Been fully grown, can one still build a new character?

Do we have have an extent that character we get to then we describes it as a fully matured character?

JOHN - Ghana (28048)

Answer

You can always improve your character. You may have learned some character traits that now are not beneficial to you and your relationship with others. In such a case, you can seek to change and improve your character.

Look to people who are honest, courageous, conscientious, and helpful as examples to emulate.

Best wishes on improving your character.

Squirrel made a home in the feeder

Behavior

May 14, 2017

Question

OK, I hope this one does not stump you, but I had bought many months ago, a metal squirrel feeder with a lid, and my Wife and I have enjoyed watching them, eat, play, get closer and more trustworthy of us.

But a couple of days ago a very strange thing occurred. As I was standing on our deck looking at the squirrel feeder over on the fence, something looked odd, so I went over to look. A squirrel had climbed INSIDE, with the lid closed and appeared all curled up, either asleep or I was afraid had died. I wasn't sure what to do. I finally rousted him awake (Whew, wasn't dead), but he sure appeared afraid.

I went to prop the lid open, looking for something to use, figuring if I propped it open, he'd leave. Well minutes later I came up with something (He had plenty of time to escape while I was looking, but hadn't). While I was in the process of trying to prop the lid open, the squirrel came flying out of there, startling the CRAP out of me>>LOL.

Well I figured, lesson learned for him or HERS>>LOL. Won't do that again. Well late this afternoon, early evening, there it was again. It took me longer to prompt it to leave, and I decided to take the feeder down, and plan to give it and the near new bag of feed away.

But I am still wondering, why this behavior, why now, this one squirrel after so many months??? Didn't appear ill, because it ran like the dickens.

Steve - USA (28046)

Answer

It sounds to me like the squirrel thought it found a good home that included a source of food. Of course, you frightened the critter when you tried to prop open the lid.

We had a squirrel feeder on our back deck and supplied it with peanuts. But then one of them ate a hole in the sliding screen door and would start to come into the kitchen to beg for food. We then removed the feeder to discourage them.

They are clever little animals and fun to watch, but they can be a nuisance too.

Is attraction the same on the Moon?

Gravitation

May 13, 2017

Question

Will force of attraction between any two objects be same on the moon.

Jyotirmay - Nepal (28045)

Answer

Gravitation force only depends on the masses of the two items. The mass of an object is the same on Earth, on the Moon or in space. Thus the attraction is the same on the Moon.

However, the attraction of a single object toward the surface of the Moon is different that its attraction (or weight) on Earth. That is the force of Gravity on the Moon or Earth.
