Does time exist?

The Sun runs on a multi-year cycle of 11 years, IIRC.

No. In general, the day and the year of all planets.
The rotation and translation of all stars.

The rotation of the galaxies.
The rotation of the local group of galaxies.
The rotation of the local super group of galaxies.
The amount of time it takes a neutron to orbit an nucleus.

Seriously, don't think small.

How will you determine midnight?
How will you determine midday?
Of what use is a time unit that is continually changing?
How can you use a unit that is different every time you measure it?

And of what use is a time unit that takes an entire day to elapse?
Great. You can measure things that occur over weeks and months. But can you measure how long a rock takes to fall, or how fast a gazelle can run?

Wow! That gazelle ran one hundred yards in ... (carry the one, round off) 0.000011905 days!

 

So the speed of light (constant in a vacuum) is not then a light year (more precise than any planet year) MORE natural
I don't know what you are on about but I respectfully suggest you go and read up on some respected science articles about time (about time you did)

So the speed of light (constant in a vacuum) is not then a light year (more precise than any planet year)

Seriously, don't think slow

Do you blame the education system or is it just him?

man made

 

A "light-year" is a measure of distance, just like "parsec". Sorry, Han.

 

In Physics time is the measurement and the measurement was an invention by humans .

 

Patrice Dassonville then puts forward a general definition of time, as “a concept
corresponding to what separates two states of a system”. He then examines the
etiology of aging, distinguishing between biological and chronological age. The
physical inexistence of time is linked to the fact that time has no source

The Invention of Time and Space by

That is an interesting definition of time, is there any math to go with that?

 

Reference, please.

Yes time dilation is in trouble lol

Humans invented the clock and any consequence action or theory about the clock can only be invented also.

 

I have never said that the duration of the day is constant.
I have just said is natural.

 

I agree, but a light-year is a measure of distance, not time. Walk it or fly it, it's the same length.

 

A day is a general term for a period of light and a period of dark that is a result of one rotation of the Earth.. We give this day a measurement and divide the measurement into increments. A day on Earth is a variable and our rotational clock speed of the Earth is a variate and our other clocks are also a variable. However an Earth day is not the same as the constant day of space.

 

A light year (ly) is t/dx of the speed of light. It is a velocity.

t is time
d is distance
x is vector

 

A light year is defined as the distance light travels in 1 year. This is approximately 300,000 km/sec x 60 sec/min x 60 min/hour x 24 hour/day x 365 days.

 

No but the book is very detailed and while I never considered to question his conclusion about time now that you brought it up, and I have given it some thought, I am at a loss to see how he would require / use maths to prove time does not exist

I have put forward my tiny version in this arena and another forum where I keep getting asked about time travel

This is part of my tiny respond

1/ Time itself does not exist

2/ The past does not exist

3/ The future does not exist

NOW is the only moment in existence

There is some one here in one of the threads who says he is living in the future. I'm waiting for him to answer a post I sent to ask him how far into the future he thinks he exist

We ALL live in NOW not in any other moment

So, we're 7,000,000 miles per hour from the nearest star?

I don't think we're going to get him off that track.
