SUMMARY

The discussion centers around the equation (distance)(speed of light)^2 = speed of time, which is proposed to equate to m^3/s^2. Participants unanimously reject this equation, asserting that speed is defined as displacement over time, making it impossible to define time in terms of speed without creating a circular reference. The conversation also touches on the concept of "Planck time" and the distinction between "speed" and "rate," concluding that time has a rate of approximately 1 second per second.

PREREQUISITES
  • Understanding of basic physics concepts, particularly speed and time.
  • Familiarity with units of measurement in physics, such as meters and seconds.
  • Knowledge of the speed of light as a constant (approximately 299,792,458 meters per second).
  • Awareness of the concept of Planck time in quantum physics.
NEXT STEPS
  • Research the concept of Planck time and its implications in physics.
  • Explore the differences between speed and rate in scientific contexts.
  • Study the principles of dimensional analysis in physics.
  • Investigate the implications of time as a continuous versus discrete phenomenon.
USEFUL FOR

This discussion is beneficial for physicists, students of physics, and anyone interested in the fundamental concepts of time and speed in the context of theoretical physics.

Sorry, I think I made a thread in the wrong section before. I was wondering if anyone thought time could have a speed? If so, what would be its dimensions?

I encountered someone who claimed that
(distance)(speed of light)^2 = speed of time
with units, that would be m^3/s^2 = speed of time

is this possible? or is this some retarded proposal? Opinions?
 
Science news on Phys.org
the way i see it speed is defined as the distance covered divided by the time taken.
therefore speed is defined BY time:
to define time by it speed would/could create a circular reference.
[what is a fork? a fork is what goes with a knife. ok, so what is a knife then? a knife is what goes with a fork. we're not much further in finding out what a fork is!]
HOWEVER
i have wondered before if time was continuous or discreet, i.e. does the universe have a refresh rate of sorts. in my bit of digging i came across a concept of "plank time" i can't tell you anything about it though! but i thought you may be interested.
just my two €cents
 


Do you mean really "speed" or do you mean "rate"?

If you mean "speed", then no. Speed is displacement over time. Time cannot be described in this way. I cannot tell where the guy got
the equation "(distance)(speed of light)^2 = speed of time". What does he mean by "distance" and why "C^{2}"? but just to put a nail in that coffin:

(distance)(speed of light)^2 = speed of time
or
(meters)(C meters per second)^{2}=(meters per second)
the units are
\frac{m^{3}}{s^{2}} = \frac{m}{s}

As you can see, that's not true. So, you can toss it out right there.

If you mean "rate", then yes. Time does have a rate. It is roughly 1 second per second.

If you mean something other than "speed" or "rate", you should clarify the OP. Maybe that means finding that guy again...
