Time can't exist without matter (mass) and motion

Click For Summary
SUMMARY

The forum discussion centers on a thought experiment proposed by a 13-year-old user named Lakshya, which aims to demonstrate that time cannot exist without mass and motion. Lakshya derives that the rest mass of a photon is zero using the equations E=mc² and E=hv, concluding that if all matter were at rest, time would cease to exist. Several users engage with Lakshya's ideas, providing constructive feedback and emphasizing the importance of understanding the principles of special relativity, particularly that photons cannot be at rest. The conversation highlights the interplay between mass, motion, and the perception of time.

PREREQUISITES
  • Understanding of Einstein's mass-energy equivalence (E=mc²)
  • Familiarity with Planck's equation (E=hv)
  • Basic principles of special relativity
  • Knowledge of quantum mechanics, specifically the de Broglie hypothesis
NEXT STEPS
  • Study Taylor & Wheeler's "Spacetime Physics" for insights into special relativity
  • Explore the implications of the de Broglie hypothesis in quantum mechanics
  • Research the concept of null-like point-of-view in thought experiments
  • Investigate the relationship between mass, energy, and the speed of light
USEFUL FOR

This discussion is beneficial for students of physics, particularly those interested in relativity and quantum mechanics, as well as educators seeking to encourage critical thinking in young learners.

hey guys..im Sudhir and i am new to this and HI lakshya.im 14 years old! i really love astronomy and beyond SCIENCE and i know That the plaussible theory of everythin is string theory. however, due to the condridations of the mathemathics t hasnte been proven. i don't know the math behind the string theory, but do believe that i have the general ansewr to the theory of everyhitng. in fact it is simpler than the theory of relativity..

I havnt covered this bit yet but can you ever in any instance stop a photon moving?

Well, there is the question of what happens to a photon when it is re-absorbed. Is the photon still independently extant in the electron post-absorption? You can bring an electron to relative rest, so maybe the photon is resting too. (more probably pacing in it's cell.)

Photons r never at rest and maybe tats y thet dnt have mass

{If this needs it's own thread, no problemo}

It occurred to me while reading this thread to ask about 'when' a photon is generated.

Let's say we have a radio station, and it's frequency is one cycle per second. They have been on the air for 2 seconds. How far away has the radio signal propagated in that time?

Well right now I am not going to use the standard based model of space/time. By your statement you would say that every particle in the universe is vibrating at a certain frequency in order for time to exist it would need mass hence space/time. space/time's basis is on the ability of an object to be at motion, Newtonian mechanics state "Every object in a state of uniform motion tends to remain in that state of motion unless an external force is applied to it." But if this law is true it would then revoke the fact that motion is the basis of space/time. But einstein's theories were mainly based on a photon's speed being the cosmic limit. But i propose hypothetically, what if the cosmic limit is proportionate to the expansion of the universe and that it is just the constant so it would be Cosmic limit = k x rate of expansion (which k is the constant and is light in this case c ) . Our perception of time may not be accurate as we only experience time in a forwards motion. I also assume that there are tachyonic particles (When making light relative to the cosmic limit) as we live in a megaverse not a universe so i would assume they are particles faster than our universe's cosmic limit. If any flaw is noticed please make me aware as I am only 14 and i am just hypothesising.

Well your statement and references to E=mc^2 may be true but it doesn't mean or prove in any way that everything will vanish the object may just come to rest the speed of light may also not be the comic limit we assume einstein is correct but I am sure he may not be. if any particle is able to use a multidimensional shortcut it would still be considered faster than the speed of light and to a 4 dimensional space /time they may be creatures who are able to manipulate time as time is linear. I would assume that antimatter can oppose gravity or that anti matter may be able to move in reverse motion . If there are any flaws in my thoughts please show me as i am a novice only 14 :)
