Do we feel the Earth going around the Sun as acceleration?

Click For Summary

Discussion Overview

The discussion revolves around whether we can feel the Earth's motion around the Sun as acceleration, exploring concepts related to gravitational waves, free fall, and the implications of general relativity. Participants examine the nature of gravitational effects and the energy associated with Earth's orbital motion.

Discussion Character

  • Exploratory
  • Technical explanation
  • Conceptual clarification
  • Debate/contested

Main Points Raised

  • Some participants propose that since the Earth is in orbit around the Sun, we are in free fall and therefore do not feel the acceleration of this motion.
  • Others argue that the Earth does produce gravitational waves due to its orbit, albeit at low intensity, with a power output of approximately 200 watts.
  • A later reply questions the practicality of harvesting these gravitational waves, noting their long wavelength and low frequency, which would require significantly larger collectors.
  • Some participants express amazement at the gravitational wave production and share humorous takes on the implications of this energy source.

Areas of Agreement / Disagreement

Participants generally agree on the concept of free fall in relation to Earth's orbit but express differing views on the implications of gravitational wave production and the feasibility of harnessing this energy. The discussion remains unresolved regarding the practical aspects of collecting gravitational waves.

Contextual Notes

There are limitations in the discussion regarding assumptions about gravitational wave energy and the definitions of acceleration in the context of general relativity. The mathematical implications of these concepts are not fully explored.

Who May Find This Useful

This discussion may be of interest to those exploring concepts in general relativity, gravitational physics, and the implications of orbital mechanics in a humorous or speculative context.

when electron is moving around it like it accelerate and so it create magnetic field. and when mass accelerate it create gravity radiation , we also know that the gravity is not actuall force and it just change the time so when the Earth move in 4 direction it change it path because time change so the Earth no actually accelerate so I am kind of confuse do we can measure the Earth going around the sun from Earth or we don't fill it . and if so does the Earth produce gravity wave all the time ?. and if we don't fill the Earth going around the sun isn't proof the general relativity

Question to the experts: could it be said that since we're in an orbit around the sun, we're in free fall (along with the entire planet, obviously), and therefore wouldn't feel the acceleration of our motion around the sun?

Yes, exactly. There is no "proper" or "real" acceleration in this case.

I guess it answer my question as well

The action of the Earth orbiting the Sun does produce gravitational waves, but of low intensity. They have a power of ~200w. The energy for these waves come at the expense of the Earth's orbital energy, so producing them causes the Earth to fall in closer to the Sun. This is no cause for concern however, as this inward creep only happens at the rate of about 1 proton width per day.

Indeed, instead of solar panels I have 1,5 m^2 of gravitational wave panels on my roof with an efficiency of 10%, giving me a whopping 10^-21 Watt of gravitational power.😜

Patented as the "Haushofer's gravitational panel solution to the global energy crisis" 😎

I hate to be the bearing of bad news, but there is bit of a fly in the ointment. Those gravitational waves generated by the Earth have a frequency of 1 cycle per year and a wavelength of 1 light year.
So you are going to need a much, much larger collector to effectively harvest them.

You just shattered my 100.000 euros investment.

That's why the efficiency is only 10% :cool:
