There are claims that when massive objects merge some of their mass is converted to gravitational energy. Such as the following links:

What kind of macro effects, if any, could be perceived by a person with their senses without instruments if sufficiently large gravitational waves happened to hit earth, in the case of a ripple and in the case of a long term constant change (if that's even a thing, otherwise please assume a very very low frequency, which would mean a gentle slope).

What would be an example of the distances and masses involved for us to feel such effect?

  • $\begingroup$ @WayfaringStranger good point. But I'm really curious to grasp what's the effect of gravity waves interacting with everyday objects at a human scale. For example, what amount of energy could cause, say, a 1C increase in oceans water leading to global warming, ,if that were to be the dominant effect. So looking back, I'd need to rephrase the title. $\endgroup$

    $\begingroup$ Does this answer your question? How far should the source be, for the gravitation waves to be visible on Earth? $\endgroup$

    $\begingroup$ Note: the actual dislocation of an average gravitational wave is a thousands of a nucleus. $\endgroup$
