Rather than interpreting antigravitational motion as merely a consequence of a positive cosmological constant, it should be understood as a repulsive gravitational interaction—a manifestation of positive kinetic energy arising from the negative effective mass of dark energy or negative apparent mass, as described in ECM. This perspective fundamentally shifts the interpretation of cosmic acceleration, moving beyond Λ as a fixed parameter in GR to a dynamic force-based explanation within ECM.

Dear Mr. Stefan Bernhard Rüster

You initially addressed this discussion thread by stating: "Antigravitational motion (i.e., a repulsive gravitational interaction) is given by a positive value for the cosmological constant."

In response, I have already clarified: "Rather than merely interpreting the cosmological constant as having a positive value, it should be understood as a manifestation of positive kinetic energy arising from the negative effective mass of dark energy or negative apparent mass, as described in ECM."

This discussion thread is specifically dedicated to "Antigravitational Motion and the Gravitational Potential of the Universe," and therefore, any continuation of the discussion should remain within this thread rather than being redirected to another discussion such as "Scientific Credit and Historical Justice: Re-evaluating the Cosmological Constant."

The latter thread focuses on a different topic and is extraneous to this particular discussion.

As such, unless you choose to further engage with this topic here, my previous response effectively concludes this discussion.

Best regards, Soumendra Nath Thakur
