I appreciate the honesty. Best of luck as this will crash eventually.

About 300 years.

I said that now I understand that negative mass cancels the positive one from KE. Problem solved. In all honesty, how old is this mess?

The thing you create negative mass with. I now understand. Thank you!

Negative energy. I cannot unsee that one. Enough! A nice day to you all.

That is correct. The scenario they are analyzing is different from the scenario you are asking about. Their paper, as I have already...

Dale's: So box starts out as m and an unspecified hard wall plus gravity from another source, Sun starts to attain kinetic energy losing...

I do understand the mass conservation problem, but this does not explain what happens to m, M and the 24% solar mass equivalent energy...

I explicitly avoided radiation leakeage by stopping the problem right before the merger. And ask what the weight of the box is initially...

True, sorry for the hasty reply. I mean to say that in your reference you would measure a higher total gravity of the moving Sun but...

Interesting. Would we agree about the same time-frame in which said gravity acts in the Sun's reference frame?

According to the MTW's Gravitation, I understand that there is no defined meaning of mass of the system in question as an absolute...

We already know that mixing Newtonian gravity and SR is problematic. That's why GR was developed.

I only used Newtonian for the energy calculation, but honestly any value of KE is already problematic, so it does not matter. I do not...

Newtonian physics has conservation of mass. In SR, we have conservation of invariant mass (for a closed system). But not...
