Undergrad I have a question about gravity -- If the value of the energy momentum tensor (Tμν) becomes zero, can it become gravitational-free?
Then, if the energy momentum tensor everywhere is zero, is it possible to assume that it is anti-gravity?- seonjunyoo

R μν − 1/2g μν R= 8πG/c^4T μν In this formula, if the value of the energy momentum tensor(Tμν) becomes zero, can it become gravitational-free?- seonjunyoo

High School I wonder about a particle's energy when mass is obtained or lost
According to Einstein's formula, energy is generated when mass is obtained or lost. What does losing or gaining mass mean for an atom or particle valence? It's simply because of the formula I don't want this kind of answer I want. What does it mean for an atom or particle to lose or gain mass...- seonjunyoo

High School I have a question about energy & ignoring friction losses
If the energy itself ignores loss resistance friction and the energy moves forward, can infinity go far at a constant speed?- seonjunyoo

High School I have a question regarding temperature and the kinetic energy of molecules
Does the high temperature increase the kinetic energy of molecules or atoms, or does the high kinetic energy of atoms or molecules increase the temperature ? I'm so curious about this. Which concept is more accurate between the two- seonjunyoo
