Define Mass: Travels Through Time?

[toastercombo]

Would it be misleading (to myself) to define mass as that which (insert a group of words like interacts with/experiences/ travels through/ is affected by/...your preference) time? That seems more useful than "that which warps spacetime."

 

[Orodruin]

Both of those definitions would be misleading.

 

[Dale]

I agree with Orodruin, both would be misleading.

Is there a particular standard definition of mass that you are having trouble understanding?
