Incorrect. A particle has mass, and cannot attain light speed. tom K0TAR Should have said "charged particle" rather than "particle". tom K0TAR You were correct the first time. Nothing with mass can attain light speed and it doesn't matter if it is charged or not. I think you need to clarify.. zero "rest mass".. Nope, "mass" unqualified refers to rest mass and qualifiers only become necessary if talking about other than rest mass. -- Jim Pennino Remove .spam.sux to reply. |
