Protons become more massive (colloquially: heavier) not more voluminous. Actually, due to Fitzgerald contraction, volume decreases as (assuming it starts as a sphere) speed increases into more of a disc shape. From point of view of proton, mass and volume have not changed, just going really, really fast. Also not apparent to proton but to us is that time passing for proton slows down thus allowing proton passage into future with same girlish figure and good looks intact, not like some withered bitter old decrepit...., sorry! I digress. Not sure what happens (from our point of view) if proton volume / mass ratio crosses threshhold for blackhole formation. Might have S. Hawking mull that part over. <br /><br /><br /><br />You don't know what you do to me<br />The Emotions <div class="Discussion_UserSignature"> <p><font color="#ff0000"><strong>TPTB went to Dallas and all I got was Plucked !!</strong></font></p><p><font color="#339966"><strong>So many people, so few recipes !!</strong></font></p><p><font color="#0000ff"><strong>Let's clean up this stinkhole !!</strong></font> </p> </div>
