Is it correct to say that an object's mass increases with its speed until it reaches the speed of light, at which point the mass is infinite?
If so, doesn't this mean that the object's gravity also increases?
As it approaches the speed of light, shouldn't the object turn into a black hole? Due to its incredible mass and gravity?
Will the size of the object matter? Perhaps a billiard ball would have to be going at the speed of light to achieve this effect, while a large planet might become a black hole at only 90,000 km/s?
Bonus Question- is my answer to this question okay? http://uk.answers.yahoo.com/question/;_ylt=Aqu4X9dggkkv2l6HRgeBg2kSBgx.?link=answer&.crumb=uHuYKTr5DcP&qid=20070102131855AAGhdnJ&.done=http%253A%252F%252Fuk.answers.yahoo.com%252Fquestion%252Findex%253Fqid%253D20070102131855AAGhdnJ
