1) space is expanding at an increasing rate, therefore things are getting farther from each other and therefore increasing in velocity. 2) the faster an object moves relative to another, the more mass it has 3) supermassive objects can turn into neutron stars, black holes, etc. Therefore, will this effect of space expanding cause this to happen to objects?

A sub question is if two objects are now traveling towards one another, given enough time under the effect of expanding space, will they travel towards one another but never reach one another, or will they eventually appear to reverse directions from one another because space is expending so fast? Does it depend on the reference point?
