Doesn't successive DNA replication almost guarantee mutation?

I don't know a thing about biology, but it seems to me that we all originate from a single fertilized egg cell that divides many times to become an adult organism. As I understand it, each time this division occurs, the nuclear DNA is replicated. Since there must be MANY such replications before we reach adulthood, and since each copy is a copy of a prior copy (with the exception of the original egg cell), it seems that the Law of Large Numbers would almost guarantee that errors would be introduced in future divisions. Since these errors are in turn propagated to future generations of cells within the organism, the number of errors would compound, and if the organism lived long enough (as measured in replication cycles), that it would have all sorts of things breaking down due to increasingly corrupted copies of its 'original' DNA. Does this actually happen in higher animals, or do the bad copies usually just die off since they aren't viable? Could this explain aging (in part)?

Could time dilation be used to effectively travel forward in time?

Assume that there is some suitably strong stable source of gravitation (a black hole, white dwarf, neutron star, whatever) around which an 'oribiter' could establish a stable orbit. Would it be possible to make the orbital radius small enough so that 1) the orbiter's gamma would exceed 2, and 2) its human occupants would not be ripped apart by tidal forces, smashed by the effective gravity inside the orbiter or cooked by radiation from the gravitational source?

If this were possible, wouldn't time for people inside the orbiter pass at half the rate (or less) than it would in the 'rest of the universe' that is at rest in relative terms?

At even higher gammas, such a scheme could be used to go to future time periods by spending pre-determined amounts of time in the orbiter (essentially putting the rest of the universe on 'fast forward'). Of course, this disregards the time and energy it'd take to accelerate/decelerate the orbiter, etc.
