[General] Is there an alternative to time travel that accomplishes the same goals that time travel does?

Dimension Hopping

Some attempts to change history / set things right only end up creating an alternate timeline, not changing the origin time line.  This prevents paradoxes, but really does not change the situation for the traveler. 

Dimension hopping will allow many people to observe a historic event without altering history by having thousands of onlookers, just making thousands of timelines that may converge back together soon after.   

Dimension hopping also handles traveling into the future, since its traveling into alternate possible futures.  Someone returning to the present with future knowledge only would know what might happen, not what will.  This allows the traveler to take action, instead of being locked in.
