In practice, we could probably only manage a few percent of light speed, and even that would take an enormous amount of energy and would mean hundreds of thousands of years of travel time.  That's quite a commute. Wink

This is why there must be a dimension of travel that we have not yet fathomed.  Smile

Sending frozen embryos to be raised by androids might work. At some point we might even send digitized genomes plus synthetic zygotes. Seven billion genomes easily fit on today's hard disks.
