The center of our galaxy is 30,000 light years away. Could a person possibly travel there in her own lifetime?

A) No, because a person cannot travel at lightspeed. B) No, because the trip would take longer than 30,000 years, and nobody lives this long. C) No, because time dilation applies only to clocks and not to biological phenomena such as a person's lifetime. D) Yes, by traveling at nearly lightspeed, because of time dilation or the "relativity of time." E) Yes, by traveling faster than lightspeed, because of time dilation or the "relativity of time."
