Comment Re:49 light years... so close! (Score 1) 13
'Years' is soft-peddling it. We lack the technology to reach the nearest star to the Sun in less than 80 years, and even that is so expensive and unlikely to succeed that we'd never fund it. A 49 light year trip would take 980 years to get there, and assuming nothing critical broke enroute, it's incredibly unlikely you'd successfully beam any useful data back.
We could eventually build a fusion drive and halve that time. There's still nothing at the end of the trip to justify the investment. Telescopes are the vastly superior tool.
And no, nano probes accelerated by giant laser to near light speed are not realistic. At all.
