As he mentioned the problems are numerous and extremely difficult to solve. One of the problems he didn't mention was navigation. Stars are so far way that if the trajectory of the probe is off by even by a fraction of a fraction at the start of its journey it could miss its target by light years. Don't even get me started on interstellar radiation and the shielding technology we don't have.

I wonder if they have considered what happens if this 100GW beam misses it's target and shoots some unsuspecting alien in alpha centauri? It would be very hard for the aliens to see this as anything other than an aggressive act.

Moving this video to oritteropo's personal queue. It failed to receive enough votes to get sifted up to the front page within 2 days.

*promote

Promoting this video and sending it back into the queue for one more try; last queued - promote requested by eric3579.
