The Centauri system is 4 light years away, my link shows a proposal of how to do that with a flyby, it's most certainly not the only starshot proposal just the one with a prominent billionaire like Mark Zuckerberg behind it so I thought perhaps the best to put out there for people to see as an intro to the concept.

These are very real ideas with very real engineering designs by incredibly smart people. It's not sci-fi mate, we can actually do this with enough wherewithal.

Right.... but 4 light years is one thirtieth as much as 120. Unless you find a way around relativity I don't see how anyone alive now would get results from a mission to something 120 light years away, regardless of its velocity. Unless we vastly increase human life span, which might be the easier option.
