Black Holes aborning

No need to wait that long to paddle out and surf these gravitational waves. It's only about 1,600 light years away. I've got a hot little hybrid bussard ramjet with antimatter annihilation boosters parked at L5 that I can let you have for a song (cash only - given the time dilation effects, you can appreciate that lease payments will be problematical). At 2G continuous acceleration you can be up-close and personal at this system inside of 10 years (ship time). Carve a close tight looping gravitational assist around this white dwarf pair and you'll be on your way back for a continuous 2G deceleration and coasting to a stop back home in around 20 years from now (leave the keys in the ignition). Of course, 4,000 years or so will have elapsed on earth, so you'll want to leave a few conservative investments behind.
