ScienceAlert<\/a>, he said:<\/p>\n\u201cI was looking for some completely new way to study black holes and I realized that an interstellar mission to the closest\u00a0black hole\u00a0is not unrealistic \u2013 but nobody had ever proposed it.\u201d<\/p>\n
There are plenty of reasons why nobody has proposed it. First, even if a craft is able to get up close to the black hole, it would still have lots of limitations. Since black holes are so massive that not even light can escape, looking at them wouldn\u2019t give much information. Also, if the craft flew past the event horizon, it could not transmit information back out. That being said, however, having a craft as close as possible to the black hole would still offer a treasure trove of new details.<\/p>\n
Sending a spacecraft is going to be a massive obstacle. The closest black hole that we know of is about 1565 light-years away. This means that even if we could make a craft that could travel at the speed of light, it would take 1565 years to get there and then another 1565 years to send any information back. Needless to say, that is just too long.<\/p>\n

Using modern techniques, however, it is possible that astronomers could find a black hole that is much closer to Earth. Bambi explains:<\/p>\n
\u201cI think we just need to be \u2018lucky\u2019 and have a black hole within 20 to 25 light-years. This is not under our control, of course. If there is a black hole within 20 to 25 light-years of the Solar System, we can develop the technology for such a mission. If the\u00a0black hole\u00a0is not within 20 to 25 light-years, but still within 40 to 50 light-years, the technological requirements are more challenging. If the\u00a0black hole\u00a0is at more than 40 to 50 light-years, I am afraid we have to give up.\u201d<\/p>\n
Finding a black hole this close to us is one big obstacle, but designing a ship to go to it is another. Nothing we currently have available could come close. There are known technologies, however, that could make it a possibility. For example, it is theoretically possible to build a spacecraft that gets its initial speed and trajectory from Earth-based lasers, and then picks up more speed from solar power. If it works, this craft could travel at up to a third of the speed of light.<\/p>\n

If the black hole is 20 light years away, that means the craft would arrive in a little over 60 years (accounting for acceleration and deceleration). Tack on some time and then another 20 years for any data that it transmits back to Earth and the astronomers are looking at a total mission time of about 100 years.<\/p>\n
So, while it isn\u2019t likely that anybody working on the project today (or even their kids) would be around to benefit from the mission, our ancestors would undoubtedly appreciate the effort.<\/p>\n
In addition to the main focus of the mission (studying the black hole), these types of ambitious projects often lead to other technological advances that could be used to further benefit space exploration for generations to come.<\/p>\n
