Scientists Confirm Elusive ‘Missing Link’ Black Holes Using Gravitational Waves
Affiliate Disclosure
Hey fellow impactful ninja ?
You may have noticed that Impactful Ninja is all about providing helpful information to make a positive impact on the world and society. And that we love to link back to where we found all the information for each of our posts.
Most of these links are informational-based for you to check out their primary sources with one click.
But some of these links are so-called "affiliate links" to products that we recommend.
Why do we add these product links?
First and foremost, because we believe that they add value to you. For example, when we wrote a post about the environmental impact of long showers, we came across an EPA recommendation to use WaterSense showerheads. So we linked to where you can find them. Or, for many of our posts, we also link to our favorite books on that topic so that you can get a much more holistic overview than one single blog post could provide.
And when there is an affiliate program for these products, we sign up for it. For example, as Amazon Associates, we earn from qualifying purchases.
What do these affiliate links mean for you?
First, and most importantly, we still only recommend products that we believe add value for you.
When you buy something through one of our affiliate links, we may earn a small commission - but at no additional costs to you.
And when you buy something through a link that is not an affiliate link, we won’t receive any commission but we’ll still be happy to have helped you.
What do these affiliate links mean for us?
When we find products that we believe add value to you and the seller has an affiliate program, we sign up for it.
When you buy something through one of our affiliate links, we may earn a small commission (at no extra costs to you).
And at this point in time, all money is reinvested in sharing the most helpful content with you. This includes all operating costs for running this site and the content creation itself.
What does this mean for me personally?
You may have noticed by the way Impactful Ninja is operated that money is not the driving factor behind it. It is a passion project of mine and I love to share helpful information with you to make a positive impact on the world and society. However, it's a project in that I invest a lot of time and also quite some money.
Eventually, my dream is to one day turn this passion project into my full-time job and provide even more helpful information. But that's still a long time to go.

📰 The quick summary: Scientists have discovered at least five intermediate-mass black holes using gravitational wave data, filling a crucial gap in our understanding of how these cosmic objects evolve across the universe.
📈 One key stat: One of the newly identified black holes has a mass nearly 350 times that of our sun, making it one of the heaviest gravitational-wave signals ever observed.
💬 One key quote: “Black holes are the ultimate cosmic fossils,” said astrophysicist Karan Jani, the lead investigator and director of Vanderbilt Lunar Labs.
1️⃣ The big picture: Astronomers have finally found evidence of elusive intermediate-mass black holes, which bridge the gap between smaller stellar-mass black holes and supermassive giants. A team led by researchers at Vanderbilt University reanalyzed gravitational wave data from LIGO and Virgo observatories using advanced models and AI techniques. Their analysis confirmed at least five black hole collisions resulting in objects weighing between 100 and 100,000 times our sun’s mass. These discoveries help solve a long-standing cosmic mystery and provide insight into how black holes grow throughout the universe’s history.
2️⃣ Why is this good news: Finding these missing-link black holes helps complete our cosmic picture of how black holes form and evolve over billions of years. The discoveries challenge existing theories about where black holes can form, including finding some in the unexpected pair-instability supernova mass gap. Advanced AI techniques proved crucial in distinguishing real gravitational wave signals from background noise, creating more reliable detection methods for future discoveries. This research also strengthens plans for future space-based detectors like LISA and potential lunar observatories, which will track black holes for years before they merge rather than just capturing their final moments.
3️⃣ What’s next: Scientists will leverage the upcoming Laser Interferometer Space Antenna (LISA) mission, scheduled to launch in the 2030s, to track these intermediate black holes for years before they merge. Researchers are also exploring how lunar-based detectors with no atmospheric interference might further advance black hole detection capabilities. Vanderbilt researchers will continue using AI models to separate true gravitational wave signals from environmental noise for more accurate findings.
