In a galaxy far, far away, two giant black holes appear to be circling each other. 🌌 Gravity is causing this spiral, which will result in a collision and formation of a single black hole, a massive event that will send ripples through space and time. The collision itself happened eons ago — the two black holes are located about 9 billion light years from Earth. Scientists won't be able to document it for 10,000 years. Even so, there are imperceptible gravitational waves generated before the collision that are hitting us right now. These waves from the black holes' activity will increase, but will not affect Earth. However, they could help increase our understanding of how our universe has evolved. 📸: Caltech/R. Hurt (IPAC) 🔗: Click the link in our bio to learn more about the collision and its significance.
