Black Holes

Regions of spacetime where gravity is so strong that nothing, not even light, can escape once past the event horizon. Formed from collapsed massive stars, they warp space and time in extreme ways predicted by Einstein's general relativity.

How similarity is calculated

Each concept is converted into a 768-dimensional vector using the nomic-embed-text model. Similarity scores are calculated using cosine similarity—measuring the angle between vectors. A score of 100% means identical meaning; lower scores indicate decreasing semantic relatedness.
