The launch of the James Webb Space Telescope could now produce data needed to assess one of Stephen Hawking’s most controversial theories, suggesting that dark matter (the invisible substance that makes most matter in the cosmos) may be made of black holes formed in the earliest moments of the Big Bang. Web20 de mar. de 2024 · At the event horizon, Hawking realized in 1974, one particle in a pair can fall into the black hole while the other escapes. As the black hole radiates such particles, it loses energy and mass until it evaporates completely. Such "Hawking radiation" is too feeble to observe, but few scientists doubt its existence.
