How do we detect the presence of a black hole
WebOct 28, 2024 · Wormholes are possible, according to Einstein's general theory of relativity, but nobody has ever spotted one. The new study provides a possible way to make the first tentative detection: look for... WebBlack holes can be surrounded by rings of gas and dust, called accretion disks, that emit light across many wavelengths, including X-rays. A supermassive black hole’s intense gravity can cause stars to orbit around it in a particular way.
How do we detect the presence of a black hole

WebBlack holes don't radiate light, and an object that falls inside a black hole doesn't emit light either, so detecting them can be challenging. Just as with neutron stars, if a black hole is in a binary and it strips gas from its companion, we can detect X-rays from the resulting accretion disk (see "Observing Neutron Stars" ).
