How to tell the difference between a regular black hole and a wormhole

Physicists have worked out how to see whether a black hole is actually a wormhole that could theoretically be travelled through 鈥� but we can鈥檛 tell yet with the black holes we have observed

This image shows the Atacama Large Millimeter/submillimeter Array (ALMA) looking up at the Milky Way as well as the location of Sagittarius A*, the supermassive black hole at our galactic centre. Highlighted in the box is the image of Sagittarius A* taken by the Event Horizon Telescope (EHT) Collaboration. Located in the Atacama Desert in Chile, ALMA is the most sensitive of all the observatories in the EHT array, and ESO is a co-owner of ALMA on behalf of its European Member States.
