I'm referring to Hawking radiation - I'm not sure if 'The only way you are likely to be able to spot a small black hole is by its gravitational effects.' is true for such close black hole since small black holes are hot (that is emit black body radiation of hot object). | |

| Jul 20, 2021 at 8:56 | comment | added | Deschele Schilder | @MaciejPiechotka What do you mean by a 100 year black hole? Are you referring to Hawking radiation? | |
| Jul 20, 2021 at 7:53 | comment | added | Maja Piechotka | A 100 year black hole seems to have peak emission in 0.1 TeV. Wouldn't we detect a strong source of radiation which is getting stronger? Also I would imagine gravity wouldn't be our only problem... | |
