  • $\begingroup$ 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... $\endgroup$

  • $\begingroup$ @MaciejPiechotka What do you mean by a 100 year black hole? Are you referring to Hawking radiation? $\endgroup$

  • $\begingroup$ @MaciejPiechotka I think such a hole could be dicovered already much sooner than a year ahead. $\endgroup$

  • $\begingroup$ A black hole which evaporates in 100 years. Yes. 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). $\endgroup$
