That’s what we have already recorded.&lt;p&gt;This predicted one is not even in the same ballpark. Those 1-6 sun matter into energy conversions are ants compared to what’s coming.&lt;p&gt;These supermassive black holes are thousands to tens of thousands of times the mass of our sun. (Not sure if the ones in this paper are in the billion solar masses class. Yes they do exist)&lt;p&gt;This event will convert the mass of perhaps a hundred or a thousand suns worth of matter into energy in an instant. (Not sure if the paper gives any accurate predictions I’m lazy!)</text></comment>

So for them to say &amp;quot;within 3 years&amp;quot; that&amp;#x27;s like go get the popcorn, you don&amp;#x27;t want to miss it level warning!</text></comment>
