I’m always talking in retrograde fashion . . . but the first LIGO results were of two black holes merging. A large percentage of the mass was radiated away in the form of gravity waves, but the end result was bigger than either of the two starting black holes. So if you have a multiple star system with really big stars, it seems to me they could conceivably all end up as black holes, then merge one by one. And in a globular star cluster, where the stars are packed closely together, black holes from different star systems could conceivably merge.
But maybe they’re talking about black holes that are the end result of just one star.
I agree it may be possible, but I still wonder if there might be an issue of the amount of mass that would need to accumulate and the range it would need to accumulate within, without ending up being dispersed by the tug-of-war that would be going on in that hypothetical neighborhood or by other events.
And (but? then again? darn grammar), on the other hand, the data seems to suggest this happens way more frequently than previously expected…
In a centralized system, all biomass in a region is brought to a central plant (i.e. biomass-fueled thermal power station[21]) for processing into biochar.
Biochar is a form of charcoal produced when organic matter – for example wood, leaves or dead plants – is heated at high temperatures with little or no oxygen in a process called pyrolysis.
I thought so too. But apparently if the microstructure of the plants can be retained (tubules and such) it can promote biological infiltration thus being a precursor to soil.
I have no idea if that’s unique to “biochar” or if charcoal has it too.
