How to super massive black hole form?

You do realize that the early Universe has less metals, right? This in turn aided the creation of more massive stars during that time. Another thing, the early Universe is a lot more crowded than it is today. Any molecular cloud can collapse easily into giant stars. Another thing, the availability of collapsing material may even lead not to a star but directly to black holes given the right conditions and the excess mass. Some of the Population III stars may even exceed 500 solar masses. Anyone of them will live very short lives, probably less than a million years leading to more shocks that compress their parent clouds.

Coalescing into intermediate black holes and then finally into SMBHs, they may have led to the foundation of most galaxies we see today. Have you read how some globular clusters form? See NGC3603, the Arches cluster and the Quintiplet. If some of these massive and compact open clusters' core stars collapse into black holes and then coalesce into IMBHs and then finally be slingshot out as compact globular clusters, then we are seeing a miniature version of how our ancestral galaxies formed way back.

You should answer some of my questions! I don't ask them anymore since I get either very few (even none) or unsatisfying answers. See some below ( I just chose randomly):

Clear skies!

Addendum: Say, we have at least a few cores each containing a mere thousand solar masses. From there, we can create a fairly large IMBH over a hundred thousand solar masses. Given the observation that most quasars are distant, wouldn't that help the theory that after a certain point, SMBHs got their bulk from accreting matter over their entire lifetime with a peak in the early days of the Universe? Not all SMBH are large, the puny 4.1 million solar masses Sagittarius A* demonstrates that the Milky Way being a large spiral has not met as many big mergers as much as galaxies like M87 which is an elliptical. M31's 125 million solar mass SMBH is a product of a clear merger since its own stellar count and expanded size (from relaxation and gain of angular momentum) plus the runaway galaxies im the Maffei Group all prove this speculation. I have more to write but I am lazy and I am thinking the space here isn't enough. Also in the end you have to say "In fact the really answer should be we just don't know yet." Cool! I will post a question and be sure to answer that one as much as I answered this one, at least.

I just watched the Stephen Hawking doc on this last night. When a massive star begins to burn out it creates carbon and iron around it's core therefor not as much energy escapes. The atoms within the hardened layers condense extremely until it finally fuses and collapses blasting all outer areas of star into a supernova whilst the inner areas become so so dense that it's gravity traps all the core and even light can't escape due to gravity. 400 million times the mass of the sun is the largest one spread over just 12 thousand killometres diameter. They predict that eventually black holes will eat the universe.

collapse directly to a black hole without becoming a star on the way.

Or starts as a stellar mass black hole formed in supernova as usual, which grows by accretion. Gas to start with then whole stars fall into it as is happening with the one in our galaxy - this will increase the size of the black hole over time no matter how it was formed.

Or core collapse of star cluster - tendency of heavier stars to settle in the centre and lose their momentum to the lighter stars - could lead to the heaviest stars merging to form a black hole

Or primordial, formed soon after the big bang

It a black hole could exist it it would from after the collapse caused be the explosion of a massive star,the black hole would have a mass of about 2 solar masses it would expand by consuming galaxies.

There are several theories about how they form. Probably the best I can do is point you to the Wikipedia article, which is honestly not some lame music video...

This video is good, and should answer all your questions;
