Is there any truth that some scientists, if any at all, think our universe itself was the result of the collapse of material prior, leading to a singularity that lead to the big bang? 
Sounds like you mean the Big Bounce. Apparently it's a viable possibility.

At the age of five, Skagra decided emphatically that God did not exist. This revelation tends to make most people in the universe who have it react in one of two ways - with relief or with despair. Only Skagra responded to it by thinking, 'Wait a second. That means there's a situation vacant.'

I am going to admit what I am about to say, I have pondered but it is pure speculation on my part. If I am not correct, and please correct me, science has yet to say something vs nothing, but from what I get from Lawrence Krauss is that coming out of nothing is possible. Am I correct about that so far? Secondly. after all I have read over the years about something vs nothing, finite vs infinite, my take on it is that they are not mutually exclusive. I am seeing the universe as almost the same as the atmosphere of our planet, a season starts, then it ends, another starts then ends, ect then the cycle repeats. So mentally I am thinking "all this" can be forever and does avoid the bullshit problem of a super hero cognition factory boss which causes the problem with infinite regress, but more like an oscillation from off to on, energy gets spent to decay to off, the decay collapses to a dense spot, BOOM another big bang. Like a light switch is off for a while, gets turned on for a while, light bulb burns out, collapses to off, till a qm twitch and booms back to on again? Am I even close here? My point is that cycle can be forever and the finite parts are off and on fluctuation between? I changed my mind Mr Brewer, I now believe in reincarnation, you were in a prior life one of the morons on Easter Island who said when others were saying to you "Dude, we are over populated", you "Who gives a fuck". Idiot. Take care of yourself Han, I guess that is what you are best at. 
The Universe is too light for a Big Crunch but what came "before" (as flawed as that term is when discussing the origin of space-time) is another question entirely.
Krauss certainly argues in favour of a Quantum Fluctuation origin, though it may well be the case that we'll never know, to paraphrase the late Sir Patrick Moore.

That would be a Type I supernova. The second star, typically a white dwarf, has its material stripped away by its companion, which adds to that star's mass and pushes it over the Chandrasekar Limit (1.4 times our Sun's mass). It takes a star at least that mass to produce a supernova by itself, a Type II. Our own Sol is neither. We do end up losing the Earth to it eventually, however, so unless you panic-buy SPF HolyMotherFuckingShit, you might want to consider looking further afield for a desirable location with easy access to shopping and leisure facilities.

@Stimbo
Novas (sans super) also arise similar to Type Ia Supernovae, but on a white dwarf rather than a neutron star.

That's true, of course.

The god who allows children to be raped out of respect for the free will choice of the rapist, but punishes gay men for engaging in mutually consensual sex couldn't possibly be responsible for an intelligently designed universe.
