Why do black holes exist in space, was it from the big bang explosion?

I've heard if there was a way to get to a black hole, it's a short cut so long distance travel would be cut down to be shorter distance. I know that's unrealistic and it's just a fantasy.

    No, the vast majority of them that we know of right now, at least the small ones, were created in supernova explosions of a massive star, at least 25 solar masses or more. Those are the stellar mass ones.

    The supermassive ones at the centers of galaxies are the ones that are a bit mysterious in their origins. Having multiple stellar mass black holes merging at the center of the galaxy simultaneously would not work. So they needed to come from some unknown cause. One theory is that these supermassive ones were created at the Big Bang, already as large as they are now.

      Just intuitively it doesn’t seem surprising that black holes could form circa the Big Bang considering the enormous energy densities at the time.

    No, black holes do NOT exist because of the Big Bang. The Bing Bang was a WHITE hole that created this Universe. The Big Bang was NOT an explosion. The Big Bang was ALL ENERGY. There was NO MATTER exploding in the Big Bang.

    Solar Mass black holes are created by high mass stars, with a minimum of 8 to 10 solar masses, going supernova when they try to fuse iron in their cores. The outer conductive and convective layers explode outward, but the force of pressure from that explosion caused the core of the star to IMPLODE. The core collapse slows down from degeneracy pressure. But if the mass of THE CORE is high enough, it keeps collapsing and imploding to become a BLACK hole with an event horizon, a NEGATIVE mathematical singularity. The Big Bang was a POSITIVE mathematical singularity, a WHITE hole.

    science fact based fiction they are artificial constructs.

    Theoretically, if one could survive crossing the Event Horizon of a Black Hole, one could emerge through a White Hole somewhere else in the Universe. However, this all still Theoretical as no White Hole has ever been discovered.

      Technically, some wormholes don’t need ANY black holes. The Morris-Thorne wormhole metric is such a case. It is not a wormhole that can occur naturally but it’s questionable whether any wormhole can form naturally. Remember, a wormhole is just a metric.
