I came across this, and it is truly mind blowing.
Keep in mind that there are at least thousands of black holes in our galaxy, with a super massive black hole in the center.
There are as many as 4 trillion galaxies in the known universe, each with hundreds of billions of stars.
Super massive black holes are in the center of at least the largest galaxies.

Read the article, then watch the video.

The earth is really an insignificant tiny chunk of dirt, at least on a galactic or universal scale.
It is very significant to us, as we live here.

can one day a super blackhole , billions time bigger than the biggest at this day, explode in a new big bang ?

Possibly. I have guessed that our universe is a black hole explosion.
I vision a black hole as a single particle of infinite density. No protons, electrons, neutrons, quarks, or anything except solid matter.
Its gravity warps space tremendously. I always wondered if it is feasible for a black hole to be so big, it would crush in on itself, immediately
changing every bit of it to energy. The temperature would be what existed in the big bang, requiring a bit of time to cool enough to reform matter
as what we guess happened at the beginning of our universe. Of course, I certainly don't know, but it seems to make sense.

Have black holes really been confirmed to exist? Have astronomers observed things getting sucked into them?

Yes. The gravity waves we detected came from two merging black holes, and two merging neutron stars.
At the center of our galaxy, if you peel the stars back, you can see stars orbiting an invisible object at millions of miles an hour.

A quasar is a black hole feeding on it's galaxy. Huge jets of material and energy shoot out of the poles, generated from the edge of the event horizon. The tidal forces are enormous on the matter entering a black hole.

Radio Jets from the Milky Way’s Black Hole Could be Pointing Right at Earth

Should we worry? Not really.
There is far too much stuff in space between us and the jet, so it slows down pretty quickly before it reaches us.
Another possibility is that the gas disc simply does not have such jet.

Alma telescope in Chili, found this one, maybe more out there.

Astronomers have detected a stealthy black hole from its effects on an interstellar gas cloud. This intermediate-mass black hole is one of over 100 million quiet black holes expected to be lurking in the galaxy. These results provide a new method to search for other hidden black holes and help us understand the growth and evolution of black holes.

So why bother wasting time even thinking about it when there is a lovely Spring day out there to go and enjoy.
ROFLMAO.
