I think you may be referring to the start up of the Large Hadron Collider at CERN on the Swiss/French border. CERN stands for something like Centre des etudes de recherche nucleaire. This is the world's largest particle accelerator both physically and in terms of energy avilable. There has been some suggestion that when this experiment goes live it may produce very small black holes.
there is secondary evidence of a black hole. there is only secondary, because a black hole can be detected by its surrounding, such as the radiation an object gives off as it is being sucked in.
The "swirly" part of the black hole you are referring to is called the accretion disk which consists of the matter being attracted to the black hole.
You can't, if you call it in the black hole being inside the event horizon; that is if you mean inside the 'black' portion of the hole. If you say near the black hole, then it depends on how close and how much thrust, fuel and mass your ship has.
Black holes are generally categorized into three buckets - the largest being called supermassive, the 'medium' being associated with stellar evolution and called 'stellar mass' black holes, and the smallest or tiny ones called "microscopic" black holes.
Yes. Matter falls into black holes all the time; the first known black hole was the "Cygnus X1" black hole, which was discovered by the X-ray emissions caused by matter being pulled off the companion star and falling into the black hole.
It depends, Black holes can go from being microscopic to supermassive black holes that entire galaxies revolve around. It all depends on which black hole and which quasar.
If you can send another object into a black hole you can put garbage through a black hole. But bear in mind, we have no conveniently located black holes, so shipping costs are going to be very high.
The photon sphere of a black hole is a region where light can orbit the black hole before being pulled in, while the event horizon is the point of no return where nothing, not even light, can escape the black hole's gravitational pull. The photon sphere is closer to the black hole than the event horizon.
Gamma radiation emitted by black holes can originate from the accretion disk around the black hole or from high-energy processes within the black hole itself. This radiation can escape the gravitational pull of the black hole and travel through space, potentially affecting nearby objects or being detected by telescopes as a signature of black hole activity.
Yes, a quasar is a galaxy with a super-massive black hole in its center. The hole being invisible, all light vanishing from the great gravity. The quasar itself, among the brightest, most luminous objects in the universe, is being powered by an accretion disc around the black hole.
A black hole's gravitational pull is extremely strong, causing nearby objects and light to be pulled towards it with great force. This can result in objects being stretched and torn apart, and light being bent or absorbed by the black hole.
It depends on where the black hole appeared, but irrespective of that bit of minutia, the same things would happen on the Earth as on the Moon if a black hole appeared somewhere, that being nothing with regards to a specific person.
