No. A vacuum cleaner works by creating low air pressure inside of itself, which suck in air. That moving air can then carry small objects with it. Things sucked into a vacuum cleaner go to a bag or chamber that is then thrown out or emptied in the trash.
A black hole is an object that has completely collapsed under the force of gravity. Objects near a black hole are not suck in; they fall in due to gravity, just like what makes things fall on Earth, only much stronger. Unlike with a vacuum cleaner, which can be emptied, nothing that enters a black hole can ever leave.
No, the absence of matter would be a vacuum, which is quite different from a black hole. A regular black hole has a fairly large amount of mass (which is basically the same as matter) in a small space.
A photon is classed as a 'massless' particle. However as mass and energy are aspects of the same thing it has mass by virtue its energy content. It is not a simple and easily explained subject. It is necessary to learn some rather difficult mathematics.
Herbert Hoover and Hoover vacuum cleaners. They are not related and neither is J.Edgar Hoover.
No, they are not the same. A singularity would be inside a black hole.
The experts in Boston rate the vacuum cleaner by first testing the product to see if it works. Then after they test the vacuum cleaner, they evaluate on how effective it picks up dirty based on quality. Then they do the same with other vacuum cleaners. After they finished testing them, they score them. The ones with the highest score gets the highest recommendation that's mostly likely to be sold in markets.
If you jumped into an "ordinary" Schwarzschild black hole, you would be crushed into a long line of particles, which means death by a black hole. If you jumped into a Kerr black hole, the same process may occur, but the only thing different is that a Kerr black hole spins, and a Schwarzschild black hole does not. That answer needs a bit more detail. Please use the "related link" below.
The term 'black hole' is particularly appropriate in its application to the astrophysical phenomenon of the same name due to the property of the escape velocity exceeding the speed of light. This means that no light or matter escapes a black hole.
Black holes don't reach out and grab things that happen to be passing by. Outside of the hole's "event horizon" it has the same influence as any other object with the same mass. Other bodies that pass a black hole at a distance at which they're moving slower than escape velocity will settle into orbit around the 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.
Depends!!!A white dwarf created from a star the same size as our Sun will only be the size of our Earth.A supermassive black hole can have a diameter of 150 million kilometers (Same distance from the Earth to the Sun).However a stellar black hole can only be 30 kilometers in diameter.There is no minimum size for a black hole, so one "could" be as small as 0.1mm
Many vacuum cleaner dealers that sell certain brand of vacuum usually can repair the same model and brand that they sell. However, some dealers are not repair experts, so you will have to ask around.
As far as we know, black holes cannot collapse any further. However, if a star were to collapse and form a black hole, its mass would be the same.
