Black holes are basically large amounts of mass in a small space - when matter is concentrated to such an extent that the gravitational force becomes so strong that a ray of light can't escape this space.

What is the mass of the biggest black hole?

That depends. The smallest black holes known are generated by the collapse of massive stars, so the holes themselves tend to be rather massive--on the order of the mass of a star. Most galaxies contain black holes that mass hundreds of thousands to billions of times that of our sun. Sagittarius A, our Milky Way's black hole, is a little over four million solar masses. It is possible quantum black holes formed during the big bang. These would have been tiny singularities, with masses measured on the atomic scale. Stephen Hawking demonstrated fairly effectively such black holes would have preferentially absorbed charged particles from the quantum foam, bleeding mass until they evaporated. It is unlikely any would now be left from 13.7 billion years ago.


What is the best method for using foam to fill holes in a wall?

The best method for using foam to fill holes in a wall is to first clean the area around the hole, then insert the foam nozzle into the hole and slowly fill it with foam. Allow the foam to expand and dry completely before trimming off any excess foam and sanding it smooth for a finished look.

I have a concrete tile roof. There is a black foam that fills the open spaces between the house and tiles. The home is about seven years old and all this foam is falling out of its spaces allowing holes for rain and animals. What is this foam called?

How can foam be used to cover holes effectively?

Foam can be used to cover holes effectively by expanding to fill the space and creating a seal that blocks air and moisture from entering. This can help to insulate and protect the area, preventing leaks and drafts.

How can I effectively use spray foam to fill holes in my walls?

To effectively use spray foam to fill holes in your walls, follow these steps: Clean the area around the hole to remove any debris or dust. Shake the spray foam canister well before use. Insert the nozzle into the hole and spray the foam slowly to fill the space. Allow the foam to expand and cure according to the manufacturer's instructions. Trim off any excess foam once it has dried completely. Sand and paint over the filled area for a seamless finish.

What foam is?

The most general definition of foam is a substance that is formed by trapping many gas bubbles in a liquid or solid. It can also refer to anything that is analogous to such a phenomenon, such as quantum foam. Often the term is used in reference to polyurethane foam (foam rubber), XPS foam, Styrofoam or some other manufactured foam. It can be considered a type of colloid.(Copy from Wikipedia:Foam)To create a foam, you need to start with a liquid viscous enough to hold some shape. Water alone will not do this. Try taking room-temperature egg whites and whisk them in a large bowl. Do this vigorously until you produce... (ta daa!) foam.


Is the Quantum Foam the actual cosmic dark matter?

It is not currently know what exactly dark matter is made of. However, it is suspected to be some sort of particle.


Is the hockey o stick hollow?

the reebok o stick is semi hollow so to say. from about a inch above the "o's" or holes inthe stick there is black foam in the shaft and blade for support and strength. from there up the stick is hollow for the rest of the shaft. the reason behind the holes in the shaft of the stick is for weight savings and strength. if you look closely at the holes they are not perfectly round they are oval and that is for strength as an arch displase stress better.
