Looking for a flat retractible or reel hose made from hard plastic? Saw a fellow contractor have one not the best pressure but was quick and easy to store in between jobs, I need something that will hold up
A black hole is perhaps better called a frozen star. A star exists because the the outward force of the thermonuclear fusion of its core balances the inward force of its gravity. When the hydrogen core is converted to helium through fusion, the helium then fuses. Once the fusion process has exhausted all fuel, gravity overwhelms the outward force, and the star collapses. if the star has sufficient mass, it will collapse without limit, that is, it will collapse to an infinitely small point. Because the large mass has infinitely small volume, it has infinite density and infinite gravitation within a certain distance. The infinite gravity traps light which has mass-energy. Light is bent by mass and in the vicinity of a black hole it can be infinitely bent, and trapped within the black hole event horizon.
If a black hole could exist it would be a 2 solar mass sphere about 3 km in diameters with a surface gravity such that the surface escape velocity would be greater than the speed of light. Since nothing could escape the surface it would be invisible. It would act like any other celestial body of 2 solar masses and could actually have a bevy of planets orbiting it.
A front sand tire has ridges that help you track in the loose sand. To be honest I have never seen much of a difference with my front tire. Now the rear tire yes.
Nobody really knows for sure what is going on there
