You can create a slurry of any less dense material with water and make it homogeneous (like milk and butterfat). Mud is a mixture of dirt and water with a density of more than 1.0.
When matter turns into energy it gives off a great deal of heat! Think A-bomb. If a neutron star collapsed to a point by convert into energy the heat released would blow it apart. So I do not think this works.
A neutron star can grow by accumulating more stars and become more massive enough to increase the gravity at the event horizon, thus becoming a black hole. This does not require it to become infinitely small. This, of course, is just my opinion. I cannot accept the idea of a singularity...
I tend to agree with Bill, the idea of a singularity just does not make sense. Why cannot a neutron star be massive enough or small enough to create a black hole. The smallest particle must be incompressible beyond some level of pressure.
Of course time has existed since motion of things started. The OP suggested a scenario where nothing exists, empty space, no matter. In this case there will be no motion, therefore nothing to measure time with. Therefore no time.
I believe time is a creation of man. Not a basic physical law of nature as is gravity, for instance. First time was used to measure the rotation of Earth and defined the duration of its motion as a DAY. Then the lunar calendar used the motion of the moon rotating around the Earth as a MONTH...
Time in life cycle is very important also. Intelligent life, as defined by WeW, has only been around on Earth for 100 years or less out of the 5 billion years of Earth's existence. Who knows how long it will continue to be on Earth. If each of the billions of stars in our galaxy had one planet...
Is it not a combination of mass and distance from the center to the surface (radius) that create a black hole? If we use the Newtonian equation of acceleration due to gravity and set the escape velocity equal to the speed of light, we could calculate a mass/radius relationship that would be...
There is a huge hole in the turbine building directly seaward from unit #3. Is this a possible location that the heavy item rejected in the explosion of #3, and could it lead to finding higher rad levels in the turbine buildings?
Can't we design these plants be to be "fail-safe"? That is in any major interruption in outside power or people can the plants control their own shut-down and cooling maintenance using only gravity or waste heat/steam from the decay of spent fuel. Assume all people and services external to the...
We must see the CMB as a point in space-time that was produced 13.7 BLY ago, near the "big bang" time. Those objects that we see near the 13.7 BLY range must be much farther away now since space has been expanding ever since they emitted the light we see now.
We and everyone else in the...
