According to the relativity, when you travel around 99.999999...% of the speed of light, you would be a Black Hole. V------------->C mrelative------>infinite Fg------------>infinite Fast moving Black Hole. At the fast moving state, this gravity force relationship, Fg=mrelative g is uncertain. But, the high energy density (energy/volume) can make the object to be a Black Hole.

Does entropy really explain time vector?
alpha2cen replied to Jeremy Mallin's topic in Modern and Theoretical Physics
Locally, the Entropy decreased regions exist, but total Entropy is increased. The problem depends on how to set the system area. -
We know gravitational wave well. Mass makes gravity. And, at the view of relativity theory, the gravity is a spacetime deformation phenomena. And, we have not found the wave yet. Does spacetime vibration make gavitational wave?

Does space-time moving speed make the gravitational wave?
-
Is this the speed of gravity? Vg; the speed of gravity How do we know that the gravitational field becomes equilibrium?
-
Good idea. Similar. Operating system -- A computer hardware connections+ software connections. Networking --- Computers connections + other connections.

High mass Black Hole is always stable? We have never heard of Black Hole explosion. Are there no limitation of mass gathering? What is the maximum mass density (mass per unit volume) in the Universe?

This is the Dark Matter detection experiment. Even condensed matter experiment, i.e., solid experiment, to find out a nucleus is not easy. How about using more condensed state? Metalic hydrogen. Metal hydrogen contains more nucleus per unit volume. Before doing this experiment, observing the Jupiter, Saturn and Sun ' inside would be useful.

Atoms cooled to negative degrees Kelvin for first time.
alpha2cen replied to Moontanman's topic in Science News
This is 0 law of thermodynamics. Does this experiment obey this rule? -
How can the universe be infinite in size?
alpha2cen replied to Airbrush's topic in Astronomy and Cosmology
These are references about " Inflation". http://map.gsfc.nasa.gov/media/060915/index.html http://en.wikipedia.org/wiki/Time_dilation http://en.wikipedia.org/wiki/Inflation_%28cosmology%29 -
Basic programs are loaded in the Rom to do that work. When we turn on the computer, the loaded program do their job according to the assembly language.

How can the universe be infinite in size?
alpha2cen replied to Airbrush's topic in Astronomy and Cosmology
At the viewpoint of relativity theory we explain why it spent very small time during the Inflation. How about this Figure? -

From the calculated reslts the expansion rate is very high near the beginning. The shape of the expansion curve is very steep. This result is calculted from the space expansion model. Data --> simple model --> result Other factors are eliminated. http://blogs.scienceforums.net/alpha2cen/2012/12/24/space-expansion-model-universe-expansion-graph/ -
C) Potential energy is a state function, and work is a path function

Generally, 3 dimensional graph representing f(x,y) or (x, y, z) This case is (t, v(t), m)

This is more exact Figure. The example of [mass. length] dimension is diffcult to make.

The system can be used at the constant lever system ----------------------------------------------------------- ^ 000 const mass L M In the SI unit system, L's unit is m, M's unit is kg, and k's unit is kg.m. It is difficult to find out a general physical system to use such unit.
-
kg.m is [Mass][Length]. It is not 'Mass x Position' . The unit will be useful when we calculate an iron wire length. L=k/M. Where L is length, M is mass and k is constant. When we know k value, we can easily calculate the wire length from it's mass. It is not a commonly used unit for the physical problem calculation.

What will extraterrestrial intelligence look like?
alpha2cen replied to Moontanman's topic in Speculations
If they were able to use superluminal technology and quantum telepotation, we might meet them in the future. Does it have any meaning talking about the appearance of such creature which has very advanced technology? They could ealily change their appearance without any difficulty. -
Two forces are always the same. The difference is that dF/dt is 0 or other t function. If dF/dt is zero, It might be a constant acceleration moving or not moving condition. If dF/dt is not zero, it might be a nonconstant acceleration. This is a general case when we move something.
-
In this case, the force acting point is important. I draw a detail picture about the problem.

The method of solving square root is important at the high precision computation. Good compiler gives more accurate answer at the long digit computation. http://www.codeproject.com/Articles/69941/Best-Square-Root-Method-Algorithm-Function-Precisi

How to explaining the annihilation phenomena correctly? Which one is more correct between the below two models?

This is an example of a good compiler. Hardware, operating system, good compiler and good conecton to the http program make high precision computing results. http://en.wikipedia.org/wiki/Extended_precision
