How does our Galaxy maintain a fixed form?
alpha2cen replied to alpha2cen's topic in Astronomy and Cosmology
The ratio of thickness var diameter is about 1/100. So we think that the Galaxy has thin thickness. -
Why does the light travel at precisely the speed...
alpha2cen replied to mreddie1611's topic in Relativity
I mean this kind of measured data. 299700000 299800000 299100000 299600000 This data mean significant figure 4 digit number is varied. How about really measured light speed data? -
This site states you vacuum and anti-matter concept. http://en.wikipedia.org/wiki/Dirac_sea The concept comes from Dirac's theory.

alpha2cen replied to mreddie1611's topic in Relativity
At the light speed measuring experiment, which digit we can find the number vary? I think the measured values have a mean value and a stand deviation. Is really the standard deviation zero? Is the standard deviation is only measuring error? -
The Universe energy is removed at the cooling step. The theory inflation state is an expanded high energy state. It does not mean, I know, expansion cooling.
-
But this concept is useful to describe this phenomena easily. Dirac states us vacuum is the state of full of energy. So, matter is the some of the energy, and anti-matter is energy empty space.

Anti-hydrogen primal mass is opposite, but inertia mass is plus. According to higgs boson concept, inertia mass value is not depend on mass polarity. Inertia mass is like this. If you attach spheres top and down of the rubber plate, and draw the rubber plate, the total fore to draw the plate is depend on the sphere number, not on the position of spheres. In this case the sphere which are attached on the top of the plate is matter and the sphere which are attached below the rubber plate are anti-matter.

Inflation and cooling, then, where is the energies go in the cooling step? i.e. Inflation----- no energy remove-----> Inflation Inflation----- energy remove---------> particle generation Then, how to remove the energy homogeneously?

How do we know light is electromagnetic wave?
alpha2cen replied to alpha2cen's topic in Modern and Theoretical Physics
This is an example. We fill water in the water tank, and shake it, at this time we can hear some sounds. Next, we shout with large voice into the tank, at this time we find some waves are created on the surface of the water in the tank. So we conclude that sound is made of water. Is this any problem? -
We can not see Dark Matter now. And we can not see Dark Energy, either. If there were an life organism which is composed of Dark Matter, the organism would think us blind matter organism. The blind organism might think nothing exist at the beginning of the Universe. But the DM organism may think there exists nothing from nothing. Whose thought is right? The answer is decided after we find DM matter.

Has the light speed no distribution? Are all the photon speed same? -
In the room temperature thermal energy exits as vibration or long length electromagnetic(EM) waves or molecular kinetic energy, etc.. At the high temperature I suppose EM wave energy ratio may be high. Then the highest temperature thermal energy is like this. High UV -----> X ray--------> Gamma ray---->? And the remained energy is stored as quark-gluon plasma state. How shortest wave length EM wave is possible in the real physical world? And the next step? Is the highest cosmic-ray EM wave? For example 1x1020eV.

the origin of the very high energy cosmic ray ?
alpha2cen replied to alpha2cen's topic in Astronomy and Cosmology
Recently observed object in the space through the telescope is the exploded nebula, and the intensity is about peta eV. -
The air resistance is horizontal direction resistance and very small gravity direction resistance. We can not reduce gravity direction acceleration. So, before we obtain gravity direction speed, we have to land down on the ground.
-
The thought is that we can reduce the gravity acceleration . Before we obtain the high gravity velocity, we land down on the ground. Because of this, the plane climb angle is very important. The angle can reduce linear direction velocity. And the soldier's motion is also important, too, as possible as he can, he try to wide his body to increase drag fraction by the wind. And remaining kinetic energy can be reduced by thick snow cushion. This possibility is based on the phenomena during the Hurricane human body is flied by the strong wind. I think this is dangerous and very high skill training.

Sound is can be a dimension, too. New concept.

the origin of the very high energy cosmic ray ?
alpha2cen replied to alpha2cen's topic in Astronomy and Cosmology
The problem is not total energy amount, I assuming, but energy intensity problem. Which reaction makes the high intensity ray? -
Autoclaving questions
alpha2cen replied to Ninja2188's topic in Evolution, Morphology and Exobiology
I think it is better you do it with experienced friend. The operation is related to safety problem. If you have no experience about that apparatus operation, please do the operation with other experienced member. -
Polymerase is an important enzyme. There are many kind of polymerases. They are related to the evolution. How fast and how exactly without error is an important factor at DNA duplication.
-
I mean steady state velocity. And the speed is 1/5 of the light speed.

EM waves can travel through space!
alpha2cen replied to Zarnaxus's topic in Modern and Theoretical Physics
Light can be created without electric or magnetic field. All objects emit waves, whose wave length is depend on temperature. From high temperature to low temperature the wave energy is moved. -
Many fast moving objects exist in the space. If there is very fast moving big object, like planet, and not rotate, are the object's front side gravity and rear side one same? We assume speed of the object is 1/5 of the light speed.
-
One possibility is like this. It is the plane path. First plane lowers the hight as possible as it can be. And suddenly makes it's hight high. At this moment the soldiers jump off the plane. The plane clime angle is very important. Then, soldiers body reduce gravity effect and horizontal direction velocity is reduced by air fraction loss. This is an assumption, but it is not easy.

In L(t) graph tangent line is a velocity v(t). v(ti)=dL/dt|t=ti And In v(t) graph tangent line is an acceleration a(t). a(ti)=dv/dt|t=ti Where a; acceleration L; length v; velocity t; time

The Dark Matter halo concept comes from the phenomena that the velocity distribution of the star movement according to radial direction in the Galaxy is different from the computed results based on Newtonian fluid assuming. But I have not seen any literature about the result that Dark Matter halo simulation is well fitted with the observed data. Are there any good literature about this simulation? In order to do this simulation, we have to assume the Dark Matter property value.
