Just like runing in the rain the more it rains the more water our cothes absorb?Other wise the 2nd law of thermodynamics is brocken=which say we cannot obtain anything for nothing.?

OMG noooooooooo.
This question is fundamentally flawed by assuming that mass increases with speed.
This is not true!
The reason for the common misconception is the formula for relativistic momentum:
p = mv / sqrt(1-(v^2/c^2))
where mv is the classsical momentum.
Many people wiew the 1/sqrt(1-(v^2/c^2)) as a correction factor to the mass which makes it increase with speed. This is totally wrong! The 1/sqrt(1-(v^2/c^2)) is a correction factor for the velocitity.

Also note that E = mc^2 DOES NOT mean that an object can freely convert energy into mass or mass into energy at will.
The energy described by E=mc^2 can only be released if mass somehow disappears, like in a nuclear reaction, where the mass of the reactant nuclei is greater than the mass of the product nuclei.

The second law of thermodynamics is not broken. It is an experimentally verified physical law (to all scales of measurement that we have currently been able to verify it).

Now, this means that your question is now obsolete - but to say it a different way, no micro-masses are being absorbed.
The idea of micro-masses/charges existing everywhere in the universe, IS acceptable from a quantum mechanical stand point. In this model, free vacuum energy is used to produce particle-antiparticle pairs. These particles don't really interact with much though (unless there's a black hole nearby, where they are thought to produce Hawking Radiation.)

The notion of absorption of micro-masses is wrong. Nor are we getting something for nothing. Suppose that you are applying an acceleration to a body, such that its increasing speed results in an increase of mass. The mass increase comes from the energy absorbed by the body due to the accelerating force on it. At high speeds, most of the acceleration energy shows up as increased mass rather than increased speed.

Particles have to pick up quite a lot of speed to start increasing in mass.

But when they do start increasing in mass, it is because they have turned energy into mass, as is allowed in the E=mc^2 equation.

Since energy and mass are just two different manifestations of the same thing, this transformation can happen, and does not violate and laws.

Mass doesn't increase as speed increases. This assumption violates basic laws of physics. This is a false interpretation of the theory of relativity
