Isnt true that in the proper frame of reference the mass remains the same. From an observer the mass may not appear the same it may even appear schrunk in dimension.?

Rain show a mass increase as soaked water in the moving body.sasuming an infinite rain and distance the body move it gets wet as a function of time no
matteter how fast(speed of light or not)the
motion.A rain relativity experiment would this be correct?

Thermodynamics law imply you cannot obtain increase in mass out of no where just because a system is moving.
There has to be a mass flux getting absorbed into the mass. from exterior source.Is that true?

Mass does indeed increase with velocity, but that can't be proved at the low speeds that we experience from day to day.

Rain simply has nothing to do with Mass increasing. But if you RUN when it's raining, you will be getting dry sooner. If you just stand there like an IDIOT, you simply get wetter for being in the rain longer.

It's logic, not quantum physics.

If you run in the rain, you MIGHT absorb more rain water per second than when you're walking, but you'll also spend less time absorbing rain water.

That has nothing to do with your mass increasing or decreasing. It has to do with increasing the amount of surface area that is exposed to the rain. If the rain were falling straight down and you were standing still, only your head and shoulders would be taking rain drops directly (even though they would roll down the rest of your body). If you're running, you have to compare your speed to the speed that the rain drops are falling and calculate the angle that the rain drops are hitting you. The cross sectional area exposed to the rain determines the rate that the rain is hitting you.

That also means that if a wind were blowing from directly behind you making the rain come down at an angle, running would actually reduce your cross sectional area relative to the rain. Running at the same speed as the wind would expose you to the least amount of rain per second. Running slower than the wind or running faster than the wind would increase the rate you were getting wet.

According to the equation of mass variation given by Einsteins in his theory of special relativity

m = mo
___________
sq 1- v^2 /c^2

m= mass of a body moving with some velocity
mo=rest mass of the body
v =is the velocity of the body
c= speed of light

So from the above equation if v=c the m becomes infinity
so it is not possible to observe the variation in mass for small velocities so if you could run in the speed of light then you can feel that all the rain that fall's will fall on you. just because you would acquire infinite mass

You might ask what infinite mass means and it actually signifies that you can escape to higher dimension's according to string theory. it is believed that the universe has infinite mass and it is believed to traveling at the speed of light. so if you can run in the speed of light then you can become in phase with the universe

According to the Theory of Relativity, absurd things happen when you travel as a speed comparable to the speed of light. Firstly, time slows down. Next, your length contracts, that is you become thinner. Besides, your mass increase. For example, take a photon. A photon is not matter, but simple packets of energy know as quanta. But all photons travel at the speed of light. According to de Broglie, the wavelength is given by Planck's constant divided by its momentum. This shows that photons have mass when it is travelling at the speed of light. It can be easily proven using E=mc²=hf=hc/lambda. Rearranging, lambda=h/mc=h/p, where p is the momentum of the photon.

That is untrue because when you run you increase the amount of rain hitting you and therefore you absorb more rain. Proof.

There will be a point of saturation of your clothes and body after running or standing when it is all runoff water LOL. Then you won't be absorbing rain anymore.
