how does motion of an object molving at relativistic speed in Space change its atoms size and mass?

Answer 1

At relativistic velocities, length in the direction of motion is foreshortened. A rocket ship would get shorter and time would dilate, but the humans inside would not be aware. Atoms (orbiting electrons) and nuclei would also be shortened in the direction of motion becoming elliptical rather than round. Because it requires a great deal of energy to accelerate any mass to relativistic speed, and E=mC2 shows the mass equivalent of the energy, the mass of the moving object or atom increases.

Answer 2

Well someone must have figured it out mathematically but I think,,,
As an object travels at the speed of light, the atoms that it is made of would remain the same unless there were outside forces that would alter them, i.e. subatomic particles that would bombard the craft from the outside. Also solar wind (radiation) is known to pass right thru a craft. This could alter the atoms in a craft depending on the amount of exposure and length of exposure.
As far as the mass goes, it would remain the same BUT it would seem weightless for the center of gravity of the craft would be left very far behind at light speed. As you go faster in a car, the center of gravity goes from under your butt to behind the back seat. Go faster and the center would be at your back bumper. Faster still you have now left your center of gravity outside the realm of the car.
Got to go to the bank now...

Answer 3

When an object is moving with relativistic speed implies that the speed is with respect to an observer who is not moving with that speed (the observer assumes he is at rest).

The change of mass, length and time of the one who is moving with relativistic speed is only relative the observer at rest.

The observer is using his own measuring instruments and units to find the change in the other man’s physical quantities.

He observes that the other man is going with relativistic speed and hence his mass, length and time are NOT the same as that of he is using and their physical structure has changed.

Nevertheless, the other man will not notice any change in the physical structure of objects which he carries along with him.

For the man in the space ship, he is at rest, and for him it is the other observer who is moving relative to him and all the objects which are along with the other observer has changed their mass etc.

Being relative to each other, the question of (absolute) change of size and mass does not arise at all.

Answer 4

Well to put it simply...

"The faster you move, the smaller you become"....in relative mass and size.

This is how black holes can fit entire stars and planets into a space the size of texas. The gravity is so intense in a black hole that it even pulls in light, so when an object travels into a black hole it is essentially moving at the speed of light the closer it gets to the core. When any object moves at the speed of light, it becomes atomic (light/energy).

Answer 5

It can only do that if it passes through a solar system close enouph to be affected by gravitational pull, then slightly enter a stratosphere where by it loses mass. If it does not happen - it will never change.

Answer 6

according to someone that does this stuff, as an electron is accellerated to nearly C, it begins to take on a helical path.

my guess is that this path resembles the orbits of the particles in a photon, and is an attempt to fit he electron's constituant photons into time.
