In space, if two pieces of the same metal come in contact with each other they will permanently fuse.
Yes, In space if two pieces of the same metal came in contact with each other they will permanently fuse.
This process is called cold welding, caused by atomic diffusion.
But on the condition that the two surfaces of similar metal should be perfectly smooth and corrosion-free and must be pressed together with some force.
However, On earth, we have an atmosphere that is rich in oxygen, due to which a very small protective layer (corrosion ) is formed on different pieces of the same metal surfaces naturally ( oxidation ) so they don’t stick together.
But, in space there is no such atmosphere or oxygen, thus the metal in space doesn't come to know that they are different pieces and get Fused.
Due to the absence of the protective layer, The metal molecules don’t come to know that where is the end and where is starting of the metal. Due to which the electrons and atom molecules start flowing in between the different pieces of metal resulting in infusing and only one single piece of metal.

There is a small story behind this. The great lord buddha who started the very oldest and very famous religion, "BUDDHISM '', was once meditating under a tree. It was a sunny day, and Buddha was deeply engrossed in his meditation. But as time passed, the temperature also increased, and soon the sun lined up on buddha's head.

And it is believed that the time buddha was meditating under the tree, he was bald. A snail passing from there saw Buddha and he noticed that the rays of the sun were falling dir...
