Another disadvantage of recycling which makes it unviable is that for the manufacturers economically, the recycled material is not highly demanded since its quality is not as good as the original material.

A new consciousness is to dawn. Science has not been able to demystify existence. This is now recognized not by ordinary technicians but by geniuses, because they are the pioneers; they can see the dawn very close by, they are the prophets. Albert Einstein said that science has failed in demystifying existence, that on the contrary, it has mystified things even more.
e.g., it was so easy-just 100 years ago-for the scientist to say that all is matter. Now matter has disappeared; in neon-physics there is no entity called matter. The deeper the physicist went into the world of matter, the less matter was found ; it is all pure energy . Can we define energy ? Energy can not be material; it is something totally different from matter . Matter is static, energy is dynamic; matter is a noun, energy is a verb. Matter is measurable. That is exactly, the meaning of the word 'matter'. It comes from 'measure', the root means 'measurable'. Matter can be measured, that's why it is called matter. Energy is immeasurable, it can not be called matter. Hence, physicists get more puzzled the more they probe into the world energy.
Q. What is the contrary thing that science has done?
