They say much about the Einstein's theory now. According to Einstein the ether does not exist and many people agree with him. But it is a mistake in my opinion. Ether's opponents refer to the experiments of Maykelson - Morli [Michelson-Morley] who made attempts to detect the Earth's movement relative to the fixed-bed ether. These experiments failed, however it didn't mean the ether's non-existence. I always based as fact the existence of mechanical ether in my works and therefore I could achieve positive success.
