The Fabric of Space Time

This morning I read the Quantum Day article “Binary White Dwarf System J0651 Emits Gravitational Waves”. It says just as sound waves require a medium such as air to travel through, gravitational waves as predicted by Einstein though as yet undetected would require a medium of travel as well.

That medium would be the so-called fabric of space time.

Quirky Ideas

Though I am not certain such a fabric exists, I feel it is one of the more believable concepts in modern physics. I decided to speculate on the nature of that fabric. Is it absolutely continuous and smooth? Or might it only appear such, as air and water appear smooth, when they are actually made of discrete particles?

Fabric of Space Time – A Flashback

If the fabric of space time consists of discrete particles, then it is not such a new concept at all. How is that? If that is the case, it is reminiscent of the scientific concept of the aether (ether). Many famous historical scientists accepted the concept of an ether, including the founder of the wave theory of light, Christian Huygens. Believing similarly was the most famous gravitational scientist, Sir Isaac Newton.

If the aether proves to be equivalent to the fabric of space time, then the old saying is really true, “what goes around comes around.”
