I’m wrong! I’m wrong! I know it! Who am I to question the likes of Albert Einstein? But, my itsy bitsy teeny-weenie mind just won’t accept the great man’s idea of Space-Time Fabric. So, as I think this mystery through I’ll describe my many questions in the hope that someone might offer a comment that will explain why I’m wrong (and do it in layman’s terms). If you wish to learn more about Einstein’s Space-Time fabric just click on the link for a two minute video on this subject. https://youtu.be/-m3SddsTSAY
Consistency of the Space-Time Fabric
To make it brief, the sun curves space around it. The planets of our solar system roll along the inside of this curve as they orbit the sun. Here are the problems I have with this theory:
In order for space to ripple, curve, wave, or do anything, it has to have a physical presence in the universe. It has to be made of some kind of material. And in order for space to keep a whole planet in orbit around the sun (to keep it from just flying off to parts unknown) then that fabric of space has to have the solidity of a steel bowl a million miles thick. At the same time, if the space-time fabric were made of steel it would eat away at the planets, grinding away at them until they all look like the dirt ring around a bathtub.
However, if the space-time fabric were as soft as, say, a sponge, then the planets would wear a groove into it. And if the fabric were as thin as cellophane the friction of the speeding planets would burn a hole right through it, like the overheated film inside of an old movie projector.
But, space isn’t even as thick as cellophane. The space-time fabric has the consistency of…?…nothing. And yet it keeps the planets from flying out of the solar system? How?
But, We’re Moving!
If you use Google Images to search for pictures of this space-time fabric you’ll find that every image depicts a stationary grid under the sun and planets.
What is not taken into account is that the Earth is orbiting the sun at 67,000 miles per hour. The sun, and the entire solar system, is zooming around the Milky Way at 500,000 MPH. And the galaxy is careening through space at a million miles per hour.
An idling speed boat will displace the water it is sitting in. This is because the water has a physical presence that can be manipulated, so at full speed that water doesn’t just curve under the boat; it is cut into a tremendous boiling wake behind the boat. If the sun can cause the space-time fabric to curve under and around it, then that fabric also has a physical presence. With the sun going at full speed, that fabric would become a violent cauldron of chaos behind it. At that speed there is no way that the fabric of space could hold the planets in orbit around the sun.
Hey, where’s the curve?
A contradiction here
LIGO, which is the acronym for The Laser Interferometer Gravitational-Wave Observatory, claims it has detected space-traveling gravitational waves on Earth. It shoots a laser that is split into two sections, each leading to a mirror, which in turn reflects the light back. If both reflected lights hit each other at the same time, they cancel each other out. But, if a gravitational wave elongates one of the lights it will be delayed, causing the other light to reach a detector, marking the fact that a gravity wave has just passed through.
My problem with detecting gravity waves on Earth is that, seeing as the Earth creates its own curve in the fabric of space, then a gravity wave would follow that curve and completely miss the planet.
Apparently, all of my suppositions are just plain wrong. It’s frustrating. Annoying! I want to accept Einstein’s idea of the fabric of space. But, at this time I just can’t. :- (
