Like that title? A racer who believes in racing could be called a racist, right? Like artist, pianist or balloonist? Anyway…
This is about racing through space, although it’s not actually a competition I’m talking about but the increasing speed of galaxies the further away from ours they are. Our astronomers are convinced that the Universe is expanding faster and faster as it’s general expansion increases, and I have a very simple explanation for that, that doesn’t involve antimatter, Dark Matter or energy-filled space.
It only involves centrifugal force.
“They” also tell us that the Universe is wheel-shaped the same way almost all galaxies are. Everything spinning around a central core, only in the case of the Universe it’s galaxies doing the spinning instead of stars whirling around a galactic core. Okay, this sounds reasonable.
So, go to a playground where there’s one of those mini-merry go rounds, whatever they’re called, the steel round things on a center pivot and segmented like an orange sliced in half, with steel bars to hang onto. Go to the center of it and have someone turn it and see how much pull there is on you toward the outside. Almost none. Keep the rate of turn constant and start moving toward the outside of the thing and as you do, you’ll feel the pull to the outside grow stronger. That’s because the distance you travel with each revolution while at the center is almost none, so your ground speed is almost zero. But as you move toward the rim, the distance you travel with each revolution increases, meaning you’re going faster over the ground and the pull toward the rim increases. Another way is to imagine you have a rock tied to a string and you’re spinning it around over your head. If the string is only a foot long, you don’t feel much pull from the rock, but if the string is 5 or 6 feet long, that same rock at the same rate of spin starts feeling pretty heavy.
Centrifugal force is centrifugal force, it doesn’t matter if it’s on playground equipment or a spinning Universe, the closer a galaxy gets to the rim, the stronger the pull away from the center and since galaxies don’t have steel bars to hang onto, they’re continually accelerating, faster and faster as they move further and further from the Universe’s center.
Why is this so difficult? Astronomers have been searching for “Dark Matter” to explain this expansion for decades and no Cern Colliders and other massive efforts are going to discover it, because it isn’t there. That’s why this theory of matter is called Dark. No one’s ever been able to find it. Pretty dark if it can’t be seen.
And, an observation. The shape of the Universe is more like a round ball slightly flattened on each side and tapering to a thin wedge at the edges, than it is like a wheel. Like a Frisbee that’s fat in the middle, if that helps. This is because, if the Big Bang actually happened, the Universe expanded in all directions and at first was shaped like a ball. But it’s a spinning ball and most stuff that spins off a ball does it from the center line of it, like a yoyo, because once again that’s where centrifugal force is strongest.
