The flash of light you saw in the sky was not a UFO. Swamp gas from a weather balloon was trapped in a thermal pocket and reflected the light from Venus.

### Re: The speed of an object on the equator of the earth

The mental trick to be able to think the motion of a point on the equator, is that somehow we think the earth is not moving, which if we are using any motion as movement, can’t be true. As we know, the earth is moving around the sun, the sun is moving around the galaxy, and even the galaxy is considered moving in relation to the rest of the Universe.

So, and this seems self evident, if we claim the circular motion of the earth counts as movement, then so does everything else, and the speed of a point in the equator is nothing at all like 1000 mph

It’s not even in the ballpark, the speed of a point in the equator isn’t even close to 1000 mph, much less “ heading East”, which is the claim NASA and others make.

The mental trick is to only consider one very small factor in calculating the speed, which is OK if you are saying “ relative to ....”

Relative to what? That is the question. In relation to what POV are you claiming this motion? What location are you measuring from?

If you are going to ignore every other motion to make the claim, you still have to define where you are measuring the speed from. Which nobody here has, and nobody anywhere has. And since there actually isn’t anywhere you can measure or observe this speed, it just isn’t how it is

Certainly there is motion, that’s not the problem.

Here's the first one.

movement is relative, except when it is absolute.

### Re: The speed of an object on the equator of the earth

If you are going to count the rotation of the earth as speed, then the speed of the earth around the sun also counts as speed. So when the point on the equator is going with the earth's speed around the sun, the point is moving at 68.000 mph, then reduces to 67,000 mph when it is 6 hours later, reduces to 66,000 6 hours later, when it is opposite the motion, then 67,000 mph again, then 6 hours later 68,000 mph.

This claim is just as valid as the 1000 mph claim.

67,000 mph = earth's average speed around the sun

This "going east" thing is an entirely different matter.

That was not moving

### Re: The speed of an object on the equator of the earth

So to sum up this thought experiment

Since movement depends on the observer, an object on the equator is either not moving, or moving

The speed and direction used when explaining it is moving

Can only be observed from an actually moving POV, but it is impossible for that POV to observe a constant motion of the object in regards to speed and direction

The direction of the theoretical motion is “East”, which is the real problem here

If you use the observer to define East, or rather it’s relationship to the North Pole, that same object which at the start is observed heading East, is going to be headed west in 12 hours

If you use the object to define East, or rather it’s relationship to the North Pole, which is what we usually do, then East constantly is a different direction for the object, which is really hard to explain

Unless you watch an animation of it from a POV, that does not show movement, but does show direction, and then your head explodes

### Re: The speed of an object on the equator of the earth

In any and all cases, the speed of an object on the equator is never 1000 mph East, except when you think it is

“I personally find it hard to believe that we are hurtling through space at 67,000 miles per hour on a big spinning rock. It doesn’t feel like it.”

https://scienceofdoom.com/2009/11/28/co ... -part-one/

That’s because you are not. That number is just a calculation based on a mental construct, just like speed of a point on the equator, or almost anything else somebody calculates based on time and distance

Motion is relative, you are not actually moving at that speed, just as you are not going 3 million miles an hour towards the great attractor

Even when we can calculate that according to an observer there you are moving at that speed

In reality you are not. This is the fundamental truth of motion. To an observer rushing past you in obit, you are moving at 24,000 miles per hour

Except in reality you are not

While the physics of CO2 absorption of a narrow band of IR that isn’t absorbed by water vapor is a different subject, the argument doesn’t hold up

Because if you don’t believe you are moving at 1000 mph, 24,000 mph, 67,000 mph, or a million mph, you would be correct
