How Fast Is Earth Moving?

All this movement is why a time machine would have to be a very, very fast spaceship. One miscalculation on speed and you’ll be millions of miles from earth.

it’s all relative to the frame of reference.

Dear DannyTN,

Please don't be like so many other Flat Earthers that show up here. LibWhacker is trying to inform you that youtube video does not necessarily equal education, and in this case he is correct.

Physical laws of motion like Newtons laws, or Keplers planetary motion, work in an inertial frame. These laws, which start out as theory, get 'proven' or disproved by experiment and measurement.

We have known for hundreds of years now the planets orbit the sun because we can observe their motion, and predict their motions, using Keplers laws and Newtons laws.

Saying that it all revolves around the Earth, since as you say it all relative, would void all these laws. The other planets would no longer move in predictable fashion, and a great many other things we can observe and measure would be unexplainable. The mass of the Earth could never hold the mass of the sun in orbit for example.

Just sit back and enjoy the ride…

I wish I could find it, but there was an interesting article about our universe in motion. Basically the author said that all motion is relative and based on arbitrarily selecting a point and measuring motion from there.

With that in mind, it was asserted that picking earth as the point of reference was just as valid as picking any other point - thus the universe revolves around the earth.

He said it much better than I, but you get the gist.

Lol!

Thanks - She’s in west NC - Sylva area so they’ll get a lot of rain but I think they’ll be alright.

For all the east coasters (1 million+) being evacuated I do wonder where they’ll go? That’s a lot of motel rooms, I guess you just keep driving west til you find one.

Yes, the sun wobbles as the earth goes around it (has nothing to do with relativity, afaik).

And we can use earth as a frame of reference (has a little more to do with relativity).

But a look at the equations of orbital motion tell us what is really going round what.

Is the earth going around the sun as it is yanked along by the sun in its approx 600 million mile orbit around the sun? Or is the sun going around the earth as it wobbles along in its approx six foot long "orbit" around the earth (I'm assuming a wobble of approx one foot either way)? Could the earth even fit inside that "orbit?" No.

So the equations of orbital motion give us a way to distinguish a real orbit from a six-foot-long imaginary orbit (it's a real wobble, that's for sure, but that's all it is), as if we needed it.

Too fast to get off. Try it and you’ll get a road rash like nobody’s business!

[DannyTN]

Well at least you presented an argument.

I agree that the idea that the sun and the universe revolving around the earth throws a monkey wrench into the way we understand things. But I think most of the laws would work the same regardless, except that we would have no explanation of why everything revolves around the earth.

We have mass to explain all the other motion. The other planets would still predictably move around the son according to the mass based laws of gravity as we understand them. But why would the earth be pinned and the Sun and the rest of the universe revolve around it? Certainly not because of mass.

I was really hoping that someone would explain why the video claimed the need for dark energy would go away.

And I don’t appreciate being called “other Flat Earthers”. I’m not a flat earther. That was a term generated by evolutionists to discredit creationists. I never claimed to agree with the video. And while I do believe in scripture the oldest book in the Bible, Job, speaks speaks of the earth being round and that God hung it upon nothing.

It makes for really tough navigation of my time machine.

Didn’t some NASA geek miss a decimal point calculating a conversion from English units to metric, ruining a trip to Mars a while back and resulting in a loss of a space probe?

Rocket surgery is hard!

The video is “The Genesis Theory - (Part 1)”

The part about the Heliocentric model begins 2 hours into the video and the next 30 minutes is pretty interesting.

The first video is 3 hours, the 2nd is 5 hours. The third video he apparently never made.

He says at the beginning that he intends to first introduce creationist concepts, then a number of scientific theories that are not discussed much. And he intends to pull those theories together into a unifying picture that presents an alternate cosmology that supports creation.

He spends about an hour and a half introducing creationist views, using scripture and a lot of Kent Hovind clips as well as others. Then he introduces some Flood information and some Egyptian creation myths.

Two hours in, he gets into the astronomy, with challenges to the heliocentric model. Presents the claim that cosmic background radiation indicates the earth is at the center of the universe. Then he pulls out some Eric Dollard and Tesla.

3 hours of material, I’m sure it’s target rich. Hey but so is science. For every hole you might be able to shoot in this guy’s presentation, I’m sure I can pull out past episodes of scientific global warming/cooling/warming/cooling/warming, pithdown man, blood letting, historical medical treatments of female hysterics, scientific geoupthink and ridicule of theories eventually proven correct, etc.

So both sides are target rich. Try to keep the discussion logical and to the facts.

Good memory!

NASA says the probability for Earth stopping its spin is "practically zero" for the next few billion years... What if the process was more gradual? This is the more likely scenario over billions of years, NASA said, because the sun and the moon are tugging on Earth's spin. That would give plenty of time for humans, animals and plants to get used to the change. By the laws of physics, the slowest the Earth could slow its spin would be 1 rotation every 365 days. That situation is called "sun synchronous" and would force one side of our planet to always face the sun, and the other side to permanently face away. By comparison: Earth's moon is already in an Earth-synchronous rotation where one side of the moon always faces us, and the other side opposite to us.

The process at work there is called the tidal transfer of momentum; the rotation of the Earth slows as it pushes the Moon away, and the Moon, being about 1 percent the mass of the Earth, did the same until it ran out of rotational momentum. A satellite in retrograde orbit, by contrast, gets pulled down toward the parent body.

The Sun, though more distant, is doing the same to the Earth, with about half the effect that the Moon once had (when the Moon was tidally transferring momentum, the Moon was pushing the Earth away, as the Earth was and continues to do to the Moon) because of its much greater mass. Similarly, the Sun contributes about 1/3 of the tides, which is a real squirt of lemon juice into the eye of anyone who takes the book "Rare Earth" seriously.

At some point, if the Earth continues to push the Moon away, there will be a bad crazy period as the Moon slips the surly bonds of Earth, because the process won't be instantaneous, due to the slower velocity of the Moon as it rises in average distance in its orbital path.

Thanks ETL. Ping to the APoD list, along with the Catastrophism list.

Yeah, well, it is that sudden cessation of spin, where we all go flying that will be the pits.

That and all that ocean water sloshing around.

Best to be in orbit or on an airplane when it stops spinning. Slamming the brakes on at 1,000 mph could be painful.

Good read. Thanks for posting it, ETL.

Most people don’t have time to view 3 hour videos just to try to pick them apart. Why do you want others to do this ‘work’ for you? Similarly to LibWhacker, I have got other things on my plate. And while there are still mysteries to Gods great universe, nothing from Big Bang and the physics we know is incompatible with creation theory, as long as you don’t try to lawyer Gods word.

“Indicating the earth may be the center of the Universe.”

I do not know about physics but philosophically speaking, in an infinite universe the center is wherever you are because all interior points are an equal distance from the edge. Thus you are always in the center, no matter how far you travel.
