That we don’t get dizzy…. at these speeds in the universe ???
I assume you’re just sitting around „somewhere else“ in a rather boring way. Idle hands are talking to you and you’re thinking…..
„Nothing going on, really boring“ !
Yes, think about it, relative to the sun, the true center of our Milky Way, neighboring galaxies and even galaxy clusters in the local universe, we are moving at an almost unbelievably high speed
Even if we don’t really notice it ourselves at first glance, our little blue planet (the size of a fly’s shit) – and therefore us (our bodies) – are moving enormously fast in space. Within one second you have already covered a lot of kilometers in the solar system. But that’s not all. You are also moving simultaneously through the galaxy and the galaxy, hard to believe, is racing through the local universe…
Pay attention, ask yourself the following question with a serious desire to know:
How fast does „Planet Earth“ actually rotate around itself?
But slowly, let’s first look at how we move on the surface of the earth relative to the center of the earth. Let me switch briefly to the German motherland, where we are moving on average one centimeter per year in an easterly direction due to „plate tectonics“. „It’s damn slow“. Continue to the continent „Africa“. It moves 2 centimeters per year, but to the north. ( uff, uff ) But now the following question :
Who holds the record for these movements? Yes, that’s the Pacific plate, it even manages 10 centimeters per year to the northwest.
It should be noted by me that these mostly unnoticed movements never end, do they ?
So there is another movement to consider. It is the rotation of the earth around itself. In our latitudes it is about 1,100 kilometers per hour. At the poles it is only 3 kilometers per hour, which is quite low, while at the equator (40,000 kilometers in 24 hours) it reaches 1,600 kilometers per hour. I would like to make an immediate comment, namely that our planet rotates around itself more slowly than it did a few hundred million years ago. …. I’m sure I’ll be saying it soon…..
Now let’s look at the sun, what is the speed of the earth around the sun?
These are quite different speeds! They are much faster. As perhaps everyone knows, the orbital period of our home planet is 365 days and 6 hours. If I can still do the math correctly, that’s one year.
The orbit around the sun is slightly elliptical but almost circular, … ..
It takes one year to cover this approximately 940 million kilometer long orbit.
To put it another way: the Earth and all 8 billion people on it move at an average speed of 107,000 kilometers per hour (29.78 kilometers per second). That means we travel no less than 2.6 million kilometers per day.
Great, isn’t it, I say that for all the ignorant……
What must also be said is that every celestial body has its own orbital speed. It is calculated from how long it takes the celestial body to cover its own orbit once.
Important: The further away the planets are from the sun, the slower they move. For example, Mercury is the fastest at 172,000 km/h, as it is closest to the sun. The outermost planet, that is Neptune, is only 20,000 km/h fast.
But it’s not over yet, we move differently…
How fast do we move in the Milky Way?
The Earth is part of the solar system and, like every other body in the solar system, orbits its star, the Sun… which moves around the galactic bulge, along with hundreds of billions of other stars. But for us humans, who are almost always disgusting, this journey takes an incredibly long time. The journey around our galaxy takes it about 230 million years (the sun is about 26,000 light years away from the center of our galaxy, which has a diameter of 100,000 light years). It was formed 4.6 billion years ago, so it has already completed 20 revolutions.
According to sources, the average speed in the Milky Way varies between 720,000 kilometers per hour (200 km/s) and 900,000 kilometers per hour (250 km/s).
Why don’t we realize this speed?
Anyone who has been brought up to believe in a god or similar nonsense for their entire life has a particularly bad hand in this question. It can only look very silly.But if you know that the Earth is constantly in motion ➙ both in its rotation around its own axis and in its orbit – the question arises with countless of the above described: Why don’t we notice the speed? The simple and dry answer is …..
Because everything rotates!
This can be easily illustrated and the following example, which I hope is simple, may help „them“: In a moving train or car, you only notice the speed by the fact that trees and houses pass you by.
If, on the other hand, you are sitting in an airplane (which is often much faster than a train or car) and all you can see is the blue or dark sky, you don’t notice the speed. At most, you notice the engine noise.
Due to the earth’s gravitational pull, „everything“ is completely attracted to the earth. Even the clouds and the birds. Everything turns with the earth and there are no engine noises or anything similar. You can imagine that there is a large balloon around the earth – our earth’s atmosphere, which is filled with air. This balloon is constantly spinning – both in a pirouette around the Earth’s axis and in orbit around the sun.j
