How fast am I moving right now

How fast are we moving through the universe?

Our blue planet rotates to the east - and this at a speed that is 1,674.3639 km / h at the equator (however, it decreases significantly towards the pole due to the decreasing circumference of the earth there) [see]. The planet earth itself in turn does not stand still in space, but moves relative to our home star "sun" with a clockwise orbit speed of an average of 107,229 km / h around the same [see]. And finally, the entire star system “Solar System” belonging to the star “Sun” orbits the galactic center of our cozy galaxy “Milky Way”; it spends the time of an entire galactic year for a single orbit - the equivalent of around 210,000,000 earth years. And the movement is by no means leisurely, but rather with a proud circumferential speed of 961,200 km / h [see].

Our galaxy “Milky Way” as a whole is meanwhile racing relative to the next larger galaxy cluster structure “Local Group” at a further 136,800 km / h through its seemingly astronomical expanses.

And the “Local Group” cluster of galaxies, what a surprise, doesn't allow itself a break - and rushes through the realms of the “Virgo Supercluster” [see], which is also a part of the Filament is "Large Attractor"; one of the most massive known structures in the universe with an estimated mass of 10,000,000,000,000,000 [10 quadrillion] suns [see].

Considered relative to the cosmic microwave background radiation - an isotropic radiation relic that emerged 380,000 years after the Big Bang - and regardless of the various other speeds just mentioned, all of the objects mentioned move together - and thus we too - through the universe at an additional 1,987,000 km / h per se [see]. (Although the background radiation reaches us from all directions; however, its relative speed can be calculated using the Doppler shift of its frequency - Sheldon will be pleased [see]). We are in good shape.

So. Can all these numbers now simply be added up and thereby an overall speed of our position can be determined? Nope. On the one hand, it is not just matter that moves through space, but space itself - that is, the universe - itself is constantly changing its dimensions; it expands in all directions at the same time relative to us. Not constant, but faster as the distance from our observation point increases. The speed for this can be calculated with the Hubble constant: 70 km / s / Mcp (70 kilometers per second per megaparsec, whereby one megaparsec corresponds to a length of 30,860,000,000,000,000,000 [30.86 trillion] kilometers). In other words: An object, for example a galaxy at a distance of one megaparsec, is moving away from us at a speed of 70 km / s or 252,000 km / h due to its constant expansion, whereas a galaxy at a distance of 2 megaparsecs is already moving away at 140 km / s or 504,000 km / h. In about 2,000,000,000,000 [2 trillion] years we will therefore no longer be able to see stars and galaxies outside the local group, since their emitted infrared and gamma waves then propagate more slowly as the universe expands [see]. Nonetheless, individual objects can migrate in our direction due to their higher speed, such as the Andromeda Galaxy, which races in our direction at 1,080,000 km / h and in 4,000,000,000 - 10,000,000,000 [4 - 10 billion] years with our Milky Way a new galaxy will merge [see & see also]. Relativity as far as the telescope can reach.

On the other hand, the different speeds of the astronomical formations sometimes cancel each other out. For example, if our star system moves within the Milky Way at speed Q in direction A, but the Milky Way as a whole moves at the same speed Q in the opposite direction B, the bottom line - viewed from the outside - is that we make a pilgrimage with an overall speed of zero.

In summary, we turn quickly around ourselves, move around the sun, at the same time around the center of the galaxy, but at the same time move closer to the center and away again due to various gravitational forces as well as up and down, wandering through the Milky Way as part of the Milky Way Galaxy cluster of the local group in direction C, which moves in the Virgin super galaxy cluster in direction D, while the space itself around us is constantly expanding and expanding in all directions away from us. The definition of a final speed is therefore not possible due to the many contradictions and relativities; we can only look at the individual speeds separately and soberly discover that we are - in a nutshell - extremely fast?
