Every star in the sky is interacting with you through gravity 🌌 We are all connected to the universe around us.

  Any given star is constantly emitting an unimaginably large, but finite, number of photons. A tiny few of them travel tens to hundreds of (Earth) years, only to end their journey in your eyeballs.

    Even crazier when you consider how long that photon bounced around inside the star before escaping out into space

      Technically the photon is being absorbed and re-emitted inside the star, so it's not exactly the same photon.

    Screw photons, neutrinos are where the real numbers start racking up

    And from the photon’s perspective, it all happened in an instant 🤯

  They’re also exerting a minute amount of electrostatic attraction or repulsion.

    Amazing. Thanks for sharing!

  Technically correct, but the gravity from stars is dwarfed by the gravity from yo momma.

    Actually tru for every value of yo mama, from s to xxxxxxxxxl

  While that’s technically true, it’s good to note that this doesn’t excuse astrology, which is based on the false fact that the gravity of celestial bodies influences our decisions in everyday life. The gravity of you Karen influences my “daily life” more than these celestial bodies and especially your belief in astrology. 😄

    Agreed 🤝

  So, horoscopes are true? /s

    While you are affected by gravity, it’d have less of an effect than other things.

    For instance we can scientifically show your birth date does influence your personality, as long as you don’t live on the equator.

    The further North/South you go, the more pronounced the effect becomes.

    That is to say that from large samplings, you can see that extroverted traits are more common with babies born in Spring (in the Northern hemisphere), while introversion is more associated with being born in autumn.

    That ofc doesn’t mean that a person who was born in November will automatically be less extroverted than one born in March, but if you pick two random people from those groups, it’s X% more likely that it is so.

    Astrology is complete fucking bullshit though.

      I know. That’s why I added the “/s” tag.

  Wait, I thought gravity is not a “force” but the curvature of spacetime, so at some point the curvature gotta end or be disturbed by some other source nearby, right? A star so far away is not exerting any “force” on me as I already have two massive objects Earth and Sun twisting the spacetime around me so much. I could however be getting some gravitational waves from that star but not sure how strong they’d be or if they reach me at all (again given Sun and Earth).

  (NOTE: I’m an engineer not a physicist so my understanding could all be wrong)

    You're partially right. Gavity has infinite range, so a distant star does exert some force on you. And that force is present regardless of other gravitational fields like the Earth or Sun. However it's many orders of magnitude weaker than the force from the Earth and Sun so it's pretty much irrelevant.

    Eh. It’s not really a definite distinction. Even in GR you formulate effective potentials and the gradient on those potentials are still called forces. Then, what is a force on microscopic scale? It is the exchange of force mediators, like photons. If gravitons exists, then there is even a similar framework for defining a force on a microscopic level for electromagnetism as well as gravity. Furthermore, electromagnetism (qed) also has an interpretation as a curvature, as it is a gauge theory, just not a curvature of physical spacetime, and that does not disqualify if from being called a “force”.

    With gravity wave detectors we are able to measure gravitational waves from two merging black holes distorting space-time even here on earth. The distortion is less than the width of the nucleus of an atom.

    Are you trying to say the people who spout generic bullshit about humans wrapped into arbitrary boxes are somehow related to actual physics where people do falsifiable experiments?

    Because astrology didn't predict shit.

    • rockerface@lemm.ee ⁨8⁩ ⁨months⁩ ago

      Astrology was just a way for astronomers to earn a living in the age when people didn’t care about space. So there is overlap in that the same people would often practice both

    Why so unnecessarily aggressive

  • vatlark@lemmy.world ⁨7⁩ ⁨months⁩ ago

    This is an interesting perspective and could have resulted in interesting discussion. Aggression alone isn’t bad, but attacks on posters are bad.

  Well, Proxima Centauri better stop pulling on me or I’m going to smack it.

  And they call it the weak force. Bah!

  source

  • hperrin@lemmy.world ⁨8⁩ ⁨months⁩ ago

    Gravity is different than the weak force.

    source

    • Kolanaki@yiffit.net ⁨8⁩ ⁨months⁩ ago

      A weak force? I know I’ve heard gravity described as the weakest force before… But I also got a D in physics so… 🤷🏻‍♂️
