If it turns out we aren’t alone and there is a galaxy full of other species interacting like The MCU, What would we do?

Like would we put more funding into nasa or something or would we try to stay out of everything else? And would civilians have opportunities to move to different planets?

Galaxy s20+ physically interacting with a game card??

Hello all!

I was doing some random shit at home and sat my phone on top of my wallet- my phone vibrated and beeped. That's never happened. I did it on the right side of my open wallet, nothing. I did it on the left, it vibrated and beeped again. I went through card by cars and it turns out it was a chucke e. Cheeses game credit card I had just got earlier in the day. There must be something in the card, but it looks like a regular flat piece of plastic with a strip. Anyone know what is causing it? Google isn't helping me any. I can post a video if anyone is interested. Tripped me out. I have an otterbox defender case and it still picked it up.

Hypothesis: the Nile Galaxy is an interacting galaxy

The Mice Galaxies. The tidal \"tails\" of stars dragged out from the spiral galaxy by the little elliptical galaxy (the featureless blob) are maybe 750,000 light years from tip to tip, eight times the diameter of the prominent disc of the Milky Way.

The Nile Galaxy is pictured as a spiral galaxy in diagrams; however, the "Nile" moniker, is suggestive of a long, thin object. While this fits the description of a spiral galaxy viewed edge-on from some distant point in space (the Needle Galaxy is a good example), a more intriguing and compelling idea presents itself... if you allow for the possibility that the diagrams have been cropped.

Tidal interactions between galactic near-misses and collisions have been known to generate tidal "tails" from galaxies, vast filaments of gas, dust, and rapidly forming stars hundreds of thousands of light-years** in length. Over the half-billion or so years it takes for a galactic flyby, shockwaves propagating through vast clouds of dust and gas trigger bursts of star formation, seeding galaxies with the heavy elements of life and civilization, and setting night skies aglow with carpets of blue-white giant stars amidst vast sheets of gas and dust (plus the occasional supernova).

Such a magnificent structure would most certainly deserve the Nile moniker, and the unique astrography and rapid star formation of a galaxy enmeshed in a collision would make for magnificent worldbuilding, setting, and scenery.

*Note: for an sense of scale and wonder, note that the Milky Way contains 200-400 billion stars (and, judging from Kepler's results, over a trillion planets. They're everywhere.). All the light stuff masses somewhere in the ballpark of 200 billion suns, with the dark stuff (the "dark matter" they keep talking about) massing over a trillion suns. This is so many suns that you could build a billion warships, and each warship would still have to patrol a few hundred star systems. A lot of galaxies are smaller than the Milky Way, but not by much (discounting dwarf galaxies).

**A light-year, for those unfamiliar with the term, is the distance light, that sluggard, travels in one year; approximately ten trillion kilometers (the Earth is thirteen thousand kilometers across). The sun weighs in at two octillion tonnes (two billion billion billion tonnes) .

Physicists explain mysterious dark matter deficiency in galaxy pair. UC Riverside-led study found self-interacting dark matter theory explains why a pair of galaxies about 65 million light-years from Earth contains very little of the mysterious matter.

This is the best tl;dr I could make, original reduced by 68%. (I'm a bot)


> A new theory about the nature of dark matter helps explain why a pair of galaxies about 65 million light-years from Earth contains very little of the mysterious matter, according to a study led by a physicist at the University of California, Riverside.

> The prevailing dark matter theory, known as cold dark matter, or CDM, assumes dark matter particles are collisionless, aside from gravity.

> A newer second theory, called self-interacting dark matter, or SIDM, proposes dark matter particles self-interact through a new dark force.

> Both theories explain how the overall structure of the universe emerges, but they predict different dark matter distributions in the inner regions of a galaxy.

> Typically, a visible galaxy is hosted by an invisible dark matter halo - a concentrated clump of material, shaped like a ball, that surrounds the galaxy and is held together by gravitational forces.

> In CDM, the inner halo structure is "Stiff" and resilient to tidal stripping, which makes it difficult for a typical CDM halo to lose sufficient inner mass in the tidal field to accommodate observations of NGC 1052-DF2 and -DF4. In contrast, in SIDM, dark matter self-interactions could push dark matter particles from the inner to the outer regions, making the inner halo "Fluffier" and enhancing the tidal mass loss accordingly.

Yes, i'm aware that that's a lot of tabs, which i've cut down to 30, but with no change. Resetting the device doesn't do anything to help either.
