Why did all of the material in those two spiral arms lose all of their angular momentum and head for the core at the same time? I bet those two hard right turns those arms tax are separated by 15-20kpc. Since so many galaxies do this, whatever is happening to this one must be pretty common.
Also check out all those galaxies buried in the background, there must be some kinda awesome galaxy cluster back there.

the magnetic field created by any active galactic nucleus should be radially symmetric with respect to the axis of rotation so if barred spirals are caused by active galactic nuclei which are off axis from the host galaxy's rotation by 90º or so and the observed probability of off axis galactic nuclei should predict the observed frequency of spirals with bars.
i don't know if it does or not

I've been drinking, so I'm not going to check if your theory is accurate or not... but I will point out that you forgot one thing. You forgot to include the relation of the galaxy to other fields such as those manifesting from other galaxies. (though honestly, I suspect that magnetic fields aren't generated from a source directly, if this makes sense. Think of flowing water. A whirlpool in a stream is not generated by the rocks below it, it's simply directed into this form by them. If this does not make sense, I will respond eventually while not drinking.)

First one is Saturn's Hexagon on its north pole.
Essentially formed because of a turbulent storm near the vortex creating two weird waves that makes hexagons naturally.

lets say you were somewhat nearby a rapidly rotating neutron star such that the star's diameter was a significant portion of the distance from the star. Would the star's effective center of gravity be offset towards the approaching limb because of the relative velocities and redshifts of the approaching side versus the retreating one?
If its real, how significant would the effect be? Does the effect imply that the gravity well isn't symmetrical?

With respect to the receding limb, as the mass is accelerated away from the observer at relativistic speeds, the mass exerts less gravitational influence because of the redshift. The receding limb appears to effectively lose mass as well as getting dimmer and cooler. Could that effective loss of gravitational pull due to the acceleration be considered "anti-gravity" and if so, what potential uses could be made of a propellant based propulsion system in which the propellant reaches relativistic speeds?

I'm scared guys. This could mean life is common in the universe, which means the Great Filter is ahead of us instead of behind us.

😰😰😰😰😰

Then again, maybe this can show us the Great Filter is already behind us but when it comes to cosmic horror, I'm a half-empty kinda guy.

Even in the case there will be evidence in the geological records.
A layer unusually high concentration of iron compounds and scattered refined metals everywhere. Evidence of mining on the layers below.
I can't come up with a complete list but I've seen somebody do it, perhaps I'll find that again.
In the case of "turn the entire crust into a molten fireball" of course life itself would vanish and the atmosphere would be heated so much that it would be blown away into space.
This would paradoxically make it easier to preserve evidence of our civilization since stuff can't oxidize.

This doesn't mean a large enough chuck couln't do it though. With enough kinetic energy the upper crust could evaporate too and be blown away into space.
It would have to be an extra-solar object though since we are pretty much certain nothing of that magnitude is around as far as we can see.

We've pretty thoroughly contaminated it already though. Considering that even the exterior of the space stations have microbial life on them, and how impossible it is to irradicate every spore and microbe, the red planet is likely already colonised with lichens, puffballs, and extremophile bacteria. It's going to be a long hard journey to determine if the life we find on mars had existed before our modern arrival, unless we manage to find more complex life forms than bacteria and fungi.

Throw that meteor hard enough, and there won't be any fossils left. Everything will turn into molten rock.

After meeting our god I asked about women and he sent me traveling outside to where their creational black crystal resides. I got to know them, then after some time, both collectives let me as a male, and a female from their's, to travel to the central black hole where people reside to learn and get to know everyone. The behavior from the opposite female was so vibrant I couldn't let her near me until her mind was less flippant, so I created a string between us she had to travel up before meeting me. It almost choked her assertive behavior until she understood where I was and we met up the right way.

I was listening to an episode of "The last podcast on the left". They were talking about the WOW signal.
If you aren't familiar LPOTL is a bit like coast to coast AM but hosted by some guys who are actual skeptics and fun. So some of this may not be accurate but its fun to think about.

They were saying that if it was anything intelligent broadcasting that we only got a snippit of the message because at the time scans of the sky were limited to rotation of the earth (they used the number 72 seconds but i have a feeling that was an approximation), then later when the location of the signals point of origin was found it was a region of space with no stars or really any thing at all.

The hosts speculated also if it was intelligent due it being in that really empty place in space and then we never saw it there again, it's likely the sender were simply in transit some where and we picked up some distant comunicqae of a "passing ship i nthe night".


although its like 900% more likley to be random noise or a misinterpreted signal from earth/[%]
Thats so wonderful and creepy at the same time.
It gets my dick rock hard
