It will reach c, the “speed of light,” the default speed of the universe.
This is incorrect. Light speed is the default speed of EMR.
We are observing outward scalar motion between all points from the perspective of a fixed 3D spacial reference frame that we call reality. We are inside a gravitational limit. That motion is scalarly away from ALL points (conjugate of gravity).
That statement assumes that gravity is the fundamental force of the universe. It is not.
This has been addressed. Doppler shift, Red shift, same principle, are explained by motion in time in addition to motion in space.
That statement assumes time is a constant and that it is consistent. It isn't and is not.
I would suggest you stop arguing why something can’t be and start asking ‘HOW can this be?’
That statement assumes that such a postulation has not taken place. It has. It also assumes that General and Special relativity are perfectly correct. They are not.

LOL! Yeah, they're a bit far away to be of any worry for the people of planet Earth. ;)

The only things i worry about in terms of Space is a non discovered asteroid hitting us from the influence of Jupiter, a comet coming from the Keiper belt and hitting us or (not really a concern for me as I use landmarks) a CME destroying the GPS satellites that so many people depend on for navigation...especially those self driving cars.

Haha true. Few billion years from now our galaxy and Andromeda will merge and so will their central black holes. Shame, we won't be there to see it.

And that is very likely to happen. Solar Flares are a very serious threat to Earth and hit us regularly. Unfortunately going to take one from us to learn our lesson, but I imagine it will only take that once.

THAT would be a sight to see!

Yep the sun even sent us a flare a couple of weeks that you could see from Toronto Canada which is 2917 miles south of the North Pole. I totally agree with you that modern society is addicted to the convenience of technology but something like GPS being destroyed would force a refresh back to lack of a better word analog or actually using your eyes and memory for navigation.

Black holes are really fascinating. It's gravitational force are so strong and it's very scary to have even a very tiny blackhole within our solar system. I hope the scientists will get to have more information about the mysteries surrounding this space matter.

Yes as fascinating as black hole bodies seem to be , even math has a hard time decrypting such celestial bodies.
I got as far as Plank density.

This sounds so cool!



If a passing photon is a bit too close, it will get trapped in orbit around the black hole. This creates what is called a "photon ring", a perfect ring of light predicted to surround the black hole, inside the inner rim of the accretion disc, but outside the event horizon.
Models of the black hole's surroundings suggest the photon ring should create an intricate substructure consisting of infinite rings of light.
Each successive ring becomes increasingly sharper because its light orbited the black hole more times before reaching the observer.
Hence, in an idealized setting with no absorption, each subring contains a separate, exponentially demagnified image of the entire Universe, with each subsequent subring capturing the visible Universe at an earlier time. Together, the set of subrings are akin to the frames of a movie, capturing the history of the visible Universe as seen from the black hole.

The OJ 287 galaxy hosts one of the largest black holes ever found, with > 18 billion times the mass of our Sun. Orbiting this behemoth is another massive black hole. Twice every 12 years, the smaller black hole crashes through the accretion disk surrounding its larger companion, creating a flash of light brighter than a trillion stars.

The interesting thing about that galaxy is that because of these events chemical based life is very unlikely as the EMR pulses would ionize the atmosphere(not to mention literally cooking the surface and boiling bodies of water) of any planets within 30,000ly(approx) radius and saturate space with gamma and xrays for another 25,000ly(approx) making the inner areas of that galaxy uninhabitable. OJ287 is a larger galaxy than the MilkyWay, so the outer areas might still have the possibility of life.

@lexluthermiester Yes, galactic centers and regions close to supermassive black holes are quite extreme. Regions around giant stars and star clusters aren't really nice either. However, type 2 and 3 civilizations might have technology to withstand all that craziness and even harness that energy.

Possible of course. However, the intensity of that kind of radiation can not be understated.

I have to chime in with that and remind myself that we get cancer from a little too much sun, let alone the extremes of a galactic centre. Space is a hostile environment, that's for sure.

There's awesome hard-sci-fi book called Dragon's Egg. It's about intelligent creatures inhabiting neutron star. They're made of neutron matter and can withstand enormous gravity and radiation.
We don't know much about consciousness but imagine if such creatures can exist and they have consciousness and they can live anywhere in the galaxy. I know I digress but hypothetically that'd be pretty awesome.
