It's not really.Were orbiting the center of mass of the whole galaxy, Sagittarius A* just happens to be near there, but if it was to disappear not much would happen out this far.

Sagittarius A* is about 4 million solar masses, but there's possibly about 65 billion solar masses in other stars, then about a trillion solar masses or more in dark matter. We orbit around the center of mass of all of it, and so does the black hole which only makes up about 0.0004% of the total mass(though it could be located right at the barycenter?idk).

If you had an identical twin on Earth and Uranus, when the one on Earth reaches 70 yrs old, the twin on Uranus will be 1.1 second younger. Not including the time dilation experienced traveling to Uranus, but let’s say we have a transporter to blink us there.

There is an ergosphere around every black hole that extends past it’s event horizon. Yes, there would be time dilation, but it would become less extreme exponentially with the distance from the center of gravity.

But time is relative so to any observer on that planet, time would tick normal to them. We experience time dilation on Earth moving around the sun, and the gravity well of the sun too, but the time dilation compared to, say, an observer on Uranus is negligible. For example, time elapses on Uranus 59.99999997 seconds for every 1 minute on Earth.

So, the way you justify your own perspective is to dismiss everything I say on the grounds that 'This person who thinks differently than me clearly couldn't be an American because it's impossible for any American to think like that!'

Talk about being brainwashed.... The idea that you refuse to entertain the idea that Americans could see evil in their own government and refuse to support its actions speaks more to your propagandized and brainwashed ideology rooted in imperialist hegemony than anything moral or grandiose.

Anyways.... Enjoy your collapsing empire, bank failures, and inflation. I'll continue to live in the happiest country in the world. Cheers, mate!

Yes, there would be time dilation. How much depends on the distance the planet was orbiting. It wouldn't be close to the same amount of time dilation as Miller's planet unless you were somewhere between 1 and 2 meters from the event horizon, which isn't exactly a reasonable orbit for a planet.

Honestly, yeah. That's a great example. The issue I have is that people start trying to justify the actions of the serial killer they are friendly with and start trying to argue which one is worse.

How about we take a minute to stop and reflect that they both are serial killers and have done terrible awful things and let's move forward trying to not kill each other? Idealistic sure, but a better step in the right direction.
