Gravity is way too weak a force to hold something as massive as a galaxy together.

Well it obviously does. If not gravity, then what ?

No one knows. But you are never going to find the answer if you keep inserting explanations that make no sense.

Isn't there two other forces ... Centripetal Force and Centrifugal
Force, or some such?? One acts to try to pull an orbiting object towards
the centre whilst the other acts to force the object away from the
centre. When the two are equal (or is it "close to equal") the object
orbits the centre.

Lots of things go faster than 186,000 miles per second.

OK, so name just one.

Matter from exploding stars; some rogue planets--especially ones knocked free from close to their stars.

I'm not sure about 'exploding Star matter" but there is something that
travels faster than light ... the stuff for which scientists place
detectors deep down mines. Is it quarks or some such?

But when something goes that fast it exits the universe--that is why it cannot be observed.

What are you talking about ?

Traveling to distant stars fast enough to get there puts you in another reality that is not in the universe and does not apply to its rules. Space debris and cosmic rays cannot harm you in this state.


Your problem is that you are trying to talk according to the system. The system does not function. It never did.

I saw you mention the "system" in an earlier post. What system ? What
are you talking about ?

Man's language makes no sense. People think they are making sense but they are not. No one has the will or inclination to pursue a thought or answer through to its successful completion. So it ends up that no one knows anything.

Man's language makes sense to most people that know how to use it properly.
