Questions????
Statements:
​
You are a fly.
​
You are flying about in a car.
​
The windows are painted over and you cannot see outside the car.
​
You can see what is inside the car.
​
Questions:
​
Can you tell if the car is sitting still or driving at a constant rate of speed on a super smooth highway?
​
Why do you never see bugs smashed on the inside of the windshield?

Re: Questions????
A few questions.
​
Why do you think the most distant stars would be near the edge of the universe?
​
Since we can see back at leat 14 billion years in time, why have we not seen both your stars suddenly forming at one point and suddenly disappearing 180 degrees away?

Re: Questions????
Firstly constant motion is just a relative concept - at least with the car there is the issue of acceleration which legitiamtely lets us say that it is the car that is moving.
​
That is why I removed acceleration from my example.
​
Secondly there is the problem that it would be SPACE itself that would have to be moving for the idea to make any sense - and so far as I can tell that makes no sense either...
​
That is why I made the universe a closed system. With all of the windows painted we canot see or sense anything beyond the hypothetical universe, which is actually the situation we are in.
​
I believe that it is time for nipok to visit Flatland

Re: Questions????
When you look at stars and galaxies, are those furtherest away actually near the edge or simply older? Are you looking away, or back in time? Is there any reason to think we are not on the edge of what you call the bubble?
