I am sorry, i have misquoted of ursa mayor distance from earth. That distance in post #4366 might be the ursa mayor span distance.
Has Light got a decay factor?
Another perspective is that the actual border of the universe is only around 3666 light years away. Combine it with time arrow or our consciousness then universe might look exceptionally huge. Think about it.

The latest research still can't detect "Dark Matter". The logical answer would be to abandon the Dark matter theory altogether. It's been decades since they started looking. Umpteen research facilities across the world have tried and failed to detect it. There are some who have dedicated their whole professional life to finding it. But are they downhearted? NO...they're going to throw more money at it until the results fit the theory. The universe is supposed to be made up of 80% of this stuff...or is it 70% or 23% or 90% ? Nobody knows.... 'CUS IT DOESN'T EXIST
What about Cherenkov phenomena.It seems involving faster than light speed.

In the part of (T0001) Time ,there is a reason for Time contraction rather than Time dilatation.Thus faster than light speed could be possible.

More grease to the Unified model

Big Bang wrong again. It's not just me saying it. It's just not enough anymore for the scientific community to keep saying " there's nothing better" . That's just BAD science.
....and u&I know that's EXACTLY how science goes sidewayz

I feel that we should pick this up again later when I'm @ the Electrical Banana....pulling on the straw of a striated Sunset Tequila

"Big Crunch" is an old idea, which isn't necessarily inconsistent with a Big Bang, tabloid articles aside.

There is confusion in redshift causation.This thread is meant to discuss that causation which is different than general accepted idea.
