What if the galaxy is not being pushed apart from a single point, but instead Beng pulled apart by a series of Black Holes?

It's not being pushed apart from a single point. Space is expanding at every point that is not gravitationally bound.

If it were being pulled apart by black holes, there would be evidence for it. But there isn't. However there is evidence that it's expanding.

What if we only see space expanding because we are actually being sucked into a black hole ourselves. Sheeeeit....

You would have to be immortal to see to infinity, so yes if you only live a limited amount of time you would not see all of the universe. You would appear to be in the centre of the universe no matter where you view from as the light from the farthest reaches takes time to get to you. That is to say if the universe is infinite. If it is finite then you would see the edge if you are located near it (according to theory that is 13.7 billion light years away). But all of this is based on time and our gravity; somebody else might have a different scale for time and therefor light would be faster or slower if they are to use our unit for time, but they might see time as irrelevant as opposed to our understanding which is relative. If they see it as relative they probably have there own unit for time and scale. Our units are based on mass (how long it takes for us to travel around our star and how heavy is a kilogram under earths gravity**) so if they see light as a consent which is debatable i.e. gravity bends time/light see: Gravitational time dilation. If you really wanted a true constant for light you might have to measure it without gravity, which is pretty much impossible as the known universe is littered with gravitational bodies that bend light/time and because the furthest reaches of the known universe has to travel through so many gravitational anomalies a lot practically all of which are not known, the observable universe's age could be very inaccurate.


If the universe is stationary then 100 years from now more light will reach us and so the "infinite universe" would appear to hold grounds, however if what we see today disappears in 100 years then it either is expanding or we are shrinking. If it is shrinking into the super massive black hole said to be at the centre of our Galaxy then the expansion theory would still hold but only because time and gravity we perceive are getting longer and stronger. But either way there is no way to tell as in theory nothing can escape a black hole, but we might not be past a point of no return if that is the case. If we could travel to the space between our Galaxy and Andromeda to a place where there is no gravity to influence time in a straight line between the two or to a point in the observable universe then all of these theories could only truly be tested. To steal one from someone... "We could all be just observing this from the grout in someones bathroom tile...."

this is a tangent!!!
**unit of length is based on the diameter of Earth, mass or kilogram used to be based on the volume of 1 litre of water - 1 cubic decimeter. Bit of an issue with weight because when it was first measured it was not known that when water is at different temperatures it weights slightly more or slightly less. IIRC the exact temperature of the water was not recorded neither was air temperature so depending on how well the measurement was recorded it might have weight more or less than previously recorded, if any, depending on how much water evaporated as well. Somebody else's star or stars might be more massive or less massive than ours and their planet might be bigger or smaller than ours. So if they came up with the same measurement of time as we did, which is.... The Sumerians passed down to Babylonians, base 60 system (or as I like to call it sexageussimal system) this measured how many arcs it took to travel the distance around our sun and dividing by 60 to get time. 60 is/was their max number (not literally - segments of 60, we still use it for degrees of a circle 60 * 6 ... 360 they would have found that there was a remainder so decided 1 week will be based on the Moon phase which is why there is 7 days in 1 week and 4 weeks in the month etc they used leap days to even out the calculation of the sun. The Romans had 8 days in 1 week until they encountered the 7 days a week and decided to take credit for them and name the days after Roman Gods. Interestingly in most languages it is the same...

Once in a blue moon has a good story to it.... here

There is a blue moon at the end of this month (2 full moons in 1 month)
