If the singularity of a black hole can absorb infinite mass and energy, what is stopping one from just devouring the entire universe? If nothing can escape and nothing can stop them, shouldn't they be like the drains in a filled bathtub with us on the surface of the water?

...I know little about them. In my life I have been fortunate enough to see many falling stars (shooting stars) and actually sat staring at an odd looking star once only to see it streak across the sky. My question, just how fortunate am I? I'm not an astronomer, nor do I look through telescopes, I'm curious to know if the average person has seen as many as I have which is probably three to five a year. Don't ask my age, let's just say it's a lot!

I have read time and again that the speed of light is the maximum speed limit of the universe. In our limited understanding of the universe, is it possible that dark matter exists beyond the speed of light and therefore is "dark?"

I am a novice but I do understand many of the Scientific Theories (big T!) out there. This would make sense as to why it is dark. Could we be wrong about the speed of light? Is it just another barrier like the speed of sound once was?

Either stop us from reaching each other.
Or to challenge us to one day reach each other.

*I'm working on the assumption that the universe was created and there is other life outside of ours!*

The tripod seems problematic in its tendency to wobble and require counterweights. How do you make a solid platform/stand and mount system without a tripod, a dobsonian mount, or any need for counterweights (like the dobsonian, except star tracking)? Where can I find plans on how to build one? The purpose is to avoid vibrations, track stars, and avoid costly materials/products like equatorial mounts. I want to use simple, inexpensive materials and tools available at Home Depot or Lowes.
