Hello all. I'm quite new to this forum. I was wondering about the expanding or stretching universe. Can someone please tell me if my thoughts are correct and if not please correct me. The expanding universe. A common definition of the universe is everything. But if the universe is expanding it has to be expanding into something. Expanding into a larger universe maybe? But I believe that a more accurate description of the universe is stretching. You can see the universe as a collection of galaxies a certain amount away from each other. A theory I have developed is that maybe the universe is just stationery. But as time passes the space between each galaxy and celestial bodies slowly move away, this shows the stretching of the galaxy. According to Einstein's theory of general relativity we have to think of space as a much more complex entity not just a vast amount of nothingness. Incorporating his theories of general relativity space should be capable of "bending" and "stretching". If the space between celestial bodies are moving then what about the atoms, the building blocks of all matter. Maybe the spaces between them too are moving apart from each other. Or maybe its just the larger objects. Is the universe really powerful enough to rip the very fabric of everything we know into nothing? Does anyone know any recent research on this?
