Hello all, thank you for taking the time to read this post, i appologise if it is in the wrong section, as i am new to this. Why did people just invent Dark Energy to explain the accelerating expansion of the universe? I propose another idea that doesn't rely on fudging numbers to explain observation. As i understand things, space/time can be altered by gravity (warping) it. So objects near to a massive object appear to slow down (Time Dilation i believe?). As i understand, the universe is a measurable size, so it only contains a finite amount of matter (unless the Universe exists in a Steady State?). In the same way that a star collapsing becomes more dense, and consequently warps space/time more. Could you not argue that the Universe is like a star collapsing in reverse? Thus the Universe is becoming less dense, so altering how the universe as a whole warps its own space/time. Effectively what we measure as an increase in the speed of expansion, could be the fact that as the universe expands time flows (for want of a better term) faster. What im surgesting is that looking at the Universe from the outside it would be an expanding bubble, increasing at a steady rate. Inside our space/time expands, the universal gravitational constant decreases, allowing time to accelerate. I'm sorry if I'm not explaining very well, I'm not a physicist, so would welcome any observation pointing out obvious mistakes. Thank you for reading and i look forward to your responses!
