Universe EXPANDING FASTER?! | NOVA | PBS

NOVA PBS Official | June 16, 2026



When scientists measured distant supernovas in the 1990s, the data made no sense. The universe wasn’t slowing down. It was accelerating.

    Every energy producing object in the universe is expelling a sphere of energy that expands forever out into the universe. All of those expanding spherical shells of energy are themselves perhaps some of the space time bending force but then when they are all criss crossing each other and compounding each other, that might create a more dense sort of space/time warping force that is propelling space time expansion.

    So, if the galaxies etc in the universe are expanding outward, from a single point in space(time), shouldn't astronomers have already detected that "more empty" central location in the universe? Where the density of stars, galaxies etc is much lower to practically nonexistent compared to other areas in the universe? Especially if the expansion is accelerating outward ever more? Or have we not been observing the universe long enough, and light takes so long to get to us, that we have no way to know what is actually going on in most areas in the universe right now? We only are able to read/view the past condition of the universe except for very, very close stars?

    As the universe expands due to the big bang, and the impact of gravity having formes a bubble, as the 'bubble' expands in all directions it seems like there is an increased rate in expansion; its actually caused by the increasing size that makes the increase seem to go faster, it is not.

    Images of the Universe shows a "web". I prefer to think of it as the living Universe's "venous" system. Not blood but the gases & chemicals of creating. The "expansion" is just the living Universe growing bigger … a natural thing that all living things do.

    If the calculations rely upon the speed of light being a constant, depending upon where you look, if it is NOT a constant, then it might not be expanding at all OR it might be expanding a lot.
