Is the Universe Getting Bigger?
The universe is continuously expanding, a phenomenon observed by astronomers through the redshift of distant galaxies. While galaxies remain bound by gravity, the space between them stretches, a process accelerated by dark energy.
Why it matters
Understanding the expansion of the universe is fundamental to cosmology and our comprehension of the origins and future of existence.
Is the Universe Getting Bigger? The universe is bigger now than it was when you started reading this sentence. Every distant galaxy is drifting away from us as the space between them stretches. Astronomers spotted this a century ago in the reddened light of far-off galaxies. They still argue over exactly how fast that stretching happens. Dark energy seems to be pushing the whole process faster every year. Where it all leads remains the strangest open question in cosmology.
