Since the Universe burst into existence an estimated 13.8 billion years ago, it has been expanding outwards ever since. But because we don't know a precise age for …Pursuit of the universe's expansion rate began in the 1920s with measurements by astronomers Edwin P. Hubble and Georges Lemaître. In 1998, this led to the discovery of "dark energy," a mysterious repulsive force accelerating the universe's expansion.In recent years, thanks to data from Hubble and other telescopes, …The rate at which the universe is expanding, known as the Hubble constant, is one of the fundamental parameters for understanding the evolution and ultimate fate of …Maybe. Maybe not. A few decades ago, astronomers thought that the Universe was expanding because of momentum left over from the Big Bang. But with the discovery of dark energy in 1998, astronomers ...It is not difficult to see how the interpretation of Hubble’s law as cosmic expansion comes about. For a simple heuristic model, consider a hypothetical two-dimensional universe confined to the surface of a sphere2 of radius ρ. The 2-dimensional universe is certainly curved – in fact, it is a closed universe. A line (great circle – beam ...This has led astrophysicists to explore other avenues for explaining why the universe’s expansion is accelerating.

In that case the expansion will be infinite and forever. But another option is that the role of dark energy will lessen over time, causing the accelerated expansion to stop and transition smoothly into a slow contraction. This possibility dovetails neatly with the idea that the universe is continually expanding and contracting in an ongoing cycle.A prominent theory is that the universe will keep expanding, matter will become less dense as a result and soon all matter will just disintegrate in what is called the heat death of the universe ...What does it mean when they say the universe is expanding?

Einstein believed that the Universe was an infinitely large, all-encompassing blimp. This has led astrophysicists to explore other avenues for explaining why the universe’s expansion is accelerating. A new paper published in December of 2023 suggests a novel idea that our ...The expansion or contraction of the universe depends on its content and past history. With enough matter, the expansion will slow or even become a contraction. On the other hand, dark energy drives the universe towards increasing rates of expansion.
