Answer. When scientists talk about the expanding universe, they mean that it has been growing ever since its beginning with the Big Bang. Galaxy NGC 1512 in …Then the question raised "WHY IS THE UNIVERSE EXPANDING?". There are a few interesting concepts that answer this question. THE DARK MATTER-The dark matter or dark energy which had been radiated after the big bang theory is supposed to be the main reason causing the expansion of the universe. Also on a daily basis, there are a lot of radiations ...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 the cosmos. However, a persistentRedshift is an important tool for cosmology, because it indicates that the Universe is expanding. Astronomer Edwin Hubble using the 100-inch Hooker reflector at the Mount Wilson Observatory, was the first to discover that virtually all galaxies show redshifts in their spectra. Initially the cause of the redshifts in the spectra of galaxies was ...An extra dose of dark energy in the early universe, dubbed early dark energy, could reconcile the conflicting values of the Hubble constant. The outward pressure of this early dark energy would have sped up the universe’s expansion. “The tricky part is that [early dark energy] can’t really stick around; it has to go away quickly,” said ...
Explanation: The universe is thought to be expanding by: The initial "explosion" (not an explosion but a rapid expansion) produced so much energy the space-time frame expands with greater acceleration, the microwave cosmic radiation energy generated by the Big Bang. Dark energy (theory) Answer link. Because of …In short, the universe isn’t expanding into anything. It is just getting larger. This misconception stems from the assumption that there must be something outside of the universe to expand into. Given that the universe normally is defined as the totality of physical existence, then there cannot be anything physical …

Since then, gravity and dark energy have engaged in a cosmic tug of war. Gravity pulls galaxies closer together; dark energy pushes them apart. Whether the universe is expanding or contracting depends on which force dominates, gravity or dark energy. Here's the short answer: That question doesn't make sense. The universe is everything, so it isn't expanding into anything. It's just expanding. All of the galaxies in …The expansion of the universe is getting out of hand.

Perhaps the most astonishing and revolutionary discovery in cosmology was Edwin Hubble's observation that galaxies are moving away from us. It provides the underpinning of the big bang picture of creation in which the universe is expanding, and has been for 13.7 billion years. But astronomers in the last century were ...Jun 30, 2010 · Hubble analysed how galaxies recede from the Milky Way.

One intriguing reason could be that dark energy – the mysterious force that seems to be driving acceleration of the expansion of the universe – is itself not uniform. In other words, the X-rays may reveal that dark energy is stronger in some parts of the universe than others, causing different expansion rates.Jun 2, 2016 ... The discrepancy — the universe is now expanding 9 percent faster than expected — means either that measurements of the cosmic microwave ...

When scientists talk about the expanding universe, they mean that it has been growing ever since its beginning with the Big Bang. Galaxy NGC 1512 in Visible Light . Photo taken by the Hubble Space Telescope. The galaxies outside of our own are moving away from us, and the ones that are farthest away are moving the fastest. 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. The current rate of expansion is usually expressed as the …- ciaran mccormick "If the universe is expanding, and galaxies are moving farther apart, then why is it that the Milky way and Andromeda galaxies are on a collision course?"The rapid expansion of the early universe — The universe started out small.
