Researchers confirm the universe is expanding uniformlyEditage Insights
The Steady-State model states that the density of matter in the expanding universe remains unchanged over time because of the continuous creation of matter. In other words, the observable Universe essentially remains the same regardless of time or place. This places it in sharp contrast to the t...
It doesn't suppose what the universe is expanding into. It doesn't even explain what caused the expansion in the first place. And there are reasons why trying to imagine the event as an explosion can lead to some misinformed conclusions. ...
The universe is expanding, but instead of slowing down, like most physics examples would predict, it is accelerating. Learn how dark energy appears in different forms, and understand the implications of dark energy on the expansion of the universe. ...
FALSE:In some of Tenney’s cases, certain residents of “haunted” houses have reported weird noses that Tenney attributes to a change in temperature. He explained that wood, steel and other materials shrinking or expanding might be causing that bump in the night, especially during the fall and...
In 1917, Einstein idealized the universe as a 3-sphere uniformly filled with matter. The result of this calculation was that the radius of such a 3-sphere increases with time (Nussbaumer2014). This was a momentous discovery, as the equations predicted the expansion of the universe. There, in...
Why is dark energy a necessary part of the universe? About 25 years ago, it was established that the Universe is expanding, and such expansion is speeding up with time. This process has been occurring for the last 5,000 million years, and it causes galaxies to recede from others. Although...
The cosmic microwave background (CMB) is leftover radiation from theBig Bangor the time when the universe began. As the theory goes, when the universe was born it underwent rapid inflation, expansion and cooling. (The universe is still expanding today, andthe expansion rate appears different de...
Apple debuted its capacitive multitouch iPhone in a world full of keypads and slide out keyboards that tech critics were lathered up about, but which soon vanished from the market because critics were uniformly wrong about what customers would want. ...
