How the Universe Will End
Ultimately, space could collapse back in on itself, destroying all stars and galaxies in existence, or it could expand into essentially an endless void.
What's the Latest Development?
Based on currently observable data, scientists agree that the universe will end in one of three ways: The Big Freeze, the Big Rip or the Big Crunch. All scenarios depend on the behavior of dark energy, that mysterious force which is counteracting the pull of gravity, causing the universe to expand rather than contract. If dark energy remains stable, galaxies will spread further and further apart. If dark energy increases in intensity, the universe will expand at an ever inreasing rate, destroying entire galaxies.
What's the Big Idea?
Thanks to its revolutionary implications, the discovery of dark energy was awarded the 2011 Nobel Prize in physics. Previously, scientists believed that the force of gravity—the attraction of matter to other matter relative to mass—would cause the universe to contract, bringing all matter back to where it began "before" the big bang. That scenario is the Big Crunch. Within the next decade, scientists expect to be able to measure the rate of the universe's expansion at distances far from our galaxy, shining light on the true nature of dark energy.
Orangutans join humans and bees in a very exclusive club
- Orangutan mothers wait to sound a danger alarm to avoid tipping off predators to their location
- It took a couple of researchers crawling around the Sumatran jungle to discover the phenomenon
- This ability may come from a common ancestor
In a breakthrough for nuclear fusion research, scientists at China's Experimental Advanced Superconducting Tokamak (EAST) reactor have produced temperatures necessary for nuclear fusion on Earth.
- The EAST reactor was able to heat hydrogen to temperatures exceeding 100 million degrees Celsius.
- Nuclear fusion could someday provide the planet with a virtually limitless supply of clean energy.
- Still, scientists have many other obstacles to pass before fusion technology becomes a viable energy source.
Journaling can help you materialize your ambitions.
- Organizing your thoughts can help you plan and achieve goals that might otherwise seen unobtainable.
- The Bullet Journal method, in particular, can reduce clutter in your life by helping you visualize your future.
- One way to view your journal might be less of a narrative and more of a timeline of decisions.
