The End of Everything
You know all this isgoing to end, righté Like, you and your guineapig and the bacteria living in your bathtub andthe Real Housewives franchiseé All those things are going to end.And of course you know that. But also big, permanentseemingthings are going to end: like the earth, the Sun, this galaxy, that galaxy over there,and the universe! The end's not going to happensoon, but give it some time,
and even the universe willchange into something different something we wouldn't even recognize.And then POOF, gone. How exactly that's goingto happen is, of course, up for some serious debate,because what we don't know about the universe couldfill.like, a universe. But astrophysicists, cosmologists,and particle physicists are pretty smart people, and theythink about this all the time. So, at this point, what do theythink is going to happen to Earth,
the Solar System and the Universein the far distant futureé It's good stuff to know, you know. Just in case you happen to run outof other stuff to worry about. INTRO The Universe is about13.7 billion years old, give or take about130 million years, but it hasn't alwaysbeen the way it is now. It's believed that it wasborn with the Big Bang
as an unfathomably hot, densepoint called a singularity. The Big Bang didn't occur as anexplosion like you would think, even though it'scalled the Big Bang. And the universe didn'texpand into space, because space didn't existbefore the Universe was formed. Instead, think of the Big Bangas the simultaneous appearance of space everywhere in the universe. You know, if you can picture that.I, for one, cannot.
But the people who study thisstuff say that the universe hasn't expanded from anyone spot since the Big Bang, but that space itselfhas been stretching, and carrying matter with it. So, the Universe started ata single, hot, dense point smaller than an electron orsomething, and at the ripe old age of a hundredth of a billionth of a trillionth of atrillionth of a second,
this point began to expandfaster than the speed of light in a process called inflation. It's thought thatin the same instant, the universe doubled insize at least 90 times, growing from the sizeof a subatomic particle to the size of a golf ball,TADA! Whole universe! From there, it continued togrow a little more slowly, and as it expanded, it cooled,and matter began to form. Â
Yellowstone National Park from Above 7 Stunning Sights from Yellowstone Lake to Old Faithful HD
Our journey begins at the East Entrance ofYellowstone National Park, exploring the lake Yellowstone. We continue tracking Yellowstoneriver and catch our first glimpse of the parks' geothermal features in the Mud Volcano area. As we look north, we discover why the viewsof the Upper and Lower Falls had such a dramatic impact on the park's creation. Following the grand Canyon of Yellowstonewe head to the open plains of the Lamar valley. At the northwest corner of Wyoming, we understandwhy the park is a national treasure, starting with the Mammoth Hot Springs.
Venturing southward exploring the geothermalbasins of the Yellowstone crater, we arrive at its most famous feature, Old Faithful,in time for a spectacular finale to our journey. With five entrances to Yellowstone NationalPark, we approach from the East, following along the Shoshone River in the Wapiti Valleyabout eighty kilometres from Cody, Wyoming. Because of the weather restrictions, the EastEntrance to the Yellowstone Park remains open only from May to November. On entering the park, there's a glimpse ofthe towering peaks of the Absaroka Range of the Rocky Mountains.
Yellowstone, which became the world's firstnational park in 1872, hosts over three million visitors a year. Access to the park from the east is made possibleby the Sylvan Pass, maintained to allow winter travel by snowmobile or snow coach. It was named after Sylvan Lake which restsalong the route. As we continue along the pass, we come toYellowstone Lake, the largest body of water in the park. Its basin is part of the massiveYellowstone crater carved from volcanic eruptions over 600,000 years ago.
Yellowstone offers a splendid habitat forover sixty species of large mammals. Here we spot a small herd of elk. The parkhosts an estimated thirty thousand in total. The lake's northern tip is where it's fedand drained by Yellowstone River. A Fishing Bridge crosses at this meeting point a spawning area for t native cutthroat trout. And nearby, is a popular Recreational VehiclePark. Visitors wanting less rustic accommodationstay at the historic Lake Hotel. Originally built in the late 19th century,the hotel was restored to its 1920s grandeur
in 1990. The Yellowstone River is a main tributaryof the Missouri River and drains nearly an elevenhundred kilometre stretch of the Rockies. Within the park, the river is used recreationallyfor flatboat fishing. The words Yellow Stone were recorded by Lewisand Clark during their famous expedition, after meeting with the Minnetaree Indiansnear the river in 1805. North along the river, we enter the Mud VolcanoArea. These formations are created from a geoexcretionof iron and hydrogen sulphide, which results
in a dark gray colour and rottenegg smell. Flowing north out of Hayden Valley, the firstsigns of rapids are present as the Yellowstone River begins its descent toward the park'sGrand Canyon. The river first cascades at the Upper Falls,dropping about thirtythree metres. Spectacular viewing points along the trailson either side of the canyon make this one of the favourite places in the park amongvisitors. And it's yet another example of how Yellowstone'slandscape was shaped from volcanic events 600,000 years ago.
