Interstellar was right. Falling into a black hole is not the end, professor Stephen Hawking has claimed.
Although physicists had assumed that all matter must be destroyed by the huge gravitational forces of a black hole, Hawking told delegates in Sweden that it could escape and even pop into another dimension. The theory solves the ‘information paradox’ which has puzzled scientists for decades. While quantum mechanics says that nothing can ever be destroyed, general relativity says it must be.
However under Hawking’s new theory, anything that is sucked into a black hole is effectively trapped at the event horizon - the sphere surrounding the hole from which it was thought that nothing can escape. And he claims that anything which fell in could re-emerge back into our universe, or a parallel one, through Hawking radiation - protons which manage to escape from the black hole because of quantum fluctuations.
“If you feel you are in a black hole, don’t give up, there’s a way out,” Hawking told an audience held at the KTH Royal Institute of Technology in Stockholm In the film Interstellar, Cooper, played by Matthew McConaughey, plunges into the black hole Gargantura. As Cooper’s ship breaks apart in the force, he evacuates and ends up in a Tesseract – a four dimensional cube. He eventually makes it out of the black hole.

Why do we explore? Simply put, it is part of who we are, and it is something we have done throughout our history. In “We Are the Explorers,” we take a look at that tradition of reaching for things just beyond our grasp and how it is helping us lay the foundation for our greatest journeys ahead. So what are we doing to enable exploration? We’re building the Orion spacecraft is built to take humans farther than they’ve ever gone before. Orion will serve as the exploration vehicle that will carry the crew to space, provide emergency abort capability, sustain the crew during the space travel, and provide safe re-entry from deep space return velocities. Orion will launch on NASA’s new heavy-lift rocket, the Space Launch System.
Also underway, is Astronaut Scott Kelly’s Year In Space. Kelly is living and working off the Earth, for the Earth aboard the station for a yearlong mission. Traveling the world more than 220 miles above the Earth, and at 17,500 mph, he circumnavigates the globe more than a dozen times a day conducting research about how the body adapts and changes to living in space for a long duration.

For thousands of years, sea level has remained relatively stable. But now, Earth’s seas are rising. Since the beginning of the 20th century, they have risen about eight inches, and more than two inches in the last 20 years alone!
As water warms, it expands and takes up more space. That means that when oceans warm, the sea level rises. This summer, we’ve been researching exactly how global warming has impacted Greenland’s ice sheet. Our ICESat-2 mission will use a laser to measure the height of the planet’s surface. Over time, we will be able to provide a record of elevation change, and estimate how much water has melted into the ocean from land ice change.
So how much ice are we actually losing? Great question, but the answer might shock you. In Greenland alone, 303 gigatons of ice was lost in 2014!
Since we know that ice is melting, we’re working to gain a better understanding of how much and how fast. We’re using everything from planes, probes and boats, to satellites and lasers to determine the impact of global warming on the Earth’s ice.

Astronomy is important because it tells us how big is the universe and how it spreads even more and when we understand that infinite distances we will learn to love and appreciate what is closest to us
My astronomy teacher, Slobodan Spremo (via amsterdam-obsessed)
I love space. I've been to space camp in Huntsville Alabama and I am planning on going every summer. I look forward to be an astronaut for nasa on the sls that is planned to be launched 2018. And the manned mission 2030. So yeah I won't let anything get in my way.
