Nasa puts up deep-space atomic clock

Nasa has put a miniaturized atomic clock in orbit that it believes can revolutionize deep-space navigation.
About the size of a toaster, the device is said to have 50 times the stability of existing space clocks, such as those flown in GPS satellites.
If the technology proves itself over the next year, Nasa will install the clock in future planetary probes.
The timepiece was one of 24 separate deployments from a Falcon Heavy rocket that launched from Florida on Tuesday.
The other passengers on the flight were largely also demonstrators. They included a small spacecraft to test a new type of "green" rocket fuel, and another platform that aims to propel itself via the pressure of sunlight caught in a large membrane; what's often called a "lightsail".

Our Universe Might Be Trapped Inside An Enormous Black Hole!

For almost a century, the Big Bang theory has been bandied as the ultimate theory that describes the origin of the universe. The universe, as we know by it, was created in a massive explosion that created the majority of the matter which our physical laws abide by. Scientists believe that our galaxy, the Milky Way, came into existence billions of years ago, following the Big Bang and that the already-vast universe is an ever-expanding cosmos.
Now, a recent breakthrough states that black holes also have the singularity trait in common with the universe. The new study conducted by a team of progressive astrophysicists at Canada’s University of Waterloo has mentioned that the universe exists farther from the horizon of a huge black hole with higher dimensions, and it might have been present in the cosmos right from the very beginning of time.
