Neutron stars are created when giant stars die in supernovae and their cores collapse, with the protons and electrons essentially melting into each other to form neutrons. Neutron stars are city-size stellar objects with a mass about 1.4 times that of the sun. Born from the explosive death of another, larger stars, these tiny objects… Continue reading What Is A Neutron Star?

What is Time?
Time is something that everyone is familiar with 60 seconds is one minute, 60 minutes is one hour, 24 hours is one day and so on. This is known as Linear Time and is something that everyone is familiar with and agrees upon. But consider this, if someone came up to you on the street… Continue reading What is Time?
Pulsed Plasma Thrusters
While travelling in space, one of the hardest things to do is to stop or change direction. Without anything to push against or friction to slow things down, spacecraft need to do all the hard work of changing their speed or path by there thrusters. And sometimes they do that in ways you would never… Continue reading Pulsed Plasma Thrusters
The Big Rip Due To Dark Energy
Even though nobody else will be around to see it, scientists are fascinated by the end of the universe. It is kind of like the Big Bang there’s just something so interesting about knowing where your atoms came from and where they are ultimately going to go in billions of years. Right now, there are a few ideas about how everything… Continue reading The Big Rip Due To Dark Energy
Let’s Understand Naked Singularities
When people talk about black holes, there is one thing that pretty much always comes up is that Black holes get their name because the infinitely tiny, infinitely dense point in the centre has a gravitational pull so strong that even light can’t escape. The thing is, that might not always be true. For the past half-century — basically,… Continue reading Let’s Understand Naked Singularities
Origins Of The Universe
The universe is everything from the tiniest particles to the largest galaxies to the very existence of space-time and life. But how did it all begin? The origin of the universe is the origin of everything. Multiple scientific theories plus creation myths from around the world have tried to explain its mysterious Genesis. However, the most widely accepted explanation is the Big Bang Theory.… Continue reading Origins Of The Universe
3 Biggest Experiments Ever
There are things in nature so huge or complex that the only way to really study them is to build something enormous. Like, physicists didn’t just find the Higgs boson by fishing it out from under the couch. It took the world’s largest machine, the Large Hadron Collider, to observe it. But when it comes to outright size,… Continue reading 3 Biggest Experiments Ever
Why Does Time Pass?
Why does time pass? It is a question so profound that few people would even think to ask it yet its effects are all around. Human beings live in a perpetual present inexorably sealed off from the past, but moving relentlessly into the future. For most people time seems to be something that is just out there, a… Continue reading Why Does Time Pass?
Role Of The Plasmoid Instability In Magnetohydrodynamic Turbulence
The sun defies conventional scientific understanding. Its upper atmosphere, known as the corona, is many millions of degrees hotter than its surface. Astrophysicists are keen to learn why the corona is so hot, and scientists at the U.S. Department of Energy’s (DOE) Princeton Plasma Physics Laboratory (PPPL) have completed research that may advance the search.… Continue reading Role Of The Plasmoid Instability In Magnetohydrodynamic Turbulence
Vision-Based High Speed Driving With A Deep Dynamic Observer Combining Convolutional Neural Networks And Model Predictive Control
Researchers at the Institute for Robotics and Intelligent Machines (IRIM) of the Georgia Institute of Technology have recently proposed a new framework for aggressive driving using only a monocular camera, IMU sensors and wheel speed sensors. Their approach, presented in a paper pre-published on arXiv, combines deep learning-based road detection, particle filters and model predictive… Continue reading Vision-Based High Speed Driving With A Deep Dynamic Observer Combining Convolutional Neural Networks And Model Predictive Control
How Does Exercise Treatment Compare With Anti-Hypertensive Medications?
Exercise may be as effective as prescribed drugs to lower high (140 mm Hg) blood pressure, suggests a pooled analysis of the available data, in what is thought to be the first study of its kind, and published online in the British Journal of Sports Medicine. But there is no direct head to head comparative… Continue reading How Does Exercise Treatment Compare With Anti-Hypertensive Medications?
More Gravitational Waves Have Been Detected
Scientists have identified four more ghostly signals of massive collisions in outer space, including of the largest to date, bringing their total haul of gravitational-wave detections to 11 in just a few years. And even better, that wealth of observations is large enough to let scientists make broader discoveries about the world around us and… Continue reading More Gravitational Waves Have Been Detected
The Universe’s Continued Existence Suggest That Extra Dimensions Are Tiny
If extra dimensions were large enough, a universe with different laws of physics could bubble up from the death of a black hole. That would be bad news for us: The new version would be uninhabitable. This could be the way the world ends. First, a pair of cosmic protons smashes together at unimaginable speeds.… Continue reading The Universe’s Continued Existence Suggest That Extra Dimensions Are Tiny
How Will The Universe End?
While it may seem as if the universe will go on forever it more than likely has an expiration date. Luckily you won’t have to worry about it and neither will your grandkids. Estimates on when the end of all things will actually occur range from 100 trillion to just 2.8 billion years away. In… Continue reading How Will The Universe End?
