TheNerd'S SpaceTime

Mysterious radio signals have dominated astronomy discoveries for quite a time now.  Astronomers have disclosed information on unusual signals coming from the center of our galaxy. A  team scanning radio waves in the Universe has uncovered something odd that emits a massive burst of energy three times each hour, unlike anything astronomers have ever seen. Spinning around in space, the odd object emits a beam of radiation that crosses our line of sight and is one of the brightest radio emitters in the sky for one minute out of every twenty. The actual nature and origin of the radio wave explosions are unclear. Scientists have discovered another odd radio emission originating from the core of our galaxy, which has yet to be explained. A radio source that was recently described in the paper and that does not seem to fit the patterns we've observed from other radio sources,  such as various neutron stars, various white dwarfs, or potentially black holes,  all o...

The biggest machine in the world is going to restart after three years of shutdown and upgrades. The Large Hadron Collider is the world's largest and highest-energy particle collider. It consists of a 27-kilometer-long ring of superconducting magnets where energetic particlesSmash into each other, leading to spectacular collisions and discoveries. Over the years, LHC has made some spectacular contributions to particle physics.It changed our understanding of the universe with the discovery of Higgs Boson in 2012 and paved the way for the discovery of more than 50 new particles. However, at the end of 2018, LHC was shut down for two years for further upgrades. Although the shutdown was planned for only two years, the ongoing pandemic delayed operations longer than expected. So what can we expect in the upcoming operations of the LHC? How will the biggest particle accelerator shape the future of particle physics? And most importantly, what will be this machine's most important sci...

When people say that Isaac Newton completely transformed the field of physics, they really aren't kidding.Another of Newton's famous contributions to physics was his understanding of gravity. When Newton was first starting, scientists' concept of gravity was pretty much nonexistent. I mean, they knew that when you dropped something, it fell to the ground, and from careful observation, they knew that planets and moons orbited in a particular way. What they didn't know was that those two concepts were connected. Of course, just like with motion, we now know that there's a lot more to gravity than what Newton could observe. Even so, regarding describing the effects of gravity on the scale of, say, our solar system, Newton's law of universal gravitation is incredibly useful. And it all started with an apple… Probably.  Odds are, you've been told the story of Newton's apple at some point. The story goes that one day, he was sitting under an apple tree in his ...

   Whenever we look up in the night sky, we sometimes wonder, what are those twinkling lights. The most basic answer is a star. And when we refer to a star, the "Sun" is the first name that comes to our mind. Stars are massive celestial objects, the creators of the world and its creatures. Everything we see around us is made up of atoms that derive from the cosmic kitchens of the stars. You, I, everything is made up of atoms that were formed inside the sun and other associated phenomena in other stars. Inside these kitchens, atoms of hydrogen are cooked into atoms of heavier elements. So, the cosmic story of a star goes like this-Stars are formed from condensed interstellar gas, i.e., hydrogen, and helium clouds that are present in between stars within a galaxy. These huge clouds of interstellar gas are called "nebulae", the singular "nebula". A protostar forming.   They undergo a gravitational collapse forming protostars, the first stage of a star. They u...
