BLOG #2 - WHAT'S DARK ENERGY ?

Scientists have given the name dark energy to the expansion-generating force or substance of the universe. Dark energy is the reverse of gravity; it pushes things apart rather than pulling them together. It is unknown whether the laws of physics or the general theory of relativity can account for the dark energy. 
               In 1998, astronomers studying supernovae found them rather than anticipated. This meant both they were farther away and the universe was expanding faster than expected.
               The U.S. Government's Joint Dark Energy Mission (JDEM) examined Type 1a supernovae, dying white dwarfs,because of their high and consistent luminosity. The program ended in 2010 and was replaced by the Wide- Field Infrared Survey Telescope (W-FIRST) which was launched on 17 Feb 2016.

BLOG #1 - THE BIG BANG - COSMIC BEGINNINGS

Accepted astrophysical theories posit that at one point there was nothing: no stars, planets or galaxies - not even the space itself. The matter that makes up everything that now exists was concentrated in a single, extremely dense point known as a singularity. The force of gravity in a singularity is so great that the fabric of space time curves in on itself. In an instant known as the big bang, however, the contents of the primordial singularity escaped - and formed the universe.                The big bang is a catchy shorthand for a complex astrophysical theory, backed up with sophisticated calculations. The term was coined in the 1950s by British astronomer Fred Boyle, a proponent of a theory of the universe as a steady state. In fact, Boyle used the term derisively. Though the name stuck, it gives a false impression, making it seem as though the event that unleashed all the energy of the universe almost 14 billion years ago was an e...

Some Special(yet some common) Things to START BELIEVING in yourself AGAIN - PART 5

...to be continued. 13) Accept your emotions without judging them You all know what, you will agree to this. Emotions are very big players, both against and with us. Whenever we experience an uncomfortable feeling, such as sadness, fear or anger, our first instinct is to ignore it, reject it or push it away. And this fair enough, we don’t really want to walk around feeling emotional pain all the time. Emotions give us useful information about our lives. It’s understanding that you don’t need to “control” your emotions. They cannot do any damage to you.  This means allowing your emotions to just be without negatively judging them or trying to change them. 14) Get rid of these 5 toxic beliefs Your beliefs and thoughts shape the perspective of your life. The way you think, interpret and react to a situation depends on your beliefs that matter for you.  But if your beliefs aren’t accurate, they could be negatively affecting you. Here are some beliefs that may sabotage our life: i....

Questions that question YOU from YOU - PART 1

Sometimes we get too caught up in our every day lives that we tend to forget one of our most basic instincts as humans — to question. And our lives have indeed become so easy and so simple, that we never get curious anymore. Thanks to the tech, obviously. After all, we are i the 21st century. So, in this piece for you, I've got some questions to make you spark the plugs into your grey matter.(not the GRAY matter,  its the grey matter) Now what's the grey matter first ? Grey  matter  contains most of the brain's neuronal cell bodies. The grey  matter  includes regions of the brain involved in muscle control, and sensory perception such as seeing and hearing, memory, emotions, speech, decision making, and self-control. Enough for the intro, I guess. So, here are the questions. Q. Why do we all FEAR death ? Q. What is REALITY ? Q. Is our SOCIETY teaching us the WRONG things ? Q. Is TIME only a concept made by humans ? Is it something we RESTRICT ourselves with ? Q....
