THE DARK UNIVERSE
Looking up in the sky we see stars shining the moon the sun and with the help of telescope we can see far far away stars and galaxies etc. The Universe is much more than the shining materials gases dust particle etc. Where light cannot penetrate how can we see such materials? Our Scientist Physicsts and




Astronomers have found that most of our Universe is Dark yet it is not empty. All the luminous matter in the Universe is only 4 to 5% rest is stark Dark.. known as Dark Matter and Dark Energy.
DARK MATTER:
At the moment of big bang dark matter was created and it played a critical role helping ordinary matter clump together and form stars and planets acted like scaffolding upon which ordinary matter could attach itself. dark matter was pulled together by gravity very slowly over time and actually form the scenes around which normal matter coalesced , like a cosmic web ,(a spiders web) where these strands of dark matter is the framework..
Astronomers have been able to take their theory one step further and create detailed 3d map of dark matter in the universe using gravitational lensing . Einstein said, the gravity affects everything just like gravity is caused by everything so one of the things that is affected by gravity is light itself .When light goes to the dark matter it bends just the way light bends when it goes thru the glass and light dosn’t discriminate ordinary matter and dark matter.

The missing mass in the galaxies during rotation speed of galaxies calculate by Fritz Zwhaky Jan Oort in 1930s and Vera Rubin in 1970s was termed as Dark Matter. Dark Matter hides in space…. acts as skeleton it is the backbone around which the visible material is clumping by…it is estimated dark martter makes up 24percent in the universe, well ordinary matter makes up only 4.6%. The final 71.4%percent of the universe Scientist were shocked to discover new mysterious dark energy was dominating space .It is driving the glaxies apart.
The prediction by the scientists that the Universe continues to grow in size..it will eventually slow expansion or perhaps even collapse on itself. But by measuring the expansion history of the Universe,Scientists were shocked to realize that the Universe was not slowing down it was speeding up…what mysterious force was acting for this vast speeding galaxies apart? ..The Dark Energy

The Dark Energy the mysterious force is created with the bursting of (white dwarf)dead star. … This Supernovae.or stellar explosion ,their brightness amounts to the Suns or a Stars radiation throughout its lifetime….
A lot of research is being done in particle physics on dark matter by the U.S. government. Projects like the Super Cryogenic Dark Matter Search (SuperCDMS), the LUX-ZEPLIN (LZ) Experiment, and the Axion Dark Matter Experiment Gen2 (ADMX-Gen2) have been initiated by the U.S. government for studying dark matter and its Weakly Interacting Massive Particles (WIMP)
