BIG BANG BEFORE BIG BANG
98th Article,
""I have idea that were there were bigbangs before the big bang which we know.As dark energy is supposed to accelerate the rate of expansion of universe, was it so that after some years the universe will begin to contract and will get coverted into a form of 1 big body which will have the nature opposite to the body from which we all were born. Thus i mean that is it so that after x yrs universe contracts.then it gets fully contracted into a giant mass body. the body then begins to expand because of some tendancy and then again explodes.""
It was just my thought during the science conference in my school. but when it was verified by Dr. Apte,Ph.d Physics, I felt happy
Actual thing is that currently the universe is in the state of expansion, the rate is being accelerated by dark energy. which constitutes about 73% of our universe. After some years 80 billion years there will be another big bang and again universe will be formed. It will happen as follow--
Universe will expand with increasing rate. After 40 billion years,The effect of dark energy will be maximum and after that time,
that is just after a second dark energy will no more act on us and then the gravitational force will be the strongest one, so you will be having a collapse after another 40 billion years from that period. Once the entire matter is concentrated, it will again explode. Thus this is alternate expansion and contraction of universe. This can be slightly compared to Moon Miranda.
REMEMBER IT CANT BE ENTIRELY COMPARED WITH MIRANDA.
The main question is where will the dark energy go?
i have an answer,Dark energy will be converted to other forms of energy. At the last stage it will be zero and everything will be converted in other energy. Currently Dark energy is stronger than gravitational force.

What is the moon impact of LCROSS

WHATS THE IMPACT ON MOON!
DEAR ALL
A happy moment for we space lovers as i finally got to see a LIVE LUNAR DESCENT. Many of you must have seen Neil Amstrong's descent. But i didn't see it
Whats LRO/LCROSS?
LRO is a spacecraft of nasa
IT'S MAIN PURPOSE IS TO MAP THE MOON!
LCROSS IS A SPACECRAFT THAT IMACTED THE MOON.
The LCROSS mission is a search for water on the moon. The LCROSS mission is going to do this by sending a rocket crashing into the moon causing a big impact and creating a crater, throwing tons of debris and potentially water ice and vapor above the lunar surface. This impact will release materials from the lunar surface that will be analyzed for the presence of hydrated minerals which would tell researchers if water is there or not. The two main components of the LCROSS mission are the Shepherding Spacecraft (S-S/C) and the Centaur upper stage rocket. The Shepherding Spacecraft guides the rocket to a site selected on the moon that has a high probability of containing water. Because they have only one chance with this mission in finding water, the researchers have to be very precise where they program the Shepherding Spacecraft to guide the rocket.
The Shepherding Spacecraft and Centaur rocket are launched together with another spacecraft called the Lunar Reconnaissance Orbiter (LRO). All three are connected to each other for launch, but then the LRO separates one hour after launch. The Shepherding Spacecraft guides the Centaur rocket through multiple Earth orbits, each taking about 38 days. The rocket then separates from the Shepherding Spacecraft and impacts the Moon at more than twice the speed of a bullet, causing an impact that results in a big plume or cloud of lunar debris, and possibly water. While this is happening the Shepherding Spacecraft, which has scientific instruments on-board including cameras, is taking pictures of the rocket’s descent and impact into the moon. Four minutes later, the Shepherding Spacecraft follows almost the exact same path as the rocket, descending down through the big plume and analyzing it with special instruments. The analysis is specifically looking for water (ice and vapor), hydrocarbons and hydrated materials. The Shepherding Spacecraft is collecting data continuously and transmitting it back to Earth before its own demise. This crash will be so big that we on Earth may be able to view the resulting plume of material it ejects with a good amateur telescope.
SO IN SHORT A COSMIC DRILL WHICH IMPACTED THE MOON. LIKE IT TAKES PLACE IN MINING. THE SURFACE ON MOON RISES HIGH IN SPACE DUE TO EXPLOSION. ANOTHER SPACECRAFT SHEPHERDING SPACECRAFT FOLLOWS IT AND TAKES IMAGES,DATAS AND RELAYS BACK TO EARTH.
I MUST SAY,WONDERFUL IDEA.
ALL THE EVENTS WHICH WERE PLANNED BY NASA TOOK PLACE SUCCESSFULLY. LCROSS IMPACTED THE MOON ABOUT 7 MINS LATE IN THE SHADOW REGION OF CABEUS REGION
WHY WAS CABEUS ONLY SELECTED?
Cabeus is a crater which is in the southern polar region of the moon about 100 kms away from South Pole. Cabeus appears slant from the earth and most of it remains in darkenss. due to this to potential for water/ice
That's why it was decided to impact this crater
I SENT MY and my father's NAME ABOARD THE ORBITER AND NOW WE HAVE OUR NAME ON THE MOON..
WITH JOY
