What is time travel through a Wormhole
so we can say that when a liquid,gaseous,solid object gains circular velocity
we know the process of fussion of any cellestial objects. they are attracted by the gravity then they move circular to each other then they move away. this process continues till they collapse on each other. galaxies are enormous. if in future such thing is ought to happen because of configuration of universe. so a passage may form which can take us to some new

about my sir--
I met thombre sir in my school.It was an off period and he came to my class and started to tell information about the Black holes.Just before two days i had watched a science programme on black holes on discovery channel so i knew something about it. we discussed a lot.Since then we have constant discussion on phone,email or in school about various concepts.He taught me how to see the other side of science and how to understand the science. Everyday of school,before 15 minutes to the recess over bell,we talk with each other.He helped me in getting the first prize at the District level Debate competition. He is currently doing Ph.dHe is a Gold medalist in physics and teaches computer science in my school.I thank him for all the things and dedicate this 50th post to him...The persons who inspired me--Albert Einstein and Stephen hawkings.I always wonder how intelligent einstein would have been as he introduced a theory :relativity" which earlier only few people understood.
I DEDICATE THIS ARTICLE TO THOMBRE SIR,STEPHEN HAWKING AND ALBERT EINSTEIN.....

Why will not pluto and neptune collide
pluto, which is only about two-thirds the size of our moon, is a cold, dark and frozen place. Relatively little is known about this tiny planet with the strange orbit. Its composition is presumed to be rock and ice, with a thin atmosphere of nitrogen, carbon monoxide and methane. The Hubble Space Telescope has produced only fuzzy images (above) of the distant object.
Pluto's orbit
Pluto's 248-year orbit is off-center in relation to the sun, which causes the planet to cross the orbital path of Neptune. From 1979 until early 1999, Pluto had been the eighth planet from the sun. Then, on February 11, 1999, it crossed Neptune's path and once again became the solar system's most distant planet. It will remain the ninth planet for 228 years.
Pluto's orbit is inclined, or tilted, 17.1 degrees from the ecliptic -- the plane that Earth orbits in. Except for Mercury's inclination of 7 degrees, all the other planets orbit more closely to the ecliptic.
Interestingly, a similar thing happens with Jupiter's moons: Many orbit on the ecliptic, but some are inclined from that plane.
Did you wonder: Will Pluto and Neptune ever collide? They won't, because their orbits are so different. Pluto intersects the solar system's ecliptic, or orbital plane, twice as its orbit brings it "above," then "below" that plane where most of the other planets' revolve -- including Neptune. And, though they are neighbors Pluto and Neptune are always more than a billion miles apart.
Is it a planet at all?
Some astronomers think Pluto may have wandered into the system of planets from a more distant region known as the Kuiper belt -- a region beyond the orbit of Pluto thought to contain Pluto-like objects and comets that orbit the sun in a plane similar to the planets of the solar system.
If that's the case, Pluto is not a planet at all, but is probably more like a large asteroid or comet. Some have also suggested that it may have once been a moon of Neptune and escaped.
The International Astronomical Union, the organization responsible for classifying planets, gives these reasons for questioning Pluto's status as a planet:
- All the other planets in the outer solar system are gaseous, giant planets whereas Pluto is a small solid object
- Pluto is smaller than any other planet by more than a factor of 2.
- Pluto's orbit is by far the most inclined with respect to the plane of the solar system, and also the most eccentric, with only the eccentricity of Mercury's orbit even coming close
- Pluto's orbit is the only planetary orbit which crosses that of another planet (during 1999 Pluto will again cross Neptune's orbit, thus regaining its status as the most distant planet)
- Pluto's satellite, Charon, is larger in proportion to its planet than any other satellite in the solar system.
Pluto has one moon, Charon, which was discovered in 1978. The satellite may be a chunk that broke off Pluto in a collision with another large object.
Pluto Data (averages):
Diameter: 1,430 miles (2,301 kilometers)
Time to rotate: 6 days, 9 hours
Orbit: 248 Earth years
Compared to Earth:
Mass: 0.2% of Earth's
Diameter: 18% of Earth's
Distance from sun: 39 times as far
PLUTO: HADES IN ANCIENT MYTH, ROMAN GOD OF THE UNDERWORLD
Pluto was not discovered until 1930, by amateur American astronomer Clyde Tombaugh. Since Tombaugh's death in 1997, many astronomers have increasingly urged the International Astronomical Union, which names celestial objects, to strip Pluto of its status as a planet.

Crepuscular rays
pratap nagar
nagpur.
28th april 09
article 2--
series.. SCIENCE IN OUR DAILY LIFE!
Dear all,
Today i am talking about rays.. as we know the part of light that come from sun,we call it rays..
but there are two types of rays..
crepuscular rays and anti crepuscular rays..
as rays appear to be coming from the sky thus passing through clouds. so reflection and scattering of light is an important
phenomena.as we know that light has to pass through various layers of atmosphere, defraction of light takes place.. so the light from the stars reach our eye and the stars appear to be twinkling. similarly the light of sun also defracts before it reaches our eyes.. scattering of light enables the light to spread everywhere in world..
you must have seen on cloudy days.. the rays from sun come from behind the clouds.. so we can see that the light comes from a single point. these rays are called crepuscular rays. the rays which appear to come from a single point are known as crepuscular rays.we find that they are almost parallel after some distance from the cloud. but it is apparent like that in case of convex mirror.in this case all the light appears to come from a single point.
Crepuscular rays are usually red or yellow in appearance because the path through the atmosphere at sunrise and sunset pass through up to 40 times as much air as rays from a high midday sun. Particles in the air scatter short wavelength light (blue and green) through Raleigh scattering much more strongly than longer wavelength yellow and red light.
similar origination is of the anticrepuscular rays but they appear in the opposite direction in the sky.i mean they r in the opposite direction to sun.. but as we know that the earth and its surrounding atmosphere is curved, the crepuscular rays travel all the way from one's sunrise and sunset point in the horizon.but their projections are in curvature and they are visible only at the sunrise or sunset points of the horizon.. so we see them coming from the opposite direction.Crepuscular rays are usually much brighter than anticrepuscular rays. This is because for crepuscular rays, seen on the same side of the sky as the sun, the atmospheric light scattering and making them visible is taking place at small angles
Although anticrepuscular rays appear to converge onto a point opposite the sun, the convergence is actually an illusion. The rays are in fact parallel, and the apparent convergence is to the vanishing point at infinity.the reason is the curvature of the earth;s surface.
LIKE YOU ARE STANDING ON A BEACH.IT IS CLEAR SUNNY DAY AND A SHIP IS APPROACHING FROM INFINITY. SO AS THE SURFACE IS CURVED,WE WILL SEE THE FIRST DECK OF SHIP FIRST AND THEN LATER WE WILL SEE THE ENTIRE SHIP.. WE CAN SEE SOME PART OF SHIP'S DECK FOR THE FIRST TIME WHEN THE SHIP JUST CROSSES THE FIELD LIMIT THAT IS 180 DEGREE FROM US IN THE ENTIRE SKY AND THE SURFACE..
THIS IS TWO TYPES OF RAYS.NEXT TIME WHEN YOU GET UP IN THE MORNING OR WHEN YOU ARE SEEING A SUNSET..DO REMEMBER IT.

The forgotten Hero!!
- The object must be in orbit around the sun
- The object must be massive enough to be a sphere by its own gravitational force. More specifically, its own gravity should pull it into a shape of hydrostatic equilibrium.
- It must have cleared the neighbourhood around its orbit

EARTHQUAKE PREDICTION BETWEEN 18TH AUGUST TO 10 SEPTEMBER 09


earthquake striking place provided in the attachment on 2nd september
09
but we give the disaster window between 26st august to 10th september 09
some observations observed by us will help u to understand this
concept.the concept behind it remains the same about gravitational
pull.
1] SOLAR ECLIPSE OBSERVED ON 8TH JUNE 1937.IT WAS A TOTAL SOLAR
ECLIPSE FOR 7 MIN 4 SECONDS.
LUNAR ECLIPSE WAS OBSERVED ON 25TH MAY 1937 FOR A PERIOD OF 110 MINUTES
THE RESULTANT EARTHQUAKE TOOK PLACE ON JULY 22 1937 AND WAS OF
MAGNITUDE 7.3 ON RICHTER SCALE.
IT TOOK PLACE AT SALCHA,ALASKA USA..
THE DIFFERNCE BETWEEN THESE TWO DAYS
IS OF 15 DAYS.
2] SOLAR ECLIPSE OBSERVED --
11TH JULY 1991 for 6 min 53 seconds .
there was a total solar eclipse observed.
LUNAR ECLIPSE OBSERVED
JUNE 27TH 1991 FOR 110 MINUTES
THE DIFFERENCE BETWEEN THESE TWO DATES IS 15 DAYS
IT IS THE PERIOD TAKEN BY MOON TO GO FROM DARK SIDE INTO LIGHT SIDE.
EARTHQUAKE TOOK PLACE ON 17TH AUGUST 1991 AT HONEYDEW,CAIF,USA
MAGNITUDE OF EARTHQUAKE---------- 7.1 ON RICHTER SCALE..
FROM THE ABOVE OBSERVATIONS,THE DIFFERENCE BETWEEN EARTHQUAKE DATE
AND SOLAR ECLIPSE IS 37 DAYS AND 46 DAYS RESPECTIVELY.
THESE ARE SPECIAL OBSERVATIONS FOR A TOTAL SOLAR ECLIPSE AND
PENUMBRAL LUNAR ECLIPSE WITH NODE- A.
THE MEAN PERIOD FOR THIS IS 42 DAYS.
FOR THIS YEAR LUNAR ECLIPSE
AND SOLAR ECLIPSE
SO, ACCORDING TO THE STUDY OF THE ABOVE OBSERVATIONS, THE RESULTANT
EARTHQUAKE,WILL BE ON 2nd SEPTEMBER 09 AND OF MAGNITUDE 7.0+ ON
RICHTER SCALE
LOCATION OF THIS EARTHQUAKE REMAINS SAME...
CHANCES OF TSUNAMI WAVES ORIGINATING FROM THE PACIFIC ARE THERE.........
