tell me about universe??

Answer 1

The Universe is a huge wide-open space that holds everything from the smallest particle to the biggest galaxy. No one knows just how big the Universe is. Astronomers try to measure it all the time. They use a special instrument called a spectroscope to tell whether an object is moving away from Earth or toward Earth. Based on the information from this instrument, scientists have learned that the Universe is still growing outward in every direction.

Scientists believe that about 13.7 billion years ago, a powerful explosion called the Big Bang happened. This powerful explosion set the Universe into motion and this motion continues today. Scientists are not yet sure if the motion will stop, change direction, or keep going forever.

Answer 2

Universe has a variety of meanings, based on the context in which it is used. In strictly physical terms, the total universe is the summation of all matter that exists and the space in which all events occur or could occur. The part of the universe that can be seen or otherwise observed to have occurred is usually called the known universe, observable universe, or visible universe. Because cosmic inflation removes vast parts of the total universe from our observable horizon, most cosmologists accept that it is impossible to observe the whole continuum and may use the expression our universe, referring to only that which is knowable by human beings in particular. In cosmological terms, the universe is thought to be a finite or infinite space-time continuum in which all matter and energy exist. Some scientists hypothesize that the universe may be part of a system of many other universes, known as the multiverse.

Ahem...
Whenever life get you down, Mrs. Brown
And things seem hard or tough
And people are stupid, obnoxious or daft
And you feel that you've had quite enooooouuuuugggghhhhhh...
Just remember that you're standing on a planet that's evolving
Revolving at 900 miles an hour
It's orbiting at 19 miles a second, so it's reckoned
A sun that is the source of all our power
The sun and you and me, and all the stars that we can see
Are moving at a million miles a day
In an outer spiral arm, at 40,000 miles an hour
Of the galaxy we call the Milky Way
Our galaxy itself contains 100 billion stars
It's 100,000 light-years side-to-side
It bulges in the middle, 16,000 light-years thick
But out by us it's just 3000 light-years wide
We're 30,000 light-years from galactic central point
We go round every 200 million years
And our galaxy is only one of millions of billions
In this amazing and expanding universe
The universe itself keeps on expanding and expanding
In all of the directions it can whiz
As fast as it can go, at the speed of light you know
Twelve million miles a minute and that's the fastest speed there is
So remember, when you're feeling very small and insecure
How amazingly unlikely is your birth
And pray that there's intelligent life somewhere up in space
Because there's bugger all down here on Earth

Answer 4

Watch "Naked Science" on National Geographic Channel. It has the best explanation of the beginnings of the universe.

Answer 5

Sizewise: your house is about 1000 sq feet
The earth is about 40000 feet in diameter.
The earth is 150 billion metres away from the sun.
There are ten billion stars in a galaxy seperated by 50 million million kilometres.
There are ten billion such galaxies in the universe.

Not enough room here

Answer 8

It's really, *really*, **REALLY* big. Ginormous, in fact. And it holds everything (which is why it has to be so big)
