Answer
The Big Bang Theory says that all atomic particles were highly compressed together and then exploded outward about 13 billion years ago. Particles clumped together after the explosion to form atoms and then later stars and galaxies.
See Big Bang Theory

Question

Hello.....
I love learning from your site.
Can you give me some other FREE websites from where I can gain knowledge about astronomy?
And PLEASE, don't think that your website is not enough for me.
I just love your website!
Priyam - India

Answer
Sky and Telescope Magazine has a good list of astronomy websites.
NASA Science has much about space science.
Astronomy Magazine has some interesting articles about the latest in the subject.
Orbit page missing
Topic: General
Question
October 19, 2011
A course website I help maintain was linking to a page on your website but the link now returns a page not found message. The page was at your school for champions domain followed by the path:
science/orbit1.htm
Has the material moved? In particular our website referred to a demonstration of a satellite revolving around the Earth. If you would let me know where that moved I would appreciate it.
Linda - USA

Answer
If I remember, that was a simulation of a satellite in orbit as a Java app. The page was from about 2005. But unfortunately, the application was not working as it should, so I removed it.
Usually, I provide a link to a page that has been moved and keep that link available for a few years.
If such an animation of an object in orbit is of interest to you and your students, I might be able to add something like that to the site. Let me know.
Sorry about the inconvenience.
What heavenly bodies can I see from Ahmedabad?
Topic: General
Question
October 11, 2011
I want to explore more and more
What all heavenly bodies can I see from Ahmadabad, Gujarat, in India?
Priyam - India
22059
Answer
You should be able to see most of the galaxies and constellations in the Northern Hemisphere, as well as some of those in the Southern Hemisphere from Ahmadabad.
However, many cities have what is called "light pollution" where the city lights and humidity in the air block out the view of many stars. Observing the sky from away from the cities and even in the mountains is the best way to get a good view of all the stars.
What are the constellations seen from India?
Topic: General
Question
October 10, 2011
Which all constellations can we see from India?
Priyam - India

I hope that helps.

How can radiation escape a Black Hole?
Topic: General Topics
Question
June 18, 2011
if black hole has a high gravity and attracts even light, then how can radiations known as black hole radiations can get out from there?
Shourya - India
21733
Answer
Although a Black Body has such high gravity that particles or even light inside cannot escape, they still give off some radiation calling Hawking Radiation.
A Black Hole can have energy fluctuations, which cause the generation of particle-antiparticle pairs near the event horizon of the Black Hole. The event horizon is the edge where particles inside cannot escape, but particles outside the event horizon can escape.
If the particle-antiparticle pair is right at the event horizon, one of the particles falls into the Black Hole while the other escapes before they have an opportunity to annihilate each other.
It is s surprising phenomenon.
