Also if you know what is earth’s place in the galaxy and our galaxy’s place in the universe.

Speed is measured relative to a stationary object. Velocity is determined by calculating the time it takes to travel a known distance from a stationary object. A cars speedometer measures speed relative to the stationary ground it is traveling on. An airplane measures speed by the same thing, by how long it takes to travel between points of a known distance on the ground.

So when it is said that a spacecraft is hurtling at 46,000 miles per hour beyond the orbit of Pluto towards the next star, what is that speed being compared against? In that part of space, there is no stationary object to calculate velocity. Is it still being compared to a stationary object on the surface of the Earth? At that distance, the Earth is traveling through space in orbit around the sun, which is traveling in orbit around the galaxy, which is traveling through space around who knows what.

So, what is the spacecraft traveling at 46,000 miles per hour from or towards that can be measured?

All the TV shows about characters that live or come from space such as the transformers, the TV show V or various other animated spots have kids wondering something. That would be wondering to know where all these characters come from.

The answer is up in space from another galaxy. At least that is what they think. The younger they are the more they believe that Optimus Prime out there somewhere just waiting to come down and save the earth the earth from the decepticons. An imagination is a good thing to have.

How can you use this interest to get kids interested in the stars?

Get them a telescope. A telescope will allow them to see craters on the moon, distant stars, the rings around saturn and much more. Just be sure they do not use it to look into the neighbors house down the street.

While looking at the stars with your child, you can suggest that maybe the transformers are living in a crater in the moon. You can find the name of that crater and your child will probably never forget where it is or the name. You can ask questions while the child is looking through the telescope. You can ask where they think the decepticons live. When they pick out a place, that celestial body will be in their memory for a lifetime. It will give them something to tell their kids.

To further advance this interest in space you will need a good telescope. Do not go and buy a toy telescope from a toy store. They are just that, toys. They will not allow you to get the full experience of star gazing either.

One of the great discoveries in astronomy during the twentieth century was that
A) there used to be life on Mars.
B) at the largest scale, galaxies are randomly distributed in space.
C) our star, the Sun, is located outside of the Milky Way.
D) our galaxy is alone amongst the other galaxies; it is not part of a cluster of galaxies.
E) our galaxy is only one of many billions in the universe.

Are there anything (unknown celestial bodies or something else) in the space between each galaxies in clusters of galaxy?

They are not void (voids are the empty space between each super clusters in universe?)?

edit:
What is in the empty space of Local Group?

The Mayan calendar ends on Dec. 21, 2012. They predicted that when the calendar ends the earth will change. This date coincides with the astronimical event when the earth will be in line with the sun and the center of our galaxy (the milky way). At the center of our galaxy is a black hole, the most destructive and strongest force known to scientists. When Earth aligns with these to strong cosmic entities what will happen to people and the planet?
