If the launcher gives the projectile a muzzle velocity of 25m/s, what is the range of the range of the projectile? [ hint: the acceleration due to gravity on the moon is only one sixth of that on the earth.]

Experts have only been able to conjecture how the Egyptian's were able to build the pyramids. Has anyone asked this question. Are we sure the Egyptian's built them? Could it have been an advanced intelligence from another world that built them as markers so if a space traveler saw them from space they would know they were here?
The pyramids are one of the few m anmade things that can be seen from space.

Last Tuesday coming home going south towards the Manzano Mountains in New Mexico, I saw a huge reddish ball somewhat like the harvest moon. It was still and then slowly subsided out of view. It was too big for a hot air balloon and someone told me they don't fly at night. It was 9:30 p.m. Did I see a UFO?

I think it would work well, but Alan says that it would need air to ignite the propellant.

Many pople believe that our government knows something about UFOs and alien beings that they are keeping secret. But what if the truth really is that they know NOTHING about UFOs/aliens? What could the govt. say or do to convince UFO buffs that there is no coverup at all?

If the president says there is no coverup, he will be accused of lying. If the military opens up Area 51 to the public, people will say they moved the UFOs somewhere else. Is there anything that would convince believers that there are no aliens here on Earth (assume that is the truth)?

The name of our galaxy is the Milky Way Galaxy, but what is the name of our solar system. I know that the sun and our solar system are located within the Orion Arm, but every book I read referes to our solar system as The Solar System. Hhmm maybe that's the name of it and to think we name everything on and off our planet but our very own solar system.

I saw a TV program the other day that went into great detail of what would happen to our planet when the sun changes stages and eventually dies off... why is nobody concerned with this? Just because you will not live to see it does not mean you shouldn't slowly work towards a solution… at least for future generations. I heard an astronomer laugh and say "We have 5 billion years to prepare for this"... this is no laughing matter to me.
