How long did it take from blast off to touch down on the moon? They are talking about humans going to Mars, how long will the trip take, 6 months? Our earliest robotic exploration vehicles (launched in the mid-70's) are now just crossing the outer reaches of the solar system. Our nearest neighboring star is 4.2 light years away. Obviously, we aren't going anywhere with our current means of propulsion. So, what can we do and how soon will it take to do it?

a subculture of cybernetic androids, and all the bad effects from the year 2012 remained toying with our minds and happiness. Followed by an earth rotting pandemic launched by a nano-technically inclined 8 year old genetic engineer/ punk.

Do you think we would survive?
What do you think would happen...

links would be appreciated

if the earth is 24 thousand miles round and there is 24 hours in a day then the earth must be spinning at 1.ooo mph nearly twice the sound barrier so why dont we hear this

it has no tail but is just visible with the naked eye,through a cheap spotter scope it is huge!. obviously the sun at this time is in the southern hemispere so that would explain the lack of tail but would like to know if this object is "known" and if it is what name does it go by? thanks!

I need some help studying for my Earth and Space Science exam tommorow. Any info you have on my question would be very apreciated, and would help me out a lot.

Question 1:
Drill a hole all the way down to a depth 0.5 metre above the centre of earth. For that we need a long casing to stop sloughing and ground water into the hole. This is an ideal closed end casing which is strong enough to withstand high pressure and temperature inside the earth. Now put a sphere of 1 kg mass of 1 metre diameter at/ on the base of hole. The distance between the centre of the earth and the centre of the sphere is 1 metre.

Now apply the same universal law of gravitation to the two masses. Can I calculate the value of “g” (as Newton drive for his equation on the surface of the earth ) at this point by the following equation.

F = G M m/R^2 g = GM/R^2 , Where R = 1 metre, therefore R = GM, g= 3.98 x 10^14 m/sec^2. So Weight of this mass at o.5 metre above centre of earth =mg = 3.98 x 10^14 N. If not, please explain and why g = 10.7 m/sec^2 in inner core?

Question 2:
Now push the casing further down and past the centre of earth by half a metre. Now Again put a sphere of 1 kg mass of 1 metre diameter at/ on the base of shaft such that the centre of the earth and the centre of the sphere coincides. (Just like white and yolk of boil egg)
Apply the same universal law of gravitation to the two masses. What will be the value of “g” and the gravitational force?
F = G M m/R^2 g = GM/R^2 , Where R = zero metre, therefore g= 0 m/sec^2 or infinity & F=zero or infinity
If not, please explain why?

What is the value “g” at the centre of gravity of the earth?

Question 3:

Now push the casing further down and past the centre of gravity of earth by one km. Now remove the sphere and drop a stone from ground surface or the top of casing. So where will be the resting position of stone, centre of gravity of the earth or at the base of hole?

In my years as an avid astronomy fan, I have found the following to be very common misconceptions:
1) People think the Pleiades are the little dipper.
2) People are surprised to find out that we can see Saturn easily with the naked eye.
3) Many think that Polaris is the brightest star in the sky.
4) Most have almost no concept of the vast differences in the distances of stars we see.

I'm interested what other astronomers, professional or informed amateur, have found that most casual observers misunderstand.

Could God have created the Universe 6000 years ago, but made it to show in scientifical measurement to have been created billions of years ago with the principal of the big bang correctly explaining how the universe had started?

I know at some times of the year and in some places on earth, the moon is only briefly visible either at the beginning or the end of the night.

Would the full moon be visible in New York's Cental Park at midnight in April?
