so far all of you are wrong,, youve given me the distance around the circumference,,, forget about the word wrong of divide,,, this is not of importance!! NOW LETS GET TO IT,,

YOU HAVE A 16" CIRCLE,, AND YOU NEED TO MARK OUT 12 EQUALLY SPACED SPOTS ON THAT CIRCLE.... WHAT IS THE FORMULA FOR A STRAIGHT LINE LENGHT BETWEEN SPOTS? FOR THOSE WHO WANT TO GIVE ME THE CIRCUMFERENCE TRY PLOTTING THOSE POINTS ON THE CIRCLE WITH EITHER COMPASS OR RULER? THE CIRCUMFERENCE IS NOT WHAT I NEED!!! WHAT I DO NEED IS THE STRAIGHT LINE DISTANCE ACROSS THE ARC BETWEEN POINTS?

My reasoning is: If it was possible to dig a tunnel to the centre of the earth, at the actual centre the mass of the earth would be equally distributed all around you and would cancel itself out; you would effectively be weightless?

Does the same reasoning apply to the singularity of a black hole, indeed does a singularity have a centre. If I am correct in my reasoning, what implications does this have, ie having a zero gravity adjacent to infinite gravity.

Hello everyone. I just got a new scope for my birthday. Ive never looked at the stars before but I love astronomy. I aimed at Jupiter tonite and was dissapointed in the result that I got. No matter what lens I used the planet never changed shape from a round ball of light. Very blurry as well. From what I can tell my scope only has one focus. Here is all the info about my scope...

Science Tech
Precision Optics 525 Power
Astrolon Telescope.

My Lens' : 20mm, 12.5mm, 9mm, 4mm. There power is shown as 35x,56x,78x,and 175x respectivly.
It also came with a 3x Barlow. With the Barlow, the power is listed as 105x, 168x, 233x, 525x respectivly.

What am I doing wrong? Shouldnt I been able to see Jupiter clearly. I did try many other stars and same result. The only really exciting thing I did see was 2 of Jupiters moons that were lined up almost perfectally. Did my wife buy me a piece of junk, or was it just a bad night, or do I need different lens'. Please let me know asap.
