Without using pictures or your astronaut buddies, can you, personally prove the world is round?

Two possibilities not previously mentioned: first, phone your various friends around the world, and ask them the time! You will then find out that the sun is at a different height in the sky at different places. So at least the world is not flat, since the sun is very much farther out than the distances between any two points on earth.\n\nSecond, wait for a lunar eclipse. This is the Earth's shadow projected on the moon. It is round. The Earth is not a disk (see first experiment) but casts a round shadow: a sphere seems indicated. In fact, it is a sliughtly flattened sphere (ellipsoid, in fancy language)

hunnnnnn and i  bet you think ..earth  is flat

Oh no, you've figured out my hoax!!! You busted me, you're right, its not round. Sorry, I get silly sometimes. If you are at a position when the moon passes directly perpendicular to you relative to the sun's position then you will see a perfect half lit moon. you can simulate this with a big right triangle by taking a golf ball or some other ball and placing it at the  90 degree corner and placing a flashlight at one of the other corners pointing directly at the ball. Now line up your sight from the third corner and you should see a perfect half lit ball. :)

Yes I do, but as for showing proof how would you do that it would be kind of like proving that there is or is not a god.

The evidence  against is actually proof. The Moon, rocket fuel, etc. all would act differently than Hollywood could anticipate. \nSee Skeptics Magazine and Skeptical Inquirer for pros and cons.\nFor instance, the hammer on the astronaut's belt swings as it would in a lower gravity. It looks fake, but shows they are in a lower gravity.\nThings like inertial guidance system use in airliners, scientific papers all would be hard to fake and who would have thought to write them otherwise?

Definitely, we've even used Hubble to detect the flag & footprints. Our gov. would never lie about something on that scale. Considering the size of the universe, Its really not that big of an accomplishment to warrant an elaborate network of lies\n\nFor an incredibly in-depth analysis of pictures, facts and commentary please see the source link.

A point does not have a direction. So I guess the answer is yes.

if ur asking if we, as humans, can be sure the no one else exists on the other planets? then no..no one can be so sure, but the facts gathered about the other planets, such as chemicals in the air, etc... can tell something about the planets..

Yes, the moon landings were real. Some people still maintain that the Earth is flat - no one takes them seriously; no one should take the 'moon landing is a hoax' seriously either.\n\nFirst, we have material evidence: rocks from the moon, photographs taken from there, the word of thousands and thousands of people who worked on the project, etc. Even more damning, the astronauts left a prism mirror on the moon that anyone with a medium laser can target to see the laser reflected! And do you really think the Russians wouldn't have raised a stink if any of their, oh, dozen thousands physicists had found something dodgy? Or do you think they all failed to know about something like 'heat and air on the moon'?\n\nThen we have so much stuff in space now, like thousands of satellites, probes on Mars, and even outside the solar system, what is so unlikely about landing on the moon, which is incredibly close to us, astronomically speaking? It's only 3 days away!\n\nAll the arguments from conspiracy theorists have been easily rebuked; the three sites at the end give a good rundown. The most commons were:\n\n- There is a flag waving! there is no air on the moon! Hoax!\nHum. The flag is not moving, notice? It *looks* like it's in the middle of a wave, because it was built like that! The NASA, incredibly enough, figured out that there was no wind on the moon, and that a limp flag would be a tad disappointing, so simply attached the flag to perpendicular poles in that position. Try it in your garden, it will take 5 minutes.\n\n- The photos are too good! That's not possible!\nNo, they took hundreds of pictures, and you only see the good ones, just like any amateur photographer will tell you. \n\n- The footprint doesn't look at all like the one you leave in sand!\nThat's because the moon is not covered in sand... Sand is created by erosive forces grinding up rock, like the sea or plate tectonics. The moon has no erosive force, since it's dry and not volcanic. The dust there is rocks vaporised by meteoric impacts, which looks a lot like flour. Put a heap of flour on the ground and watch your footprint: very similar, no?\n\nSo, no, the government is not involved in *this* coverup :-)

all you have to do is go to google, and type in googleearth, u can see the who world, by satilite pictures! It is really cool!

look around you, can you testify the existance of GOD and the universe?

No one has that proof.  Just like no one has proof there are aliens and UFO's.  It's a matter of your personal beliefs.

I would think pictures could be pretty good proof.  Did they show you doing something?

NASA DOES NOT KNOW.\neveryone is only guessing.\nthere is no specific,absolute proof.\nit's all assumptions.

it is a complete hoax. nothing humans do can tilt the axis of the planet. all human cities are like weigh like 0.01% of an average mountain range.

Actually, despite what has already been said...you can. However, define "see". It is very difficult, if not impossible to see with the naked eye, but can easily been seen using hi res cameras on satellites.\n\nSee here from the European Space Agency:\n\nhttp://www.esa.int/SPECIALS/Proba_web_site/SEMTTHGHZTD_2.html
