There is none. So far, there is no real proof that there even are any aliens. Someone in the universe has to be first and there is no reason to think it isn't us. Crop circles are acts of vandalism, usually performed by college kids. Anyone who tramples a farmer's crop should have to work in the fields for a few months.
Check out the related link to see some messages we sent to outer space, it says some were decoded.
We did indeed send messages to space-- that one will get where it's going in 13,000 years! Clearly, the pranksters are having a field day, no pun intended. After all, why would aliens spell out gibberish in wheat when they could knock on the door of the radiotelescope which is right there?
They could have seen are wars violence and gotten scared I mean we kill other humans all the time why wouldn't humans kill them for testing alone if not out of our own fear for the unknown.
In which case the smart thing to do would be to avoid us entirely, not spell out gibberish in wheat.
no.
The outer circles show the difference between the two sides. The center where they join are the area they are the same. This is a great graphic way to show comparison of two things or ideas.
The concentric circles from the centre of a target are bull, inner ,magpie,outer
photo-receptors that read messages from the outer world, create these messages into electric currents which then flow to the brain.

Find them and then understand them.

Light coming up from the centre of the Sun goes through the outer layer where it encounters absorbtion by elements in the outer layer, and this gives rise to absorbtion lines in the spectrum.
S waves cannot travel through the outer core because they can only travel through solids, and the outer core is liquid.
A track 7m wide consists of two concentric circles. The circumference of the inner circle is 440m. Find, 1) the radius of the outer circle 2) the circumference of the outer circle.
In outer space there is no air medium for travelling of sound waves.so it is impossible for sound to travel through outer space ..!!
Yes, it can as long as it is not the tangent line of the outermost circle. If it is tangent to any of the inner circles it will always cross the outer circles at two points--so it is their secant line--whereas the tangent of the outermost circle is secant to no circle because there are no more circles beyond that last one.
