# Is Mathematics Limitless?

Mathematics allows us to transcend the boundaries of many realms that are inaccessible to our direct conception. For example, we can investigate the idea of infinity or explore spaces with more than three dimensions. Therefore, mathematics is often likened to a sixth sense.

We perceive the infinite as a conundrum and as something intangible. But the infinite also lies at the heart of many mathematical proofs. Meet the formula dubbed by mathematicians “the most beautiful formula in the world,” and come a bit closer to infinity.

Mathematics is limitless only if every intelligent being in the universe understands it. Scientists have frequently sent mathematical messages to any extraterrestrials who might be able to receive them. Learn about these attempts at contact, decode the “golden record” of the Voyager space probe, and listen to the radio signals of the Arecibo message.
