If there really is life out there then why not text them.
Hello from Earth, an Aussie website, has been set up that allows you to send SMS messages to Gliese 581d, the planet that is supposedly the most Earth-like planet outside the solar system.
One sobering message, from Sandeep in Abu Dhabi, said: “Please do not come to earth, it’s too polluted and the planet has almost reached its end.” Nothing like a bit of optimism eh?
We’re also not sure which network operators cover Gliese 581d, so couldn’t help but wonder what the delivery rates are.
