this is TRIPPY…

This is a hypothetical puzzle inspired by the arecibo message.  What do you think can you solve this thing?  Here is the background on this unusual and fun exercise:

In a post on the MPISSR website, he asked the Internet to decode the message and answer the following questions:

1. What is the typical body height of our interstellar counterparts?
2. What is their typical lifetime?
3. What is the scale of the devices they used to submit their message?
4. Since when have they been communicating interstellar?
5. What kind of object do they live on?
6. How old is their stellar system?

Here are the rules of the puzzle as cited on the website:

1. No restrictions on collaborations.
2. Open discussion (social networks etc.) of possible solutions strongly encouraged.
3. 3 hints to the solutions can be offered as per request.
4. Send your solutions to me via e-mail (heller@mps.mpg.de), twitter (@DrReneHeller) or facebook (DrReneHeller). Human-readable format and the format of the message are allowed.
5. On 3 June 2016, a list of the successful SETI crackers (in chronological order) will be released.

Feel free to post your ideas about this thing and check back in June when they start to release the answers.

We hope you enjoy!
