@juiced resolved the fourth riddle on telegram
For more details on his research work I let you read (Telegram/Discord/Facebook)
To summarize the answer to the fourth riddle.We had in the fisrt hint the x-rays that revolutionized the medical field discovered by Wilhelm Röntgen.
The hexadecimal points to this link bit.ly/eFf3c. Link that shows us, the Doppler effect in practice. Discovered by Christian Doppler.
Third hint was a password locked archive hidden on our website. The password was as follows: RontgenDoppler
Once this archive opened it let appear an image of the constelation of the Cignus with surrounded in red the zone where it finds Cignus X 1 (the space is great excused for the lack of precision).
Cignux X 1 is a black hole discovered by a group of researchers (Charles Thomas Bolton). To discover it they observed a strong emanation of x-ray around a star. That emanation didn't make sense. Doppler technology and light variations proved that this star turned in a few days around something then unobservable emanating a lot of x-rays. This is the first time that the existence of a black hole has been proven. Until then it was a hypothetical phenomenon.
The meaning 1 + 1 = 3 : x-ray + doppler = proof of the existence of a black hole !
