The stealth extraterrestrial communication using gravity waves in higher dimensions Scientists are now completely at shock to learn that most of the extraterrestrial communication takes place not in the frequencies terrestrial communication happen. The advanced extraterrestrial civilizations communicate using gravity waves, the dark matters and interfaces through the higher dimensions. Reverse engineering this technology is possible. Defense scientists in many countries are trying to understand the mechanisms. The electromagnetic spectrum is absent in higher dimensions. It is replaced by the gravity waves that dominate the Hyperspace. The outer edge of the universe confirms this. The biggest problem that challenges our capabilities in listening to advanced extraterrestrial civilization is that they are far advanced and use stealth extraterrestrial communication using gravity waves in higher dimensions.
