But after decades of many teams of experts using powerful telescopes, we still haven’t covered much territory. If the Milky Way is co...
The vast volume of the universe makes it very difficult to achieve interstellar travel, receive signals, or communicate with any potential far-off lifeforms (at least according to the laws of physics as we know them). Speeds are limited to the speed of light, which is around 300,000 km per second. It’s pretty fast. But even at that speed it would t...
Could it be aliens have crashed on Earth and the US government is just covering it up, as Republican Congressman Tim Burchett claimed in his reaction to the hearing?
