Even at the speeds mentioned in the articles (10,900 m/s), it would take too long for something from the closest star system to reach Earth.Alpha Centauri is at roughly 4.3 light years from Earth. That's 40.7 trillion km... at 10,900 m/s (39,240 km/h), you're looking at 118,000 years of travel for a one way trip.My guess is that either they can reach speeds 99.9999% close to the speed of light, they can warp space, or they're time travelers.
The speed they're using on Earth is not their max speed of course.To travel from planet Nib to Earth for example. they use Wormholes for expedient travel.
Everyone knows that the only holes in space be BLACK. FACK! I be certan dat Professer Wiggs be along shortly to sexplain dat to ya'all. 'n' sheit. Black Holes matter. 'n' sheit.
On Planet Nib, everyone is black and flat.
They have been prevalent since we first got/used nukes.They have even reportedly shutdown nuke missile systems.Literally tens to hundreds of witnesses who held high ranking military positions have come forward and confirmed this, to deaf ears of course.https://www.express.co.uk/news/weird/913279/Aliens-in-UFOs-prevented-nuclear-WW3-between-US-Russia
