&gt;<i>&quot;During such events, massive amounts of heavy metals are formed. This collision, for instance, produced a lump of gold with the mass of our planet in just a split second.&quot;</i><p>We need to find a localized wormhole and go mine that.

&quot;The vision of VLBI is so sharp that if people were playing table tennis on the Moon we would see the moves of the ping pong ball. &quot;<p>I was under the impression that a radio telescope could only take a single pixel image. Are they using a different kind of receiver that can create a complete image? If so, how can they still increase resolution using interference?

Kudos to the scientists, astronomers and engineers who made this possible. This is so amazing. The reference to being able to see Ping balls on moon is unbelievable. We have such brilliant people in our midst!

&quot;In 2015 gravitational waves were detected that resulted from a collision of supermassive black holes.&quot;<p>&quot;The 2015 discovery was an event of another physical nature, much more powerful than the 2017 one, as it included the collision of supermassive black holes, each of the order of 100 millions of solar masses&quot;<p>This is not true. GW150914 was from the collision of two black holes of ~30 solar masses each.
