To the edge of the Universe: then beyond far enough to watch it expand towards me. The big question, what is Universe expanding in to, and is there such a thing as the edge?

There is no edge of the universe.  The universe is expanding, yes, but it is space itself that is expanding.  Think of it like a balloon being being inflated.  The balloon is expanding, but there is no edge of the balloon to stand on, but the distance between everything on the surface of the balloon is increasing.

I would want to go to Pluto, Keiper Belt, and the nearest black hole (from a very safe distance). 

The Kuiper belt would actually be pretty boring.  The estimated mass of the entire Kuiper Belt is less than 2% the mass of earth.  Considering that the size distributions of Kuiper Belt objects follow a number of power laws, specifically the overall number of objects being inversely proportional to some power of the objects diameter, and the vast size of the Kuiper Belt, if you were to go there, you would find yourself in almost entirely empty space.  Very little matter actually occupies this region, and while there are several bodies that are greater than 100km in diameter, the entire region is so huge that you are very likely not going to encounter anything at all.z

Zeta Reticuli, the home world of our little grey UFO friends.

No...  Just, no...

Zeta Reticuli is a binary system.  Despite the fact that magnetic and radiation features of these starts would pose a challenge to the evolution of life in such a system, we have thoroughly examined this system looking for any sign of exoplanets.  At just under 40 light years away, the existence of exoplanets in this system would be ideal for study.

There are a few ways to detect exoplanets- 1) Is to look for gravitation effects in their star.  As the planet orbits the star, the planets own gravity will tug on the star causing it to wobble slightly.  2) Dimming of the star as the planet transits in front of it.  This can give us a good deal of information about a planet, but requires that planet to pass between its star and earth. 3) Infrared radiation- Some of the starlight that hits the planet will be converted to infrared radiation.  If a star system has an excess of infrared radiation, we can determine the total mass of the planets orbiting the star.

Careful examinations of the Zeta Reticuli system over the past couple of decades have ruled out any excess infrared radiation.  Combined with the deficiency of heavier elements in this system, and models for how such a system would form, both the chemical characteristics of the system, our models of star formation, the lack of excess infrared radiation, and the lack of any noticeable gravitational effects, are all consistent for a binary system that has no planets.

I have some family members who are way into UFO conspiracy theories, so I am going to further debunk this...

The first connection between Zeta Reticuli and space aliens came from the Barney and Betty Hill incident.  The couple was supposedly abducted by aliens in the 1960's and under hypnosis recalled a "star map" of where they were taken to.  This star map was then published in a book about the incident.  An elementary school teacher, upon reading the book, decided to try to decipher the star map and figure out where the couple was taken.  Based on this star map, which only included 15 stars, he determined that couple was taken to the Zeta Reticuli system.  To reach this conclusion, he made several assumptions about the star map.  One assumption was that the star map only showed stars similar to our own sun.  He also assumed that one of the stars depicted on the map was indeed our own star.

On a 1980 episode of Cosmos, Carl Sagan himself debunked this star map.  He showed how you could take any random 15 points and reach the same kind of conclusion.  Finally, in the 1990's, actual high-detail measurements of star locations showed that some of the stars in this map were actually much further away than assumed, meaning the map would not have been accurate from Zeta Reticuli even if you bought into the methodology used to arrive at that conclusion in the first place.

The second connection between Zeta Reticuli and space aliens is Bob Lazar.  If you don't know, Bob Lazar claims to have worked at Area 51, reverse engineering alien technology.  He claims that he worked on a crashed alien space craft that came from the Zeta Reticuli system.

Lazar has made a career out of his claims.  However, some of his claims are demonstrably false. For example, he claimed that the spacecraft he worked on was powered by element 115 (at the time he made the claim this element had not yet been synthesized). He claimed that this element generated artificial gravity, via gravitational waves, and light bends around it.  Since he made these claims, we have successfully synthesized various isotopes of element 115, now known as moscovium, none of which bend light or generate gravitational waves as he described.  Also, like other heavier elements, it rapidly decays and is not stable.

Other claims he has made about how this alien technology works, such has how magnetism and gravity interact, are also demonstrably false.  He also claims to have degrees from MIT or CIT, but none of these schools have any records of him, and no one who has gone to these schools has any memory of him.  He claims to have worked for EG&G and Los Alamos, both of which say they have no records of his employment.  Further, anyone who has a master's degree in physics, which he claims to have, would immediately know his claims regarding gravity and magnetism are completely nonsensical.

Mr TVGuy again reveals himself to be widely educated, intelligent and well informed.
