The discovery team nicknamed the object "Farout," and its provisional designation from the International Astronomical Union is 2018 VG18. Preliminary research suggests it's a round, pinkish dwarf planet. The same team spotted a faraway dwarf planet nicknamed "The Goblin" in October.
The object is more than 3.5 times the current distance between Pluto and the sun (34 AU), and it outpaces the previous farthest-known solar system object, the dwarf planet Eris, which is currently about 96 AU from the sun. NASA's Voyager 2 spacecraft recently entered interstellar space at about 120 AU, leaving the sun's "sphere of influence" called the heliopause, where bodies experience the solar wind.
The record Farout now holds is for the most-distant solar system body ever observed. That doesn't mean no other objects gets farther away from the sun than 120 AU. In fact, we know some that do. The dwarf planet Sedna gets more than 900 AU away on its highly elliptical orbit, for example...
The research team is scoping out these ultradistant objects to search for the gravitational influence of a theorized super-Earth-size Planet Nine, also called Planet X, that researchers have posited orbits in the extreme reaches of the solar system. The movements of several distant bodies have suggested the existence of this planet, which would be extremely faint and hard to locate.
Because the proposed Planet 9 is so distant — between hundreds and thousands of AU, researchers told Space.com, the planet can alter the orbits of objects far too distant to be strongly influenced by the inner solar-system planets. That means that looking for trends in the orbits of objects like Farout can point the way to the mysterious planet, giving researchers hints of where to look for it and chances to test the powerful telescopes that might someday spot it.

GN-z11 is a high-redshift galaxy found in the constellation Ursa Major. GN-z11 is currently the oldest and most distant known galaxy in the observable universe. GN-z11 has a spectroscopic redshift of z = 11.09, which corresponds to a proper distance of approximately 32 billion light-years (9.8 billion parsecs).

Inflationary Expansion. And the current observations lead some to thing that it is speeding up!
At least one of the three following must be incorrect:
1. The Big Bang dating is incorrect.
2. Red-shift assumptions are incorrect.
3. God intervened (though Sheldon doesn't believe).

#8 Do they even have women in bikinis in today’s tv shows?
Judy Carne looked good in a bikini back then.
