Four billion is still plenty of time.
Mostly I regard the Oort cloud as a hypothetical construct made necessary by theory rather than detected through observation (iow, a kludge), but a spherical concentric cloud doesn't seem too likely -- although it might have got there (if it is found to exist) when an earlier version of the Sun blew up.
Re: the 490K MPH
That velocity is of course relative. It would probably be more accurate to state that it is relatve to some fixed coordinate in the universe around us than the center. It is however the shared velocity of everything in this particular orbital distance from the center.
A hypothetical body wandering in from interstellar space would most likely be moving far slower especially to be slow enough to either be captured in solar orbit or to not impart a solar escape velocity to an impacted early Earth. (This raises the question of why such a high velocity collision did not impart a highly elliptical orbit after combining their inertia.) The length of time necessary to reach Earth over stellar distances is further increased... by a lot. This decreases the candidates for its source even more. This wandering rock would have to come from somewhere close to be at the required velocity to meet the criteria for our Moon maker.

Moving the convo over here.
That Astronomy article appears to be online, as a PDF:
Why is the solar system cosmically aligned?

Maybe the Oort cloud is the source of the background microwave radiation.
Okay. If the background microwave radiation is a local phenomenon then the Big Bang is in question.
The Galactic Environment of the Sun

“Our sun is also in motion. Relative to the average motion of the most commonly measured nearby stars, the sun moves with a speed of about 16.5 kilometers per second, or nearly 50 light-years per million years... The sun oscillates through the plane of the galaxy with an amplitude of about 230 light-years, crossing the plane every 33 million years. However, the sun’s motion relative to the local stellar neighborhood should not be confused with its movement around the center of the galaxy, since the whole solar neighborhood (including the sun) orbits the galactic center once every 250 million years. Just as we do not include the earth’s velocity around the sun when calculating the speed of an airplane (we are only interested in the ground-speed), astronomers do not include the sun’s galactic orbital velocity when describing its local motion.”
That's true, but that colloquilism causes large numbers of astronomers and physicists to incorrectly estimate the Speed of Gravity as being equal to the Speed of Light...whereas the correct answer when one factors the speed of the Sun's movement and overall galactic orbital velocity shows that the only way that our planets can revolve in a flat plane around our Sun with such coincidental momentum is for the Speed of Gravity to be vastly faster than C.
If Gravity was slower, as the Sun head North, the planets' orbits would look like a wedding cake with each rotation being further South as you went outward from the Sun from one planet to another...because there would be a gravitational lag by the time the Sun in its old position affected a planet.
TVP appears to have discovered the “pushing gravity” model.

The Top 30 Problems with the Big Bang (Van Flandern)
http://metaresearch.org/cosmology/BB-top-30.asp
“(2) The microwave ‘background’ makes more sense as the limiting temperature of space heated by starlight than as the remnant of a fireball.”
Quantum Entanglement And Free WillDistance between Mirror Universes. A Chiral "Oscillating Quantum Vacuum Lattice" guided by "Big Bang-entanglement" could lead to the explanation how the Quantum Mechanical World is able to mimic Relativity... Gravity is the IMBALANCE between two opposing PUSHING forces: the Vacuum oscillatory impulse force, averaged over time (=Dark Energy), against less powerful Graviton Vacuum oscillatory impulse force, induced on the vacuum by mass. Not only gravity but all 4 forces are supposed to have the same dual imbalance system as origin. Thus the attraction forces are the reduction of the repelling vacuum force and repulsion is the increase of the repelling vacuum force. This means that there is not a maximum on all 4 fundamental forces of nature based on the maximum (ZPE) vacuum force, because repulsion is based on the increase of this force. Only attracting forces can have a maximum based on this system. All Fermionic energy / mass has its origin in the vacuum oscillations... Recently the scientists J.P. Luminet, J. Weeks, A. Riazuelo, R.Lehoucq and J.P. Uzan proposed, that according to the structure found in the WMAP, the universe resembles a finite 12 lobed Dodecahedron shaped soccer ball. However, according to this new Fractal Big Bang model, the universe is more like a 12 lobed raspberry. In this new Fractal Big Bang model, the hotter areas in the MAP picture are supposed to be the Vortices of the Fractal Big Bang splitting process, during the expansion of the Big Bang leaving groups of Black Holes behind. These groups of Black Holes are able to produce gas by the chiral vacuum system and create massive gaseous envelopes, which show up as "Hotter" areas in the MAP Probe picture. The Hotspots are supposed to be the connection to the Progenitor Gaseous Halos which are found in the Deep Field High-Z Subaru survey called Massive Halos. The Massive Halos harbour so called Lyman Alpha Emitters (LAEs) and Lyman Alpha Break Galaxies (LBGs) see before (K. Shimasaku).

I've not heard too much about that, if anything. What happened?
Ooh WOW! Another one-liner.
