Honey, bless your heart for asking that. The evidence that the moon wasn't formed from an accretionary disc includes its lack of a sizable iron core compared to Earth, the similar isotopic compositions of Earth and the moon, and the moon's painfully slow rotation. Like, seriously, it takes the moon longer to spin around than it does for me to dish out this response wearing high heels.

Creation of the universe begins with the 'Big Bang', some 11 billion years ago. Stars formed and grew old, and new stars formed, but for billions of years there was no earth. In the neighbourhood of our sun, a giant star exploded as a supernova, an event that scientists see occasionally. A very small part of the material given off by this explosion was captured as an accretion disc in orbit around our sun. This disc broke up into gaseous balls, one of which was to become our earth. It cooled until the hot gases condensed into a rocky sphere orbiting the sun. A billion years later, primitive life forms began to appear.
They don't. Uranus spins on a "sideways" axis with retrograde spin. Venus also has a retrograde spin. Most spin in the same direction though. This is probably because of how the Solar System was formed, from a spinning disc of material.
It was not known how the Moon formed until the Apollo astronauts brought back Moon rocks. It was then found that the rocks were similar to the Earth's showing that a planet had hit the Earth and scooped out a chunk of the mantle. Prior to this it was thought that either the Moon was a captured asteroid or had formed at the same time as the Earth from a disc of dust.
Most Discs Will Have Little Brushes On The Reading Side But They Are Very Small. All You Must Do Is Stick Your Disk Into The DVD Player/Portable DVD Player And Follow The Instructions. Often There Will Be A Warning On The Disc Saying "NOT TO BE USED ON AN XBOX OR THE PLAYSTATION SERIES!" As Faults Can Occur When Using Those Discs With Gaming Stations. What You Have To Do After Inserting The Disc Depends On Which Disc You Are Using. There Are Hundreds Of Manufacturer's That Create These. A Phillips Portable DVD Player Lens Cleaner Will Require You To Listen To A Person Talking About What This Disc Will Do, And You Need to Skip Ahead A Few Tracks To Start The Cleaning Process. Others Require You To Do Things Like Watch A Short Clip As It Cleans So You Can See The Improvements.
They believe the planets formed from a disc of gas and dust called a "protoplanetary disc".
No
Mercury presumably formed in the same manner Earth did, from a disc of matter circling the Sun. Its orbit is more elliptical (varying) than Earth's, which suggests a greater variation in the initial momentum of its constituent matter.

Meteoroids, like the planets, were formed from the solar systems accretion disc. The rotational energy kept the entire system mass from falling into the Sun. the rest of the material continued to orbit and coalesce. The accretion disc was formed from interstellar dust and gas from previous stars that had burned through their fuel and exploded.
Growing scientific evidence also points to genetic factors in disc herniation, especially in families with a history of predisposition to early-onset sciatica and disk herniation.
An accretion disc is a structure formed around a central object, often a black hole or a young star, as it gathers material from its surrounding environment. The material in the disc spirals inward due to gravity, releasing energy in the form of heat and light. Accretion discs play a key role in powering some of the brightest phenomena in the universe, such as quasars and X-ray binaries.
Planets were not "invented" but rather formed naturally as part of the process of stellar evolution. Planets are thought to have originated from a swirling disc of gas and dust surrounding a young star, known as a protoplanetary disc, eventually accreting into planetary bodies.
When a doctor refers to a disc space as "unremarkable," it means that there are no abnormalities or concerning issues detected in that particular region of the spine. This term suggests that the disc space appears normal and there are no visible signs of injury or disease.
i have been miserable with pain in neck and shoulders and more,went to the er and the results show there is straightening to the normal curvature.on c2-c3 there is moderate disc bulging. without disc herniation. c3 and c4 there is broad disc herniation present extending to the right midlin.There is evidence of central canal and right sided forminal narrowing.on c4 - c5 broad disc/ridge complex is present.there is mild centralcanal narrowing and mild left foraminal narrowing. c5 and c6 there is mild disc bulging without disc herniation.Cuts at lung aspices are unremarkable.multilevel disc disease.
