Gravitational Interactions Quotes

The content of physics is the concern of physicists, its effect the concern of all men.

Voyager found Saturn to be a planet with a complex interior, atmosphere, and magnetosphere. In its rings - a vast, gleaming disk of icy rubble - the mission recorded signs of the same physical mechanisms that were key in configuring the early solar system and similar disks of material around other stars.

You know, there was a time, just before I started to study physical science, when astronomers thought that systems such as we have here in the solar system required a rare triple collision of stars.

Gravitational and electromagnetic interactions are long-range interactions, meaning they act on objects no matter how far they are separated from each other.

The origin of galaxies is one of the fundamental questions of astronomy, and that's what I've been studying.

It now appears that essentially every star has a planetary system. In the very beginning, we thought at best half.

We are the laws of chemistry and physics as they have played out here on Earth, and we are now learning that planets are as common as stars. Most stars, as it turns out now, will have planets.

The universe has told us the most common types of planets are small planets, and our study shows these are exactly the ones that are most likely to be orbiting Alpha Centauri A and B.

Every type of ring behavior we have seen around Jupiter, Uranus, or Neptune can be found in orbit around Saturn. And Saturn's ring system offers the greatest promise of understanding processes in operation within all disk systems, not just those found around planets.

As our sensitivity improves, we are finally seeing planets with longer orbital periods, planetary systems that look more like our solar system.

That so many binary or quasi-binary KBOs exist came as a real surprise to the research community.

In a sense, the searches for both magnetic monopoles and gravity waves are very similar. But, theoretically, gravity waves are more solid.

The Saturn system is a rich planetary system. It offers mystery, scientific insight, and obviously splendour beyond compare, and the investigation of this system has enormous cosmic reach... just studying the rings alone, we stand to learn a lot about the discs of stars and gas that we call the spiral galaxies.

Pluto and its brethren are the most populous class of planets in our solar system.
