Gravitational Interaction Quotes

Spacetime tells matter how to move; matter tells spacetime how to curve.

I thought that there must be an easier way to explain how a gravitational wave interacts with matter: If one just looked at the most primitive thing of all, 3D floating masses out in space, and look at how the space between them changed because of the gravitational wave coming between them.

Every particle of matter is attracted by or gravitates to every other particle of matter with a force inversely proportional to the squares of their distances.

You sometimes speak of gravity as essential and inherent to matter. Pray do not ascribe that notion to me, for the cause of gravity is what I do not pretend to know, and therefore would take more time to consider of it.

I suppose I'll have to add the force of gravity to my list of enemies.

Consider now the Milky Way. Here also we see an innumerable dust, only the grains of this dust are no longer atoms but stars; these grains also move with great velocities, they act at a distance one upon another, but this action is so slight at great distances that their trajectories are rectilineal; nevertheless, from time to time, two of them may come near enough together to be deviated from their course, like a comet that passed too close to Jupiter. In a word, in the eyes of a giant, to whom our Suns were what our atoms are to us, the Milky Way would only look like a bubble of gas.

Gravity is a mutual affection between cognate bodies towards union or conjunction (similar in kind to the magnetic virtue), so that the earth attracts a stone much rather than the stone seeks the earth.

And then everything was in the hands of gravity, which has never had much love for the terminally stupid.

Gravity is not controlled physically in us by one of the 5 ordinary senses. We always reduce a gravity experience to an autocognizance, real or imagined, registered inside us in the region of the stomach.

There are some galaxies that not only teach us things but are just gorgeously beautiful to look at. My favorite example is the Antenne, which is a pair of colliding galaxies.

All mass is interaction.

There may be hundreds of small seed planets - or planetesimals - which grow in the disk of matter around a star.

When discs form around stars, there is interaction of angular momentum between disc, planets and parent star, and this interaction affects the rotation of the parent star, and that will affect the lithium abundance.

It now seems logical that all the stars, like our own sun, must have formed with a system of planets around them.

Most Jupiter-sized planets orbit the mother star in a highly elliptical orbit. This means they will often cross the orbit of any Earth-like planet and fling it into outer space, making life impossible. But our Jupiter travels in a near-perfect circular orbit, preventing a collision with any Earth-like planet, making life possible.

All the evidence, experimental and even a little theoretical, seems to indicate that it is the energy content which is involved in gravitation, and therefore, since matter and antimatter both represent positive energies, gravitation makes no distinction.

In 1999, my team discovered that the star Upsilon Andromedae was circled by three gas-giant planets - the first distant multiplanet system ever found. That same year, other researchers observed the first 'transit' of an exoplanet - a planet blocking out a small fraction of the starlight as it passes in front of the star.

You can be only a modest distance away from the gravity brane, and gravity will be incredibly weak.

The New Horizons Pluto mission will be the first mission to a binary object and will help us understand everything from the origin of Earth's moon to the physics of mass transfer between binary stars.

Any two particles in the universe attract each other through the gravitational interaction.
