Henri Poincare Quotes

Absolute space, that is to say, the mark to which it would be necessary to refer the earth to know whether it really moves, has no objective existence.

Absolute space, in its own nature, without regard to anything external, remains always similar and immovable. Relative space is some movable dimension or measure of the absolute spaces, which our senses determine by its position to bodies, and which is vulgarly taken for immovable space.

For the first time driving that day I could feel the motion of the Earth. The Earth rushing through the emptiness of space. Spinning on its axis but they say you don't feel it, you can't experience it. But to feel it is to be scared and happy at once and to know that nothing matters but that you do what you want to do and what you do you are. And I knew I was moving into the future. There is not PAST anybody can get to, to alter things or ever to know what those things were but there is definitely a future, we are already in it.

Among the authorities it is generally agreed that the Earth is at rest in the middle of the universe, and they regard it as inconceivable and even ridiculous to hold the opposite opinion. However, if we consider it more closely the question will be seen to be still unsettled, and so decidedly not to be despised. For every apparent change in respect of position is due to motion of the object observed, or of the observer, or indeed to an unequal change of both.

Either CS (coordinate system) could be used with equal justification. The two sentences: the sun is at rest and the earth moves, or the sun moves and the earth is at rest, would simply mean two different conventions concerning two different CS

My earth is somebody's ceiling

As people used to be wrong about the motion of the sun, so they are still wrong about the motion of the future. The future stands still, it is we who move in infinite space.

Is it possible for a man to move the earth? Yes; but he must first find out another earth to stand upon.

After Galileo was convicted (for heresy by the Spanish Inquisition) for his theory that the Earth revolved around the sun, ... he replied, 'Still, the Earth is moving.'

When I walk I part the air and always the air moves in to fill the spaces where my body's been.

Facts do not constitute truth.

All motion is relative. Maybe it's you who've moved away by standing still.

There are no fixed points in space.

The Universe consists of non-simultaneously apprehended events.

The crude real will not by itself yield truth.

In some sense, gravity does not exist; what moves the planets and the stars is the distortion of space and time.

In my studies of astronomy and philosophy I hold this opinion about the universe, that the Sun remains fixed in the centre of the circle of heavenly bodies, without changing its place; and the Earth, turning upon itself, moves round the Sun.

For all our conceits about being the center of the universe, we live in a routine planet of a humdrum star stuck away in an obscure corner ... on an unexceptional galaxy which is one of about 100 billion galaxies. ... That is the fundamental fact of the universe we inhabit, and it is very good for us to understand that.

A moving shadow means more to us than a body at rest. We are no longer taken in by a fixed grin. We know that only death has a rictus.

It is indeed a matter of great difficulty to discover, and effectually to distinguish, the true motions of particular bodies from the apparent; because the parts of that immovable space, in which those motions are performed, do by no means come under the observation of our senses. Yet the thing is not altogether desperate; for we have some arguments to guide us, partly from the apparent motions, which are the differences of the true motions; partly from the forces, which are the causes and effects of the true motions.

I am sitting here 93 million miles from the sun on a rounded rock which is spinning at the rate of 1000 miles an hour... and my head pointing down into space with nothing between me and infinity but something called gravity which I can't even understand, and which you can't even buy any place so as to have some stored away for a gravityless day.

I feel all things as dynamic events, being, changing, and interacting with each other in space and time even as I photograph them.

This world has many rings, like Saturn, and we live now on the outmost of them all. None can say deliberately that he inhabits thesame sphere, or is contemporary, with the flower which his hands have plucked, and though his feet may seem to crush it, inconceivable spaces and ages separate them, and perchance there is no danger that he will hurt it.

It's proven that how time moves for you depends on where you are in the universe. It's relative to beings and other places. But on the level of being here on earth, if you are aware in a moment, one second can last a year. And if you are unaware, your whole childhood, your whole life can pass by in six seconds. But it’s also such a thing that you can get lost in.

Mathematics is not only real, but it is the only reality.
