Quotes About Planets

It is our firm belief that we shall one day learn the plan of the entire multiverse and travel at will from Sphere to Sphere, from realm to realm, from world to world, travel through the great clouds of shifting, multicoloured stars, the tumbling planets in all their millions, through galaxies that swarm like gnats in a summer garden, and rivers of light–glory beyond glory–pathways of moonbeams between the roaming stars.

He wrote authoritatively on magnetism, tides and the motions of the planets, and fondly on the effects of opium.

in the words of the physicist Michio Kaku, who goes on: "In some sense, gravity does not exist; what moves the planets and stars is the distortion of space and time." Of

In some sense, gravity does not exist28; what moves the planets and stars is the distortion of space and time.

supernova explosions could have generated the necessary heat to create the heavy elements that led to the formation of rocky planets and, eventually, us. (credit

Most schoolroom charts show the planets coming one after the other at neighborly intervals—the outer giants actually cast shadows over each other in many illustrations—but this is a necessary deceit to get them all on the same piece of paper. Neptune in reality isn't just a little bit beyond Jupiter, it's way beyond Jupiter—five times farther from Jupiter than Jupiter is from us, so far out that it receives only 3 percent as much sunlight as Jupiter.

electrons are not like orbiting planets at all, but more like the blades of a spinning fan, managing to fill every bit of space in their orbits simultaneously (but with the crucial difference that the blades of a fan only seem to be everywhere at once; electrons are).

Of even more importance, residents of other planets are God's creation, His children, just as we are, after all.

It would take six months to get to Mars if you go there slowly, with optimal energy cost. Then it would take eighteen months for the planets to realign. Then it would take six months to get back, though I can see getting the travel time down to three months pretty quickly if America has the will.

This is what confuses me. People say, 'I believe that we landed on the Moon' but then they find it really far fetched that there can't be other planets where little men haven't travelled to ours.

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.

My father was always very interested in space. I watch Star Trek and all those things, but I always had a different picture in my mind... maybe closer to Alien. I don't see it in space as much as I do see it in different planets, with each having its own strange characters.

Once solved, the severe handicaps imposed on space exploration by the weight and chemical limitations of rockets would no longer apply. The whole timetable of our conquest of the planets in our solar system would be tremendously speeded up, from hot Mercury all the way out to frigid Pluto.

I have a vision of a Galaxy overrun by mankind from Core to rim. Of four hundred billion stars each enslaved to the rhythm of Earth's day, Earth's year. I have a vision of a trillion planets pulsing to the beat of a human heart.

Everybody has busy lives, but you can tell people, 'Go outside and look at the night sky. We've been able to demonstrate that every star you see probably has a planet around it.'

All indications are that three and a half billion years ago, Mars looked like Earth. It had lakes. It had rivers. It had river deltas. It had snow-capped peaks and puffy clouds and blue sky. Three and a half billion years ago, it was a happening place. The same time on Earth, that's when life started. So did life start on Mars?

For the greater beauty of the instrument, the balls representing the planets are to be of considerable bigness; but so contrived, that they may be taken off at pleasure, and others, much smaller, and fitter for some purposes, put in their places.

Indeed, Isaac Newton himself, who introduced the concept of immutable laws which guided the planets and stars without divine intervention, believed that the elegance of these laws pointed to the existence of God.

Liquid water is the universal solvent, the mixing bowl where the first DNA probably got off the ground. If liquid-water oceans are found on these planets, it could alter our understanding of life in the universe. Journalists in search of a scandal say, "Follow the money," but astronomers searching for life in space say, "Follow the water.

If a planetary twin of the Earth exists in space, it has eluded us so far. But we have found about fifty super-Earths so far. Kepler-452b, which was discovered by the Kepler spacecraft in 2015 and is about 1,400 light-years from us, is particularly interesting. It is 50 percent bigger than our planet, so you would weigh more than you do on the planet Earth, but otherwise, living there may not be so different from living on Earth.

Musk's proposed rocket system was originally called the Mars Colonial Transporter, but he renamed it the Interplanetary Transport System because, as he said, "This system really gives you freedom to go anywhere you want in the greater solar system." His long-term vision is to build a network that would connect the planets as the railroad connected American cities. Musk

It would take them only five seconds to zip to the moon, about an hour and a half to get to Mars, and a few days to reach Pluto. Rather than waiting ten years for a mission to the outer planets, we could receive new information about them from nanoships in a matter of days, and in this way we could observe the developments in the solar system very nearly in real time.

È stato allora che ho capito il significato magico del cerchio. Quando si è allontanati da una fila, è ancora possibile reinserirsi. La fila è una formazione aperta. Ma il cerchio si richiude e non ci si può tornare. Non per caso i pianeti si muovono in cerchio, e la pietra che se ne stacca si allontana inesorabilmente, spinta dalla forza centrifuga. Simile a un meteorite staccatosi da un pianeta, io sono precipitato dal cerchio e non ho finito, ancora oggi, di cadere.

The very existence of galaxies, stars, planets, and life itself derives from microscopic quantum uncertainty amplified by inflationary expansion.
