Sentences with phrase «distant at light speed»

On those nights, one could contemplate the scene dimensionally: there's the moon, less than two seconds distant at light speed, and behind it the locus of all galactic motion beckons mysteriously, more than a trillion times farther away.

Not exact matches

If we now consider the number of the stars (15,000 x 106 visible to the optical telescope alone) you will understand how it is possible to say, cosmically speaking, that we are enveloped in a sort of monstrous gas formed of molecules as heavy as the Sun moving at distances from each other so great that they have to be reckoned in light - years (bearing in mind that light travels at a speed of 186,000 miles per second, and that we are only 8 light - minutes distant from the sun)-- a gas made of stars!

Cosmology is similar: Because light travels at a finite speed, looking at distant light sources is literally looking back in time.

ANOTHER LOOKING GLASS In science fiction movies like Stargate and Contact, wormholes connect distant points in the universe, allowing people to travel from one spot to another in far less time than the hundreds or millions of years required to make the trip at the speed of light, the greatest conventional velocity.

Emitted in a distant galaxy when multicellular life was just beginning to populate Earth, the waves traveled at the speed of light for more than a billion years to at last wash over our planet last September, taking just seven milliseconds to traverse the distance between LIGO's twin listening stations in Louisiana and Washington State.

Measurements based on exploding stars suggest that distant galaxies are speeding away from each other at 73 kilometers per second for each megaparsec (about 3.3 million light - years) of space between them.

In the recent science fiction film Passengers, a huge spaceship flies at half the speed of light on a 120 - year - long journey toward the distant planet Homestead II, where its 5000 passengers are to set up a new home.

Only when we look at galaxies billions of light - years away, collecting the light they emitted billions of years ago, can we see that the most distant galaxies are moving more slowly than we would expect from observations of nearby galaxies, an indication that the universe has since sped up.

Because spacetime is being increasingly pulled apart, much of the distant universe will not affect the black hole at all, since that energy can't travel faster than the speed of light.

Gravity waves, emitted by black holes that collided far away and in the distant past, are now reaching Earth.29 From their beginning, they orbited their mutual center of gravity, each sending out — at the speed of light — one gravity wave per orbit.

Astronomers using the National Science Foundation's Very Long Baseline Array (VLBA) have discovered jets of plasma blasted from the cores of distant galaxies at speeds within one - tenth of one percent of the speed of light, placing these plasma jets among the fastest objects yet seen in the Universe.

That's when a Swiss astronomer named Fritz Zwicky determined the speed at which a distant cluster of galaxies revolved was an indication that they contained much more mass than observable light from them suggested.

Astronomers have calculated how fast a distant supermassive black hole rotates, clocking it at nearly half the speed of light.

where are the observations that show distant galaxies shrinking in our fireld of view which must be the case if they are moving away from us at near light speed?
