obviously you would see darkness, as long as your not blind yes it still considered to be seeing something even though a blind man would see the same thing, or does he?

Is a star dead by the time its light gets to earth?
No. This is a common misconception. Most of the stars we see in the night sky are no more than a few hundred light years away. The closest star outside the solar system is Proxima Centauri, which is only 4.2 light years away. At such distances the light coming in from those stars left them no more than a few hundred years ago, only 4.2 years ago in the case of Proxima Centauri. No star in our galaxy is more than 75,000 light years away. Most stars last for billions of years, so 75,000 years for a star is not long at all. There are stars in other galaxies far enough away to have died by the time their light reaches us, but they are too far away for us to see them without a powerful telescope.
How did the light bulb change our lives?
The light bulb changed our lives a lot. If Thomas Edison (inventor of the light bulb) hadn't invented it, then we would all be stumbling in the dark. And since the time he created it, everybody is using it. Look around. Look in your house, and in your neiborhood houses. And in the schools. Do you see light bulbs? See, if you didn't have the light bulb, you're a step away from a blind mole.actually humphry davy made it , thomas made it better and more useful so he improved it but did not make the real thing :)
What does the blue shift mean in regard to stars and galaxies?
Light is a spectrum. On one end it is red and the other blue. We see light in this spectrum as waves and if it is blue, the object is coming toward us. If the waves are red than it is moving away. The frequency of these waves tell us how fast and object is moving toward or away from us.
Can you see satellites in the mesosphere?
If your lucky. Yes you can see them but it would be pretty hard to see. because of all the gasses and because of how far away you are and its hard anyways to see curtain things with the naked eye. xoxo, Jenna
What are advantages of visible light?
The advantage of visible light is that you can see it. Also, because our eyes are sensitive to light you can see colors. Violet has the shortest wavelength and red has the longest. Visible light is the only EM waves that you can see.
The hubble telescope can see quasars that are 58,690,000,000,000,000,000 miles away. How long does it take light to reach earth from these quasars?
12.8 billion light years away.
How long does it take light to get to earth from most individual stars you see at night?
that question is impossible to answer without a specific star because they are all in completely different places. Most of the stars you can see as individual stars are less than a couple of thousand light years away. The nearest are just 4 light years away.
Does it sometimes take millions of years for starlight to reach earth?
Not for the stars you can see without a telescope. All of the stars you see at night are within a few hundred light years of Earth, so it does not take the light more than a few hundred years to reach us. There are stars in other galaxies that are millions or even billions of light years away. That light does take millions to billions of years to reach us, though the stars are too far away for us to thee them individually.
How long would it take to see a star explode on earth?
That depends on how far away the star is. If the exploding star is 1,000 light years away we would see the supernova 1,000 years later. If it is 2,000 light years away we would see it 2,000 years later.
How long does it take the human eye to see an object a trillion miles away?
Light from an object a trillion miles away (10 to the power of 12) will take around 0.17 years to get to the observer or 62 days.
What is the meaning in the song Long as you can see the light?
well, it could mean a lot of different things. my take on it is that it may have something to do with drug usage. he knows not to get lost, as long as he can remember that and not get carried away.... as long as, he can see the light...
What chases away hantu raya?
When you see "hantu haya" take out you all your cloth and naked. If it real hantu raya, it will ran away because it shy to see your XXX .
Is it possible to look into the past?
yes it is, we are all energy(light). whwen we observe things that are light years away, we are actually looking at the image displayed years ago. so if we figuere a way to reverse and see earth from light years away, we would be able to see the earth at that same time in the past.
How you see light?
You see light when your vision receptors take in the electromagnetic wavelengths and your brain processes the light, as well as color.
Are all the stars in the night sky you can see only from the Andromeda galaxy?
No. The only stars you can see are within our own galaxy, the Milky Way. The Andromeda Galaxy is a faint smudge of light 2.5 million light years away, beneath the constellation Cassiopeia. Most of the stars you can see are within a couple hundred light years. A few, like Deneb, are several thousand light years away--and just extremely bright.
What kind of shift would you see if a light was moving away from you?
redshift
Why you see the light before you hear the sound during rocket launch?
Light travels much faster than sound. The light from the launch reaches you almost instantly, but if you are a few miles away the sound will take several seconds to reach you.
