is  it  possible  to  see  an aeroplane  coming  towards  you  at  speed  of  light?

Assuming you are standing still relative to the airplane, and the airplane is going at the exact speed of light... yes you would see it, but only as it colides into you.  if you are asking if you would see if before it hits you, then no.  Due to it's speed, all of the light coming off of it would not be able to outrun the plane.

No. There is no practical possibility. Humans can't travel at a speed equal to or greater than that of light.

Answer is yes.  By "seeing", what we really mean is our eyes receiving light either reflected or emitted from an object.  It doesn't matter how fast the object is moving, or if it's approaching or receeding - the speed of light is constant, therefore you will see it both coming and going.  That's one of the beautys of relativity - the speed of light is not relative to the object it's coming from, but instead is fixed and will measure the same speed for all observers in the universe, moving or not.

if i interpret your question correctly....i would think you are asking about the possibility of anti-gravity energy or "zero point" energy....well....there have been rumours going round about the ongoing research on such an energy source in laboratories in the States....in fact...it has been rumoured that the Germans were researching on it during the closing stages of WW2...basically physics entails that everything in the universe comes in pairs...like the presence of matter and anti-matter....so if there is a force like gravity...it is believed that anti-gravity should exist too...so for example, if a plane is fitted with an anti-gravity device...it will simply "float" in mid-air as anti-gravity repels the gravitational pull...maybe that's why sightings on UFOs cannot be completely dismissed...mmmmmmm

In geometrical optics with a pointlike sun the airplane would cast a shodow on the surface.\n\nBut: 1) The sun isn't pointlike but appears as a disc in the sky, so if light from diffent edges of the disc would cross under the plane ther would be no sharp shadow anymore, from a viewpoint on the surface the plane wouldn't cover the sun as whole\n\n2) Light is a wave, so geometic optics is not the whole story, there is refraction that bends the light into the shadow region. That's what you call "refill the void".

Yes..I have seen a many number of things both day and night..A massive object perhaps the size of a football field..with a smooth surface squared on all corners it was very massive and overwhelming..too big to be in the sky!! \nI have have witnessed a silver disc object above me in mid afternoon while fishing on my boat in the middle of the lake..it shot straight up into the sky with instant speed. Speed that we dont have here.\nAn elongated diamond light at night that graduated to having the intensity of a very bright spotlight...then dimming again to oginal intensity ..and shot off up into the sky..with incredible speed again...speed we dont have here.\nOrange glowing spheres in early evening...\nbackwards "c" shaped object in the daylight...\nthe list goes on..but..Yeah..I have seen many...Each time something does happen..it is like a new concept..it seems to keep opening the mind more and more..there are lots of things happening..it is not slowing down.

Well, when I drive the speed of light in my car... \n\nI think the person in front of you would see that they're on, but they wouldn't illuminate anything.

It's not a yes or no question.\n\nCan one travel faster than the speed of light?  No.\n\nCan objects be moving away from each other at a relative rate faster than the speed of light?  Yes.\n\nMeditate upon this, and you may become enlighted, or enspeeded, or something...

The previous answer is wrong. There is absolutely nothing stopping your reference frame travelling near (or even at) the speed of light. Even if you were travelling at 0.999999% the speed of light, you would still observe a light beam travelling past you at c. This speed is a constant because the speed of light does not depend on the velocity of the object emitting the radiation (see Maxwells equations).

As you approach the speed of light, your mass approached infinity... As your mass approaches infinity, it takes more force for you to accelerate... Therefore, I don't think it is possible for you to acchieve the speed of light...

Light travels faster than sound.

If you could travel at the speed of light in your space ship (which you can't) and turned on the headlights the light would travel away from your ship at the speed of light. The speed of light is invariant -- not affected by the speed of its source.

Peple I know you want the points, but can you please not just make up answers out of whole cloth like that?\n\n>>>>>Massive objects cannot go the speed of light.\n\nYeah, they can. They can't accellarate to the speed of light but they can be created at lightspeed and continue on.\n\n>>>>>> However if they could, no you could not see, becuase the light could not go furthur then the builbs at the front of your car\n\nNonsense. The speed of light is constant for all frames of reference. From the FOR of the bulbs the light would be seen travelling away from it at lightspeed. \n\n>>>> You'd be seeing the light go by your side.\n\nNo, you would not be seeing the light by your side. You would still be seeing all light in the universe travelling away form you or towards you at the speed of light, just as you do at your current velocity\n>>>>>The light would not shine out in front of you because you are going the same speed.\n\nIncorrect. Light always sines out in front at lightspeed in the observers FOR. It makes no difference if that FOR is stationary or lightspeed itself.\n\nYou quite obviously made that answer up.\n\nws, this question seems to get asked here every couple of days. You can go back and have a look and see it answered quite well several times.\n\nIn brief,\n\nLight is funny stuff. Light always travels at the same speed relative to you, it doens't matter how fast you travel. \n\nIf you are sitting still and a person is going past you at light speed you can both look at exactly the same light beam, and it will be travelling at lightspeed compared to both of you.\n\nIf you are going at lightspeed and turn on the headlights the light will move away fomr you at lightspeed. If it strikes something it will be refelected back at lightspeed. If someone is sitting completely still beside you he will also see that light move away form him at lightspeed, and get reflected back at lightspeed.\n\nIt's weird stuff light, it doesn't behave like anything else. The answer to any question that asks how fast light is moving towards you or away from you is always "lightspeed". It doesn’t matter what else we add to the question, the answer is always 'lightspeed".\n\nSo if the light leaves the bulbs at lightspeed and gets reflected back at lightspeed does that mean you could see?\n\nProbably not. \n\nAlthough light doesn't change speed relative to the observer it does change wavelength. The faster you travel towards a light source the bluer it will look. \n\nAny object that your headlights strike will reflect the light back to you at lightspeed, that's OK. But because you are travelling towards the object at lightspeed the light will be shifted way, way towards the blue end of the spectrum. It would all be ultraviolet an X-rays. The human eye simply can't see those wavelengths. So plenty of light would be reflected back, but it wouldn't be visible to you. As a result it would all look dark.\n\n\n>>>>> if the interior light inside your car was on at\n>>>>> the time would you see that?\n\nYes. Because both you and it are travelling at the same speed it woulnd't be red shifted at all. Similarly because you and the interior of the car are travelling at the same speed you would be able to see the light reflected off that just fine as well.\n\nEverything in the universe that is travelling as fast as you will look normal.Everything outside will appear black.

Again, the speed of light is a constant!  It does not increase in speed of the flashlight is moving really fast.  Its' like sound, sound goes 700mph in air at sea level.  If the plane goes faster than that it catches the sound, the sound doesn't go faster in front of the plane.  Same with light. Same with the opposite direction.

On 25th June 2006 at 05:07:26 am, exactly IST, look in the SW skies about 60 degrees. It helps if you get your watch to exactly IST from an internet time server or something. You will see a very bright flash of light.(Trust me this will really happen.)\n\nIf this looks anything like one of ur "UFO" sightings then it wasnt a UFO but sunlight reflecting off the solar panels of a Satellite.

According to Einsteinian theory, yes, you would see the light.  Einstein postulates that the speed of light is relative to the viewer.  If you were travelling at the speed of light and turned on a flashlight, the light traveling out of the flash light would be traveling away from you at the speed of light relative to you.

You would be in a different universe than you are now, because the laws of our universe say that a massive object can't go faster than the speed of light (or even as fast).\n\nAlso, if you changed the question to "...1 mile per hour less than the speed of light", you would have to specify "relative to ..." (what?)  And then you would have to say, what would happen as observed by (whom?).  In this question, relative to you, the headlights would turn on and you would be able to see things 186,000 miles ahead of you (as you measure miles) within 1 second (as you measured seconds) .  Relative to the observer that thought you were moving 1 mile per hour less than the speed of light - assuming you were moving toward the observer - you would get to him or her just a tiny fraction of a second after he/she saw the headlights turned on.  Your measurement of the speed of light would be consistent, but your measurments of time and distance would be very different.
