simple.. there will be no life.
It will be dark.
While true it would be dark, don't tell the many thousands of organisms hanging around hydrothermal vents at the bottom of the oceans [where there is no light] that they aren't alive.
If light does not travel in a straight line, vision would not be accurate since objects will appear to be in different places. The reflected light that hits the eyes will bring images from different areas.
Light doesn't always travel in straight lines. It bends and changes direction for a number of reasons. The most common reason is refraction when light travels in transparent media of different density, as in lenses, or in the atmosphere, or as it passes from water to air.
The effect of curved light paths is that the object you see is not actually where you think it is. This makes spearing fish in shallow water very difficult, as the fish is not where it looks like it is.
Gravity also bends light, but the effect is negligible in normal life.
Black Holes are collapsed stars with gravity so strong that light they emit curves back into them, so you cannot see them - hence the name.
Technically, the answer to this is "no". Einstein's theory of relativity proves that light is curved by the force of gravity. However, the curvature is very slight over most of the vacuum of space, so it is usually safe to treat it as a straight line.
As a matter of fact, it doesn't always, especially here on Earth where it has to
travel through air.
Light curves as it makes its way through air. The effect is small, noticeable only
over long distances, but it's the reason why, within a few hundred miles of a large
mountain, its peak can occasionally be seen up in the sky. It's also the reason
that the stories of flying horses and magic carpets, and reports of palm trees seen
hanging in the air, come from places near harsh deserts, where the air is dry, the
temperature swings are extreme, and large vertical gradients of atmospheric
refractivity are common.
Light almost always curves gently downward as it travels through air, and the result
of that is to make distant objects appear to be higher than they actually are.
Whenever light doesn't travel in a straight line, things appear to be located in
the wrong direction. That's why the end of the straw that's down in the drink
looks as if it doesn't line up with the top end, and why you can still see the sun
above the horizon for several minutes after it has actually set, and why it looks
like your face is behind the mirror.
It's also the reason why the fish in the shallow creek are not where they appear
to be, and why you and I fail miserably when we try to catch one with our hands.
But fisher birds, bears, and spear fishermen very easily learn to adjust, and that's
exactly what we would do if the curvature of light were much greater. Our brains
would learn where things really are based on where they appear to be, and we'd
correct for it subconsciously, without ever thinking about it.
Yes, it is theorized that there are higher dimensions then the four we are familiar with. No, you cannot travel at the speed of light, no physical object that has mass can. However, that being said, you can, theoretically travel infinitely close to the speed of light which would, in turn, require an infinite amount of energy.
No. An eyeglass works by bending light (refraction) to change to focal point into something appropriate for whatever eye condition you have (nearsightedness, farsightedness, etc.). The reason that the light bends is that it obeys something known as Fermat's Theorem. Fermat's Theorem says that light takes the fastest travel path (it minimizes travel time, not travel distance) through any medium. Since the speed of light is different in every medium this means that the fastest path doesn't usually follow a straight line if we change mediums. Since light travels more slowly through glass than air, the path bends, hence the refraction, hence the ability of glasses to fix your eyes. Simply put eyeglasses work precisely because of these two properties: 1) Light has different speeds in different mediums 2) Light always minimizes its total travel time
If you travel along a line of longitude from the South Pole, you would travel directly northwards.
To travel at the speed of light you would have to BE light so i guess you would became an even brighter light The switch to turn on the lights will work but no light will come on as you are already at that speed
no. all lights travel at the same speed if its in the same medium. eg: lights travel with velocity, v= ( 3x10^8 m/s) in air. and it would be approximately 2x10^8 m/s in glass.
Light is a particle that acts like a wave and therefore does not travel in a straight line. light has nothing to do with gravity, the fourth dimension or the 'fabric' of space time.
I believe it might be because the light has nothing to reflect off of so it would travel in a straight line
If light did not travel in a straight line then the light would just bend around the body that is suppose to be making a shadow and no shadow would be observed. as there is a shadow cast by that body this proves that light does not bend and in fact travels in a straight line.

The only way to travel at the speed of light is to not have any mass.
Assuming the train continues moving at constant speed, the ball would travel at the same speed as the thrower.
Yes light can travel through prisms. At some points it would occur total internal reflection and at some points there would be refraction of light.
In a material of high refractive index, the speed of all colours is not the same, some travel faster than others, but all travel slower than light would in a vacuum.
If you travel along a line of longitude from the South Pole, you would travel directly northwards.
i have no clue
The speed of light doesn't travel at all. It just lays there, typicallyon a printed page in a book.If an object is traveling at the speed of light, however, then it's acompletely different story. Such an object would cover 1 quintillionmiles in only 170,108 years (rounded).
