Anything with a non-zero mass can never reach c (speed of light in a vacuum). Anything with a zero mass can only travel at c (speed of light in a vacuum). Photons, the particles of light, have zero mass.
That said things with a non-zero mass can travel faster than the speed of things with a zero mass, when they are traveling in a medium (e.g. air, water, glass, diamond). However when they do so they emit Cherenkov Radiation (usually a blue to violet glow) in their direction of travel. This is very loosely the light equivalent of the sonic boom shockwave when something travels faster than the speed of sound in a medium. This radiation eventually slows them down.

Can the speed of light be measured accurately by the naked eye?
No, the speed of light cannot be accurately measured by the naked eye. While humans can observe the effects of light, such as seeing a flash or a distant object, our perception is not precise enough to measure the speed of light. Accurate measurements require specialized equipment, such as lasers and high-speed cameras, to capture and analyze light's behavior.
Why is 12000 lunar orbits the speed of light?
The speed of light is approximately 299,792 kilometers per second. The number of lunar orbits required to cover this distance would be 12000 because the circumference of the Moon's orbit around the Earth is about 10,000 kilometers. Multiplying this by 12000 gives an approximate value close to the speed of light.
Is it light speed or the speed of light?
speed of light I think well it sounds right:)
Is it possible to travel at the speed of light in water?
No, it is not possible to travel at the speed of light in water. Light travels at a slower speed in water compared to its speed in a vacuum, which is about 299,792 kilometers per second. The speed of light in water is approximately 225,000 kilometers per second.
Is the speed of sound as speed of light?
The speed of light is much greater than the speed of sound.
Can Humans Travel at speed of light with no harm on earth?
No.
What travels faster the speed of light or the speed of sound?
The speed of light is nearly a million times faster than the speed of sound.The speed of light is roughly 882 thousand times the speed of sound.-- Sound takes about 4.7 seconds to cover 1 mile.-- Light takes about 0.0000054 second to cover 1 mile.-- In the time it takes sound to travel one mile, light travels 881,741 miles .
Is it possible to travel at light speed for humans?
No. It has been stated that the speed of light can be approached, but people think it would rip a hole in the fabric of time if it happened.
Is it possible for humans to travel at the speed of light in outer space?
Speed of light is possible within a sphere.whereas controlled properties of the sphere can be introduced with technoligy in the year 2027.
In 1 hour how much kilometer cover?
Depends on your average speed. Distance = Speed*Time. If travelling at the speed of light, 1.08 billion kilometres. If at the speed of a garden snail, 0.05 kilometers.
Who was known for Speed of Light?
well this might sound crazy but the person/people who actually went at the speed of light is aliens in ufos because there way more complex than us humans so they are able to surpass us in speed
How long would it take to go 9.461 light years at average rocketship speed?
The maximum speed of the shuttle is 17,500 mphTherefore to cover 9.461 light years would take about 36,000 years
Why is light measured in distance and not in time?
-- The distance that light travels in some amount of time is expressed in units of distance. -- The time that it takes light to cover some amount of distance is expressed in units of time. -- The speed of light is expressed in units of speed . . . distance/time
Why is 12000 lunar orbits the speed of light?
The speed of light is approximately 299,792 kilometers per second. The number of lunar orbits required to cover this distance would be 12000 because the circumference of the Moon's orbit around the Earth is about 10,000 kilometers. Multiplying this by 12000 gives an approximate value close to the speed of light.
What object visible to humans travels the fastest and carries the most energy?
Light is the fastest object visible to humans, traveling at a speed of about 300,000 kilometers per second. Light also carries the most energy due to its high frequency and the equation E=mc^2, where energy is directly related to mass and the speed of light squared.
Is it the speed of light or light speed?
Is what the speed of light or light speed.ANSWER300,000 km/s
How far can we travel in terms of lightyear time travel?
As of now, humans can't travel through time or cover distances in lightyears. The concept of time travel and traveling vast distances in space at the speed of light is currently only theoretical and not achievable with our current technology.
