According to Einstein's physics, it would require an infinite amount of energy to accelerate a mass to the speed of light. Unless we invent warp drive, it ain't gonna happen. ================================== My high school physics teacher explained that it's like pushing wagon up a hill. As you get closer to the speed of light, the wagon becomes a car. As you get even closer to the speed of light, the car becomes a truck, becomes a bus, etc.
E=mc^2
Mass grows as you approach the speed of light. Therefore, more energy is required to move the ever increasing mass.

What did the black hole swallow?
anything it can reach that cant travel even faster than the speed of light. Absolutly everything.
What if the speed of light traveled at the speed of sound?
You cant run with that speed. There will be no problem if you can.
How do you make liquid light?
you cant. you can create a liquid that produces light, but because "light" is the photons from an object entering your eye, to create this liquid light ie liquid photons, the photons wouldnt leave the liquid and thus enter your eye.
Why don't you a rainbow during a thunderstorm?
As during a thunder storm there is very little light from the sun. so the light cant travel through the rain drops. thus making it impossible to have a rainbow
Why is their no delay between turning on a light bulb and seeing the light emits?
Our eyes cant perceive motion faster than 1/10 of a second and light can travel about 10,000m in 1/10seconds. Since a normal room is on an average 7m x 7m, there is no observable delay in between turning on a light and seeing the emitted light.
Why cant you travel at light speed?
Because we are just NOT that fast (also your body mass would be torn apart by the friction) As any massive object approaches the speed of light it proceeds to radiate gravitational waves. Therefore whatever energy goes into accelerating the object is quickly radiated away so there is no net increase in speed.
Why cant a clock travel at constant velocity?
Because volcity includes the direction of the object, and a clock can only measure speed.
What can light travel through that sound cant travel through?
light can travel through a vacuum whereas sound cant
How does how does light travel through opaque material?
it cant travel through light.
What is a material that light can't travel through?
light cant travel through opague materials, or anything you cant see through.
What is special about the speed of light?
you cant see it
How does light travel from one point to another?
In straight lines (well, "geodesic" might be a better term), and at the speed of light in the medium they're in.
Can light and sound travel through space?
light can but sound cant as there is no air
Why cant light travel through objects?
There are some objects through which light can travel, others it cannot. Light is a part of the electromagnetic spectrum and each part has a certain energy level. The energy required to travel through an object varies with the make up of that substance. The property an object has for allowing the passage of electromagnetic radiation to pass is called its transparency. An object may not allow light to pass but allow x-rays to pass because x-rays have more energy than light. There fore human flesh, for instance, is opaque to light but transparent to x-rays. There are other things involved but this is a simplified explanation.
Why cant the speed of light be exceeded?
In our Universe, any attempt to exceed the speed of light, as viewed in any frame, by a particle with mass, will be defeated by the laws of the Universe we happen to live in. Whether or not we like that fact is irrelevent: that's the laws of this Universe. It arises from the fact that an object getting close to the speed of light will get more and more massive as it gets closer and closer. Because of that, it will become harder and harder to make it go faster, as it takes more energy to accelerate an object with more mass.
Can you weigh light?
I would say that we can't weight light because whether heavy or light. if we weight any substance,if we pass light on that object the mass of that object will be constant so we cant measure light
Why does a shadow not form behind an opaque object?
because light passes through, and you cant have a shadow with light on now can you?
