How Can We Travel at the Speed of Light


Travel at the Speed of Light

Have you ever wonder what is like to be traveling at the Speed of Light and most importantly how can we travel at the speed of light.

The speed of light in a vacuum is 186,282 miles per second (299,792 kilometers per second), and in theory, nothing can move faster than light.

Early scientists, unable to observe light's motion, though it must move immediately. Over time, however, measures of the motion of these wave-like particles became more and more accurate.

Albert Einstein's special theory of relativity says that photons or particles of light move at a constant speed of 670,616,629 miles per hour. As far as we know, nothing can travel faster than this.

But over the universe, particles are frequently accelerated to 99.99 percent the speed of light. Here are three different ways this acceleration can happen, according to NASA.

There are so many ways/methods to achieve Speed of Light at least in theory and we gonna take a took at those theories for achieving Speed of Light.

Is the speed of light constant?

Light travels in waves, and, similar to sound, can be reduced depending on what it is traveling through.

Light is reduced down in natural media such as air, water, and glass. The rate by which it is slowed is called the refractive index of the medium and is usually greater than one. When people talk about "the speed of light" in a general context, they usually mean the speed of light in a vacuum.

How Can We Travel at the Speed of Light

According to Einstein's general theory of relativity, as an object goes faster, its mass rises, while its length contracts. At the speed of light, such an object has an infinite mass, while its length is 0 — an impossibility. Therefore, no object can approach the speed of light, the theory goes.

That doesn't hold theorists from offering creative and competing ideas. Maybe in future generations, people will travel between stars the way we travel between cities nowadays.

Electromagnetic Fields

One of the most basic ideas that particles are accelerated to near light-speed is via the power of electromagnetic fields. These are made up of two components as the name implies electric and magnetic fields.

In principle, electromagnetic fields accelerate charged particles because the particles feel a force in an electromagnetic field that drives them along, similar to how gravity pulls at objects with mass. In the right conditions, electromagnetic fields can accelerate particles at near-light-speed. 

Magnetic Explosions 

Space is loaded with magnetic fields, some of which become entangled with one another. When this happens, the growing tension between the crossing field lines can cause them to explosively snap in a process known as magnetic reconnection.

Those fast particles also create a variety of side-effects near planets. Magnetic reconnection occurs close to us at points where the Sun’s magnetic field pushes against Earth’s magnetosphere its shielding magnetic environment.

When magnetic reconnection occurs on the side of Earth facing away from the Sun, the particles can be thrown into Earth’s upper atmosphere where they spark the auroras. Magnetic reconnection is also thought to be tied around other planets like Jupiter and Saturn, though in somewhat different ways.

Wave-Particle Interactions


Wave-particle interactions allow collision-free energy transfer in space plasma. 

The motion of these charged plasma particles is controlled by electromagnetic fields.

Particles can be accelerated to near light-speed via interactions with electromagnetic waves. When electromagnetic waves collide, their fields can become compressed. Any charged particles caught in the middle of the waves may start accelerating as they bounce back and forth between them.
