A new study has discovered a powerful force that is now driving evolution on Earth.

The future of space travel: Faster than the speed of light!

The future of space travel will need to advance and change dramatically to allow humanity to expand to the far reaches of, not only our own galaxy but far beyond to the mere edges of the universe (if there is an edge). Clearly, setting home on planets such as Mars becomes an obvious progressive strategy, but if humanity wanted to travel throughout interstellar space something special will need to be thought of. Currently, there are many ideas that seem to theoretically support the constraint illuminated from the laws of physics. Some of these ideas include travelling faster than light travelAlcubierre drive, artificial black hole and manipulating wormholes.
Let us place our focus on the conceptual theory of travelling faster than light travel. Travelling faster than light is physically impossible. Moreover, this speculated theory primarily is hammered with the constraint of special relativity, travelling faster than the speed of light essentially permits travelling backwards in time. Proposed mechanisms for travelling faster than the speed of light within the theory of general relativity require the existence of exotic matter, which the conflict sceptical notion defers the advances of producing sufficient quantity.  

Travelling at the speed of light is still not fast enough, this is why there is a massive need for scientific and technological advancements within this area of study. For example, light travels at 186,282 miles per second (299,792 kilometres per second) in a vacuum. In miles per hour,  light travels about 670,616,629 mph. Now, the closest galaxy to the Milky Way is Canis Major Dwarf Galaxy, around 236,000,000,000,000,000 km (25,000 light-years) away from the sun. 

So, what is a light-year in simple terms?

'A light-year is a unit of distance. It is the distance that light can travel in one year. Light moves at a velocity of about 300,000 kilometres (km) each second. So in one year, it can travel about 10 trillion km.

How many human years is a light-year?

'So there are 60 seconds in one minute, 60 minutes in one hour, 24 hours in a day, and approximately 365 days per year. We multiply all this together and we get this number (5,865,696,000,000). Therefore, a light-year is approximately 5.9 trillion miles.'

What if we could travel at the speed of light?

If we put this in perspective and let us say that we are to travel to Canis Major Dwarf Galaxy, it would take us travelling at the speed of light 25,000 years to reach our destination. It would take many generations before humanity even though about stepping foot onto a nascent habitable planet, and this would need to be set at a constant speed of travelling at the speed of light.

Just maybe Canis Major Dwarf Galaxy is out of our reach, so let's look at the nearest habitable planet in our own galaxy. On August 24th, 2016, astronomers announced the discovery of a rocky planet in the habitable zone of Proxima Centauri, the closest star to Earth. Proxima b, the planet has a mass 1.3 times of Earth and roughly has an orbital period of 11.2 Earth days. Proxima b is roughly 24.93 trillion miles away from our sun. This is an immense distance, but with a space shuttle and its enthusiasm to travel at the speed of light this distance could be concurred in just only 4.22 years.

As elaborated, the frustration regarding space travel is currently limited, not only due to our slow advancements in technology and the scientific enterprise but also due to our own biological limitations. Travelling at the speed of light would add unbelievable strain to the human body, it just may not be physically possible.

However, humanity has achieved so much working as individuals. Imagine a united international space agency funded by all countries collaboratively working together, Just think of the advancements and the achievements that would be created. Maybe a communal aggressive approach to concurring the limitations is the next step in space exploration.
