Why can't you go faster than light?

One of the most counterintuitive facts of our universe is that you can’t go faster than the speed of light. From this single observation arise all of the mind-bending behaviors of special relativity. But why is this so? In this in-depth video, Fermilab’s Dr. Don Lincoln explains the real reason that you can’t go faster than the speed of light. It will blow your mind.

Antimatter Propulsion - Ryan Weed, CEO of Positron Dynamics

Positron Dynamics is out to make space travel to distant stars a reality using antimatter. Antimatter is the most energy-dense material known. Positrons are the easiest form of antimatter to produce. With physics that is understood today, any hopes of traveling beyond the edge of the Solar System can only be realized with antimatter. To get there, our first steps lie in Earth’s orbit.

WHAT IF YOU TRAVELED AT THE SPEED OF LIGHT?

Subscribe! Because SMART IS THE NEW SEXY: https://goo.gl/JTfP6L How long does it take to get to… Space trips are one of the popular human dreams. Imagine that human techonolgies allow us to move with the speed of light 186,282 miles per second. Where can we go and how fast. And “Smart is the new sexy” have found that information. Do you want to know it? So, sit down and listen.

10 Objects Invented Just to Defy The Laws of Physics

Is interstellar travel doomed to remain in the realm of science fiction? Sticking to near future space propulsion only, how close can we get to the speed of light?

This video looks at the current spacecraft speed records with Apollo 10 holding the record for the fastest manned spacecraft, New Horizons probe for the fastest Earth escape velocity and the Helios probes for the fastest heliocentric velocity. But Solar Probe Plus will beat that when it launches in 2018. While Voyager 1 doesn't set any speed records, it was the first spacecraft to leave the solar system, so therefore the fastest solar system escape velocity by default.

For beating these speeds, this video explores what is possible in the near future only, so no antimatter, Alcubierre drives (warp), ramjets, etc... The EM drive is left out until it's proven with actual reproducible results in space.

Project Daedalus and the updated Project Icarus represent sound concepts for fusion spacecraft. IKAROS was the first successful demonstration of solar sail technology but hopefully the planetary society is not far behind with their LightSail cubsat (not covered in this video).

But what appears to have the most potential to reach the nearest star to our own, Proxima Centauri and it's newly discovered planet Proxima b is Breakthrough Starshot. Thousands of super lightweight laser sail nanocraft will be launched into space then the light beamer, a ground based laser array will propel these spacecraft to 20% light speed within minutes.
