Interstellar Travel: Approaching Light Speed

  • Interstellar Travel: Approaching Light Speed


    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.

    Interstellar Travel
    Interstellar travel is the term used for hypothetical crewed or uncrewed travel between stars or planetary systems. Interstellar travel will be much more difficult than interplanetary spaceflight; the distances between the planets in the Solar System are less than 30 astronomical units (AU)—whereas the distances between stars are typically hundreds of thousands of AU, and usually expressed in light-years. Because of the vastness of those distances, interstellar travel would require a high percentage of the speed of light; huge travel time, lasting from decades to millennia or longer; or a combination of both.

    The speeds required for interstellar travel in a human lifetime far exceed what current methods of spacecraft propulsion can provide. Even with a hypothetically perfectly efficient propulsion system, the kinetic energy corresponding to those speeds is enormous by today's standards of energy production. Moreover, collisions by the spacecraft with cosmic dust and gas can produce very dangerous effects both to passengers and the spacecraft itself.

    A number of strategies have been proposed to deal with these problems, ranging from giant arks that would carry entire societies and ecosystems, to microscopic space probes. Many different spacecraft propulsion systems have been proposed to give spacecraft the required speeds, including nuclear propulsion, beam-powered propulsion, and methods based on speculative physics.

    A Slower Speed of Light

  • Light Speed Travel


    The speed of light is more of a hot topic than ever nowadays. It is the speed at which photons travel in a vacuum- and is the fastest speed achievable within the universe. As creatures of exploration and innovation, understanding light speed has naturally led us on a quest to try and determine a method with which we can reach it, and eventually one day exceed it. Si-Fi fantasy or not, a galaxy of the Milky Way’s vastness would require such speeds to make exploring it somewhat of a possibility for a race such as humanity’s. But there are some drawbacks. The difficulty of developing light speed travel, or propulsion systems that could travel at a high percentage of it, is enormous- and may be impossible altogether. Furthermore, our current understanding of physics suggests that were you to travel at this immense speed, you would be making more of a sacrifice than you first anticipate, as light and time go hand in hand at the limit of possibility. Nonetheless, we are investing, investigating and innovating, and examining the skies and the stars, as we search for a way to travel at the ultimate speed of light…

  • Fastest way to reach Mars in 20 minutes at no cost - Connectome


    Derek Muller (Veritasium) asks Michio Kaku (Nov 4, 2015) about whether it is possible to do interstellar space travel and Michio Kaku explains different ways that we are deploying right now like booster rockets, nuclear rockets, antimatter rockets but all of these are very expensive and takes lots of time. But there is another way that humanity isn't taking seriously and that is connectome aka sending human consciousness into space on a laser beam and it can help us reach alpha centauri in just four years.

    You can also buy a book on connectome -

  • Can We Travel Faster Than Light? with Dr. Miguel Alcubierre


    Can humanity build an Alcubierre warp drive?
    Can we go faster than light?

    Dr. Miguel Alcubierre was inspired by Star Trek the Next Generation's example of warp drive faster than light technology on the starship Enterprise. In 1994 he wrote a paper on how we could bend and warp space and time to travel faster than light within the rules of Einstein's general relativity. NASA has and is currently exploring if it is possible to bend the fabric of space and achieve hyper fast space travel with the Eagle Works lab. John Michael Godier spoke with Dr. Miguel Alcubierre on the feasibility of the Alcubierre warp drive and if there has been any developments within physics, including the use of dark matter or dark energy, and anti-gravity, to be able to make this possible.

  • 3 Things Faster Than Light


    These 3 things go faster than the speed of light. How's that even possible?
    ↓Want more info?↓

    More about the experiment:
    Marissa Giustina’s research:

    Advanced scientific note about Doppler: If there is a light moving away from you at constant velocity in static flat (Minkowski) space-time, no matter how red it is, you will never conclude it is going faster than light. But, here I am discussing the conclusions one might come to if you mistakenly use Doppler in the context of the curved space-time of the universe (where there is expansion). Interpreting the huge redshift as a result of the doppler effect, could make one think that galaxies we see are moving away at speeds approaching light speed. And since what we are actually seeing is light from those galaxies from billions of years ago, and given that the universe is expanding, you might be tempted to say that they have since accelerated to faster than the speed of light. You might go further and say that there are more distant galaxies that we can't see which are moving away even faster. So you might conclude there are galaxies moving faster than light in the universe. But the redshift isn't from doppler and this acceleration of the expanding universe isn't actually causing a true increase in velocity.

    Sometimes astronomers do say there is a faster than light recession speed by pretending the expansion of the universe is causing distant galaxies to move away from each other at a corresponding velocity, but that's misleading. In general relativity, you can actually have an increase in space between objects without causing a corresponding increase in the relatives velocities of those objects.

  • Real Possibilities For Interstellar Travel!


    From special kinds of engines to new technologies that'll literally warp us across the galaxy, join me as I show you some real potential interstellar travel possibilities.
    7. How To Define Interstellar Travel
    You might think that the term interstellar travel means a lot of different things depending on your views of space and the various TV shows and movies that you've watched.
    Wikipedia defines it as such: Interstellar travel is the term used for crewed or uncrewed travel between stars or planetary systems.
    Notice how they say planetary systems and not traveling between the planets in our own solar system. Traveling from Earth to Mars, or even Earth to Pluto (still a planet!) is considered interplanetary travel. Whereas Interstellar Travel is the process of going beyond our own solar system, and doing it in a relatively easy amount of time.
    Which naturally brings us back to things like TV shows and movies where various sci-fi franchises have had their own style of Interstellar Travel. Whether it was the Lightspeed Drives in Star Wars, or the Warp Engines in Star Trek, they had ways to traverse massive star systems in minutes, or hours at the most depending on distance.
    This is something that humanity is still aiming to create, and right now...we're a long ways away. But, we're getting there, bit by bit. And do recall, at one point in time humanity was restricted in how it could fly. Planes were once just massive hot air balloons, and the idea of going to space on such a craft was ludicrous to say the least.
    So while we're not there yet, there are tons of industries and space entities trying to make these potential possibilities come true.
    6. The Breakthrough Starshot
    Believe it or not, one of the most likely candidates in regards to Interstellar Travel was announced as being developed in 2016. It's called the Breakthrough Starshot, and it's meant to use the Earth's own atmosphere to help power flight to the nearest star systems to Earth.
    How is that possible? Simple, we're going to power up some sails.
    To be clear, this is NOT a manned mission to the stars, it's quite literally a one-way trip, but it's an epic one considering how they're going to do it. According to the creator of the project, Yuri Milner, he plans to put into the orbit of the Earth massive light sails, which you've no doubt heard referenced in various sci-fi shows of certain kinds.
    Anyway, these sails are going to have special chips attached to them, and then once they're launched into orbit, they're going to be blasted by a laser that'll power them up. The laser (which will be fired from Earth which goes to show how powerful it'll need to be in order to reach space) will charge them up for two minutes, which is all they'll need in order to travel about 1/5 of the speed of light.
    To put that into a round number for you, that's about 60 million meters per second. So yeah, that's pretty fast.
    So what's the goal of these light sails? Well, much like the Voyager 1, it's meant to record data from the stars and planets that it passes. The team are so confident in these sails that they're planning to reach the Alpha Centauri system (which for the record is 4.3 light years away) and will use a special camcorder on the sails to get images in high resolutions and send them back to Earth (not unlike Voyager 1 and other probes and satellites) for us to study.
    Now, if you're wondering why these light sails haven't been launched's because they're not done. There's still many advances that need to be made before that becomes possible. HOWEVER, at present, the only limitations are the technologies that we have right now. Meaning that we don't need sci-fi tech to make it work, we just have to make what we got better.
    And should this work in this phase, the technology could be adapted to make it work with manned ships. It's just a matter of time and technology.
    5. The Energy Cost
    When talking about Interstellar Travel, it's important to note the things that are holding us back as well as the things that could push us forward in the field.
    Without a doubt, the biggest thing that is preventing us from making a reliable Interstellar Travel engine is energy. If you think about it, a spaceship isn't much different from a car. It has systems that make it run, and an engine that needs fuel in order to run. The hardest things for the early Mercury and Apollo missions was making sure that the engines that they built had enough power and speed to break through the atmosphere, which needs a certain velocity.
    So now, imagine trying to make a spaceship that is meant to go to other star systems, and potentially come back...all on one tank of gas.
    Not the easiest thing to do. Which is why ideas like the Light Sails are meant to be powered by other things other than raw fuel.

  • A Journey to the End of the Universe


    Could humans ever travel to other galaxies within their lifetime? The immense scale of the Universe seems to prohibit such voyages, after all the nearest galaxy is so far away that it takes light itself - the fastest thing in the Universe - 2.5 million years to complete the trip. Remarkably, there is a trick that might allow humans to accomplish this feat - join us today as we step onboard the constantly accelerating spaceship!

  • Can You Go the Speed of Light?


    Einstein's classic thought experiment involves sitting on a train travelling at the speed of light. If you hold a mirror in front of your face, will you see your reflection in a mirror? How could light from your face reach the mirror if the mirror is travelling away from you? But it would be a pretty spooky train if you couldn't see your reflection so Einstein felt this solution wasn't realistic. On the other hand if you could see your reflection, it would mean light was travelling at the speed of light inside the train. But that meant the same light observed from outside the train would be going twice the speed of light. This again seems inconsistent. So Einstein resolved that you must see your reflection but that light must travel at the same speed inside and outside the train. The only way this is possible is if space and time are perceived differently by observers inside and outside the train.

    The Alcubierre Warp Field and Anti Matter [2020]

    The Alcubierre warp field as described by Miguel Alcubierre would help us surpass the speed of light many times which means that if we had a ship that could go 10 times the speed of light, it would take only 153 days to reach Proxima Centauri.
    Much more reasonable I would say. But building a warp drive is not an easy task.

    Miguel Alcubierre is a theoretical physicist famous for the Warp Field theory.
    In May 1994 he published a paper titled “The Warp Drive: Hyper-fast travel within general relativity” however, his goal with this paper, contrary to popular belief had little to do with warp drives, it was to show that a distortion of space and time is indeed possible within the realms of general relativity, and therefore we could travel faster than the speed of light.

    Text at

    Music free version

    In this segment of the “How Fast Is It” video book we cover the speed of light. We start with the slow moving snail and work up through people, animals, birds, cars, aircraft and spaceships. Along the way we graph speeds on a space-time diagram. Following the history of land speed records, we cover the speed of sound and include its nature as a longitudinal wave and its speed in dry air. We then cover the Galilean transformations for converting speeds from one reference frame to another. We increase the velocities to the point where we see light traveling at different speeds as far as the Galilean transformations are concerned. We then show how Galileo tried and failed to measure the speed of light. Then we show how Antonio Louis Fizeau did measure the speed of light. We then cover wave interference and the Michelson Interferometer. And using the interferometer, we cover the Michelson-Morley experiment that showed that the speed of light was a constant.

  • Time Dilation - Einsteins Theory Of Relativity Explained!


    Time dilation and Einstein’s theory of relativity go hand in hand. Albert Einstein is the most popular physicist, as he formulated the theory of relativity, which gave the Energy mass equivalence formula and is directly related to time dilation. But what is time dilation? Time dilation and space time are interrelated. Einstein made one of the most important contributions to physics and had the concept of space time explained. A simple explanation of space time is that it is a mathematical model that fuses the three dimensions of space and the one dimension of time into a single four-dimensional continuum. But it is very important to understand that the general theory of relativity and the special theory of relativity are different. In this short animated video, we give a simple explanation of time dilation and Einstein’s theory of relativity and also explain how time slows down in a moving vehicle!
