Two recent papers – one by Alexey Bobrick and Gianni Martire and another by Erik Lentz – provide solutions that seem to bring warp drives closer to reality. In 1999, physicist Chris Van Den Broeck showed that expanding the volume inside the bubble but keeping the surface area constant would reduce the energy requirements significantly, to just about the mass of the Sun. A significant improvement, but still far beyond all practical possibilities. This 2–dimensional representation shows how positive mass curves spacetime and negative mass curves spacetime in an opposite direction . I don’t know if NASA can travel faster than light but I’m sure they can work harder than any of us. Wormholes are specific structures in the universe connecting two distinct points in space forming a passage that creates shortcuts for long space travel.
- Finally, equipment issues, including a loose cable, were discovered as likely culprits, and the results were declared erroneous.
- Since an object has infinite kinetic energy as it approaches the speed of light, it therefore also has infinite mass.
- Similar to a hyperdrive, coordinates must be calculated to ensure a safe jump; the longer the desired travel distance, the more complex the calculation.
- The 1,800-tonne OPERA detector is a complex array of electronics and photographic emulsion plates, but the new result is simple—the neutrinos are arriving 60 nanoseconds faster than the speed of light allows.
- With a telescope at just the right distance from the Sun, we could use its gravity to enhance and magnify a potentially inhabited planet.
- However, several objections raised against the Alcubierre drive appear to rule out the possibility of actually using it in any practical fashion.
As Scientific American continues, this solution doesn’t include human passengers. Rather, it uses microchip-sized “starchips” buoyed by super-thin, reflective sails that catch photons. These starchips could potentially travel at 20% light speed, which doesn’t cover a lot of ground compared to “Star Trek’s” warp drive, but could still arrive at Alpha Centauri within 20 years. At the very least, such probes could help carry the dream of faster-than-light travel and space exploration. At present, Einstein-Rosen bridges and Alcubierre warp drives are the only two leads to not only travel faster than light but carry people along for the ride.
Why Is It Called Space
Seen in such works as Battlestar Galactica, a jump drive allows for instantaneous teleportation between two points. Similar to a hyperdrive, coordinates must be calculated to ensure a safe jump; the longer the desired travel distance, the more complex the calculation. In theory, there is no limit to how far a jump can take a ship, but an incorrect calculation may result in a catastrophic collision with a planet or space debris.
Spacetime Warp Propulsion
If we really want to get speculative, Olum suggests FTL travel would be possible if exotic concepts, like those that emerge from superstring theory, prove to be correct.

To answer the broader question in detail, we need to specify what we mean by the universe “expanding faster than the speed of light.” The universe is not a collection of galaxies sitting in space, all moving away from a central mount everest 2017 point. Instead, a more appropriate analogy is to think of the universe as a giant blob of dough with raisins spread throughout it (the raisins represent galaxies; the dough represents space). When the dough is placed in an oven, it begins to expand, or, more accurately, to stretch, keeping the same proportions as it had before but with all the distances between galaxies getting bigger as time goes on. As a consequence of their great speeds, these galaxies will likely not be visible to us forever; some of them are right now emitting their last bit of light that will ever be able to make it all the way across space and reach us . After that, we will observe them to freeze and fade, never to be seen again.
A Ship Equipped With An Alcubierre Warp Drive Could Ride The Wave And Accelerate To High Speeds Or Even Time Travel
For calibration, the equipment was taken to the Swiss Metrology Institute . In addition, highly stable cesium clocks were installed both at LNGS and CERN to cross-check GPS timing and to increase its precision. After OPERA found the superluminal result, the time calibration was rechecked both by a CERN engineer and the German Institute of Metrology . Time-of-flight was eventually measured to an accuracy of 10 nanoseconds.
However this is possible only theoretically if you take the universe as a flat sheet gets bent and creates a shortcut way to the long distances. This however doesn’t break the law of speed of light that no anything could travel faster than the speed of light. Something else that has been on my mind, i find it troubling to think that the speed of light is constant. Light moves away from you at the same speed no matter how fast you are traveling, so that is never possible to catch up to its edge. However if we take a source of light that is flipped on while me and you stand at its source and you begin to travel at half the speed of light at the same time the light source is flipped on, how does light stay at a constant speed for us both?
General relativity was developed after special relativity to include concepts like gravity. It maintains the principle that no object can accelerate to the speed of light in the reference frame of any coincident observer. However, it permits distortions in spacetime that allow an object to move faster than light from the point of view of a distant observer. One such distortion is the Alcubierre drive, which can be thought of as producing a ripple in spacetime that carries an object along with it.
After a certain distance, the object is moving faster than the speed of light. At warp 1, the mass becomes infinite just like the energy required to move it. This is why according to one of the two pillars of our science , it is impossible to exceed the speed of light. The relationship between the energy and the mass, means that the kinetic energy of an object will increase its mass.
But it actually worked, and served as a predecessor to fiber optics. Lentz’s proposition takes into account Einstein’s relativity equations and formulates a way to travel faster than light without any exotic physics. After years of theorizing about traveling faster than light, Dr. Lentz’s hypothesis brings us a little close to a machine capable of traveling at high velocity.
