Although the metric proposed by Alcubierre is consistent with the Einstein field equations, construction of such a drive is not necessarily possible. The proposed mechanism of the Alcubierre drive implies a negative energy density and therefore requires exotic matter or manipulation of dark energy.
How fast would an Alcubierre drive go?
Should not violate space time continuum. Very Theoretically: A warp(Alcubierre) drive can go ~10c without being affected by time dilation. A space vessel can go up to but not as fast as the speed of light.
Is NASA really working on a warp drive?
NASA is obviously still working out the kinks of their warp drive, but perhaps it’s only a matter of time before at least neighboring star systems, like Proxima Centauri, will be in reach for human crews. Until then, we can only look at the furthest stars using our telescopes.
How does an Alcubierre warp drive work?
Alcubierre’s warp drive would work by creating a bubble of flat spacetime around the spaceship and curving spacetime around that bubble to reduce distances. The warp drive would require either negative mass – a theorized type of matter – or a ring of negative energy density to work.
Will Lightspeed ever be possible?
So will it ever be possible for us to travel at light speed? Based on our current understanding of physics and the limits of the natural world, the answer, sadly, is no. … So, light-speed travel and faster-than-light travel are physical impossibilities, especially for anything with mass, such as spacecraft and humans.
Does Alcubierre drive cause time dilation?
This means that even though the coordinate acceleration can be an arbitrary function of time, the proper acceleration along the spaceship’s path will always be zero. So the Drive itself causes no time dilation for the occupants of the ‘warp field bubble’.
How much energy would a warp drive need?
Creating a warp bubble for a 656-foot-wide spacecraft traveling at the speed of light requires roughly 100 times the energy contained in the mass of Jupiter, said Lentz. That’s about 30 orders of magnitude higher than the power of modern nuclear reactors.
Has warp drive been invented?
On Earth, warp drive was invented in 2063 by noted scientist Zefram Cochrane.
Is warp drive faster than hyperdrive?
If this is a Star Trek vs. Star Wars question, then hyperdrive is faster than warp drive. It took a warp drive ship 7 years and a lot of cheating to cross a quarter of the galaxy. Hyperdrive ships routinely cross the entire galaxy in a matter of days.
Who invented warp drive?
As any avid Star Trek fan can tell you, the eccentric physicist Zefram Cochrane invented the warp-drive engine in the year 2063. It wasn’t easy. As any avid Star Trek fan can tell you, the eccentric physicist Zefram Cochrane invented the warp-drive engine in the year 2063.
Can we achieve interstellar travel?
The truth is that interstellar travel and exploration is technically possible. There’s no law of physics that outright forbids it. But that doesn’t necessarily make it easy, and it certainly doesn’t mean we’ll achieve it in our lifetimes, let alone this century. Interstellar space travel is a real pain in the neck.
What is a warp drive and how does it work?
Warp drive was a technology that allowed space travel at faster-than-light speeds. It worked by generating warp fields to form a subspace bubble that enveloped the starship, distorting the local spacetime continuum and moving the starship at velocities that could greatly exceed the speed of light.
Are wormholes possible?
Wormholes are consistent with the general theory of relativity, but whether wormholes actually exist remains to be seen. … Theoretically, a wormhole might connect extremely long distances such as a billion light years, or short distances such as a few meters, or different points in time, or even different universes.
Does warp drive violate causality?
Warp drives would not necessarily violate causality, either — although the possibility has been raised that they could help create closed timelike curves (CTCs). Thus they could visit the past — but only as far back as the moment that the CTC was created, so it would be strongly limited.
Can humans travel to another galaxy?
The technology required to travel between galaxies is far beyond humanity’s present capabilities, and currently only the subject of speculation, hypothesis, and science fiction. However, theoretically speaking, there is nothing to conclusively indicate that intergalactic travel is impossible.
Can neutrinos travel faster than light?
Five different teams of physicists have now independently verified that elusive subatomic particles called neutrinos do not travel faster than light.
How fast can a human go without dying?
This is a well documented field, and the average maximum survivable g-force is about 16g (157m/s) sustained for 1 minute. However this limit depends on the individual, whether the acceleration is applied to one’s entire body or just individual parts and the time in which the acceleration is endured over.
What is a warp bubble?
A warp bubble is a kind of loophole that could theoretically help spacecraft travel faster than light.
How do you prevent time dilation?
Time dilation cannot be avoided, because it is an observational appearance to the observer only who is watching the moving objects. It will have no physical effects on the object being observered. Even if you exceeded the assumed universal speed limit.
Why is there no time dilation in Star Trek?
The ship itself moves at sublight speed inside the warp bubble. That’s why you generally don’t see a time dilation effect due to warp speed travel. If Star Trek ships traveled FTL using thrust based propulsion, then you would regularly see a relative time dilation effect.
How long would it take to get to Alpha Centauri at Warp 9?
Warp factor | Calculated speed (c) | Travel time from Earth to Alpha Centauri |
---|---|---|
8 | 512 | 3.09 days |
9 | 729 | 52.07 hours |
10 | 1000 | 37.96 hours |
11 | 1331 | 28.52 hours |
What is actually warped by a warp drive?
Physics has scoffed at the idea of a real warp drive because it suggests travel faster than light. However, as the drive’s name suggests, such an engine did not push the spacecraft faster than the speed of light; instead, it merely warped space-time in a way that allowed for using a shortcut.
Are warp gates possible?
Warp Drive May Be More Feasible Than Thought, Scientists Say. … Now physicists say that adjustments can be made to the proposed warp drive that would enable it to run on significantly less energy, potentially bringing the idea back from the realm of science fiction into science.
How long would it take to get to Alpha Centauri at warp speed?
If you were able to travel to Alpha Centauri, roughly 4.25 light years away, at 99.9 percent the speed of light, you’d be able to see the time dilation more clearly. The trip would seem, from the perspective of an observer on Earth, to take a little more than 4.25 years.
Is warp speed faster than light speed?
A warp drive is a device that distorts the shape of the space-time continuum. A spacecraft equipped with a warp drive may travel at speeds greater than that of light by many orders of magnitude.
Why is it called Warp Drive?
Warp technology, as the name implies, ‘warps space’ in effect bringing a destination closer by bending space rather than the traditional ‘thruster’ means of propelling a spacecraft at high speeds.
How fast is the Millennium Falcon in warp?
Millennium Falcon | |
---|---|
Maximum speed | 1050 km/h (652 mph; maximum earth-like atmospheric speed) 75 MGLT (megalight per hour; subluminal speed) 0.5 HCR Blackmarket Drive (hyperdrive class rating; superluminal speed) 10.0 HCR Stock Back-up Drive |
How fast is Stargate hyperdrive?
The hyperdrives on a standard Ha’tak are capable of reaching speeds of up to 32,000 times the speed of light, but due to the far-flung nature of the Goa’uld Empire a Goa’uld homeworld had to be within less than a year’s reach of a planet designated for conquest.
How did the Klingons get warp drive?
However, according to the manual for Star Trek: Klingon Academy, the Klingons acquired warp drive much later (14th century AD), from the Hur’q during their conquest of Qo’noS (see below).
How long would it take to travel 70000 light years at Warp 9?
In Star Trek: Voyager, it is stated that it will take 75 years to travel 70,000 light years to reach Federation space. It is stated that the Voyager can sustain a maximum crusing speed of warp 9.975.
Why is warp 10 Impossible?
You can’t go faster than warp 10 because it is infinite velocity where you occupy all points in the universe at the same time. In TOS when they did so, it was on the old warp scsle where warp 14 is not warp 9 on the new scale. In Voyager, they discovered a new forn of dilithium that remained stable at transwarp speeds.
Is a Bussard ramjet possible?
Heppenheimer analyzed Bussard’s original suggestion of fusing protons, but found the Bremsstrahlung losses from compressing protons to fusion densities was greater than the power that could be produced by a factor of about 1 billion, thus indicating that the proposed version of the Bussard ramjet was infeasible.
How close is the closest habitable planet?
Dubbed Proxima b, the exoplanet is not only the closest exoplanet to Earth – its host star is located over 4.24 light-years away – it was also considered the most promising place to look for signs of extraterrestrial life.
Is Mars Habitable?
The habitability of Mars is limited by its small size, according to new research by Washington University in St. Louis planetary scientists.
Is warp 1 the speed of light?
The speed of light in a vacuum is about 186,282 miles per second (299,792 kilometers per second). In “Star Trek,” a warp factor of 1 is light speed, and a warp factor of 9.9 is more than 2,000 times greater than light speed.
Is warp drive copyrighted?
Warp drives first appeared in science-fiction back in the early nineteen-thirties. As a result warp drives are neither copyright nor trademarked as belonging to Star Trek. Impulse drives is a term coined in the Star Trek franchise. So it may be trademarked by them.
What is warp drive Quora?
Matter or energy is capable of warping or curving the spacetime fabric around itself. It is this quality of the spacetime fabric that gave rise to the possibility of creating a warp drive in which the spacetime is expanded behind the spacecraft and contracted in front of it.
