A negative energy problem
The warp drive would require either negative mass — a theorized type of matter — or a ring of negative energy density to work . Physicists have never observed negative mass, so that leaves negative energy as the only option.
How do you warp gravity?
Can a warp drive go faster than the speed of light?
He used a different geometric approach to solve the equations of General Relativity, and by doing so, he found that a warp drive wouldn’t need to use negative energy. Lentz’s solution would allow the bubble to travel faster than the speed of light.
Is NASA building a warp drive?
According to Popular Mechanics, the NASA warp drive will expend a massive amount of energy that will “warp” (contract and twist) space time behind the spacecraft, which will create a space time “bubble.” This bubble, which will be created around the ship and curved behind it, will theoretically reduce the distance that ...
Is NASA working on a warp drive?
DARPA and NASA Scientists Accidentally Create Warp Bubble for Interstellar Travel. A Defense Advanced Research Projects Agency-funded research project at NASA’s Johnson Space Center may have accidentally discovered how to build a warp drive engine . The scientists published their findings in July.
Can humans warp spacetime?
You don’t have to be the size of a planet to do some space-time warping . Large objects such as the Sun and planets aren’t the only masses that warp the fabric of space-time. Anything with mass—including your body—bends this four-dimensional cosmic grid.
How realistic is warp?
Although it was originally a fictional idea, a 1994 paper by Miguel Alcubierre showed how “warp drive” is really possible within general relativity . By creating a warp bubble where space compressed in front of the ship and rarified behind it, warp travel would be possible, but would require negative mass/energy.
Are wormholes possible?
Einstein’s theory of general relativity mathematically predicts the existence of wormholes, but none have been discovered to date . A negative mass wormhole might be spotted by the way its gravity affects light that passes by.
Is Lightspeed possible?
Based on our current understanding of physics and the limits of the natural world, the answer, sadly, is no . According to Albert Einstein’s theory of special relativity, summarized by the famous equation E=mc 2 , the speed of light (c) is something like a cosmic speed limit that cannot be surpassed.
Is light faster than darkness?
Darkness travels at the speed of light . More accurately, darkness does not exist by itself as a unique physical entity, but is simply the absence of light. Any time you block out most of the light – for instance, by cupping your hands together – you get darkness.
Is a black hole faster than light?
To escape from within a black hole requires faster than light speeds , but according to Einstein’s theory of gravity, General Relativity, gravity is the distortion of space and time caused by the presence of mass.
Does gravity warp spacetime?
Gravity, Einstein asserted, is caused by a warping of space and time —or, in a language we physicists prefer, by a warping of spacetime. The Earth’s matter produces the warpage, and that warpage in turn is manifest by gravity’s inward tug, toward the Earth’s center.
How does gravity affect mass?
Gravitational forces are considered to be inherently linked to what we call ‘mass’. There is a gravitational force of attraction between every object in the universe. The size of the gravitational force is proportional to the masses of the objects and weakens as the distance between them increases .
Do astronauts age slower?
And for astronauts on the International Space Station, that means they get to age just a tiny bit slower than people on Earth . That’s because of time-dilation effects. First, time appears to move slower near massive objects because the object’s gravitational force bends space-time.
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.
Is time Travelling possible?
In Summary: Yes, time travel is indeed a real thing . But it’s not quite what you’ve probably seen in the movies. Under certain conditions, it is possible to experience time passing at a different rate than 1 second per second.
Is quantum drive possible?
Although this concept may be allowed by the currently accepted laws of physics, it remains unproven ; implementation would require a negative energy density, and possibly a better understanding of quantum gravity.
Who invented warp drive?
This controlled explosion is what generates the tremendous power required to warp space and travel faster than light. On Earth, warp drive was invented in 2063 by noted scientist Zefram Cochrane .
How fast is Star Trek warp speed?
Even considering the fastest “transwarp” (or “beyond warp”) speed achieved by the Enterprise, which is about 8,323 times light speed , according to “Star Trek: The Next Generation — Technical Manual,” a transgalactic voyage would take 24 years.
How fast is warp 5 in mph?
| Warp factor Calculated speed (c) Distance traveled in 24 hours (light years) | 5 125 0.342 | 6 216 0.591 | 7 343 0.939 | 8 512 1.402 |

Does gravity transcend time?
In general relativity, gravity and space-time are EXACTLY THE SAME THINGS BY DEFINITION. It is impossible, within general relativity, to separate gravitational fields from the fundamental properties of space-time.
Can time be stopped?
The simple answer is, “ Yes, it is possible to stop time . All you need to do is travel at light speed.” The practice is, admittedly, a bit more difficult. Addressing this issue requires a more thorough exposition on Special Relativity, the first of Einstein’s two Relativity Theories.
Can gravity bend light?
Gravity bends light
Light travels through spacetime, which can be warped and curved—so light should dip and curve in the presence of massive objects.
Did NASA discover a warp bubble?
A team of physicists has reported the accidental discovery of a real-world “warp bubble” whilst observing the structure of Casimir cavities – a small step towards building a potential warp drive.
Has warp drive been invented?
The first scientific realization of a functional warp drive, originally devised by physicist Miguel Alcubierre, came to light in 1994 . In his proposal, he suggested that general relativity would allow such a device, if ever built, to travel faster than the speed of light.
