While
Alcubierre drives and wormholes cannot make us go faster than light
, we can use them to travel slower than light. This means that we could potentially still use negative energy sources like the Casimir effect to warp space in order to propel starships at subluminal speeds.
Is there anyway to travel faster than light?
Albert Einstein’s special theory of relativity famously dictates that
no known object can travel faster than the speed of light in vacuum
, which is 299,792 km/s. This speed limit makes it unlikely that humans will ever be able to send spacecraft to explore beyond our local area of the Milky Way.
Can we travel in past through wormholes?
“
You can go into the future or into the past using traversable wormholes
,” astrophysicist Eric Davis told LiveScience (opens in new tab). But it won’t be easy: “It would take a Herculean effort to turn a wormhole into a time machine.
Can we create a wormhole?
To create a wormhole on Earth, we’d first need a black hole
. This is problematic: creating a black hole just a centimetre across would require crushing a mass roughly equal to that of the Earth down to this tiny size. Plus, in the 1960s theorists showed that wormholes would be incredibly unstable.
Why is hyperspace not possible?
The speed limit
The first problem with a hyperspace drive is anything with mass – a starship, people, Wookiees – cannot go faster than the speed of light without fancy physics (which we’ll get into in a moment.) That’s a rule from Einstein’s Special Theory of Relativity.
Can a human survive a wormhole?
Humans could survive a trip through a wormhole
, but there’s a catch. There are drawbacks to this method — namely, such wormholes would be only microscopic, which means even the most hardcore exercise routine wouldn’t make humans thin enough for the trip.
What is the closest black hole to Earth?
In 2020, a team of astronomers with the European Southern Observatory (ESO) discovered the closest black hole to Earth in the HR 6819 system, just
1,000 light-years away
, only to have other scientists dispute the findings.
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 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.
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.
How fast is warp speed?
Warp one, a veritable snail’s pace in the world of Trek, is
equal to the speed of light
. Warp speeds exceeding warp one equal a multiple of C (the speed of light), but the exact speeds are variable, depending on the source material. It seems the Federation altered its scale as time went on.
How many dimensions are there?
The world as we know it has
three dimensions of space
—length, width and depth—and one dimension of time.
What is the closest wormhole to Earth?
Now, astronomers have discovered a black hole with just three times the mass of the sun, making it one of the smallest found to date—and it happens to be the closest known black hole, at just
1,500 light-years from Earth
.
Is an Einstein Rosen bridge possible?
Einstein and Rosen discovered that,
theoretically at least, a black hole’s surface might work as a bridge that connected to a second patch of space
. The journey might be as if you went down the drain of your bathtub, and instead of getting stuck in the pipes, you came out into another tub just like the first.
What is spice in Star Wars?
Spice was the name for
a type of illicit substance or substances in demand throughout the galaxy
. Spice was mined at the spice mines of Kessel, where slaves such as captured Wookiees were worked to death turning mined medicinal spice mineral into a recreational drug.
What is a Holdo maneuver?
Admiral Holdo, who stays behind on the rebel ship Raddus,
launches the vessel at lightspeed into an enemy Star Destroyer, cutting it in half in a gorgeous black and white silhouette
. It easily stands as one of the most beautiful shots in all of science fiction cinema, never mind just “Star Wars.”
Are jump points real?
A jump point is a point in space that marks the opening of a traversable wormhole (jump tunnel) that tunnels through interspace and opens to another location, often a different solar system.
In their natural state, jump points are nearly invisible to the naked eye
.
Has anyone been in a wormhole?
They, too, are a possible outcome of Einstein’s theory. However,
no one has ever observed a wormhole
, let alone passed through one.
What happens if you get stuck in a wormhole?
As long as a wormhole has a greater mass than any black hole it encounters, it should remain stable. If a wormhole encounters a larger black hole,
the black hole may disrupt the wormhole’s exotic matter enough to destabilize the wormhole, causing it to collapse and likely form a new black hole
, Gabella said.
Do you age slower if you travel at the speed of light?
That depends on how fast you’re traveling. Thanks to Einstein, we know that
the faster you go, the slower time passes
–so a very fast spaceship is a time machine to the future. Five years on a ship traveling at 99 percent the speed of light (2.5 years out and 2.5 years back) corresponds to roughly 36 years on Earth.
What is a white black hole?
White holes are
theoretical cosmic regions that function in the opposite way to black holes
. Just as nothing can escape a black hole, nothing can enter a white hole. White holes were long thought to be a figment of general relativity born from the same equations as their collapsed star brethren, black holes.
Does Earth have a black hole?
It’s a wild idea that isn’t necessarily based in nonsense, but the data we’ve collected has thoroughly demonstrated that
there isn’t a black hole at the center of the Earth
. Here’s the story of how we scientifically know that the Earth’s interior is black hole-free.
What if Earth goes into black hole?
Our atmosphere would start to be vacuumed up. And then huge chunks of the Earth would rip apart and follow suit
. If Earth managed to fall into the orbit of the black hole, we’d experience tidal heating. The strong uneven gravitational pull on the Earth would continuously deform the planet.
Does the past still exist?
In short, space-time would contain the entire history of reality, with each past, present or future event occupying a clearly determined place in it, from the very beginning and for ever.
The past would therefore still exist, just as the future already exists, but somewhere other than where we are now present.
Where does space end?
It extends
about 20 miles (32 kilometers) above the Earth
. Floating around the atmosphere is a mixture of molecules – tiny bits of air so small you take in billions of them every time you breathe.
Is time real or an illusion?
According to theoretical physicist Carlo Rovelli,
time is an illusion
: our naive perception of its flow doesn’t correspond to physical reality. Indeed, as Rovelli argues in The Order of Time, much more is illusory, including Isaac Newton’s picture of a universally ticking clock.
