Summary

TLDRThe video script discusses the possibility of interstellar travel through two theoretical methods: a propulsion system with a constant 1g acceleration or a warp drive. It highlights the impracticality of reaching distant stars like Proxima Centauri with current technology but suggests that the Alcubierre warp field theory, which involves space-time distortion using exotic matter, could potentially allow for faster-than-light travel. The script also mentions NASA's exploration of this concept and the challenges, including the unknowns of antimatter's interaction with gravity and the potential of the G bar experiment at CERN to shed light on this.

Takeaways

Q & A

  • What is the significance of the periodic table made by Engineered Labs mentioned in the script?

    -The periodic table by Engineered Labs is significant because it is made of acrylic and includes all known radioactive elements, even though it humorously mentions element 115, which is not a real element.

  • What are the two main propulsion systems discussed in the script for interstellar travel?

    -The two main propulsion systems discussed are a propulsion system that can burn for long periods at a minimum acceleration of 1g, and a warp drive that could potentially surpass the speed of light.

  • How does the script describe the potential speed of a ship with a 1g constant acceleration?

    -The script suggests that with a 1g constant acceleration, a ship could reach speeds in the millions of kilometers per hour.

  • What is the current travel time to Mars using conventional rockets, and how does the script compare it with the 1g acceleration scenario?

    -The current travel time to Mars using conventional rockets is between six to eight months, whereas with a 1g constant acceleration, it could be reached in just 2.5 hours.

  • How long would it take to reach Pluto with a 1g constant acceleration according to the script?

    -With a 1g constant acceleration, it would take just 73.7 days to reach Pluto, compared to the 9.5 years it took the New Horizons probe.

  • What is the distance to Proxima Centauri in light years, and what is the travel time without a warp drive?

    -Proxima Centauri is 4.2 light years away, and without a warp drive, it would take about 1,873 years to reach it with conventional propulsion methods.

  • What is the Alcubierre warp field theory, and what does it propose for space-time travel?

    -The Alcubierre warp field theory, proposed by Miguel Alcubierre, suggests that space-time can be distorted to allow for faster-than-light travel by creating a bubble around a ship that contracts space in front of it and expands it behind, moving the ship without it moving within the bubble.

  • What is the main challenge with the Alcubierre warp field theory in terms of energy requirements?

    -The main challenge is the requirement of a massive amount of energy, specifically exotic matter with negative mass, to create the necessary space-time distortion for the warp field to work.

  • What was Dr. Harold White's contribution to the Alcubierre warp field theory?

    -Dr. Harold White proposed a way to reduce the mass necessary for the warp field to work by oscillating between contraction and expansion states using a torus around the ship, which could potentially bring the theory closer to being realistic.

  • What is the G bar experiment at CERN, and what is its relevance to the warp field theory?

    -The G bar experiment at CERN aims to test the Einstein weak equivalence principle with antimatter, specifically neutral antihydrogen atoms, to see if they are repelled or attracted by gravity. This could provide insights into the behavior of exotic matter needed for the warp field theory.

  • What is the most plausible speed achievement using the warp field theory in the next 80 years according to the script?

    -The script suggests that achieving subliminal speeds of around 10% of the speed of light using the warp field theory is the most plausible scenario in the next 80 years.

🌌 The Alcubierre Warp Drive and Its Challenges

The second paragraph delves into the specifics of the Alcubierre warp drive theory, named after the physicist who proposed it. It explains the theoretical basis for the warp field, which involves creating a space-time bubble that contracts space in front of the ship and expands it behind, effectively moving the ship without it moving locally. The paragraph discusses the immense energy requirements for such a drive, particularly the need for exotic matter with negative mass. It also mentions Dr. Harold White's work at NASA to reduce the energy requirements by oscillating the warp field and introduces the concept of two tori to manage the thickness of the warp bubble. The summary concludes with the challenges of external factors like trapped energy and the potential for antimatter to play a role in future space travel technologies.

Keywords

💡Engineered Labs

Engineered Labs is mentioned as the sponsor of the video, known for creating unique acrylic periodic tables that include all known radioactive elements, even the fictional element 115. This keyword introduces the context of the video by highlighting the sponsor's innovative product related to the theme of science and exploration.

💡1g of constant acceleration

The concept of '1g of constant acceleration' refers to the idea of a propulsion system that could accelerate a spacecraft at the rate of Earth's gravity (9.8 m/sÂČ) continuously. In the video, it is used to illustrate the potential for reaching Mars in a significantly shorter time than current methods, emphasizing the importance of advanced propulsion for space travel.

💡Warp drive

A 'warp drive' is a theoretical propulsion system that allows for faster-than-light travel by bending space-time around a spacecraft. The video discusses the concept in the context of reaching distant stars like Proxima Centauri, highlighting the limitations of current propulsion technology and the need for such revolutionary ideas to make interstellar travel feasible.

💡Alcubierre metric

The 'Alcubierre metric' is a solution to the equations of general relativity proposed by physicist Miguel Alcubierre. It describes a method of traveling faster than light by creating a 'warp bubble' that contracts space in front of and expands space behind a spacecraft. The video explains how this metric is central to the concept of the warp drive and the theoretical possibility of faster-than-light travel.

💡Exotic matter

In the context of the video, 'exotic matter' refers to a hypothetical form of matter with negative mass that is necessary for the creation of a warp bubble, as it would have the unique property of warping space outwards, contrary to the inward warping caused by normal matter. The concept is crucial to the feasibility of the Alcubierre warp drive theory.

💡NASA

NASA, the National Aeronautics and Space Administration, is mentioned in the script as the organization that took an interest in the warp drive theory. Dr. Harold White from NASA's Eagle Works was involved in attempting to make the theoretical energy requirements for a warp field more realistic, showing the ongoing research and interest in advanced space travel technologies.

💡Thorus

A 'torus' in the video refers to a doughnut-shaped object that Dr. White proposed to use in oscillating between states of contraction and expansion to decrease the mass necessary for a warp field. The concept is integral to the idea of making the warp drive more plausible by reducing the amount of exotic matter required.

💡Antimatter

Antimatter is a type of matter composed of antiparticles, which have opposite charge and other particle properties compared to normal matter. The video discusses the potential of antimatter as a source of exotic matter for warp drives, especially if it is found to be repelled by gravity, which could revolutionize our understanding of physics and propulsion.

💡G bar experiment

The 'G bar experiment' at CERN is aimed at testing the weak equivalence principle with antimatter, specifically by measuring the free-fall acceleration of neutral antihydrogen atoms. The video mentions this experiment as a means to potentially uncover new insights into the behavior of antimatter in a gravitational field, which could have implications for the development of warp drive technology.

💡Proxima Centauri

Proxima Centauri is the closest known star to our solar system, approximately 4.2 light years away. The video uses it as an example of a destination for potential interstellar travel, discussing the time it would take to reach it with current technology versus the theoretical capabilities of a warp drive.

💡Einstein weak equivalence principle

The 'Einstein weak equivalence principle' is a fundamental principle of general relativity stating that the trajectory of a test particle in a gravitational field is independent of its composition and internal structure. The video explains that the G bar experiment aims to test this principle with antimatter, which could provide crucial insights into the behavior of antimatter in a gravitational context.

Highlights

Engineered Labs creates cool acrylic periodic tables, including element 115.

To reach the nearest stars, we need a propulsion system with 1g acceleration or a warp drive.

At 1g constant acceleration, Mars could be reached in 2.5 hours, compared to current 6-8 months.

The same acceleration could get us to Pluto in 73.7 days, instead of the 9.5 years New Horizons probe took.

Proxima Centauri, 4.2 light years away, would take 1,873 years to reach without advanced technology.

A warp drive could theoretically get us to Proxima Centauri in 153 days at 10 times the speed of light.

Miguel Alcubierre's warp field theory suggests faster-than-light travel is possible within general relativity.

The warp bubble concept involves space-time contraction in front of the ship and expansion behind it.

Exotic matter with negative mass is required for the warp field to work, as it warps space outwards.

NASA's Dr. Harold White aimed to reduce the energy needed for a warp field using oscillating tori.

With two oscillating tori, the warp bubble's thickness can be controlled, allowing for safe travel.

Stopping the warp drive could release a high-intensity energy burst forward, which is a significant challenge.

Antimatter's interaction with gravity is a mystery and could potentially be used as exotic matter.

CERN's G bar experiment aims to test the weak equivalence principle with antimatter.

If antimatter is found to be repelled by gravity, it could revolutionize our understanding and possibly be used for propulsion.

Achieving subliminal speeds with warp fields, like 10% of the speed of light, is considered the most plausible near-term goal.

hello guys just a quick shout out to

play00:02

engineered labs today's sponsor they

play00:04

make these really cool acrylic periodic

play00:07

tables and they even have element 115

play00:09

well not really but they have all known

play00:12

radioactive ones check them out link in

play00:14

the description trouble is to the

play00:21

nearest stars in this century as

play00:22

possible but only if we managed to

play00:24

achieve one of two things a proportion

play00:27

system that is able to burn for long

play00:29

periods of time at a minimum

play00:31

acceleration of 1g or some sort of warp

play00:34

drive just to put this into perspective

play00:36

if we had a ship like in the expence

play00:40

universe we could reach speeds in the

play00:42

millions of kilometers per hour think

play00:45

about this at a 1g of constant

play00:47

acceleration and burning for about

play00:49

nineteen point two hours we could reach

play00:52

Mars at its closest distance to earth or

play00:54

55 million eight hundred thousand

play00:57

kilometers in just thirty 2.5 hours

play01:00

compared to the current time which is in

play01:03

between six to eight months that's a

play01:05

huge gain just to show you how much this

play01:09

really matters the same acceleration

play01:11

would grant us a trip to Pluto in just

play01:14

seventy three point seven days it took

play01:17

the new Horizons probe nine point five

play01:19

years to get there so Rockets will help

play01:22

us a lot with the exploration of our own

play01:25

solar system and it is a topic that I

play01:27

will be exploring in later videos but

play01:30

what about other stars like Proxima

play01:31

Centauri which is 4.2 light years away

play01:35

well to reach Proxima Centauri at 40

play01:38

point 14 trillion kilometers away it

play01:40

would take about six hundred eighty

play01:43

three thousand four hundred sixty five

play01:44

days or 1,873 years to be exact but then

play01:50

again taking to account all other

play01:52

problems related to traveling this far

play01:54

let's face it it's just not viable the

play01:58

Alcubierre warp field would help us

play02:00

surpass the speed of light many times

play02:03

which means that if we had a ship that

play02:05

could go 10 times the speed of light

play02:07

it would take only 153 days to get to

play02:10

Proxima Centauri much more reasonable of

play02:13

it

play02:13

but building a warp drive is not an easy

play02:16

task hello everyone

play02:22

subject zero here Miguel Alcubierre is a

play02:26

theoretical physicist famous for the

play02:28

warp field theory in May 1994 he

play02:31

published a paper titled the warp drive

play02:33

hyper fast travel within general

play02:36

relativity however his goal of this

play02:38

paper contrary to popular belief had

play02:41

little to do with warp drives it was to

play02:43

show that a distortion of space-time is

play02:46

indeed possible within the realms of

play02:48

general relativity and therefore we

play02:51

could travel faster than the speed of

play02:52

light his objective was simple he wanted

play02:55

to verify if there was a way to deform

play02:57

space in such a manner that its

play02:59

contraction and expansion would provide

play03:02

movement to a body inside the space-time

play03:04

warp bubble the idea was to form a

play03:07

bubble around the ship and at the same

play03:09

time the inside of the bubble would

play03:11

remain untouched or flat as they say we

play03:15

all know that huge masses can warp space

play03:17

so the idea came from two factors the

play03:20

ability for space to contract like what

play03:23

happens with large concentrations of

play03:25

matter and expand which is what is

play03:28

happening with the universe the only

play03:29

problem with his idea is that the

play03:31

transition from contraction to expansion

play03:33

requires a massive amount of energy

play03:36

mainly focus on what they call exotic

play03:39

matter with negative mass as complex as

play03:42

it may appear to be in this case since

play03:44

normal matter warp space inwards is why

play03:47

we have gravity negative mass would warp

play03:50

space outwards this is the key of his

play03:54

warp field theory to better visualize

play03:56

this think of it as the path of the ship

play03:58

inside a tube in order for the warp

play04:01

field to work it would contract the

play04:03

front of the tube towards the ship

play04:04

bringing some distant point of

play04:06

space-time closer to it and as it

play04:09

approaches the center it slowly

play04:10

transitions to an expansion behind it so

play04:14

space-time moves around the ship and

play04:16

inside the bubble nothing is moving or

play04:18

space-time remains flat since there is

play04:22

no known limit to how space-time can

play04:24

contract or expand in theory anything

play04:27

inside the bubble can travel faster than

play04:29

the speed of light all you need to do is

play04:31

increase the warp field

play04:36

about ten years later NASA picked up on

play04:39

this project and dr. Harold white from

play04:41

Eagle Works stepped in to verify if the

play04:44

amount of energy necessary for the work

play04:46

field to work could be brought down to

play04:48

something more realistic his great

play04:50

insight was to oscillate in between

play04:52

states or from contraction to expansion

play04:55

by using a thoris around the ship he

play04:58

derived his calculation from the

play05:00

Alcubierre metric and described three

play05:02

main functions the warp bubble shaping

play05:04

function york time which is the measure

play05:07

of expansion and contraction of space

play05:10

and energy density this is when we get

play05:13

this chart what he proposed was that to

play05:17

decrease the mass necessary to make this

play05:19

work and have your ship traveling at 10

play05:22

times the speed of light you could in

play05:24

turn increase the oscillation of the

play05:26

torus using the york time function but

play05:29

that comes at a cost with a mass

play05:31

equivalence of Jupiter you would have

play05:33

the optimal work bubble conformation

play05:35

that would enable a ship to be located

play05:38

inside the bubble without any distortion

play05:40

or any harm to the ship as you increase

play05:43

the oscillation you diminish the total

play05:45

exotic mass requirements up to a point

play05:47

where all you need is about 700

play05:49

kilograms of exotic matter but the

play05:52

bubble would be so thick pretty much

play05:54

destroying anything inside the bubble

play05:56

that is when the second torus is

play05:59

introduced with two oscillating Tauri

play06:01

the thickness of the warp bubble can be

play06:04

controlled allowing for flat space to

play06:06

exist inside the bubble keeping

play06:08

everything intact even if we managed to

play06:11

make that ship we still have to deal

play06:13

with other external factors like for

play06:15

instance all the trap energy in front of

play06:18

the bubble anything that is on the way

play06:20

of the ship route would get stuck in

play06:23

front of the bubble so when you stop the

play06:25

ship the energy would be released

play06:27

forward with high intensity so one thing

play06:30

to avoid at all time would be to point

play06:32

your ship at the planet or whenever you

play06:34

arrive you'll pretty much destroy the

play06:36

planet

play06:38

then again this is getting more and more

play06:40

complex by the minute and in the same

play06:42

fashion as a queer all dr. white

play06:44

attempted to do here was to bring the

play06:46

war field theory to of the realm of

play06:48

maybe plausible and that is exactly what

play06:51

he achieved one thing almost all

play06:53

scientists discussing this topic agree

play06:55

is that warping space is possible or at

play06:58

least the numbers tells us that is

play07:00

possible nevertheless what is most

play07:03

likely to happen is work field achieving

play07:06

subliminal speeds like 10% of the speed

play07:09

of light that is by far the most

play07:11

plausible scenario for the next 80 years

play07:13

and 10% of the speed of light is a big

play07:16

deal

play07:17

after all to achieve the same speed

play07:19

using rocket technology you would have

play07:21

to burn at 1g of constant acceleration

play07:23

for 35 days think about that what could

play07:28

change everything though is antimatter

play07:34

there is something about antimatter that

play07:36

we don't know and most likely it will

play07:39

take years for us to acquire a

play07:41

definitive answer for it that is how

play07:44

does it react with gravity is it

play07:46

repelled or is it attracted by it like

play07:49

anything else or better yet what kind of

play07:52

gravitational field would large

play07:54

quantities produce the thing is we

play07:57

really don't know but tests at the CERN

play08:00

facility with G bar experiments will

play08:02

give us some clues this decade how

play08:04

antimatter behaves with gravity is still

play08:07

a mystery and so far no experimental

play08:10

direct measure has ever been

play08:12

successfully performed the goal of G bar

play08:15

is to test the Einstein weak equivalence

play08:18

principle which states that the

play08:20

trajectory of a test particle is

play08:22

independent of its composition and

play08:24

internal structure when it is only

play08:26

submitted to gravitational forces this

play08:28

fundamental principle has never been

play08:31

directly tested with antimatter G bar

play08:34

will directly measure the freefall

play08:36

acceleration note a G of neutral anti

play08:40

hydrogen atoms in the terrestrial

play08:42

gravitational field then again it will

play08:44

take years for us to gather enough

play08:46

quantities anyway whatever they will be

play08:48

able to produce this year although

play08:50

helpful will most likely be inconclusive

play08:52

in many aspects but remember what we are

play08:55

looking for is a concentration of mass

play08:58

that will allow us to expend space but

play09:00

if the experiment is successful and

play09:02

antimatter turns out to be repelled by

play09:04

gravity aside from revolutionising

play09:06

everything it could in theory be used as

play09:10

the exotic matter that al Kabeer

play09:11

described or at least open the door to a

play09:14

completely new field of physics alright

play09:17

folks that's it we're done here

play09:23
