I tried reading Einstein's original paper on special relativity. Night after night for 6 months I tried to understand it. I tried everything. I looked through previous publications to understand the knowledge at the time. I tried to work through some problems and I thought about the theories in novel ways to try to get an intuitive grasp or even any at all. It probably didn't help much that I didn't have the appropriate background in math. I tried learning the math, I even tried talking to experts. Still, nothing made sense. It just wouldn't click in my head. I toiled over this complex theory, wasting many notebooks of scrap paper trying to make sense of it. Many long nights later, I came to an amazing epiphany; I can't read German.

That was a good one. I have already allotted myself ten years to get through Einstein's Field Equations. The only thing I need to do now is get started.

[@hans-joachimbierwirth4727]

Try to get it this way: Einstein's equations describe the relations between different masses in a way that give each pair of masses in the universe an individual relation that can be perceived as space multiplied by time. In other words: there is no space beyond that relation. Independent space does not exist.

It is not an uncommon thing for passengers to notice, when in, and for a considerable distance beyond the centre of the Channel, the Light on Holyhead Pier, and the Poolbeg Light in Dublin Bay. The Lighthouse on Holyhead Pier shows a red light at an elevation of 44 feet above high water; and the Poolbeg Lighthouse exhibits two bright lights at an altitude of 68 feet; so that a vessel in the middle of the Channel would be 30 miles from each light; and allowing the observer to be on deck, and 24 feet above the water, the horizon on a globe would be 6 miles away. Deducting 6 miles from 30, the distance from the horizon to Holyhead, on the one hand, and to Dublin Bay on the other, would be 24 miles. The square of 24, multiplied by 8 inches, shows a declination of 384 feet. The altitude of the lights in Poolbeg Lighthouse is 68 feet; and of the red light on Holyhead Pier, 44 feet. Hence, if the earth were a globe, the former would always be 316 feet and the latter 340 feet below the horizon!” -- Dr. Samuel Rowbotham,* ~ *_Earth Not a Globe!_* *“The lights which are exhibited in lighthouses are seen by navigators at distances at which, according to the scale of the supposed ‘curvature’ given by astronomers, they ought to be many hundreds of feet, in some cases, down below the line of sight! For instance: the light at Cape Hatteras is seen at such a distance (40 miles) that, according to theory, it ought to be nine-hundred feet higher above the level of the sea than it absolutely is, in order to be visible! This is a conclusive proof that there is no ‘curvature,’ on the surface of the sea - ‘the level of the sea,’- ridiculous though it is to be under the necessity of proving it at all: but it is, nevertheless, a conclusive proof that the Earth is not a globe.” -- William Carpenter,* *_100 Proofs the Earth is Not a Globe_* Surveyors, engineers and architects are never required to factor the supposed curvature of the Earth into their projects. Canals and railways, for example, are always cut and laid horizontally, often over hundreds of miles, without any allowance for curvature. (self.conspiracy) The London and Northwestern Railway forms a straight line 180 miles long between London and Liverpool. The railroad's highest point, midway at Birmingham station, is only 240 feet above sea-level. If the world were actually a globe, however, curving 8 inches per mile squared, the 180 mile stretch of rail would form an arc with the center point at Birmingham raising a full 5,400 feet above London and Liverpool. Adding the station's actual height (240 feet) to its theoretical inclination (5,400 feet) gives 5,640 feet as the rail's necessary height on a globe Earth, more than a thousand feet taller than Ben Nevis, the tallest mountain in Great Britain. *The Suez Canal which connects the Mediterranean Sea with the Gulf of Suez on the Red Sea is a clear proof of the Earth's and water's non-convexity. The canal is 100 miles long and without any locks so the water within is an uninterrupted continuation of the Mediterranean Sea to the Red Sea. When it was constructed, the Earth's supposed curvature was not taken into account, it was dug along a horizontal datum line 26 feet below sea-level, passing through several lakes from one sea to the other, with the datum line and the water's surface running perfectly parallel over the 100 miles. The average level of the Mediterranean is 6 inches above the Red Sea, while the flood tides in the Red Sea rise 4 feet above the highest and drop 3 feet below the lowest in the Mediterranean, making the half-tide level of the Red Sea, the surface of the Mediterranean Sea, and the 100 miles of water in the canal, all a clear continuation of the same horizontal line! Were they instead the supposed curved line of globe-Earthers, the water in the center of the canal would be 1,666 feet (502 x 8 inches = 1,666 feet 8 inches) above the respective Seas on either side!*

No. Alcubierre found a window to make things feasible whithin known laws of physics. Now, it certainly had other problems to be solved, like the amout of energy needed, or the means to create the deformations of space-time, but it set the first stone for everybody else to make adjustments. If the math now makes better sense, it because it is based on the original idea. So no, it was exactly the opposite.

@Bliss Okpu If petitionary prayer worked, things would be different. For example, hospitals that organized prayer for patients would have better results than hospitals that don't. They would advertise this service and we would have statistics about how well it works. Many people have difficulty confronting these issues because they have been taught that they will go to Hell if they get the answer that their church doesn't like. If you are in that category, I don't blame you. Cult exit phobias are not going to be repaired by KZbin posts.

[@tim57243]

@Bliss Okpu You asked God to make this video age well. That isn't adding to the direct word of God? Whatever. Getting your beliefs to make sense isn't my problem. In any case, either prayer moves things in the direction you ask for on the average, or it doesn't. Presenting a wall of text can't change that. I agree with you that millions of people claim to have been helped by God. The claim that prayer helps is a statistical claim so it wants statistical evidence. The people who believe it don't think very well about statistics. I also agree with you that people who have been Christian for a long time are able to make their thoughts conform without much explicit thought about Hell. For example, my statement about hospitals didn't get much response from you. It is called thought stopping, and like other skills people get better at it with practice. If you want to see thought stopping in action, try to read and understand the following two sentences: There are known techniques that could have caused reliable transmission of the Gospels without starting with four discordant versions and then having everyone do their own edits for hundreds of years. A loving and omniscient God would have used them. (Edit: You probably have lots of friends who share your beliefs, and you may not be able to afford being in conflict with them. I can't provide you with new friends via a KZbin comment, nor can I change their beliefs en masse with a KZbin comment that you will see and they won't. So it probably makes perfect sense for you to ignore me or deflect what I say. I'm speaking mostly for the benefit of other people who come by this thread. I expect you to be a lost cause for the next few years at least.)

[@polychoron]

I read this too many years ago, & am not sure how to find it again. But I have read about studies that do show prayer has statistically significant benefits.

@@EoWKen Wrong. the vast majority of physics is what we have gleaned from empirically evidenced results of experiment. To say that the theoretical stuff that tries to extend that with rigorous mathematical models is anywhere close to having faith and making up complete nonsense like with religion, is to completely misunderstand what we know and how theoretical physics is done. Indeed, Sabine rails against those theories that seem not to be supported but are popular, like those that rely on an idea of "symmetry" just for the sake of it.

Even subluminal warp travel would have loads of advantages, to include moving debris out of the way I believe. Even if we can't go faster than light, we're gonna at least get close to C and things hurt when they hit ya that fast.

[@raminagrobis6112]

The fastest man has ever travelled in space so far is 0.00004*c, a record established during the Apollo program. A nearly 50-yr old record!. We thus have a long way to go. For many technical reasons, it has been predicted that the fastest speed achievable using the same overall vehicle design and with the best theoretically & practically useful propulsion energy source (e.g. controlled fusion), with the exclusion of fantasy solutions such as matter/antimatter, would be about 0.4*c in the BEST scenario, but more conservatively, more probably smtg in the vicinity of 0.2*c, which would already be a massive advance (a 5000-fold increase in speed is nothing to be ashamed of). Over that value, relativistic problems start getting "seriously" in the way and the energy required to increase momentum becomes exponentially more critical. Warp speed engine-based design would improve that limit for sure. And we haven't yet considered the impact of hitting debris, small meteorites, etc., which will certainly become a major factor in establishing a safe limit to the maximal velocity any vehicle will reach in practice.

[@guss77]

The fastest man made object is the Parker Solar Probe (by Applied Physics Laboratory - probably not the same Applied Physics from the new paper) that, using a Sol gravity assist, has reached speeds around 0.0006c which is close to 3 times the speed of the previous record holder - the Helios B solar probe (apparently, the sun is pretty good at accelerating things - who would've thought 😜)

Thus, the simplicity. Again, just because something is simple to explain doesn't mean that it is easy to understand, only that the logical steps and the assumptions behind them, especially new assumptions, required to reach the answer are, relatively, few.

It would actually make sense for them to move differently on planetary surfaces, since air resistance would be the most important factor, and you generally wouldn't want to travel anywhere near the speed of light in the vicinity of a planet. Not only would you get vaporized by the friction, but if you happened to hit anything in your path, well you would also be vaporized.

[@Xeno_Bardock]

Saucers don't move, they fall at desired direction. Because saucers are always stationary inside the bubble of spacetime, more accurately the vortex ring of ether. The shape of saucer is likely because it is an important shape to create a controlled vortex ring of ether/spacetime curvature around the saucer with powerful electromagnetic force and not necessarily due to friction reason.

[@Xeno_Bardock]

A saucer in space is not in a danger of being destroyed as long as its vortex ring of ether/spacetime curvature field/bubble is up and running. Everything whether it be an asteroid, rarefied gas or even light, it will go around the saucer instead of colliding head on, same with friction problem. It is better not to compare a saucer flying from point A to point B with an airplane flying. They are not flying in conventional fashion.

[@Dragrath1]

@@Xeno_Bardock I would imagine that in such warped spacetime as the boundary region there would probably still be exotic effects on any such material is it is deflected as the high curvature is in GR terms going to result in an apparent acceleration of course that material is generally so rarified that it wouldn't be readily observable but I would expect it to still have some form of feedback on the warp drive likely relating to loss of energy/stability of the warp field so it likely still would be a bad idea to do warp driving near matter or other concentrations of energy

If it does then even if one can't get the bubble to travel at superluminal speeds, it might be that it makes fast travel between stars safer, as it would avoid the collision with small particles at relativistic speeds.

I would love if you would revisit this subject in light of the new 2021 paper of Erik W Lentz. You made me understand how an Alcubierre drive would really work and now I would like to hear your thoughts on this paper that aparantely makes the Warp drive possible with normal, positive energy. Albeit a whole lot of it. At least for now.

[@jdranetz]

I guess we need "The Spice Melange" or dilithium crystals.

[@cpasr8065]

Dilithium won't help here as i) it regulate positive energy production and ii) doesn't create warp fields that and iii) ST ftl travel is way more different than what is theorised. But you are right about needing something as exotic like those.

[@Calaverna]

melange only allows to foresee safe superluminar pathways - the Holzmann drive is what pushes ships in the Imperium

[@FractalNinja]

Antimatter! :D

[@steamycarafe]

Or a "flux capacitor"

[@swifty1969]

Forget dilithium crystals, they’re prone to get unstable and ignite from Kelpian scream.....;)

Can u warp space without warping time? Wouldn't you risk getting there before u left?

[@magnuson2018]

Woa.

[@tylarrose]

That's one of the reasons you can't travel faster than the speed of light, if it were possible, you could get back before you left

"There was a young woman named Bright, whose speed was much faster than light. She departed one day, in a relative way, and returned on the previous night."

8:56 "You keep them moving normally in the bubble, but then you move the bubble itself superluminally." That reminded me of that gem of a SF movie _Explorers_ (1985) where a group of teenage boys find out how to create a bubble that can move at great speed while anything or anyone inside the bubble is unaffected.

Thanks for this video. There is one thing I don’t understand - why do people think that what the space time in your warp bubble is doing will be affected by the space-time outside of it? For example, is there any evidence that distant galaxies in their space-time are affected by the space-time in our galaxy? I would think that a ship in a warp bubble would be unaffected by the space-time outside, and therefore not experience any acceleration or movement effects within the local space-time. Therefore the bubble could move at any multiples of c with no effect on objects inside. They would experience no acceleration or inertial effects at all. Thanks, Greg.

Finally a good explanation why UFO's are saucer shaped.

[@KraussEMUS1]

Hi Sabine, I still don't know if warp drive will be possible in the near future. It doesn't seem so, though it's absolutely worth studying. There is however an ion drive, on my channel, that lifts its power supply against Earth's gravity. It might also be able to utilize relativistic electrons as propellant someday as well. Even though that upgrade is still theoretical, there is some mathematical support for it.

0:11 Not to be pedantic but Warp Drive is from the Star Trek Universe and the model that you flashed on the screen when talking about Warp Drive is an X Wing from the Star Wars universe. The faster then light travel in that universe is called hyperdrive. With that being said and my nerdy needs satiated, great video. Very informative.
