I'm sure a lot of you have heard of the warp drive theory. I can't seem to find much on the bubble part, though. In theory, will the bubble be something you can actually see and touch?
Ryan_m_b said:At some point last year I looked into papers discussing the possibility of a warp drive, there's no indication that one could exist. Reason being that it would require exotic matter that probably doesn't exist (as it would violate energy conditions) and if it did would require astronomical amounts of energy. If you're interested this paper outlines the energy requirements and this paper which is further discussed in this paper proposes possible ways of getting around this . The "trick" is to change the warp bubble so that it's exterior radius is microscopic yet the interior radius is large enough to accommodate your vehicle (essentially making a warp bubble that's bigger on the inside than on the out). Apparently this would greatly shrink the amount of energy needed to manageable levels. Bear in mind though they don't outline how exactly a shell could be build around a ship in such a fashion nor how the ship could leave.
However neither of these approaches fixes the other problems of a warp bubble such as requiring the construction of an exotic matter shell, superluminal signalling to steer/control the bubble and the huge amount of radiation a warp drive subjects you to. There are some interesting (but technical) objections in this paper that apparently show that a warp drive would only be capable of very low velocities as well as highlighting other problems.
So without exotic matter that may not even exist we are stuck to trying to make slower than light vehicles. To make an interstellar vehicle would be fantastically complex though requiring horrific amounts of energy (even if we used an antimatter rocket we would need potentially thousands-millions of tonnes for a high fraction of c.) as well as a thorough understanding of ecology so as to make a stable environment in a closed system to keep the occupants alive.
I could be wrong but I'm pretty sure your question makes about as much sense as asking me what the colour of a unicorn's horn is, if one were to exist.Reptile202 said:In theory, if one existed, would it actually be a bubble visible to the naked eye?

Reptile202 said:All theoretical videos I've seen on them are showing an actual bubble in the diagrams. However, warping space-time doesn't seem like it'd make an actual visible bubble..that's capable of being seen. Which is why I asked. Too many videos use special effects.

Warp Drive is a theoretical concept in physics that proposes the possibility of faster-than-light travel by "warping" or distorting space-time. Bubble Theory, also known as Bubble Nucleation Theory, is a hypothesis that suggests our universe may have formed from a small bubble in a larger, pre-existing universe.
Warp Drive would work by creating a bubble of distorted space-time around a spacecraft, allowing it to travel faster than the speed of light. Bubble Theory suggests that our universe may have formed when a small bubble of space underwent a phase transition, expanding and cooling to form the universe we know today.
Warp Drive and Bubble Theory are currently only theoretical concepts and have not been proven or observed in real life. Therefore, we cannot see or touch them in their current form.
Warp Drive and Bubble Theory are still highly debated and remain unproven in the scientific community. While some theories and equations suggest they may be possible, we currently do not have the technology or understanding to make them a reality.
If Warp Drive and Bubble Theory were to be proven and successfully developed, it could revolutionize space travel and potentially allow us to explore distant parts of the universe in a fraction of the time it currently takes. It could also provide insight into the origins of our universe and the possibility of other universes beyond our own.
