# The Warp Drive Problem: Can Negative Energy/Matter Exist?

• Mrwheatable
In summary, the conversation discusses the possibility of warp drive and the role of the Casimir effect in demonstrating negative energy/matter. The speakers question the accuracy of using the Casimir effect to calculate the energy required for a warp drive, given that there is currently no known method for obtaining negative mass/energy. The conversation also touches on the unresolved issue of unifying quantum theory and general relativity.

Time and Time again I see the same term being thrown around amongst people and countless Articles claiming that Warp Drive might be possible.

And that is through The Casimir effect.

Correct me if I am wrong but the Casimir effect does not demonstrate negative exotic matter. From my understanding the Casimir effect can only be interpreted as Negative energy. And it only proves that there is still a small amount of positive energy in "zeropointenergy" vacuum

If the Casimir Effect does not at all demonstrate the existence of Negative energy/matter than shouldn't it mean in principle alcubiers approximation of the energy required through the casmir effect is wrong?
Further more how exactly do you even attempt to calculate the energy required for a warp drive when there is absolutely no known method or creating or obtaining negative mass/energy.

Nasa and Harold are throwing around numbers such as The mass of Jupiter or the entire energy USA consumes in a year yet where are these numbers coming from?

Correct.

Within quantum theory, this is an arbitrary choice. Within general relativity, it is not, but the unification of those two is still an open problem.

You calculate the amount of negative energy you would need if you would have a source of it (and a way to get arbitrary distributions of it).

## 1. What is the warp drive problem?

The warp drive problem refers to the theoretical concept of using negative energy or matter to create a propulsion system that would allow for faster-than-light travel.

## 2. Can negative energy/matter exist?

While negative energy and matter have been theorized in the realm of quantum mechanics, there is currently no evidence to suggest that they exist in the physical world.

## 3. How would negative energy/matter be used in a warp drive?

The idea is that negative energy/matter would be used to create a bubble around a spacecraft, compressing the space in front and expanding the space behind, essentially creating a shortcut through space-time.

## 4. What are the obstacles to creating a warp drive?

Aside from the lack of evidence for negative energy/matter, the main obstacles for creating a warp drive include the immense amount of energy required, the need for advanced technology to manipulate space-time, and potential negative effects on the fabric of space-time itself.

## 5. Is a warp drive possible?

While it is currently a topic of scientific research and debate, the feasibility of a warp drive is still uncertain and would require significant advancements in technology and understanding of physics before it could be considered a possibility.
