Question Re: Another theory on FTL travel

I believe you. I am not going to go item by as there is much to respond to, just
highlights.

Through this theory time also appears to dialate for the individuals within the ship the closer the ship gets to light speed - in an ideal scenario this would want to be avoided so that the astronauts onboard could maintain an even frame of reference for travel time, actual date and times based on Earth (most likely GMT) for the purposes of mission logs, it may also aid in navigation and course plotting.

To overcome the time differential we could look to the use of a Alcubierre metric to generate the necessary spatial wave form to "carry" the ship from point A to point B. ...

In a previous thread WebFeet suggested the use of an Aether bubble. ...

..

What I haven't been able to theorize is what would generate the Aether bubble and how the ripples could be generated.
A series of incorrect/misleading/incomprensible statements:

1. [Paraphrased]FTL ... an object cannot have mass
Incorrect: Any such object/particle were it to exist would have imaginary mass. This
does not make sense in a real world. Admittedly I haven't studied Roger Penroses
Twister Theory as yet (want to). From what I do understand dimensions (spatial ones)
are extended into complex numbers which can allow for imaginary values. Still what
does that mean.

2. You're a century of. Einstein got rid of the need for "Aether" in SR.

3. "...It occurs to me that the closer to light speed the ship gets it would probably be expending increasingly less fuel and generating increasingly lessened thrust as well."
DUH?: Add this one to growing list of silly quotes. "If we go faster we need less" ???

4. "...time also appears to dialate for the individuals within the ship."
In who's reference. Not theirs! If someone were magically able to watch their faces
the whole time in their travels. They would notice the dialation of time. How would
you go about avoid such?

5. Call me ignorant. What is an "Alcubierre metric" ?

6. How do you go about creating an "Aether bubble when Aeter doesn't
exist ? I guess you answered this question in that you don't know (yet?) !

Excuse me for asking, do you like live near an indian reservation. Just wondering because
I have heard that there Peyote is mighty rightous and I thought maybe you had taken a
few buttons when you came up with this.

I have to go now. However, after I give it some thought I will come and post here the
notion about Tachyons (said to be a class of theoretical particles that are FTL in nature).
I am not saying such particles exist or not. Conventional wisdom and the current Standard
Model says they don't. Let me state in a new post.

Please help me out and if you have details on my question 5 and 6 (those are the only ones
I want to know more about). Call me adventerous.

Hypography?

Hypography [n.]: A combination of "hyperlink" and "bibliography" - ie, a list of links to electronic documents. Comparable to discography and bibliography, but not cartography.

We have been online since May 2000, and aim to be the best place to find and share science-related content of all kinds.

Share the love!
