It would mean a change in physics as we know it.  Currently any physical body travelling at the speed of light would have zero length and infinite mass.  You would have to convert the physical body into an energy wave and reconstruct that energy wave back into a physical body as you slowed down.

It's just possible that some things we dream of are impossible.

Nope! Not in a warp bubble. It's space that's moving not the space ship. There's nothing preventing space itself from traveling faster than light. Imagine warp drive like the walkways at the airport, in that you are stationary but the walkway is moving. 

It might be that a warp bubble is still restricted to below light speed but not due to relativistic effects. Einstein doesn't mind space itself traveling at or beyond the speed of light. That's the entire point of the warp drive.

The "change in physics as we know it" relates to finding hypothetical negative energy and overcoming the other issues I mentioned early.

Edit: Sorry, just noticed others have already replied to this.

Chock, I m more interested in what we can do NOW. not 300 years from now.  Yes, there are warp theories and in time we may or may not developed devices to allow humans to travel at warp speeds and develop Star Trek like transporters and replicators.

A photon is a physical body that travels at the speed of light.  It's mass-less.  It's size is based on the wavelength.

A photon is a boson though, so not considered physical matter.  Noel was referring to a physical body, so has mass.

Nice video, this guy really explains things very well. Some quick clarifications:

- Things can move at the speed of light in vacuum, but only if they have zero mass. This includes electromagnetic radiation (photons) and gravitational waves (gravitons).

- The size of the photon can be very different from its wavelength, although the wavelength provides a natural length scale for it. Attosecond pulses are much shorter (about 1000s of a wavelength), but most photons are a million times longer than their wavelength.

- Photons are bosons indeed, but that does not distinguish them from physical matter. Many atoms and molecules are bosons, and so are some elementary particles (Higgs, Z and W bosons). It is mainly the vanishing rest mass that distinguishes photons from particles like electrons or protons.

Gravitons are hypothetical though.

Correct; but not gravitational waves.

I have been in two places at the same time... or at least people have claimed to see me in one place while I was at some other place.  Hmmmm... perhaps I have some special, almost X-men like power?

I've stood on a bridge between two cities with one foot on either side of the Border.... Does that count as being in two places at once? 🤔

Last night I watched 'Sergeant York' on TCM.  On one scene he was getting drunk in a saloon on the Kentucky - Tennessee border.  The border was painted on the floor of the saloon.  So by definition you can be in two cities or two states at the same time.

Being in two places at the same time sounds interesting, but not sure how my mind will handle it ... but I'm assuming by the time we develop this technology the human body will no longer be necessary.

Cheers, Rob.

 

People can't be. It's sub atomic particles that can be thought of that way.

I know you didn't say this Martin, but it was more convenient to copy Rob's phrase from your post than going back 15 hours.

If the human body will no longer be necessary that will take a great deal of fun out of life.  Sex for example.  We need our bodies for that.  Also fine dining.  A filet mignon or a slice of prime rib needs an appetite and taste buds and chewing to savor and enjoy.

No probs.

Depends what replaces the human body. We're certainly on the way toward cyborg technology, part man part machine, if so, we would still have emotions and the capability to experience pleasure.

Beyond that we can only speculate.  Science Fiction sometimes takes us into the realm of "energy beings" and all manner of weird stuff but we have no idea if such a thing is possible, weather by choice or as a consequence of evolution. However, if some kind of existence like that is possible, it doesn't mean we wouldn't have emotions and the propensity to experience pleasure.

Taste buds are just organic sensors, its the brain that generates the experience. No matter what we are, cyborg, AI, energy beings, such a thing would still be possible I would think.

Isn't everything we touch, feel, taste, hear, smell and see just our brain reacting to organic sensors?  Without those organic sensors what good is the brain except, perhaps, for pure thought?

Years ago there was a commercial for something or other that was just a head in a box.  Someone put the box on a table in a classroom for the head to deliver a lecture.  Then all the students left the room.  The head in the box was asking someone to move him someplace but nobody came.

If we are to evolve into just thinking creatures then I hope when I am reincarnated I become some kind of bird or animal, but certainly not human.
