The Uncertainty Principle is vague on this: if the transition happens in Planck time, nothing. If it takes longer, you get a black hole which completely violates the Chandrasekhar limit.

This is truer than you might think. The metric tensor doesn't allow for the spontaneous adding or removal of mass and energy.

A temporal displacement caused by a quantum singularity most commonly affects delta-series radio-isotopes.

Really though, wouldn't the idea of traveling by bending space-time make more sense than simply traveling faster than light if somehow both could be done? Just saying, the point of this is to be able to travel somewhere as quickly as possible, no?

Yeah, there's a lot of shit like time dilation and inertia that you don't have to deal with if you warp space. Why I never really got the inertial dampers on Star Trek. What inertia? You're standing still within a moving bubble.

The dampers are micro-vector dependent: they don't effect any intra-ship movement out of line with the dominant macro-vector / warp metric, ie, overall ship direction.

Impulse engines and thrusters are the point of the inertial dampeners.

Going from 0 to .75c in 5 seconds would turn meatbags into meat mush.

Unless you're dealing with negative matter. Then negative momentum becomes a literal thing.

If we found a way to reduce an objects mass, or remove it completely. ( This may be impossible, I know)
1.Can said object accelerate to light speed or beyond?

From what we know about massless particles, such a thing will always move at the speed of light.

2. Would said object accelerate or instantly be light speed as soon as its mass reaches 0?

Instantly, I guess.

3. If it needs to accelerate, how much power do you need to move an object with no mass?

None I suppose.

4. What if we discover in the future that sunlight actually does have mass?

Sunlight has energy. Which is more or less the same thing as mass.

And from all the (un)happy talk I've heard about the Alcubierre drive from online physics circles, negative matter(planetary sized quantities of it at that) is apparently gonna play a game-changing role in the upcoming FTL renaissance.

I mean what if we discover the photons actually do have mass like any other object does?
if it actually has weight

Then with all the photons that bombard us all the time, we're gonna be wondering how we're still intact. We're also going to be wondering how a particle with mass is being created and annihilated. It's also going to undo every model and equation.

If some one does discover that its true, I doubt scientist would accept it ,because of vast amount of science which it would undo.

how would you reply to my last comment

First and foremost, as mass is defined now, it's impossible for photons to have mass.

Secondly, fundamental physics is one of the most elitist fields in all of science. None of the doctors, docents, or professors I've worked with from the department of fundamental physics would ever tolerate such an oversight.

Yes.

Post your course schedule for me again, it gets me all hot.

Then turning on a light would kick back.

This post probably made Bardock42's blood boil.

But, no, you're not.

Do you?
