What do you think of travelling faster than the speed of light??
I know it's impossible for "us" but, given our limited knowledge of Physics, is it safe to assume that it's simply impossible without considering things we still don't know??
There may loopholes you know.

some mass structures can travel faster than the speed of light.=See alternativephysics.org

Relativity and causality make a much stronger statement than "Nothing can travel faster than light". They say that nothing can get from one point in space to another faster than light can. If anything did so, a paradox of time travel would be created. Nature can never allow paradoxes.
This restriction prohibits wormholes, warp drive, hyperspace, entanglement, and any undiscovered loopholes from working. Going from A to B by any means in less time than light takes to get there will create a paradox, so it is impossible.

Ah yes, the old "humans can do anything" mantra.
We can't control the weather. Or earthquakes or volcanos.
In practice we cannot control our own population or food sources.
TV shows like to imagine living a normal life after death. In a different universe.
So I have no problem with the idea that it is quite impossible both theoretically and in practice.
Like King Canute trying to hold back the tide, we often get a false idea of our own capabilities and importance.
To the thumbs downer. You asked what I think. I think it is impossible. A fantasy. One entertained by feeble brains. Whether you agree with me or not isn't relevant to your question as asked.
If you believe something there should be some evidence. At this stage all the evidence is to the contrary.

darpa has perfected the warp engine . the 1 % knows AGW will make earth uninhabitable in less than 20 years . they are already terraforming mars . the 1 % gets a second chance , the rest of us get to slowly die from starvation .

I personally believe bending space time will be the solution to traveling Universal distances. If that is ever possible.

Relativity sets a limit on the maximum speed matter can travel assuming the matter starts out at a speed less than the speed of light. But, it does allow particles that start out at speeds above the speed of light to travel faster than the speed of light. These particles have been postulated - called tachyons- and there are numerous research papers on them. They plays roles in various models for a unified physics. Unfortunately, in order for the theory to work, tachyons have to have an imaginary mass (the energy of the tachyon has to be a real number forcing the mass to be a pure imaginary number). So this has various implications as to interactions and observability. What is accepted is that tachyons should generate Chernkov radiation which would be light speed electromagnetic waves. Thus, we should be able to detect tachyons by looking for their Chernkov radiation. No such particle have been detected to date in the various experiments that have looked for it.
But given our current understanding of the universe, the only way to take mass from sub-luminal speeds to super-luminal speeds would be through a worm hole - a path "around" space-time that doesn't limit the speed of travel. The first formulation of a worm hole was the Einstein Rosen bridge. Worm holes have not been observed and if they do indeed exist, it isn't clear if matter could survive in a passage through one as they are generally associated with black holes.

As of now, there are no known possible 'loopholes' in the laws of physics.
Sub atomic particles can go faster than light at the expense of the atom, but a biologic is simply never going to go faster than light.
General relativity would indicate becoming energy in such event.

assume long-blade scissors.
if the rings get closer by light speed, the tips will get closer higher than light speed.

To your point, if they ever discover negative matter, it could be the most credible way of sending signals faster than light. As of now though, nobody knows if it exist. As humans progress, if they don't destroy themselves, we may need to reevaluate the laws.

Apparently protons under quantum physics travel faster than light, and something is communicating far faster than the speed of light in entanglement so something beyond Einstein's law is going on.
