Max Speed of Molecules: 1 Electron Stripped?

Click For Summary
SUMMARY

The discussion centers on the maximum speed achievable by complex molecules, particularly those with at least two nuclei and most electrons intact. It is established that while charged particles can be accelerated to speeds close to the speed of light (c), the structural integrity of molecules limits the acceleration that can be applied without breaking them apart. The monotomic hydrogen in the Large Hadron Collider (LHC) serves as an example, demonstrating that molecules can indeed reach relativistic speeds without disintegration, provided the acceleration remains sufficiently low.

TL;DR
What is the maximum speed we accelerated molecules without striping more than one electron?
I know that we accelerated charged particles very close to the speed of light. How about a full molecule, with at least 2 nuclei and most of the electrons? What is the maximum speed achieved/recorded before the molecule broke apart?

I ask this question because I'm afraid that the maximum speed of travel for complex structures (like us, our robots, etc.) may be much lower than c. If it is much lower, then interstellar travel may be even less possible/appealing.

Speed itself has no effect on a bound system. It can't by the principle of relativity.

It's possible that a large enough acceleration could cause a molecule to break apart, but that doesn't limit the speed you can reach, it just limits the acceleration you can use to reach it.

Other side of the coin: since speed is relative, we/earth are already traveling at high relativistic speed in/with respect to some frames/objects.

There is no experimental or theoretical basis for this fear.

It's not clear why this is in Relativity, but the monotomic hydrogen in the LHC has only one electron stripped and is going pretty darn fast.

If this doesn't "count", as I suspect it doesn't, we can add this thread to the list of the OP's "guess what I mean" threads.

So, if the acceleration is low enough we can reach any speed, below c, without braking apart?

I was about to ask for some estimation of this maximum acceleration and to insist about a maximum speed obtained in a particle accelerator for a molecule with only one electron missing (in order to become charged), but I realized that, at high speeds, centripetal acceleration gets very big, so it's impossible to achieve really high speeds (close to c) for molecules, here on Earth, without very large accelerations.

In this case, there is no point to continue here. Thank you for your answer!

What you offered seems to be a proton, and I said:

As measured relative to an ion doing 0.9999c in an accelerator, you are doing 0.9999c. Unless you reject the principle of relativity you already have ample evidence that molecules can reach very nearly the speed of light.

Yes.
