If we can get particles at CERN to near-light speeds, why can’t we extrapolate that to rockets?

Question

Alternatively, why can’t we put a particle accelerator on the back of a rocket and use that?

Edit: okay thanks guys it was a dumb question I see that now lol

Answer 1

A single electron weighs 0.0000000000000000000000000000009 kg

So the energy required to accelerate it to near light speed is relatively low.

The lunar landing module was around 5000kg, so you’re talking 35 orders of magnitude more energy than CERN.

That’s before you even get to issues of material strength and acceleration. An electron can survive 100,000g of acceleration, an astronaut would be pulped into orange juice.
