Speed is relative, so if you accelerated away from the sun at 0.999999c hoping to hang out in a slow-moving stream of solar neutrinos, you’d remove the energy needed for them to interact with the weak force. They’d be all around you, but you would have exponentially smaller chances of interacting with them.
