👉 In physics, "ultragrave" is a term used to describe objects that have such high relativistic speeds and energies that they are considered to be beyond the reach of current technological capabilities. These objects can exist in space without any known means for escape or re-entry, which makes them potentially hazardous or even dangerous. The concept of ultragrave has been proposed by many physicists and astrophysicists over the years, but it remains a topic of ongoing research and speculation due to its
