The heat death of the universe appears to be more than just a theoretical supposition.
Already it has been documented that parts of the universe have reached the level of zero energy, that being absolute zero, zero degrees Kelvin, or -273 degrees Celsius.
This is the domain of the literally, frozen stars.
Observing these entities is quite difficult and requires special instrumentation because their state of zero energy – heat death – means they do not emit light energy or heat energy.
As a result, such domains have been purely hypothetical and impossible to confirm until now.
Now we have photoshop filters and these Ice Stars can be seen for the very first time.
No probes. No expensive funky, hi-fi telescopes.
