'Emergent gravity' could force us to rewrite the laws of physicsThe idea of emergent gravity is still new and requires a lot of assumptions in its calculations to make it work. But if experimental evidence ever proves it real, we would need to totally rewrite the laws of physics.

There may be a 'dark mirror' universe within ours where atoms failed to form, new study suggestsThe invisible substance called dark matter remains one of the biggest mysteries in cosmology. Perhaps, a new study suggests, this strange substance arises from a 'dark mirror universe' that's been linked to ours since the dawn of time.

Einstein's predictions mean rare 'gravitational lasers' could exist throughout the universe, new paper claimsA new study combining two of Albert Einstein's famous predictions suggests that ripples in space-time can combine into 'gravitational lasers', firing out of black holes in random directions across the cosmos.

Scientists may finally know where the biggest, oldest black holes in the universe came fromThe presence of supermassive black holes in the earliest epochs of the universe has scientists stumped — but repeated explosions from tiny black holes may offer an explanation.
-
Cosmic strings can break — and when they do, they shake the universeMany models of the universe predict the existence of countless invisible strings stretching across space. New research finds a way these strings might snap — and how we could feel the fallout.

Turbulent 1st moments of a black hole's life captured in new simulationsScientists modeled how black holes and neutron stars form after dying stars collapse, and explained why some get a hard 'kick' into interstellar space.

Millions of invisible 'mirror stars' could exist in the Milky Way, and astronomers know how to find themAn entire universe made of 'dark' particles could exist within our own, and astronomers may know the first place to look: In the mysterious hearts of supposed 'mirror stars'.

The 1st life in the universe could have formed seconds after the Big BangThe first life-forms capable of evolution could have appeared just moments after the Big Bang, a physicist explains.

Building blocks of life may have formed on dust in the cold vacuum of spaceFar from any galaxy, icy grains of dust in deep space may be able to form organic molecules, a new preprint study finds.
-
Dark matter may have its own 'invisible' periodic table of elementsDark matter may come in multiple particles and weights, similar to the ordinary elements on the periodic table, a new theory suggests.

Mysterious signals from 'hell planet' 40 light-years from Earth could finally be solved by James Webb Space TelescopeThe hellish super-Earth '55 Cancri e' may be constantly losing and re-growing its atmosphere, a new study of the planet's strange transit signals suggests.

Ultra-powerful plasma 'blades' could slice entire stars in half, new paper suggestsStars could be sliced in half by "relativistic blades," or ultra-powerful outflows of plasma shaped by extremely strong magnetic fields, an unpublished paper claims.

Nuclear 'pasta' cooked up by dead stars could unravel the secrets of stellar afterlifeIn the extreme hearts of neutron stars, fundamental particles are twisted into strange 'pasta' shapes that could reveal untold secrets about how dead stars evolve.
-
'Ghost' particles from the sun could lead us straight to an invisible trove of dark matterNew research suggests that the sun may hold dark matter in its fiery heart, and ghostly particles called neutrinos could lead us to it.

'Twisty' new theory of gravity says information can escape black holes after allEinstein's theory of relativity say black holes are 'bald', but a new tweak to his research may give the mysterious objects their long-sought 'hair.'

Dark matter could be building up inside dead stars — with potentially explosive consequencesInvisible dark matter may be gathering in the ultra-dense innards of neutron stars, potentially causing them to detonate in massive explosions.

Giant 'bubbletrons' shaped the forces of the universe moments after the Big Bang, new study suggestsMeet the 'bubbletrons' — theoretical particle accelerators that may have helped build the universe as we know it.

Invisible supernovas called 'bosenovas' may be exploding all around us, new research suggestsWhat happens when an invisible star dies? It erupts in an invisible explosion, of course. New research describes how these unseen 'bosenovas' may behave.

Scientists think they saw an asteroid crash into a dead star — and release one of the brightest explosions in the universeAstronomers proposed a new mechanism behind mysterious fast radio bursts (FRBs), and it involves unlucky asteroids crashing into neutron stars.
