Fourth dimension (4-D):-

Scientists believe that the fourth dimension is time, which governs the properties of all known matter at any given point. Along with the three other dimensions, knowing an objects position in time is essential to plotting its position in the universe. The other dimensions are where the deeper possibilities come into play, and explaining their interaction with the others is where things get particularly tricky for physicists.
In geometry, the fourth dimension is related to the other three dimensions by imagining another direction through space; just as the dimension of depth can be added to a square to create a cube, the fourth dimension can be added to a cube to create a tesseract.

What if a black hole collided with a wormhole?

As long as a wormhole has a greater mass than any black hole it encounters, it should remain stable. If a wormhole encounters a larger black hole, the black hole may disrupt the wormhole's exotic matter enough to destabilize the wormhole, causing it to collapse and likely form a new black hole, Gabella said.

The larger a star is when it is created, the shorter its life will be! This is because larger stars consume their nuclear fuel (hydrogen) faster! However, even short-lived bright stars may last for a billion years. Our star, the Sun, is estimated to be 4.6 billion years old, but will remain relatively unchanged for another 5 billion years!

Traces of the gas phosphine point to volcanic activity on Venus. Last autumn, scientists revealed that phosphine was found in trace amounts in the planet’s upper atmosphere. That discovery promised the slim possibility that phosphine serves as a biological signature for the hot, toxic planet. Now scientists say the chemical fingerprint supports a different and important scientific find: a geological signature, showing evidence of explosive volcanoes on the mysterious planet.

What will happen if a black hole swallows a neutron star?

When a neutron star meets a black hole that's much more massive, such as the recently observed events, says Susan Scott, an astrophysicist with the Australian National University, "we expect that the two bodies circle each other in a spiral. Eventually the black hole would just swallow the neutron star like Pac-Man."
