Some say that the reason you can’t travel faster than light is that your mass will increase as your speed approaches light speed – so, regardless of how much energy your star drive can generate, you reach a point where no amount of energy can further accelerate your spacecraft because its mass is approaching infinite.
Since the late 20th century, astronomers have been aware of data that suggest the universe is not only expanding, but expanding at an accelerating rate. According to the currently accepted model, this accelerated expansion is due to dark energy, a mysterious repulsive force that makes up about 73% of the energy density of the universe.
One of the most promising materials in science could answer some questions about one of the most elusive particles in the universe, according to a new paper. A trio of Spanish physicists believes that graphene, that simple, special Nobel-winning stuff, could provide some key insights into the behavior of the Higgs boson.
Huge volcanic eruptions caused the largest mass extinction in history, scientists believe. The last Permian extinction, also known as the Great Dying, devastated life on Earth when it took place 250million years ago. It saw 95 per cent of sea life wiped out and 70 per cent of animals on land killed.
The beautiful Andromeda Galaxy (M31) is a spiral galaxy a mere 2.5 million light-years away.
The black hole in the nearby galaxy M87 weighs in at 6.6 billion suns, making it the local universe’s heavyweight champ.
