The 2020 Nobel Prize in physics was awarded to three scientists – an Englishman, an American and a German – for breakthroughs in understanding the most mysterious objects in the universe: black holes.
There is a reason why it’s easier to roll marbles down rather than up a hill. And the answer (to this and to gravity itself) is all about acceleration.
Martian meteorites allow scientists here on Earth to decode that planet’s geology, more than a decade before the first missions are scheduled to bring rocks back home from Mars.
The distance between the ISS and Earth is the same as about 3,850 football fields. To bring the station down, rockets will lower it a bit, and then gravity will send it crashing the rest of the way.
Researchers have made some of the most accurate clocks imaginable in recent years, but the trick is harnessing those clocks to electronics. Using lasers to tune microwaves bridges the gap.
Why do astronomers believe there’s dark matter when it cannot be directly detected? Let’s look at the evidence, and see what dark matter’s presence means for our universe.
In the fourth episode of our podcast series, we look at the practical, legal and ethical questions about going to set up base on the moon – and mining its resources.
Compared to Earth, more “oomph” is required to bring magma to the surface of Mars, and this is probably why we haven’t seen any recent eruptions on the red planet.
If you fall one storey, dust yourself off – you’ll be fine. If you fall seven storeys: sorry, but you’ve probably got about 2 seconds to prepare to meet your maker.
