Journalism

While the interest for communicating science in the written form has always been with me, it became a profession in 2015 when I started working for IFLScience. In the last two years, I’ve produced more than 1,500 articles mostly on space and physics which are my areas of expertise and also on medicine, archaeology, and social sciences. I’ve also written about astronomy for Italian publications such as the Corriere Della Sera

Below are a couple of pieces from IFLScience that I’m particularly proud of, and a selection of blog posts from The Astroholic. 

From The Astroholic

I recently talked about how time travel to the past is unlikely to be possible. That came with the label that we haven't found a law that tells us that it's impossible just yet. We have hints, but no certainty. So what if time travel was suddenly possible? Who should be using it? For what reason? And with what limits? Let's...
What does it actually look like in the asteroid belt? Is it anything like as dense as is shown in films? Or is it more like you can see one or two rocks in the distance? Matthew, Amsterdam Contrary to popular belief, the asteroid belt is mostly empty and it's not the crammed zone of potato shaped rocks seen in films...
For all intents and purposes gravity travels at the speed of light but it is very hard to measure, and so far we have no direct model-independent measurement of the speed of gravity. Physics has to main gravitational models: Newtonian dynamics and General Relativity The Newtonian gravitational model assumes that the gravitational interaction is instantaneous, and we know that this is...
Sometimes inspiration strikes in unusual ways at unusual times. I was tagged in a quote tweet where Prof Peter Coles states that as an astrophysicist he must contest Prince Harry's statement that "the stars were aligned when he met Meghan." Now, I'm currently on my honeymoon in New Zealand and we are waiting at the Rotorua airport for a flight...
If by big we mean physical dimension, the largest known galaxy is most likely IC1101. IC1101 is gargantuan even among galaxies; it's a super elliptical galaxy with a diffuse stellar halo that to extends to at least 1.4 million light years. The Milky Way's halo by comparison extends to about 100.000 lights years. In the picture we see an artistic rendition of...
A few years ago I filmed a vlog ranting about Astrology being nonsense and I'm now revisiting the subject, not because something has changed (it's still bullshit), but because I think I understand my anger a bit better. A discussion arose in work concerning the most annoying unfounded beliefs that people have. Antivaxxers are by far the most despised category,...

Colliding stars

I know that likelihood of stars colliding is very low, but have there been papers describing the theoretical process of star collision? James, London I think we can divide star-collision into three classes: Stellar Mergers Binary collisions Stellar Collision Under the stellar merger label we include the theoretical stars which are formed in tightly bound clusters and in their infancy merge to form very massive...
The Sun is responsible for all life on Earth and most of our planet's means of energy production depends on the Sun. We are told that without it we cannot survive, or at least told that we can't survive for very long. My question is just that: how long would we survive? Our thought experiment starts with an unphysical event....
Last night I had a nightmare that the centre of London was nuked. In my half-sleep state I tried working out if I could survive just by getting under my mattress or if I had to get out of bed to be more proactive for my survival. First, I had to check what kind of bomb could detonate in Piccadilly...
Dear Mr Science Guy, How many calories would get in a bottle of antimatter? How long would it take to burn off at the gym if you drank it? Thank you, Rob, age 30 Rob asks a very interesting question which allows me to explain several different concepts. First of all, what is anti-matter? Anti-matter is a substance composed of anti-particles, which have the...
