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.

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...
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...

Can anyone hear us?

Assuming that there are other intelligent civilisations out there in the universe, what is the likelihood that we'll ever be able to communicate? The key to answer this question is to look at the Drake Equation. Where N is the number of civilisations in our galaxy with which radio-communication might be possible (i.e. planets past our light cone); The DE tells...

If the 1st Law of Thermodynamics is true how could the Universe begin from nothing? To answer this question we need to remember that nothing is a global term and not a local one. Vacuum states exist where there is no matter or energy (they have maximum entropy) and they are, as we can understand them, empty. Those are their global characteristics....

Stars of the Future

If the universe continues expanding forever, how long until it's too diffused to allow star formation? How many generations of stars will that mean the universe has? How will the elemental make-up of these late stars be different and what effects will that have? I can't give you an exact timescale but it's possibly trillions of years in the future....
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,...
