Getting out of a black hole

We picture black holes as mighty beasts that will inevitably engulf everything around them, not even light has a chance to escape.
However, a few scientists have claimed that black holes actually aren’t so black so to speak. Dr Stephen Hawking, for instance, claims that some things can indeed come out and that radiations could be observed as if coming out of a black hole. So here it is, our topic on what goes out of a black hole.

EDIT: we made a little mistake in the second panel, the mass of a black hole is finite (about a few solar masses for black holes originating from collapsed stars) but the gravity within the horizon is infinite.
EDIT 2: Mistake corrected 🙂

The Vikings in the Americas

The Vikings are the first Eurasians to have “discovered” the Americas.

The Vikings, these fierce sailors, had set foot on the East coast of the Americas well before Christopher Columbus did. Regularly, we hear stories that others before them did it such as the Arabs or the Chinese via the west coast. At Sci&Fi, we only believe what we see, and in this case only the Vikings left an indisputable archeological proof of their visits: l’Anse aux Meadows. From their tales (named the Sagas), we also know how they named this land, the Vinland (the land where vines grow). The most amazing part in all of this is that these events happened more than a thousand years ago! See for yourself

Surtsey’s suspended fate

Have you ever wondered what happen to volcanic islands that rise from the sea? Footage of their rising out of the ocean is always spectular but no one ever mentions what goes on next. Think things remain the way they are? You would be so wrong, so many slow processes occur. Actually, many of new volcanic islands never last long until they fall apart back on the seafloor or are eroded by the waves.

We’ve taken the example of Surtsey, which is a tiny island off the coast of Iceland in the Atlantic Ocean. It rose from the depths a bit more than 50 years ago but it has already been largely gnawed away by the ocean. Will it survive the erosion process? Scientists have studied it ever since its birth and only a study of its geologic evolution can answer this question. Have a look…

Europe’s only wild monkeys

Picture of a Barbary macaqueMan is not the only primate present in Europe. But would you know where to find the other one?
If you have ever been to the Rock of Gibraltar, in the South of Spain, you surely haven’t missed its main attraction, the macaques. If you have never been then know that these are the only wild monkeys present in Europe! Let’s explore in more details who they are…

Hello World

Sci&Fi in english - hello world

Hi everybody, Sci&Fi here.

We are science passionates and we would like to share our excitment about science with you !

For a while now, we have been maintaining a website in French sci-and-fi.com but we thought we would give it a try in English. This new version is just a trial for now, and depending on the feedback we receive we will continue (or not) to maintain it. As you may have noticed, our website is Sci8Fi (and not Sci&Fi) that is beause the name had been taken already, but it is an issue that will be dealt with over time. Anyhow, please let us know what you think, we’d love to hear from you ! You are more than welcomed to follow us on facebook, here, or leave a comment on the website or even send us an e-mail ( sci.and.fi.blog – at – gmail.com).

So ? What are we waiting for ? Let’s explore the past, interrogate the present and dream the future on Sci&Fi !

Sci&Fi, over and out.
