Isn’t the FLRW metric way generic? It lays out the basic assumptions and tells us how the universe should behave, but it doesn’t say WHAT the universe is made of.

The flow of ice at Pine Island Glacier in West Antarctica has sped up dramatically due to the disintegration of the ice shelf in front of it, and this could lead to faster sea level rise

Many different bird species have been affiliated with the Seattle Seahawks’ mascot, but none is technically a “seahawk”

When we exercise more, our bodies may compensate by using less energy for other things – especially if we eat less too

Sometimes humans get ahead of ourselves. We embark on grand engineering experiments without really understanding what the long-term implications of such projects are. Climate change itself it a perfect example of that - no one in the early industrial revolution realized that, more than 100 years later, the emissions from their combustion engines would increase the overall global temperature and risk millions of people's lives and livelihoods, let alone the impact it would have on the species we share the world with. According to a new release from the Salata Institute at Harvard, we seem to be going down the same blind path with a different engineering challenge in this century - satellite megaconstellations.

You might think galaxies can’t ever find each other in our runaway cosmos, but it turns out gravity can sometimes overcome even the stretching of space itself

ESA astronaut Sophie Adenot is preparing to launch to the International Space Station for her first space mission: εpsilon.

After years of intensive training — from emergency procedures to spacewalk simulations — the countdown has begun. Flying alongside astronauts from NASA and Roscosmos, Sophie will join an international crew living and working together in space.

Aboard the ISS, Sophie will live and work in microgravity, conducting scientific research and performing a range of European- and French-led experiments that advance knowledge for life on Earth and in space.

Join us live on YouTube to watch the launch of Sophie Adenot.
