Marcelo Gleiser
Theoretical Physicist
Marcelo Gleiser is a professor of natural philosophy, physics, and astronomy at Dartmouth College. He is a Fellow of the American Physical Society, a recipient of the Presidential Faculty Fellows Award from the White House and NSF, and was awarded the 2019 Templeton Prize. Gleiser has authored five books and is the co-founder of 13.8, where he writes about science and culture with physicist Adam Frank.
The best answer we have is, "Life is matter with intentionality."
Finding a tiny planet around bright stars dozens or hundreds of light-years from Earth is extremely difficult.
Scientists may have detected the somewhat smelly chemical dimethyl sulfide on a planet 120 light-years from Earth.
Looking at our planet with post-Copernican eyes has the power to change how we relate to it and each other.
A new book envisions an encounter of minds between the Argentinian writer Jorge Luis Borges, the physicist Werner Heisenberg, and the philosopher Immanuel Kant.
Life in the supremely vast cosmos is incredibly rare. We need a new vision for our living planet and for ourselves.
We should acknowledge that there are faith-based myths running deep in science's canon.
The multiverse pushes beyond the limits of the scientific method. From our vantage point in the Universe, we cannot know if it's real.
How are we to deal with the quantization of spacetime and gravity?
There is no such thing as a void in the Universe.
Fear of technology is not new. But we misunderstand its origin. In reality, we don't fear technology but each other.
Perhaps the whole Universe is the result of a vacuum fluctuation, originating from what we could call quantum nothingness.
We can reasonably say that we understand the history of the Universe within one-trillionth of a second after the Big Bang. That's not good enough.
We have become the greatest threat to ourselves and to life on this planet. We need a set of agreed-upon safeguards to preserve our future.
What began as an annoyance ended as a Nobel Prize-winning discovery about the Big Bang and the origin of the Universe.
Once the initial blaze of heat dissipated, the constituent particles of atoms were free to bind.
The acceptance of our cosmic loneliness and the rarity of our planet is a wakeup call.
What would become the Big Bang model started from a crucial idea: that the young Universe was denser and hotter.
For many years, some cosmologists embraced the idea of an eternal, steady state universe. But science triumphed over philosophical prejudice.
Einstein called his idea "abominable," but the world of physics came around to embracing the views of Georges Lemaître.
If the evolution of the Universe is a movie, what happens when we rewind it all the way backward?
Theory without experiment is blind, and experiment without theory is lame.
How scientists found out that we live in a cosmic aquarium.
Not even Einstein immediately knew the power of the equations he gave us.
Lonely humans will become infatuated with AI-fabricated personas.
It is a story with nebulous beginnings and no discernible end.
Though quantum mechanics is an incredibly successful theory, nobody knows what it means. Scientists now must confront its philosophical implications.
Experiments tell us quantum entanglement defies space and time.
To Einstein, nature had to be rational. But quantum physics showed us that there was not always a way to make it so.
