The Holy Grail of Planetary Astronomy: The Search for Earth's Twin
Michio Kaku is a futurist, popularizer of science, and theoretical physicist, as well as a bestselling author and the host of two radio programs. He is the co-founder of string field theory (a branch of string theory), and continues Einstein’s search to unite the four fundamental forces of nature into one unified theory. He holds the Henry Semat Chair and Professorship in theoretical physics and a joint appointment at City College of New York and the Graduate Center of C.U.N.Y. He is also a visiting professor at the Institute for Advanced Study in Princeton and is a Fellow of the American Physical Society.
Kaku launched his Big Think blog, "Dr. Kaku's Universe," in March 2010.
Every Wednesday, Michio Kaku will be answering reader questions about physics and futuristic science. If you have a question for Dr. Kaku, just post it in the comments section below and check back on Wednesdays to see if he answers it.
Today, Dr. Kaku addresses the following question:
A recently discovered planet named Kepler 22b apparently has a very, very similar composition to Earth, although I don’t think they have it exactly figured out yet. What do discoveries like this mean and what is the possibility of many other earth-like planets being out there?
Watch Dr. Kaku's response here:
New research links urban planning and political polarization.
- Canadian researchers find that excessive reliance on cars changes political views.
- Decades of car-centric urban planning normalized unsustainable lifestyles.
- People who prefer personal comfort elect politicians who represent such views.
It turns out the human scalp has an olfactory receptor that seems to play a crucial role in regulating hair follicle growth and death.
- Scientists treated scalp tissue with a chemical that mimics the odor of sandalwood.
- This chemical bound to an olfactory receptor in the scalp and stimulated hair growth.
- The treatment could soon be available to the public.
Science and the squishiness of the human mind. The joys of wearing whatever the hell you want, and so much more.
- Why can't we have a human-sized cat tree?
- What would happen if you got a spoonful of a neutron star?
- Why do we insist on dividing our wonderfully complex selves into boring little boxes
