What is Big Think?  

We are Big Idea Hunters…

We live in a time of information abundance, which far too many of us see as information overload. With the sum total of human knowledge, past and present, at our fingertips, we’re faced with a crisis of attention: which ideas should we engage with, and why? Big Think is an evolving roadmap to the best thinking on the planet — the ideas that can help you think flexibly and act decisively in a multivariate world.

A word about Big Ideas and Themes — The architecture of Big Think

Big ideas are lenses for envisioning the future. Every article and video on bigthink.com and on our learning platforms is based on an emerging “big idea” that is significant, widely relevant, and actionable. We’re sifting the noise for the questions and insights that have the power to change all of our lives, for decades to come. For example, reverse-engineering is a big idea in that the concept is increasingly useful across multiple disciplines, from education to nanotechnology.

Themes are the seven broad umbrellas under which we organize the hundreds of big ideas that populate Big Think. They include New World Order, Earth and Beyond, 21st Century Living, Going Mental, Extreme Biology, Power and Influence, and Inventing the Future.

IMAX Hubble 3D & the James Webb Space Telescope

IMAX Hubble 3D, hitting the theaters on March 19, features the most famous space telescope of all, the Hubble, launched in April 1990. Soaring above the earth's atmosphere, it gives the clearest picture of the universe without atmospheric disturbances.

Astronauts were sent to service the telescope on five separate missions, the last in 2009 and the most ambitious. Without these delicate but dangerous space repairs, the Hubble would have been a piece of useless space junk.

This movie chronicles one of these space missions.

Judging by scientific citations in science journals, the Hubble is perhaps the most cited scientific instrument of all time.

Besides giving us spectacular photographs from space, it has given us:

  • Proof of the existence of black holes lurking in the center of galaxies
  • The most complete life-history of stars, from star formation to supernova
  • The most detailed photographs of the planets besides photos from space probes
  • The most detailed photographs of comets, asteroids, and galaxies
  • Evidence for the existence of dark matter, and also proof of Einstein's theory of relativity

Rescuing the Hubble in 2009 was very risky, since astronauts could not safely flee to the International Space Station (ISS) in case of trouble, but it was successful.

The repairs should last until 2014, when the telescope will be decommissioned. It will be replaced by the James Webb Space Telescope (JWST).

According to NASA - The new telescope has a 6.6-meter diameter primary mirror and has a 25-square-meter collecting area formed from eighteen hexagonal segments. Comparable to the Hubble Telescope, the JWST collecting area is about 6 times larger giving it much more light-gathering power. It will primarily operate in the infrared but will have some capability in the visible range as well. The JWST will also operate much further away than the Hubble Telescope. To give you an idea, Hubble currently orbits the Earth at about 570 kilometers. The JWST will be operating at approximately 1.5 million kilometers from Earth at the second Lagrange (L2) point and will be launched on an Ariane 5 rocket.

It will be interesting to see the stunning imagery from the Webb Telescope once it's in operation but we will of course have to wait until mid-decade or so.

Don't forget to go see IMAX Hubble 3D hitting the theaters on March 19!
