There are many competing theories about the ultimate fate of the universe. Physicists remain unsure about what, if anything, preceded the Big Bang. Many refuse to speculate, doubting that any information from any such prior state could ever be accessible. There are various multiverse hypotheses, in which some physicists have suggested that the Universe might be one among many or even an infinite number of universes that likewise exist.

This first global map of ocean surface saltiness, released in September 2012 by the NASA Aquarius mission team, shows the distribution of salt in the first 2 cm of the Earth's ocean. Salinity variations are one of the main drivers of ocean circulation, and are closely connected with the cycling of freshwater around the planet. High salinity is seen in the Mediterranean, Atlantic, and the Arabian Sea. Image courtesy of NASA/GSFC/JPL-Caltech

tdarnell's Channel This channel is dedicated to Space Fans who love astronomy and want to learn concepts and hear about new discoveries in astronomy. I try to present these concepts in a way that provides some perspective of the importance of astronomy in our daily lives. DeepAstronomy is now an iTunes podcast.

Through the Wormhole: Is There an Edge to the Universe? It is commonly theorized that the universe began with the Big Bang 13.7 billion years ago. But since we can only see as far as light has traveled in that time, we can't actually make out the edge of the universe. Could it be that the universe is infinite? Is there any way to find out what the shape of the universe really is? Can we find the edge, discover what might lie beyond it, and perhaps even discover a universe next to ours?
This web page is designed to give everyone an idea of what our universe actually looks like. There are nine main maps on this web page, each one approximately ten times the scale of the previous one. The first map shows the nearest stars and then the other maps slowly expand out until we have reached the scale of the entire visible universe. Visits since 1 Aug 2000:
Missions Missions The National Aeronautics and Space Act of 1958 (Space Act) established NASA as an aerospace research and development agency that sponsors and conducts flight missions to obtain data in furtherance of its objectives. In NASA's Science Mission Directorate (SMD), flight missions range from suborbital projects—including balloons, sounding rockets, and airplanes—to interplanetary probes and flagship observatories.
Through the Wormhole: How Does the Universe Work? With the help of massive machines called particle accelerators, scientists studied the subatomic realm and made discoveries about the forces that operate at that level. But the search for a comprehensive explanation still continues. In particular, physicists have sought to find a way to reconcile Einstein's model of space-time, which seems to work best when applied to big objects like stars and galaxies, and the theory of quantum mechanics, which offers an explanation of electromagnetic and nuclear forces that makes sense of reality at the tiniest level.
Exploring the Universe
All I ever have to do to prove that is just set up a telescope on a sidewalk somewhere, anywhere, and people will gather around in no time. A miniature crowd develops full of questions; a little sea of pent-up curiosity that has finally found an outlet. It's not all that surprising though, is it? Most of us have an innate curiosity about the planet we live on and the universe surrounding us. It never fails that someone will walk up and ask me a question that's been on their minds for years, and heave a great sigh of relief. "Wow, that's amazing." or "See, I knew it!".
