    Data
In summary, the conversation discusses the recent findings from the WMAP (Wilkinson Microwave Anisotropy Probe) mission. Pages 48 and 49, along with figures 20 and 21, suggest a new best estimate for Omega at 1.04, which is higher than the previous estimate of 1.02. However, this cannot be confirmed and further research is needed. The mentioned press release and additional pages provide more information on the topic. A graphic timeline is also mentioned as a useful resource for understanding the findings.

pages 48 and 49
figures 20 and 21

I can't say definitely but it looks like a new best estimate is emerging for Omega, which now might be more like 1.04 than the old figure of 1.02.

Cant be sure about this, see for yourself.

here is a press release, couldn't get much out of it though
http://map.gsfc.nasa.gov/m_or/PressRelease_03_06.html

here is another page for general audience, more stuff here
http://map.gsfc.nasa.gov/m_mm.htmlHEY THIS GRAPHIC TIMELINE IS KIND OF NICE

Related to New WMAP Data: Check Out Figures 20 & 21 on Pages 48 & 49

1. What is WMAP and why is it important?

WMAP (Wilkinson Microwave Anisotropy Probe) is a NASA satellite mission that mapped the cosmic microwave background (CMB) radiation in the universe. This data is important because it provides insight into the early universe and helps us understand the origin and evolution of the universe.

2. What is the significance of Figures 20 & 21 in the new WMAP data?

Figures 20 & 21 show the CMB power spectrum, which is a graph that represents the intensity of radiation at different angular scales. This data is significant because it helps us understand the distribution of matter and energy in the early universe.

3. How was the data for Figures 20 & 21 collected?

The data for Figures 20 & 21 was collected by the WMAP satellite using a specialized instrument called a radiometer, which measures the intensity of microwave radiation in different directions in the sky.

4. What do the peaks and dips in Figures 20 & 21 represent?

The peaks and dips in Figures 20 & 21 represent fluctuations in the intensity of CMB radiation. These fluctuations are caused by variations in the density of matter and energy in the early universe.

5. How does the new WMAP data support the Big Bang theory?

The new WMAP data provides strong evidence for the Big Bang theory by confirming the predictions made about the CMB radiation. The data also supports the idea that the universe is expanding and that it has a flat geometry, as predicted by the theory.
