It is an awesome exclusive product for discovering your spiritual animal and the clues it has to your future success without the normal expense.

MarakanaCacak1989 The cosmic background fluctuations were captured by the COBE (cosmic background explorer) satellite. Cosmic background is basically old light yes, and that light traveled long distances to reach cobe. What happens when light travels long distances is that it's wavelength changes through space. So scientists look at the sky with cobe and capture a lot of kinds of wavelengths, but they know what wavelength to expect and what not to... And they map the cosmic background. Anyway, if you want a suggestion to read more about stuff being explained from the very basics go take a look at Stephen Hawkings books "a brief history of time" and "the universe in a nutshell "

Please someone answer this question if you can. If this light was released a few hundred thousand years after the big bang, how did we (our matter) get to where we are now, before this light reached us? The universe doesn't expand faster than light does it? If it did the light would never reach us. Wouldn't we have to out run it for some of the 13 billion years then slow down for it top catch us up? Which I know doesn't make sense.
@finlarg
@finlarg 9 жыл бұрын
Let me try to (partially) answer your question. You seem to imagine that we are at a 'location' where we weren't in the past. On the large scale (galactic supercluster level) we aren't moving and haven't moved - much. The expansion of the universe is the expansion of space, not specifically objects moving apart - even though it seems that way. This means that there is no central point in the universe. Everything on a large scale, appears to be moving away from us, so it SEEMS like we're in the middle, but if you were to go to a galaxy 10 billion light years away in any direction you choose, it would look the same. You'd still appear to be in the middle. The universe appears to be spherical, with us at the centre. But, due to the finite speed of light, you could never get to the 'edge' - not even theoretically. As for the universe expanding faster than the speed of light (c), think of it this way: Nothing can move past another thing faster than c. But picture a galaxy 5 billion light years away, moving away from us at 55% of the speed of light (this might not be an accurate figure - I'm going from memory) relative to us. Now imagine that a galaxy 10 billion light years from us is moving apart from the first galaxy at 55% the speed of light. Add the 2 velocities together and you get 110% of the speed of light - which should be impossible. But it's not, because nothing on a local scale is moving apart at more than 186 thousand miles per second (c). It's the SPACE which is expanding, and the accumulation of sub c velocities (on a large scale) CAN exceed c. This is why we estimate the size of the universe to be some 90 billion light years across, not 2 x 13.8 billion, which you might expect. Just remember that it's the SPACE which is expanding!

but i cant understand how that photon is able to reach us also i dont think that that photon can exceed speed of light bcoz it will require very high energy and extremely low mass as E=MC2 then c= sq root of E/M
@finlarg
@finlarg 9 жыл бұрын
Deepanshu Gajbhiye You're mistaken to think of 'that photon'. Photons are continually streaming from all stars and galaxies. When we look at a galaxy which is 10 billion light years away, we are seeing it as it appeared when it and the universe were only 3.8 billion years old. All of the photons it emitted after that point, haven't reached us yet. In the far future, it will disappear from sight, because of the expansion of the universe. This does not mean it has ceased to exist, but it means that the expansion we talked about before has caught up with us.

This, yes, THIS! 1. Does the CMB have a rest frame, and are we moving relative to it? (Possible dipole explanation, but it breaks everything else...) 2. COBE -> WMAP -> Planck -> ??? What's next in exploring the whole-sky CMB? 3. What have we learned (since BICEP2) about E-mode and B-mode CMB polarization? Will this finally end all talk about cosmic strings? 4. Does CDM have any imprint on the CMB? If so, what is it and where is it? If not, why not, and what does it tell us about possible CDM candidates? So many fundamental questions!

It's using the Mollweide map projection, it exists to enable more accurate proportions (so one area on the map of a certain area should have about the same mapped area as any other), at the expense of being less accurate in terms of shape. It is of course possible to map the data to any map projection, but using one that favours proportions over shape makes a little more sense in this case because it makes it easier to compare different spots.

Also note (can't remember if he said this in the video) that the Celsius scale scales the same way the kelvin does, so the unit "Kelvin" \\Is the same as\\ the unit "Degrees Celsius", only with different datums.

I have a hard time figuring out how they can read temp differences at, for example, 1 light year out, 2 light years out, 3, 4, etc all the way to the edge of the observable universe, and in every direction. Then to place this info on a simple 2D map. Or are the measurements only taken at the outermost limit?

Most photons can xfer heat in some way, depending on the material (I'm glossing over a lot due to char limit): Microwave (and some RF): EM dipoles in food rotate to align with fluctuating EM field, called dielectric heating. Also see ion-drag. Infrared: causes vibrations in the molecules. Visible/UV: typically absorbed by electrons, then can be re-emitted at lower energies to xfer heat. Microwaves are nice because they can penetrate deeper into food. Also note they run at high energy: ~1 kW.

I'm going to preface by saying I worked closely with GPS for a few years. Corrections are made for clock accuracy and relativity. The clocks on GPS satellites are very accurate. They are more accurate than any clock on the receivers. This, and the difference in relative speed and the great distance between the user and the satellite necessitate clock corrections. So, it is special relativity, general relativity, and clock technology that necessitate corrections in GPS. Also, great video!
