Jupiter is sometimes referred to as a failed star, too small to achieve nuclear fusion. If a Neptune sized planet crashed into Jupiter would it be big enough to be a star then and give us a small second star in our solar system?

If a photon is a &quot;particle&quot; that is all energy and without mass, is there an equivalent &quot;particle&quot; that is all mass and without energy? Posted: 22 Jan 2016 10:28 PM PST <!-- SC_OFF --><div class="md"><p>Moreover, is there anything about our &quot;observable universe&quot; in that our ability to &quot;observe&quot; is inherently dependent on energy, such that if a &quot;particle&quot; is all mass and <em>without</em> energy we are unable to &quot;observe&quot; it?</p> </div><!-- SC_ON --> submitted by

Spectrometry question: inverted peaks and detection in salt water? Posted: 23 Jan 2016 04:46 AM PST <!-- SC_OFF --><div class="md"><p>Hello askscience, I&#39;ve been having a couple problems running my substances in the spectrophotometer. I&#39;m reading <strong>dihydrostreptomycin sequisulfate</strong>, that will be used in a toxicity study. It forms nice peaks in the ultra pure water around 190-210nm, even though high concentrations don&#39;t seem to have a good correlation to concentration (I imagine it as a inverted bell), but as I&#39;ll be using low concentrations it is not a problem. When I read in the F/2 medium (made of saltwater, metals and EDTA) there&#39;s an inverted peak around 200 and several small peaks around 190nm that look like noise. I tried to change the pH and add more EDTA to chelate the metals but there&#39;s no answer. I found some articles about making a reaction to read it around 400nm, but I don&#39;t have the reagents in the lab and it would be very difficult to make it during the toxicity test. Any idea what I could do to get readable peaks?</p> </div><!-- SC_ON --> submitted by

Does human blood really travel 12,000 miles every day? Posted: 22 Jan 2016 01:56 PM PST <!-- SC_OFF --><div class="md"><p>Someone posted that on Facebook and I thought it was total bullshit. So I <a href="https://www.google.com/webhp?sourceid=chrome-instant&amp;ion=1&amp;espv=2&amp;ie=UTF-8#q=how%20far%20does%20blood%20travel%20in%20a%20day">Googled it</a> and it seems it&#39;s not bullshit? I guess my real question then would be: isn&#39;t there something more to this? That&#39;s 500 miles per hour. I can&#39;t understand how that wouldn&#39;t rip your body apart.</p> </div><!-- SC_ON --> submitted by

Planet orbits, can a solar system ever have 2 planets with opposing orbits? Posted: 22 Jan 2016 10:40 AM PST <!-- SC_OFF --><div class="md"><p>I know that planets themselves can spin in different ways (uranus spins perpendicular to all other planet rotation) but can a solarsystem that is being formed have one planet orbiting clockwise, and another planet further away orbiting counter clockwise?</p> <p>can we have a solarsystem that has all the planet orbiting in a counterclockwise orbit or is there something within the atoms and bonds that forces everything to go in 1 uniform rotation?</p> <p>sorry if i used the wrong terminology when describing my question.</p> </div><!-- SC_ON --> submitted by
