What I am about to explain to you may be a bit confusing unless we begin with what the heck a ‘quasar’ is.
A quasar is defined as an extragalactic, super massive star-like object in that it is luminescent, but that it is the most luminescent object in the universe.
A pulsar, however (and yes, they have been found which is awesome!) is a quasar that acts sort of like a lighthouse: it blinks in a rotating fashion. However, scientists have not yet figured out exactly how this works.
But what they have found out is that some molecules actually do blink.
According to an article from August 12th, last week Neils Bohr’s prediction of molecules blinking was correct after all.
Neils Bohr had predicted this long ago, as a chemical physicist. Now physicists have found that molecules can blink due to a transition of electrons between discreet levels of energy within individual atoms at a time.
These have been coined ‘Quantum jumps’ by Neils Bohr and they have finally found how exactly this works. There are discreet interruptions when the electrons are being transferred, and so the molecules actually light up with energy when all the electrons are in it, then when the interruption is gone they all then go to the other molecule. The interruptions are caused by the emissions (of carbon and such) from the atom, blocking out the electrons.
What’s cool is that these are molecules that are blinking here. What it means is, different ways of imaging for cancer. Real time images of viruses such as HIV and soforth.
But not only for medical professionals: if blinking molecules could be controlled (which may be coming sooner than we know it), these could be used as an electricity-free way to use house-hold lights, brighter display screens on computers and gaming systems, TVs, and could change the way we see electronics as we know them.
As far as novae go, I wanted to explain why you can’t see quasars, pulsars, or supernovae (or novae) with the naked eye.
The problem is this: the closest stars to us besides the Sun take a loooooooong time to send their light to us.
If we were very close to the supernova or pulsar or quasar or whatever it is, we could see it in real time, or close to it.
But in the same way, you cannot see supernovae or quasars with the naked eye because they are so far away, that by the time the light gets here it would barely be noticeable. Any star that is massive enough to have a supernova (or a nova, which is a supernova that causes a white dwarf not a black hole), or any pulsar or quasar, is not even close to being seen with the naked eye. You even need a telescope to see all of the separate areas and craters on the moon, let alone a supernova that’s happening a thousand thousand thousand thousand thousand million light years away.
Next post: The ending of “The Time Machine” (contains spoilers!) and how probable the ideas really are about what the future will be like…
Mind posting a link to that article? I'd like to check it out. Sounds fascinating.
