One of the big problems many of us non-techies have with the science cognoscenti is that they easily blow off legitimate questions with a pat on the head and 'please go away' attitude. Drakkith - we do not know what Dark Energy is because it is well, unknown. I asked a legitimate question...

Ok, this question is prompted by watching a TV program on the Big Bang - sorry! Right after inflation, there was a flood of matter/anti-matter. The matter/anti-matter went through a period of annihilation but there was a residual amount of (anti-)matter left that has become our physical...

I once watched a beautiful Golden Eagle land with a wing crossed over a transmission line and its other wing on the spreader. The eagle immediately combusted and caused enough damage that PG&E had to look at the tower from one of its helicopters. It was always my understanding that birds do not...

The recent publishing of the Event Horizon Telescope's fantastic accomplishment vis-a-vis the imaging of a black hole sometimes refers to the capturing of 'photons'. Is any emission in the electromagnetic spectrum considered a photon? As an amateur visual astronomer, I am familiar with the...

ed Pardon my impertinence, but doesn't anything shorter than the length of Planck Time foreclose knowing what happened at the moment of the Big Bang.

Thanks to both of you. I am absolutely certain the article I am trying to find was not about a space vehicle remnant. The description of 2010 TK7 meets my estimated time frame but my recollection is slightly different (and likely wrong :frown:). I remember the object as being in the 'same'...

A bunch of years ago, I read about a very small object following Earth in the same orbit, but not in any danger of collision with Earth (at least in the next few billion years). Anyone know about the object. I have done a search but cannot find any reference to what I think I read about?

Head is hurting - So, we don't have a singularity, or maybe we do, that contains or doesn't contain everything in an infinitely tiny kernel that magically goes through an inflation turning into all of the Standard Model particle that was not hot a very small period of time before but is then...

I apologize for my strong headedness - but there must have been something that heated before something was reheated. What was 'inflated' if not a something some call a singularity.

No, I was trying to understand how the singularity has any temperature whatsoever and why DURING the inflation the temperature rose to trillions of degrees of heat. I understand (at least I think I do) how the growth of the universe both spatially and time wise cooled down to the current ±...

(I am not a physicist - so, please be gentle :redface:) I was watching a program last night on the SCI channel, Did the Big Bang Really Happen? and they were describing the 'Singularity' as being this super hot very dense and infinitely small thing. And then when it went through the 'inflation'...

I would like to add M33 - The Triangulum Galaxy. I have glimpsed this very sparse and wide fuzzy from the Santa Crus Mountains outside of Boulder Creek. It is very difficult and you must know where to look.

I actually became a licensed General Building Contractor in 1978, before building my first home and I managed the design of every project I built. No one would consider me a DIYer. 25 houses with sales prices in excess of $500,000 in 1984-1990 Dollars without administrative complaint or...

In an article I read, they did not see the same movement in the southern magnetic pole. https://www.theatlantic.com/science/archive/2019/01/north-pole-moving-shutdown/580330/ I, too have a question about the magnetic Earth flipping its magnetism orientation. But a generalized read is here...

All told, I do not disagree with both of you comments. Just offering my take.
