If you believe something exists, and may even have some reasonable circumstantial evidence that it exists, yet have no concrete, physical proof; it doesn't exist. Right?

Do we have concrete, physical proof that electrons exist?

Do we not? Are you saying there's no way to prove they do?
Confused o-O

I don't know. The evidence I can think of is indirect. But I'm not much of a physicist at all. Probably Emma or RJ or someone else would know.

But if we don't have concrete physical evidence of them, I think by the logic of your statement/question, then WE don't exist. Or anything else.

Holy cow, Morgan Freeman is talking about this stuff on the Craig Ferguson show right now!

Not for another hour here, then, but now I'll stay up.

Morgan Freeman? Yeah, I see he's on the schedule.

You're sure it's not Neil deGrasse Tyson, though? That would make more sense.

Oh, except that Morgan Freeman is God.

Are you tricking me into staying up late for nothing?

Except of course listening to Morgan Freeman's voice?

That's because Morgan Freeman narrates the Into The Wormhole series on the Science Channel ( And yes, the electron has been seen.

That's a really interesting program, BTW. I used to show part of it to my physics kids when we'd talk about theoretical physics.

I've watched every episode....
For fun.

@BadAstronomer (Phil Plait) says dark matter exists, so that must be true. He also says dark energy exists, "But we don't know what the heck this stuff is." He writes some fun stuff about both, mostly for Discover & Slate. There's some very recent stuff, too.

Anyone who is interested in anything about astronomy and who uses Twitter really ought to follow @BadAstronomer.

The plasma physicists seem to be able to explain things with electrostatic attraction without using weird energy and matter that we can see no signs of, except in the expansion rate of the universe.

Theoretical physicists discover new properties of or universe with math. It usually takes 4 or 5 decades later for us to develop the technology to actually validate it.

Aren't dark matter theories about that old, now, though?

I tripped over some this morning.

His house runs on dark energy. All he has is darkswitches.

You can't see dark matter with light.

That's just short visible frequency and uv wavelengths.

Your killing jokes with science.
Isn't that illegal in California?

Judging by some of California's laws it seems jokes kill science down there...

Maybe not in the form we imagine when we first learn of the theory, but something we can't see seems to be hogging up a whole lot more of the universe than the stuff we can see. I'd prefer a new theory of gravity though, one that actually explains it AND leads to my new pair of anti-grav boots.

Helpful hint: moon shoes are a poor replacement.

How do you create something from nothing? 1 - 1 = 0. The divergent separation allows both to exist while time separates them.

Scientists in this field, make a very intriguing argument.
I've been reading and watching videos on it.
I find this sort of thing interesting.
Math too......

How the hell was I popular in high school?
I'm kind of a nerd.

Actually it's 1+ -1 = 0
0 represents the opposite force of gravity keeping things in place as the gravitational pull has been shown to be too weak to do it alone.
1= gravitational pull
-1 = dark matter or dark energy
Canceling each other out.
It's just a theory.

You can create a lot of things if you balance the equation. Futurama (the show) got it right when they went forward in time enough to go to the past. You create time and matter from nothing if you split the equation right.

The theory is, that the energy is already present.
Dark energy.

Guys, I'm not an expert on this, just fascinated by it.

Tilton, are electric and magnetic fields tied together directly? Why is there a time delay for magnetic flux to evolve? Why are we taught knowledge on this that is more than 100 years old?

TiltonAllStarz Outside Ur Comfort Zone

I'm going to answer those questions with the most scientific, logical information I have: no clue.
If you have some knowledge on this, feel free to share.
I'll listen.

One more question. Why do permanent magnets appear to give off endless streams of energy. You can construct a magnet motor that keeps spinning if you like. Or continuously hold up mass against gravity.

No clue. Haven't studied this stuff at all. Answer subject to change!

It's a theory in theoretical physics right now.
