They weren’t actually tiny, they were about a metre long. But they do seem out of proportion.

They were very muscular and ended in very sharp talons, so pretty deadly.

I was trying to explain to an elderly friend that people don’t just phone other people now and certainly not at times they will be doing something.

She found it hard to accept that many people find it rude to be called unannounced.

As an example, at one time if someone was organising a social event (eg party) they would phone around to invite people.

But that’s incredibly rude you are imposing on someone and also asking them to decide or excuse themselves on the spot.

You don’t feel much difference because they aren’t ten degrees hotter. OP is mistaken.

Dogs are 1 to 3 degrees Fahrenheit warmer than adult humans not 10. A temperature above 104°F needs urgent veterinary help.

Note that human babies and young children are also warmer than adults by about a degree.

That’s our name for it. If there is a planet or planets circling Kepler 22 they won’t call it Kepler 22.

Similarly any aliens won’t call Earth by that name. For example, Klingons might have called Earth yoSpu’bogh QongDaq until they made contact.

So aliens wouldn’t type Earth into sat nav but whatever they call it. Now that’s a showerthought !

If they haven’t visited us how will they know what the planet is called and how to spell it?

Not really

That makes no sense at all.

Why would it have infinite digits? It is just as like to be 0.

Good question, I was thinking about this the other day. The reason being that development of several fediverse apps has seemingly stalled because the previously active developers have life issues. (I’m not moaning about it, just a straightforward account)

It seems to me that FOSS developers wouldn’t want their projects to be popular. Because that comes with pressure to constantly improve or expand and it takes up more time. So they start a Patreon or similar but that adds more pressure.

When projects are community developed then I see disagreements and personality clashes which increases stress for lead developers.

You’ve inadvertently hit on the beginnings of an apparent paradox to do with the relationship between numbers and the counting numbers

Suppose the largest number you can have is X and the smallest number you can have is -Y. Then between -Y and X, you can count X+Y numbers which is clearly larger than X. But X is the largest possible number so X+Y doesn’t exist.

Agreed, this is the most on topic post we’ve had for a while.

Generally conservation of energy applies in a closed system, so wouldn’t apply at the creation of the system.

(Plus we can’t (yet) be sure what caused the Big Bang if it happened)

I’ve always liked the idea that matter, space and time are the way we observe the interactions of fields. So gravity waves make an interesting idea as to how part of it might work

Did you know there is some evidence that our brains are apparently aware of certain events before they actually happen. This isn’t supernatural but possible evidence of something going on outside of the space time we are familiar with. Or that time is not a straightforward arrow in one direction.

Pulsars are made of matter, which runs into the how did it all start problem (if there was no big bang to create the matter)

Yes, but black holes are an accretion of matter, that as far as we know is locked away until it evaporates. For there to be a net increase in overall matter due to gravitational waves there’d need to be either another source of waves (as in the field theory) or the waves would have to produce matter at a rate in violation of E=mc^2+C (which could be wrong)

Thanks. What mechanism would cause the gravity waves?

I ask because there is a controversial theory that the universe actually consists of a number of interacting fields. They’ve always been there. What we observe as matter, time etc are the result of those fields.

Excuse my ignorance but what is CMB?

It’s written like hairiness is the absence of bald which makes even less sense.

I know three in English so there must be more in other languages
