... space is not expanding and another force acting on the mass that hasn't been accounted for.
But then how would it be the case that we observe everything moving away from us at the same rate in all directions?
Do they serve alcohol as well?
I wonder how it's possible to find out. Hmmmm....
It's not like you can learn anything or interact with anything [at museums].
That's certainly not true for a museum like the Exploratorium (that also has adults-only nights).
Just use cash, its infinitely easier than all this nonsense.
Before heading out, you have to check whether you have enough cash on hand. If not, you have to stop by the ATM. To pay, you have to pull out your wallet and look through it for the required bill(s). If you pay with large bills, the cashier may opt to examine the bills carefully to ensure they have the necessary security measures signifying that they're genuine currency.
If you choose to pay the exact amount, you also have to pull out coins and pluck out the required ones. If you didn't use coins, then the cashier has to give you change back. You have to accept the change putting the coins in one place and the bills, if any, in another. You should also count the change to ensure the cashier gave you the correct amount.
Yeah, that's so much easier.
Apple pay isn't better or all that different from Google's NFC pay, the difference is that they've done the legwork to build a network of vendors.
The differences are that Apple Pay is easier to set up (just take a picture of your CC card -- no logging in to your bank's web site), easier to use (just put your finger in the sensor -- no turning on the phone, no launching the Wallet app, no PIN to enter), neither Apple nor the merchant has your real CC number (unlike Google), and the kicker is that Apple doesn't track your purchases (unlike Google that brokers every purchase through their Wallet debit card).
Isaac Newton knew that something existed to make the apple fall to the ground, or the planets orbit the sun, but until he spent time studying it, he didn't know what gravity actually was.
Newton never new what gravity actually was; only how to describe its behavior. It wasn't until Einstein that humanity knew what gravity actually was (a warping to space-time).

They can be trade- or service-marked, however.
I don't want to go with iOS, because
... the only way to load software on it is through the app store.
I get that, but how big of a deal is that for you really? (Or, in general, for most people?) Is it a matter of principle or are there apps that you really need that you just can't get from the App store?
