Hey Fraser, not sure if you’ve highlighted Laura Forcyk’s channel before. I’ve always thought her space industry analysis took a balanced approach between space optimism and engineering/business realism. Her channel @lauraforcyk has more than 200 videos but fewer than 5000 subs.
Oops! Laura Forczyk and @lauraforczyk
Do the trillions of black holes in the universe contribute to the expansion of the universe by absorbing currently undetectable dark matter and dark energy and also contribute to the growth of black holes?
8:30 The best filter I have on whether to pay any mind to "out there" hypotheses is whether the proposer is trying to sell a book. Well researched science isn't published that way.
But interesting theories very well might 😌 there is not a lot of valid science in that area accept that we seem to be alone.
It would be awesome if you could add links to the other channels you're shouting out here in the Patreon description.
