Is Time Travel Impossible?
I still have a problem with "space-time" as a unified thing. This leads to conclusions like time didn't exist before the Big Bang, which I find highly questionable. However, Special Relativity depends upon it. In order for space-time to not exist, we would need a completely different model of the universe.

Quotation of the day
Instead, climate science is being used as a political weapon, and the voices of scientists like me are being ignored or even vilified. I was under the impression that in the United States, all voices and arguments should be heard. Climate science is not settled science. If it was, why would there be a continuous flow of money to research it? For example, is AOC aware that in the fossil fuel era, in spite of a four-fold increase in population, deaths have plummeted?
….
Perhaps we should pause and consider why none of the global warming models from two decades ago have come to fruition. Perhaps we should slow down and think about the consequences of allowing our adversaries to supply the world with cheap energy, because one thing is for sure – wind farms and solar panels won't get the job done.
The objective reader should examine all sides of the climate debate and should ask himself: Are the consequences of acting hastily worse than not acting at all? I think many are skeptical of rushing forward. We must rein in the political hysteria and fear-mongering that is driving the climate change agenda.

Fwd: Asteroids and earth life
Asteroid dust may have triggered massive explosion of life on Earth 466 million years ago
Nearly half a billion years ago, there was a huge explosion of species development on Earth, causing the biodiversity of animals to increase dramatically -- but the true cause of that event has remained a mystery.
In a new paper published on Wednesday in Science Advances, scientists show that the event's onset coincided with the largest documented asteroid breakup in the asteroid belt over the past two billion years.
That breakup, which was triggered by a collision with another asteroid or comet, would have spread enormous amounts of dust throughout the solar system.
"The blocking effect of this dust could have partly stopped sunlight from reaching the Earth – leading to cooler temperatures," the study's co-author Birger Schmitz, a professor of nuclear physics at Lund University, writes in The Conversation. "We know that this involved the climate changing from being more or less homogeneous to becoming divided into climate zones – from Arctic conditions at the poles to tropical conditions at the equator. The high diversity among invertebrates, including green algae, primitive fish, cephalopods and corals, came as an adaptation to the new climate."
Schmitz and his colleagues also studied the distribution of very fine-grained, extremely tiny dust in the sediment, determining its extraterrestrial origin by discovering helium and other substances inside the sediments.
"Our results clearly show that enormous amounts of fine-grained dust reached Earth shortly after the breakup," writes Schmitz.
