This past week, “Unidentified Aerial Phenomena” videos captured by the Navy were released. The videos, released through the Freedom of Information Act, depict flying objects moving at incredible speeds and performing seemingly impossible aerial maneuvers. One of the videos was shot in November 2004; the other two were shot in January 2015. They have been …
Came across this interview of Helen Sharman (the first British astronaut and first woman to visit the Mir space station): Aliens exist, there’s no two ways about it. There are so many billions of stars out there in the universe that there must be all sorts of different forms of life. https://www.theguardian.com/lifeandstyl … uch-i-know Sharman …
DrNoGods wrote:This, combined with the fact that we do have one planet that supports life, suggests a high likelihood that life exists elsewhere in the universe. Statistically, the probability is very high. Just because we are on a planet with life does not necessarily lead to a high probability life exists elsewhere. As we understand …
DrNoGods wrote: – What empirical evidence is there that any extraterrestrial life exists? To my knowledge there is none at the moment. I agree there is no current empirical evidence for any extraterrestrial life (excluding UFO sightings and alien abductions). In particular, SETI has not come up with anything yet. Given there is no empirical …

Many NASA scientists think we’re on the verge of finding alien life. Ellen Stofan, NASA’s former chief scientist, said in 2015 that she believes we’ll get “strong indications of life beyond Earth in the next decade and definitive evidence in the next 10 to 20 years.” Many astrophysicists and astronomers are convinced that it’s not …

One consequence of general relativity is that the curvature of space depends on the ratio of rho to rho(crit). We call this ratio Ω = rho/rho(crit). For Ω less than 1, the Universe has negatively curved or hyperbolic geometry. For Ω = 1, the Universe has Euclidean or flat geometry. For Ω greater than 1, …
All measurements confirm that the universe is flat (Euclidean). To astronomers, flat means that the usual rules of geometry are observed – light not being bent by gravity travels in straight lines, not curves. But since Albert Einstein proposed that the Universe may be “curved”, the debate has been open. Scientific opinion has moved towards …
This has been mentioned a couple of times in different threads: Anthropic Principle and Intelligent Creation (God) as opposed to Evolution. But, I’d like to put this in its own thread. So for debate. Why is the universe flat? That is, why does it have Euclidean geometry? https://debatingchristianity.com/forum/viewtopic.php?p=87677#p87677
We’ve spent a considerable amount of time on cosmology (over 66 pages). And like other topics in the past (geology, archaeology, etc), we could go forever, but I’m going to wrap up this topic. Going by the evidence that we’re near the center of the universe and without the need to introduce multiple ad hoc …

During the expansion of the universe, the event horizon would collapse as matter/energy moves apart. This would cause gravitational red-shifting. The …
