Ask Ethan: Do signals degrade as they travel through space?
In traveling through the expanding Universe, particles slow down while light and gravitational waves redshift. What degrades and what…Continue reading on Starts With A Bang! » Source link...
No, particle physics colliders cannot ever destroy the Universe
Smashing things together at unprecedented energies sounds dangerous. But it’s nothing the Universe hasn’t already seen, and survived.Continue reading on Starts With A Bang! » Source link...
Can the Drake equation’s final term predict humanity’s demise?
No civilization, no matter how successful, can last forever. What does the non-detection of intelligent aliens mean for our own longevity?Continue reading on Starts With A Bang! » Source link...
Did Hubble’s new “dark galaxy” kill modified gravity?
The discovery of CDG-2, a galaxy that’s more than 99.9% dark matter, could reveal a new population of ultra-faint galaxies. But is it real?Continue reading on Starts With A Bang! » Source link...
Only these six spacecraft will ever escape the Solar System
No human has ever left the Solar System, and only six already-launched spacecraft will ever exit it. Will Voyager 1 remain the most…Continue reading on Starts With A Bang! » Source link...
Ask Ethan: Can quantum entanglement survive a black hole?

Record-breaking natural laser discovered 11 billion light-years away
Forget about the terawatt lasers we’re making on Earth. The Universe makes natural ones thousands of times more powerful than the Sun.Continue reading on Starts With A Bang! » Source link...
How Einstein revolutionized the meaning of “where” and “when”
Even space and time are relative in Einstein’s universe. That means our old notions of “where” and “when” no longer apply on cosmic scales.Continue reading on Starts With A Bang! » Source link...
The 5 biggest obstacles to AI data centers in space
There are plenty of engineering obstacles, and those can be overcome. But you cannot change the laws of physics, and those matter too.Continue reading on Starts With A Bang! » Source link...
