Gravitational Waves Also Experience Cosmic Redshift
Ask Ethan: Do gravitational waves redshift like light does? Light redshifts as it travels through the expanding Universe, and is affected by a host of other phenomena. But not everything is the same for gravitational waves. https://t.co/x7HvhjGPU5
Evolving Dark Energy Claims Remain Weak, Puzzles Persist
The flimsy case for evolving dark energy There's been a lot of talk about evolving dark energy, and how DESI data demands it. But the case for this remains somewhat weak, while the true underlying puzzles remain unsolved. https://t.co/Xh1dgGu3kI
Space Megaconstellations Threaten Near-Earth Environment, Urge Resilience
The new Big Think print issue just dropped: on the Roots of Resilience. Here's how we can avoid a space megaconstellation mega-disaster. The current situation, where companies do nothing, is a recipe for destroying our one & only near-Earth environment. https://t.co/FycTO9j4QD
Even a Three‑second Pause Reshapes the Universe
The Universe has changed by the time you finish this sentence It takes just over three seconds to read a typical sentence. In that tiny flash of time, the Universe has changed in tiny but mighty ways. On cosmic timescales, that really adds...
Peculiar Galaxies Reveal Cosmic Violence Behind Galaxy Formation
Peculiar galaxies showcase the beauty of cosmic violence Most galaxies are spirals, with ellipticals and lenticulars making up the next most common types. But peculiar galaxies reveal the in-between steps, showing how modern galaxies are made. https://t.co/IDAhiX1sEr
Dark Energy Keeps Universe Flat Despite Dilution
Ask Ethan: Does dark energy curve the Universe over time? Our Universe was once ruled by radiation and matter, but those densities eventually dilute. Would spatial curvature appear? Even if it did, dark energy now flattens the Universe once again. https://t.co/zF67EySaRB
No Cosmic Hole Exists; Nebula Image Is Misused
The widely reported “hole in the Universe” is a lie It's 2026. There still isn't a hole in the Universe, and the famous nebula they always show when describing it doesn't have anything to do with the Universe at all. https://t.co/91kWOrNZTD
AI Use Stunts Skills at Any Age, Keep Learning
BrainMaxxing: the road less traveled in the age of AI For older people, AI overuse leads to skill erosion. For younger people, AI leads to you never developing those skills in the first place. It's never too late to grow your mind instead. https://t.co/1DY5Eyi0sm
Why Does the Universe Follow Universal Laws?
Ask Ethan: Does nature need to obey laws at all? One of the most profound facts about the Universe is that it obeys the same laws in all places and at all times. But why are there laws that govern it...
A Fifth Force May Exist, Yet Detection Remains Elusive
The case for and against a 5th fundamental force of nature Looking for a fifth fundamental force of nature? It might be out there. But finding one is a much bigger challenge than any experiment or observation is up to, at least, so...
CPT Symmetry: Nature’s Truly Unbreakable Rule
Why “CPT” is the Universe’s most unbreakable symmetry Some symmetries are always preserved, although things could be different if they weren't. But particle physics's CPT symmetry may truly be unbreakable. https://t.co/tcGehBgNs7
Observations Show Universe Is Flat Despite Einstein’s Curvature Possibilities
Einstein showed space can curve, but data reveals a flat Universe According to Einstein, space can take on any curvature depending on what's in it: positive curvature, negative curvature, or zero (flat) curvature. So why is our Universe so flat? https://t.co/fyjYOnXs1d
Future Universe: Darkness Fades, New Light Awaits
How dark will the Universe become? #AskEthan Sure, dark energy will empty out the Universe and galaxies will run out of fuel to form new stars. But that doesn't mean our sky will only get darker. Look forward to the brightness ahead. https://t.co/huqNduzpjh
Relativity Lets You Jump Ahead, Not Live Longer
A quirk of relativity is the closest thing to achieving immortality Even relativity, with all the power of time dilation, won't increase the span of your lived life. But it can take you far into the future, and even to the ends...
NASA's AXIS X-Ray Mission Canceled After 2025 Cuts
NASA’s next X-ray mission, AXIS, has been killed Did you think that the cuts to NASA made in 2025 had all been reversed, and everything is now fine? Think again. NASA's AXIS mission, on account of that 2025 bloodbath, is now dead. https://t.co/gdFHBnGzRJ
