Nobel laureate John Mather discusses the extended timeframe required for scientists to resolve discrepancies between cosmological theory and observations from the James Webb Space Telescope.
“It's gonna take us a good long time, could be decades before we really, really deeply understand what we were wrong about.”

Mather: Extraterrestrial life is likely frequent but mostly elementary
“I think the answer is, no, we're not alone, and I think life will occur quite frequently, but it will mostly be rather elementary.”

Mather: Unexplained phenomena on Earth are unlikely to be space aliens
“Probably we're not gonna find the neighbors. Similarly, that we're not in danger from the neighbors. So, yeah, maybe we got lots of unexplained things here on planet Earth, but it's not very likely to be space aliens.”

James Webb Space Telescope showed early galaxies grew faster than predicted
“We built the web telescope, it did what it was supposed to do, it produced beautiful pictures, and right away we could see that the galaxies grew even faster than we thought. And so even though we had the information from Hubble and all the simulations and cal…”

Mather: Small Earth-like exoplanets analyzed so far lack detectable atmospheres
“And so, the technique works, and now we're just now busy analyzing the small stars that have potentially small Earth-like planets, and I can't say that we're really surprised, but so far the little ones do not have atmospheres that we can tell.”

Mather: Habitable Worlds Observatory will directly image Earth-like planets
“And the next one we're going to build is called Habitable Worlds Observatory. And so when we do that, we'll be able to see an image with a little dot next to the other Big dot, and it'll be an Earth-like object around a star like the Sun”

Stephen Hawking called COBE map the century's greatest scientific discovery
“Stephen Hawking looked at our map of the pink and blue blobs, and he said it was the most important scientific discovery of the century, if not of all time.”
