The thing that bugs me about all these claims of planets and star wobble and theories on how to predict life and all are all based on the latest iteration of conjecture.
The light being examined is really, REALLY ancient. There's no (as far as I can tell) any leeway given to what may be between the star and us - like dust, or any other thing like dark matter (which is a theory) between us and the exoplanet - Honestly?
To me all this planet discovery is about as verifiable as the canals of mars were when I was a kid.
A star "wobbles" after 15 million years of the light traveling to where we can observe it - and It's as definable as the canals of mars were 40 years ago?
Really? I can't say that the people declaring plants and life are wrong - but then again, science about the near planets is woefully lacking.
How can we definitively say that life exists light years away when we're fucking clueless about what is going on under the surface of Europa?
