After more than a century of speculation, data seem to confirm that Betelgeuse (the brightest star in the Orion constellation, shown here) has a much smaller star as an orbital companion.
…
Two independent studies found evidence of a star about the same mass as the sun, orbiting Betelgeuse about once every 2,100 days.
You got it wrong - the poster above is not trying to prove the astronomical phenomenon through a show, the poster is saying that the show itself (called Big Bang) is real. It’s simply a joke.
You can use a pinhole to project an image of the sun onto a sheet of paper but not directly as glasses. Look up a ‘pinhole projector’ you can make a pretty good one with an Amazon box.
I can’t see it anyway from my part of the world :( I was just curious because it doesn’t seem like it would be safe, but it was literally taught to me in elementary school.
Are you so deeply entrenched in modern technology that you cannot fathom that a human could comprehend and map future astronomical patterns?
Humans have been doing this since early records of humankind on earth. Loooooong before computers existed. Computers have only been around the last few decades.
IANAP, but isn’t universal expansion understood to be accelerating? How would “weakening forces of nature” account for that? Assuming this energy could be “lost” (breaking an even longer standing and well tested principle of physics), that loss wouldn’t accelerate anything. At best the speed would remain neutral.
The tired light theory is an alternative explanation to the red shift of distant light that says it’s not because distant objects are all moving away from us but instead that the light somehow loses energy as it travels, which lowers its frequency.
There was another alternate theory that suggested everything was shrinking instead of the universe expanding (thus wavelengths seem longer by the time they get to us).
Personally, I’m more “open to the idea” than “sold” for the idea of the universe’s accelerated expansion. I like theories that eliminate the need for dark matter or energy, especially given that the current ones requiring them assume that they make up 95% of everything. It just seems more likely that we don’t understand things as well as we do than to assume we’re right about everything we think but just need to add 19 times what’s already here to balance it all out.
This thing is just a mosaic of ordinary CCDs. I’m sure the name has something to do with it’s specific scientific goals, but that’s not explained at all in this article. They didn’t even attempt to make any kind of connection between the veil and dark energy. Or even between supernovae and dark energy.
