They are also able to pick up weak thermal radiations, such as the body heat of a mammal. This is probably how even blind or deaf dogs are able to hunt well.
In experiments and brain scans, regions of the brain that are activated when processing infrared radiation were activated when an object that was slightly warmer than normal was introduced to dogs. More on Science Mag. India needs free, fair, non-hyphenated and questioning journalism even more as it faces multiple crises.
But the news media is in a crisis of its own. There have been brutal layoffs and pay-cuts. The best of journalism is shrinking, yielding to crude prime-time spectacle. ThePrint has the finest young reporters, columnists and editors working for it. Fudge factor for creation of sapcetime and to power its expansion and to include the Divide by the number of watts in a "standard bomb".
Nuclear bombs are built up upon the current laws of physics. Those same laws do not apply to the first few moments after the BB. The big bang cannot be directly translated into a X tons of TNT amount. The biggest bomb ever built was megatons; so that is 1,,, ,,,,, ,,,,, ,,,, bombs. Tambora started to grumble noticeably in , building up to a cataclysmic eruption in April The eruption flung vast amounts of dust and ash into the atmosphere, cooling global temperatures for months afterwards.
As a result, the following year — — became known as the "year without a summer". Amazing as it now sounds, Tambora was largely overlooked for some years. It was only when scientists, investigating the links between volcanoes and climate, examined ash layers found in Greenland ice cores that the truth was uncovered: no volcanic eruption since had amounted to more than a damp squib compared with Tambora.
Today, New Zealand's Lake Taupo is a serene sheet of fresh water, beloved of crayfish and hikers alike. Not so 26, years ago, when this region was the site of a massive volcanic blast that coated the North Island with ash and rock metres deep. The present-day lake lies in the caldera of the volcano.
The so-called Oruanui eruption was the most recent volcanic event to score the maximum 8 on the VEI — 10 times bigger than Tambora, and times bigger than Krakatoa. Only 47 such "mega-colossal" eruptions are known to have occurred in all of Earth's history. Taupo is still rumbling away, with more than 20 smaller eruptions known since Oruanui.
The image shows Taupo's Mount Ruapehu erupting in June The volcano may have contributed to the extinction of the moas , New Zealand's gigantic flightless birds. In recent years, volcanologists have started talking about eruptions that far outstrip those of common-or-garden volcanoes. Such " supervolcanoes " would include eruptions that release more than cubic kilometres of material. The Oruanui eruption probably managed that, but a surer candidate is Sumatra's Toba blast, which released cubic kilometres of hot rock, ash and dust about 70, years ago.
Like the Oruanui eruption, it formed an enormous caldera, now partly filled by a lake. The vast amount of dust and ash pumped into the atmosphere is believed to have significantly chilled the world, and may be to blame for a collapse in the human population at the time.
Underneath the beautiful landscape of Yellowstone National Park lies a monster. A plume of hot molten rock that rises from deep within the Earth is believed to cause massive eruptions periodically, some of them big enough to be termed supervolcanoes.
The Yellowstone hotspot has gone off three times in the past few million years. The Huckleberry ridge eruption 2. A rather smaller, but nonetheless supervolcanic, eruption formed the Henry's Fork caldera 1. I'm noy sure that Penrose believes it himself, but the theoretical basis does make sense with a couple caveats.
If there are no massive particles left in the universe, then the universe ceases to have scale , and there's no difference between a massively expanded universe and a singularity. The math works, anyhow, though it depends on proton decay, and a bit of hand-waving about neutrinos.
He's smarter than I am and I like the theory for its internal consistency. I read his book a few years ago so I must be some kind of expert. I really liked his book. Mostly, I like the fact that someone is thinking big, and not just iterating on the consensus view. Cosmology, of all disciplines, needs people who think big. Unless the universe isn't within it's own Schwarzschild radius.
That said, this doesn't account for either dark energy or dark matter. Which would require more understanding than we currently have. But if dark matter doesn't decay, then the photons wouldn't become uniformly distributed. Supermassive black hole decay is the one and only time you get to use 'googolyears' as a serious unit. If ever there was a measure of how far Slashdot has fallen intellectually, it must surely be the fact someone just use the word fart about 20 times in a single post in a woefully ineffectual attempt at being funny.
Your post audience must surely be people with an IQ of about That's definitely not the IQ of the average Slashdot of yesteryear. Or are you saying that high IQ individuals are required to be restricted from occasionally observing, enjoying or participating in low-brow humor? That just means he's almost certainly a male in his late teenage years or possibly early 20's. It doesn't have much to do with intellectual skills, only social ones.
And typical slashdot posters have always been deficient in that. Look up the "hot grits" threads, e. The sun outputs We're at a radius about 93,, miles, so to be in this body's comfort zone, we'd have to be.. That extra 15 from the ideal position of the habitable zone doesn't seem to bad.. About two months. In two minutes, this celestial event will have output as much energy as if you converted the moon from matter to energy.
So, who says it's difficult to put into knowable terms how much energy this is? I can't answer that, but if you laid a hundred Olympic sized swimming pools end to end it would be a pretty pointless and wasteful exercise. You just won't believe how vastly, hugely, mind-bogglingly big it is. I mean, you may think it's a long way down the road to the chemist's, but that's just peanuts to space.
Might I, along with the theist who proposed the Big Bang, suggest a more "heavenly" permutation of the multiverse? Lemaitre also counseled that to treat the Big Bang as G-d's creation was wrong. Learn to read history before misusing it. Sorry to hear he had a weakness of self-contradiction in that manner. Still, a strong scientific achievement on what -is- God's creation. You religidiots are so comedically incompetent at arguing and over-confident at the same time, that it's hilarious.
