It's possible they are actually talking about the rate of energy given off by the Sun that reaches the Earth. However, they are not talking about the amount of energy released, but rather the rate of energy released. The "laser at Magurele, Romania" is actually part of the Extreme Light Infrastructure, a pan-European research project, described ...

Power of the laser This video shows interviews with people at the laser center. At 4:54 you can see the director of the center repeat the claim. In this video, that same director states that the laser was measured at 10.88 PW or 1.088×10^16 W. Remember that watts (W) are the unit of power. The laser does not operate at that power continuously. Just for ...

No, it seems that the 528hz claim is either completely made up, or at best based off of recordings artificially adjusted to be heard by humans. The Sun simply doesn't oscillate that quickly or that consistently for the claim to be believable. Why 528hz is not realistic: Helioseismology is both an awesome word and the research field concerned with studying ...

Has non-TSI solar output increased over the past century in ways the IPCC climate models ignore? Probably not. What Prof. Shaviv has done is shown that it is possible to make a simple climate model which replicates climate change by adding certain parameters the IPCC does not use. What they have not shown is whether this has any relation to reality. The ...

Probably not. Sunspots may be correlated with climate change. For example, the famous Maunder Minimum is correlated with the Little Ice Age. Causality is a bit trickier since the mechanism isn't well understood, but there is a hypothesis a rise in global temperatures might be partially caused by increased sunspot counts (and the corresponding increase in ...

It's clearly something they imagined, because looking at the details, they are all off in a way that implies a complete lack of understanding of the scales involved. For example, according to the Encyclopedia Britannica Puranic cosmogony accounts for the periodic destruction of the world at the close of an eon, when the Fire of Time will put an end to the ...

This has gone viral. Yes, the risk is high as the article suggests, this number was estimated (or calculated) by physicist Pete Riley, who receives fundings form NASA, NSF, and DoD. His recent publications can be found here. Here is a direct quote from NASA, this was posted on July 25 2014: In February 2014, physicist Pete Riley of Predictive Science Inc. ...

The latest word on this issue seems to be The Impact of the Revised Sunspot Record on Solar Irradiance Reconstructions Solar Physics (2016): Climate sensitivity is uncertain by a factor of about two and may differ for different forcings, but it is generally considered to be in the range of 0.2 to 1 °C per [watt per square meter] forcing. The response ...

Yes, if you use sunscreen. No, if you use sunblock. Sunscreen absorbs an amount of radiation, but not all (sun protection factor is used to measure effectiveness): Sunscreen [...] absorbs or reflects some of the sun's ultraviolet (UV) radiation on the skin exposed to sunlight and thus helps protect against sunburn [1]. Sunscreen combines organic and ...

No, it will miss us, in this orbit, by about 0.428 astronomical units (64 million km, 40 million miles). Here is the latest technical tracking information on "C/2012 S1 (ISON)". It is a Java app that can be used to model the orbits, and is used and vetted by hundreds or thousands of astronomers every night. If you animate the orbit, you will see the you ...

No SkepticalScience discusses various ways people have tried to claim that the sun has caused the recent warming of Earth, and they're just generally not justifiable. There are a number of studies that try to attribute warming just from statistical correlation, like Foster & Rahmstorf 2011, and they inevitably find essentially no solar effect, usually ...

A partial answer, based on the 2011 paper, Quantifying the role of solar radiative forcing over the 20th century, by Shaviv and Shlomi Ziskin: Well, it turns out Shaviv and Ziskin do not make clear positive claims regarding what makes up that contributing factor of solar activity. They only make the basic assumptions that some kind of "Indirect solar/...

The Sun activity changes every 11 years or so. That's called solar cycle, and one of its manifestations are sunspots. Sunspots irradiate more energy so the more spots the more energy the Sun produces. Here is what they look like If we look at the data, we see that the first decade of the 21st century, the number of sun spots has been in decline, that's ...

Well, there are many objects out there that "may or may not" impact Earth. ISON (a "sungrazer," incoming from the Oort Cloud) is headed for a close roundabout of our Sun and may wholly or partially disintegrate or may come back round intact. Earth MAY pass through the remnants of very tiny particles of ISON's pass-through; most, burning up in the atmosphere ...

If it is a spray tan, yes On this page, the word is... Chlorine will break down your spray tan quicker than shower/bath water ...and they note that... this means a swim in a chlorinated pool can help fake tan disasters too so take a dip to get rid of those streaky heels or stained palms Spray tan acts very superficially, on the outermost layer of skin, ...
