Discussion Overview

The discussion revolves around the reliability of popular news sources in reporting scientific information, particularly concerning an asteroid's potential impact on Earth. Participants critique sensationalized headlines and the accuracy of reported data, while exploring the implications of hypothetical scenarios related to high-velocity objects.

Discussion Character

  • Debate/contested
  • Conceptual clarification
  • Exploratory

Main Points Raised

  • Some participants express skepticism about the accuracy of sensational headlines from sources like the Express, questioning the credibility of such outlets.
  • There is a notable discrepancy in reported asteroid velocities, with one participant highlighting an initial claim of 581 trillion mph, later corrected to 64,000 mph, suggesting a significant error in reporting.
  • Participants discuss the implications of an object with positive mass traveling at superluminal speeds, with one suggesting it could create more gravity waves than a collapsing black hole, while others question the feasibility of such scenarios.
  • Some participants point out the general lack of mathematical rigor in journalism, implying that journalists may not accurately convey complex scientific concepts.
  • One participant emphasizes the absurdity of sensationalized claims in mainstream media, describing them as deceptive and inaccurate.

Areas of Agreement / Disagreement

Participants generally agree on the sensational nature of popular media reporting, but there is no consensus on the implications of hypothetical scenarios involving superluminal objects or the extent of inaccuracies in the reporting.

Contextual Notes

Limitations include the lack of clarity on the definitions of terms like "gravity wave" and the assumptions underlying discussions of superluminal travel, which remain unresolved.

Life would be so much more exciting.
Here's one from UK's www.express.com:

Of course, it's all very sensational - and they do eventually specify exactly how likely this asteroid is to hitting Earth anytime soon (slim). And one wonders how such a huge thing could "veer off course".

But should it hit Earth, it would hit this fast:
And at the point of atmospheric entry, Asteroid GD37 would likely hit the Earth at a velocity of 581 trillion mph (28.65km per second).
It's that 581 trillion mph that really gets ya. How could we even see such a thing before it struck us? How could we even survive its gravity wave while seeing it?
 
Physics news on Phys.org
It's the Express. Did you expect accuracy?

And what titles the SUN?

Doomsday on X-Mas!
 
Generally we accept news sources about real research, such as this.

It has apparently been updated to correct that exceptionally bad math; 64,000 mph.

That question doesn't mean anything that I can discern.

Must have been a rounding error...

Of course, as we all know, "journalists" have never been known for their skills in complex calculations such as percentages and ratios.

If something with positive mass was traveling at 1000c, I am thinking that would be very disruptive to the neighborhood.
I suppose it wouldn't make sense to talk about its rest mass. But my thought was that it would create more of a gravity wave than your average collapsing Black Hole. But perhaps not. If it was the same as a billion tons appearing across the sky for a millisecond and then gone, that would not be a big deal. If it was better modeled as a continuous string of billion ton masses appearing across the sky for a millisecond, that could shake things up a bit.

I sure hope you're saying all this tongue-in-cheek. o0)

A tachyonic asteroid coming towards us at 1000 times faster than light? Well, we definitely wouldn't see it coming... :confused:

Plus think what it would do to all those physics textbooks.

My basic point was simply to provide an example of something that had gotten into the mainstream press that was sensational to the point of deceptive and absurdly inaccurate as well.
