General community for news/discussion in the UK.

Less serious posts should go in !casualuk@feddit.uk or !andfinally@feddit.uk
More serious politics should go in !uk_politics@feddit.uk.

Try not to spam the same link to multiple feddit.uk communities.
Pick the most appropriate, and put it there.

Posts should be related to UK-centric news, and should be either a link to a reputable source, or a text post on this community.

Opinion pieces are also allowed, provided they are not misleading/misrepresented/drivel, and have proper sources.

If you think "reputable news source" needs some definition, by all means start a meta thread.

Posts should be manually submitted, not by bot. Link titles should not be editorialised.

Disappointing comments will generally be left to fester in ratio, outright horrible comments will be removed.
Message the mods if you feel something really should be removed, or if a user seems to have a pattern of awful comments.

But is this the same type of light? We're talking about pure heat damage, how do mirrors reflect heat?

Lasers don't send heat. Lasers send light energy that is absorbed by the surface and radiates it as heat.

If a mirror was 100% effective it would work, but the tiny bit that hits the backing of the mirror will melt it and then it'll cascade.
