For the other Astronuts out there

In other words, they don't actually know.
"An international team of scientists has found unexpectedly high levels of the rare radioactive isotope beryllium-10 in samples from the Pacific seabed.
And they believe it could have been caused by a blast of radiation from space more than 10 million years ago.
Beryllium-10 is an isotope - a variant of an element with a different number of neutrons in its atomic nuclei, formed when cosmic rays hit oxygen and nitrogen in the upper atmosphere.
After forming, this isotope falls to the ground in the rain and settles to the bottom of the seabed at a fairly constant rate.
However, when the researchers looked at samples of the seabed from 10 million years ago, they found that the levels of beryllium-10 were almost twice what they had expected.
Study author Dr Dominik Koll, from Helmholtz-Zentrum Dresden-Rossendorf, Germany, says: 'We had stumbled upon a previously undiscovered anomaly.'

Good ole Joni.

UK Scientists Unveil The First Carbon-14 Battery That Lasts 5,700 Years Without Ever Needing a Charge
I remember telling Pops that battery breakthroughs are in the works...

Just a heads-up; could be interesting over the next couple of days, according to this guy.
Its from FB , so can't post the whole thing.

"Jacques van Delft Solar Observations
1d ·
A prominent coronal hole, visible in the latest SDO/AIA 193 Å image (captured April 18 at 10:48 UT), is now nearly directly facing Earth. Coronal holes are regions where the Sun's magnetic field opens outward, allowing solar wind to escape at high speeds.
This Earth-facing position means a high-speed stream of solar wind is likely to reach our planet between April 20 and April 22, potentially sparking enhanced geomagnetic activity. If the solar wind carries a sustained southward magnetic component (Bz), it could lead to auroras at higher latitudes, minor disruptions in GPS, HF radio, and possibly satellite operations."

 

Einstein says there’s a limit…

 

It’s been tested…the effects predicted did occur…no one has taken it to the limit as ultimate proof, but that’s not far away…in terms of travel and communications we know there are ways around this limit. Not break the laws, but work around them to get the same result.

 

I would say no to the first…and light would be affected by gravitational changes yes…I think : ) I think light rarely, if ever actually travels at the speed of light…

 

Saw this in the wee small hours of Thursday while in Inverness walking back to my digs.
Just thought it was a lightning flash, and thought no more of it until I saw the media the next day.
"Experts believe pieces of a small meteor that lit up the night sky over parts of the UK on Thursday have landed on and around Ben Nevis.
Dozens of people in the west Highlands reported an orange glow and a "bang", and the meteor was captured streaking across the sky on doorbell security cameras.
UK Meteor Network (UKMON), which played a part finding Gloucestershire's Winchcombe meteorite in 2021, said the small meteor had travelled from between Mars and Jupiter.
UKMON said it was observed descending to about 12 miles (20km) above the ground and pieces could be scattered across a vast area between lochs Treig and Etricht."
Meteor pieces may have landed on Ben Nevis, say experts - BBC News

 

Great display of Noctilucent clouds over the UK last night. Managed to get this shot looking NW from Stirling Castle.
